Spudding in

"Spudding in," or to "spud" a well, means to begin drilling operations. The drill string, consisting of a drill bit, drill collars, drill pipe, and kelly, is assembled and lowered into the conductor pipe. Drilling fluid, better known as drilling mud, is circulated through the kelly and the drill string by means of pipes and flexible hose connecting the drilling fluid or mud pumps and a swivel device attached to the upper end of the kelly. The swivel device enables drilling mud to be circulated while the kelly and drill string are rotated. The mud pump draws fluid from mud tanks or pits located nearby. The drilling mud passes through the kelly, drill pipe, drill collars, and drill bit. It is returned to the surface by means of the well bore and the conductor pipe where it is directed to a device called a shale shaker. The shale shaker separates the drill cuttings and solids from the drilling mud, which is returned to the mud tanks to be circulated again (fig. 23). As the drill string is rotated in the well bore, the drill bit cuts into the rock. The drilling mud lubricates and cools the drill bit and drill string and carries the drill cuttings to the surface (fig. 23).

Rigging up

The components of the drilling rig and all necessary equipment are moved onto the location with large, specially equipped trucks. The substructure of the fig is located and leveled over the main bore hole (fig. 22). The mast or derrick is raised over the substructure and the other equipment such as engines, pumps, and rotating and hoisting equipment are aligned and connected. The drill pipe and drill collars are laid out on racks convenient to the rig floor so that they may be hoisted up when needed and connected to the drill bit or added to the drill string. Water and fuel tanks are filled. Additives for the drilling fluid (drilling mud) are stored on location. When all these matters have been attended to, the drilling contractor is ready to begin drilling operations (spud the well).

Valves and Actuators

HY Hydraulic Actuator

Actuator HY

The Type HY Hydraulic Actuator is a ratio-piston-type actuator mounted on a reverse-acting gate valve. The HY Hydraulic Actuator is designed to be fail-safe and fail-close. When installed as part of a safety system, it will automatically close with the loss of control pressure and will open automatically when the control pressure is restored.

Functions:

  • The actuators are used on secondary master valve and/or wing valve of Christmas tree, flowlines, header valves, gathering lines and pipelines.
  • As part of a surface safety system, the actuator will shut off flow from the well in the event of a catastrophic event.
  • The HY surface safety valve is a hydraulically controlled actuator that is operated by a closed hydraulic system completely independent of well fluids and pressure.
  • Hydraulic pressure acting on the piston holds the valve open. Loss of hydraulic pressure in the actuator cylinder allows the well or flowline pressure acting on the area of the lower stems to force the stem and gate closed.
  • Recommended for use in high-pressure and/or large-bore applications.

Features:

  • Control line port can be rotated 360°.
  • Hydraulic section is resistant to corrosion.
  • Has a quick-disconnect clamp.

Benefits:

  • In the event of a fire, the metal-to-metal seal between bonnet and lower stem acts as a secondary seal if the stem packing is damaged.
  • Has a back-seat test port and packing leak detection port.
  • Oil port can be rotated 360 degrees for easy alignment of power-source control line.
  • Has a lifting eye to facilitate removing the actuator when mounted horizontally.
  • Two bonnet types are available to cover a wide range of applications. The Type A bonnet is the extended version, and the Type B bonnet is the flush-mounted version.
  • Nipoloy process (electrolysis nickel) is used on hydraulic cylinder and piston for corrosion resistance.


HYW Hydraulic Sheer Actuator

The Type HYW Hydraulic Actuator is a ratio-piston-type actuator mounted on a reverse-acting gate valve. The HYW Hydraulic Wire Shear Actuator is designed to be failsafe and fail-close. The coiled multi-spring assembly provides the added shear force. When installed as part of a safety system, it will automatically close with the loss of control pressure and will open automatically when the control pressure is restored. The wire shear actuator becomes the primary surface safety device during wireline operations. Should an emergency take place while the wireline tool string is in the well, the wire shear actuator is designed to shear the wire and seal off the flow of the well.

Functions:

  • The actuators are used on the secondary master valve. They are the primary surface safety device during a wireline operation.
  • As part of a surface safety system, the actuator will shear the wireline and seal off the flow from the well in the event of a catastrophic event.
  • The HYW surface safety valve is a hydraulically controlled actuator that is operated by a closed hydraulic system completely independent of well fluids and pressure.
  • Hydraulic pressure acting on the piston holds the valve open. Loss of hydraulic pressure in the actuators cylinder allows the well or flowline pressure acting on the area of the lower stems to force the stem and gate closed. The spring package is sized to cut a specific size of wireline.

Features:

  • Coiled spring design provides cutting force.
  • Control line port can be rotated 360°.
  • Hydraulic section is resistant to corrosion.
  • Has a quick-disconnect clamp.

Benefits:

  • In the event of a fire, the metal-to-metal seal between bonnet and lower stem acts as a secondary seal if the stem packing is damaged.
  • Has a back-seat test port and packing leak detection port.
  • Spring packages are designed to fit customer application.
  • FMC Surface Wellhead has provided spring packages to cut various-sized wires. We provide a North Sea operator a wire shear spring package to cut 7/16" braided line (shear force required was 22,400 lbs.).
  • Oil port can be rotated 360 degrees for easy alignment of power-source control line.
  • Has a lifting eye to facilitate removing the actuator when mounted horizontally.
  • Two bonnet types are available to cover a wide range of applications. The Type A bonnet is the extended version, and the Type B bonnet is the flush-mounted version.
  • Nipoloy process (electrolysis nickel) is used on hydraulic cylinder and piston for corrosion resistance.
  • Hydraulic piston is hard chromed for corrosion resistance.


PN Pneumatic Piston Actuator

Actuator PN

The Type PN Pneumatic Piston Actuator is a ratio-piston-type actuator mounted on a reverse-acting gate valve. The PN Pneumatic Actuator is designed to be failsafe and fail-close. When installed as part of a safety system, it will automatically close with the loss of control pressure and will open automatically when the control pressure is restored.

Functions:

  • Actuators are used on secondary master valve and/or wing valve of a Christmas tree, flow lines, header valves, gathering lines and pipelines.
  • As part of a surface safety system, the actuator will shut off flow from the well in the event of a catastrophic event.
  • The PN surface safety valve is a pneumatic-controlled actuator that is operated by an air or gas source.
  • Pneumatic pressure acting on the piston holds the valve open. Loss of pneumatic pressure in the actuator's cylinder allows the well or flowline pressure acting on the area of the lower stem to force the stem and gate closed.
  • Pneumatic actuators can be used in both gas and oil wells. Care should be taken when using pneumatic actuators on high-pressure and/or large-bore applications.
  • One of the opening characteristics of a pneumatic actuator is that once sufficient force is generated to break the differential, the valve will instantaneously go from closed to full open.
  • This causes a slam-open effect that can cause damage to gates and seats. This can potentially damage the actuator. The following are some methods to reduce this potential problem:

      Benefits:

      • Reduce the differential pressure across the valve.
      • Reduce the volume of air in the cylinder.
      • Dampener mechanism.
      • Use of a hydraulic actuator is considered the best option.
      • Loss of control pressure above the piston will cause the actuator to close.
      • In the event of a fire, the metal-to-metal seal between bonnet and lower stem acts as a secondary seal if the stem packing is damaged.
      • Bonnet has a back-seat test port and packing leak detection port.
      • A relief valve on the cylinder prevents over-pressurization.
      • Large piston area permits use of low-pressure air or gas control systems.
      • Rising stem for visual indication.
      • Pneumatic cylinder and piston are electrolysis nickel plated for corrosion resistance, reducing repair cost.

      FMC Valves

      Model 101

      101

      Using the API "PR1+" advantage, the Model 101 gate valve is the most highly tested valve in its class. Designed for non-corrosive, 2,000 to 5,000 psi service, the Model 101’s improved metal-to-metal bonnet gasket provides certifiable durability for AA, BB, and DD trims. The Teflon insert inside the seat allows sealing as low as 25 psi, a key safety feature. Adding more safety and durability, the gate and stem are endurance tested to API PR2 qualifications.

      2" through 3-1/8" sizes, from -20 to 250F, the Model 101 is a low-torque, lightweight valve that opens with only 18 ft-lbs and weighs in at less than 100 pounds. Bi-directional sealing capabilities allow this valve to be used as a wing or annulus valve. In addition, the Model 101’s slab gate design will never mechanically lock, minimizing problems during operation and workover. The compact body minimizes the overall dimensions of the valve, in part due to the non-rising stem that keeps valve height at a minimum.

      Quality at FMC is proven. Through field testing, endurance cycle testing, and service testimonials, the Model 101 gate valve satisfies virtually any low-pressure application for the life of your operation.


      Model 120 & 125

      120

      Part of the 100 series of gate valves, the M0del 120 is our low-pressure, critical service option. Tested above and beyond API 6A PR2 requirements, the Model 120 is available from -75 to 250F, in AA-HH materials, for up to 5,000 psi, while the 125 reaches 6,650 psi.

      Incorporating safety features is always a high priority for the development of products and services at FMC. All 100 series gate valves are equipped with blowout features like threaded and anti-blowout packing nuts, bonnet caps, packing retainers, and stem backseats that hold the stem in place. With a break off point outside the valve cavity, the no pressure will ever escape in a contingency situation. In addition, the slab gate does not mechanically lock so you will never have a problem opening, closing, or servicing the valve. Bi-directional sealing allows installation from any orientation, and the non-rising stem does not allow debris to enter the packing. Details on valve components regarding material properties, coatings, and other related features can be found in the surface wellhead Catalog, available for download here.


      Model 120plus

      120 Plus

      FMC Technologies Model 100plus series valves are the most technically advanced slab gate valves in the oil and gas industry. This new gate valve design is based on more than 20 years of field experience plus 4 years of extensive research and development.

      The Model 120plus valve is available in 3,000 psi and 5,000 psi pressure ratings, and it is qualified for 6,650 psi service. Available in hand wheel operated and adapted for actuator configuration.

      10,000 psi and critical service needs are met by the Model 130 gate valve. Part of the 100 series of gate valves, the M0del 130 is our 10,000 psi, critical service option. Tested above and beyond API 6A PR2 requirements, the Model 120 is available from -75 to 400F, in AA-HH materials, for up to 10,000 psi, while the 135 reaches 12,250 psi, and the 150 reaches 15,000.

      With the same critical safety features as the Model 120, the Models 130 and 135 utilize more metal-to-metal sealing and corrosion-resistant materials. Hardfacing on the gate combined with full metal-to-metal sealing between the gate, seat, and valve body, creates a rugged, durable gate valve with a 20-year design life. The Belleville spring-loaded seat energizes for low-flow, low-pressure sealing, with constant sealing between itself and the gate. At the top of the stem resides the stem packing, and FMC’s patented UV-type energizes under pressure and is inert to all drilling fluids. The stem itself is non-rising and does not drag debris into the stem packing.

      A replaceable lift nut has several advantages – it protects the gate, offers easy replacement, and provides maximum gate float. Without the lift nut (priced that a tenth of the gate) valve repair would be much more costly.

      Secondary Seals

       Secondary seals are used to seal around the production casing stub in the bottom of the bowl of the tubing head. The various types are described below:

       

      Seals

       


      Double FS-Seals
      This design consists of two elastomer-shaped seals located in grooves in the bottom of the tubing head. A seal is achieved by interference of the seal with the outside diameter of the casing and the bottom or OD of its retaining groove. A spring molded in each inside corner of the seal provides an anti-extrusion mechanism when sealing against pressure by bridging the gap between the tubing outside diameter and casing head seal bore. The shape of the seal allows it flexibility to maintain sealing interference with the large variations in tubing outside diameter. 

        PI-Seals
      These seals consist of a T-cap seal element, nonextrusion rings and a receiver ring. These components will fit the HPE bottom prep configuration. The PI seal is designed for use up to 15,000 psi working pressure and temperatures up to 75°F or as low as -50°F, depending on the elastomer selected. It provides the proper compression and squeeze even with the larger API casing tolerances. The design effectively intensifies the annulus pressure and thus the internal stress in the elastomer to minimize the effects of explosive decompression.

        SBMS-II Seals
      This metal-to-metal seal consists of a "U"-shaped ring with a "bump" sealing surface at the outside and inside legs of the "U." When installed, the entry ramp compresses the legs of the "U" inward and creates contact stress in each "bump" that provides the seal. This seal requires the casing stub OD to be field machined after the casing is hung to provide the proper sealing tolerances and surface finish. This is accomplished with a portable pneumatic-driven tool. It is good for temperatures ranging from -75°F to 1200°F.

        RCMS Seals
      The Rough Casing Metal Seal (RCMS) is designed to use up to 20,000 psi. This seal does not require special machining of the casing stub; is compatible with temperatures from -20°F to 350°F in corrosive environments; does not require special installation tools and is simple to install; is NACE compatible; is compatible with casing spool and tubing spool strength; is compatible with casing string strength properties.

      Tubing Heads

       tubing head (n.) - Equipment attached to the casing spool used to hang the tubing (smallest casing string) and seal the annulus between the tubing and casing.

      The top spool on a wellhead assembly contains the highest pressure in the wellhead, and contains a load shoulder to hang the tubing hanger and tubing string. When the well is completed, the tree is installed on top of the head with a tubing head adapter. Providing a means to support and test the BOPs while completing the well, the tubing head is a necessary component when drilling and completing a well. The standard tubing head product line combines a straight-bore profile with a varied number of aligning pins, depending on the chosen model. FMC’s tubing heads eliminate the “wedge-locking” of the bowl protector, BOP test plugs, and tubing hangers. As additional advantages, valve removal (VR) threads are standard on all flanged or studded tubing head outlets, and if a 9” or larger top flange is required, the C-29 casing hanger can be used for casing-type completions.

       

      Tubing Heads

      lockdown screw (n.) - A mechanism that actuates the hanger/packoff seals in the event of annulus pressure, preventing casing movement caused by thermal expansion during production

      Bottom Connections
      Bolt-through flange, studded flange and clamp-hub connections are available. The type and pressure rating used must match the top flange of the previous casing spool or crossover flange. Bolt-through flange connections are the most popular and economical type of connection in certain parts of the world. Clamp-hub connections are sometimes specified, because they are much faster to make up and because they reduce the diameter and weight of the assembly when space limitations are present.

      Top Connections
      FMC Surface Wellhead tubing heads have either bolt-through flange or clamp-hub top connections, which are compatible with all FMC tubing head adapters. The producing pressure of the well normally determines the pressure rating of the top connection.

       

        TC-ET
      With one aligning pin, the TC-ET accepts all of the standard "TC" tubing hangers, with the exception of a dual-completion hanger. Utilizing elastomer seal technology, the TC-ET can be machined with one or two seals in the bottom prep, depending on your operational requirements.

      More economical to recondition after well abandonment, the TC-ET is designed with a straight bowl for maximum efficiency. 


        TCM-ET
      Designed for use with a metal seal, the TCM-ET uses no aligning pins. The option exists, however, to add multiple aligning pins to convert the TCM-ET into the TC-60 or WD-ET for dual completions.  

        TC-60-ET
      A model designed for versatility, the TC-60-ET is one of the most widely used tubing heads in the oilfield. Three aligning pins offer compatibility to either single or dual completion, even in tight-delivery situations. No machining modification is required to adapt this tubing head to your well, regardless of the change in circumstances.

        TC-WD-ET
      The "WD" designation in this tubing head indicates a wedge configuration. The wedge is used for alignment on specific types of FMC tubing hangers, with this particular design allowing for the alignment of multiple-string tubing hangers without external manipulation methods. Like all FMC tubing heads, the TC-WD-ET is of a straight-bore design, more economical to recondition after abandonment.

      Tubing Head Adapters

      tubing head adapter (n.) - Equipment used to adapt the uppermost connection of the tubing head to the lowermost section of the tree.

      Providing a transition from the wellhead to the tree, the tubing head adapter is used for both single and multiple completions. FMC’s standard tubing head adapter product line consists of nine models, each designed to work with a set group of tubing heads and hangers. With threaded, flanged, or studded-top connections, most adapters can be machined with a hydraulic supply inlet for downhole control lines.

       


      A-4 & A-4-M
      A simple transition piece between the wellhead and the tree, the adapter hangs no load nor provide a controlled seal bore. The smooth seal bore on a tubing head is used when tubing is suspended from the tubing hanger. For low-pressure completions, these tubing hangers are not designed for tubing string manipulation or control lines.

      The A-4-M uses a metal seal, whereas the A-4 uses elastomer sealing technology; and is used with the TC-1A-EMS hanger. The A-4 adapter can be used with virtually any tubing hanger configuration. 



      B-2/P, B-1, & A-4-D
      Considered "seal bore adapters" these products have the inside diameter (ID) machined to provide a controlled seal bore for an "extended-neck" tubing hanger or seal nipple. Capable of possessing a test port and/or a hydraulic supply inlet for control lines, seal bore adapters are more commonly used in advanced applications.

      The B-2/P adapter fits with the TC-1A tubing hanger family, whereas the B-1 can be used with or with out a coupling. The A-4-D is intended for use with a dual completion, most often using the wedge tubing head, the TC-WD-ET.



      BO-2 & BO-10
      Known as the coupling-type adapters, the BO-2 and BO-10 provide a means to suspend the tubing in conjunction with a special coupling. Creating a lower connection for the tubing head and an upper connection for the tree, the coupling also accepts a BPV.

      High-pressure completions requiring tubing manipulation through a wrap-around packoff, needing a BPV, or an inlet for control lines, work well with a coupling adapter. With an ACME thread machined into the adapter’s bottom ID to be utilized in conjunction with the coupling, the adapter can be installed. In addition, when a tree is trimmed for critical service (H2S, chlorides), using the coupling adapter with a coupling nut prevents galling of threads between the adapter and coupling on makeup, a feature provided by FMC.

      The BO-2 is installed as an entire assembly by rotating it onto the coupling, and is used as a studded top connection only. The BO-10 installs without the rotation of the tree, and is also solely a studded top connection.



      A-3-EC & A-5-EC
      The Electro-submersible Pump (ESP) adapters, designed with seal bores, accommodate both a tubing hanger neck seal and an electrical power feed-through device. Standard ESP adapters are equipped with rotating flanges to makeup to the tubing head, to minimize alignment concerns. By nearly eliminating the concern for proper alignment, the ESP hanger and tubing head flange are much simpler to install. The ESP product family is available for 3,000 – 5,000 psi applications.

      Tubing Hangers

      tubing hanger (n.) - Mechanism used to hang the tubing from within the tubing head by means of a thread.

      These load-bearing devices are installed in the top bowl of the tubing head and are run through the BOP. Also doubling as a means to access and manipulate additional smaller tubing lines that are utilized downhole and extended to the surface on the outside of the tubing string(s). Available for any type of single/multiple completion, most FMC tubing hangers accept a BPV that seals the tubing bore. Some hangers are ported for hydraulic control lines, SSSV’s, or other types of completion equipment.

      casing spool

       casing spool (n.) - Equipment responsible for hanging the next casing string.

      Designed with a bowl containing a load shoulder, each casing spool in the wellhead stackup hangs each casing sting after the casing head and before the tubing head. The bottom prep of the spool has been engineered to contain a packoff seal and flange for either a clamp-hub or a standard flange connection. For annular access, either studded or line pipe outlets can be machined into the spool.

      Providing a controlled bore in the top bowl for the casing hanger seal, it also provides a seal in the bottom bowl to pack off the previous casing string and isolate the ID seals from internal casing pressure. An additional function of the casing spool is to allow for testing BOPs while drilling, retaining the bowl protector, and pressure-testing casing seals through a test port.

       

      Casing Spools

        C-22-EG
      This straight-bowl casing spool eliminates the need for lockdown screws to retain the bowl protector, creating fewer leak paths than other standard casing spools and prevents wedge-locking of pressure-energized parts (hangers, test plugs). This model accepts C-21, C-24, and C122 casing hangers, and is formulated for use with C-22-BOP test plugs.

      Threaded, studded, or flanged outlets can be machined to access the annulus, depending on your well. Bottom prep options range from metal seals to proprietary non-metallic seals, also determined by your well conditions and requirements. 



      C-29 & C-29-ET
      Industry standard C-29 bowl sizes are found in both the C-29 and the C-29-ET, the –ET version designed to utilize lockdown screws in the top flange. Lockdown screws retain the hanger and energize the integral packoff seal. With a bowl deeper than that of the C-22 product line, these spools accept all HP/HT developed casing hangers, and are available with one of several bottom prep options, ranging from elastomer bushings to rough casing metal seals.

      Casing Heads

      casing head   (n.) - The lowest part of the wellhead that is almost always connected to the surface casing string, and provides a means of suspending and packing off the next casing string.

      Providing attachment to the surface casing string through the type of bottom connection (Slip-on-weld, threaded, Sliploc), the casing head is typically qualified to withstand up to 10,000 psi working pressure. It suspends the casing and packs off the next casing string while providing annular outlets, as well as supporting the BOP while drilling the remaining stages.

       

      Casing Heads

      C-22-EG
      Accepting the C-21 and C-22 –type casing hangers, the standard C-22-EG head is an API standard. It eliminates the need for lockdown screws to retain the bowl protectors, creating fewer leak paths. The bottom prep of the casing head can be machined to fit a variety of applications.

      The straight bowl design prevents the wedge-locking of bowl protectors, casing hangers, and test plugs, simplifying the installation process. Like all FMC casing heads, the C-22-EG has the option of a detachable base plate, another time-saving feature.

      Safety: No need to work under a suspended BOP.

      Casing Hangers

      casing hanger  (n.) - Mechanism that locks into the casing head, responsible for hanging the casing pipe.

      Developed to last 20 years with proper maintenance, FMC’s casing hangers are available to fit a multitude of well environments. Slip hangers seal automatically or manually, depending on the types of seals integral to their installation.

       

      Casing Hangers

       


      C-21 & C-24
      Designed with a "Type H" seal ring as a feature, these manual casing hangers are designed to use the seal as an additional packoff (which is independently installed) to provide an energized seal. These hangers fit standard FMC wellheads and can be lowered through the BOP before or after the cement has been set. With easily engaging, latching cap screws, the C-21 & 24 casing hangers are quick to install.

      Designed with a "Type H" seal ring as a feature, these manual casing hangers are designed to use the seal as an additional packoff (which is independently installed) to provide an energized seal. These hangers fit standard FMC wellheads and can be lowered through the BOP before or after the cement has been set. With easily engaging, latching cap screws, the C-21 & 24 casing hangers are quick to install.



      C-22 & C-29
      Adaptable to all C-22 and C-29 casing heads, the C-22 slip hanger is designed to suspend average casing loads. This type of hanger provides automatic packoff sealing at only 50,000 pounds of casing load. It is also suitable for short casing or lightly loaded applications.

      Lowered through the BOP and landed either before or after the cement has set, the C-22 incorporates a spring-loaded latch, interlocking slips, and a heavy-duty hinge into its efficient design. The slips engage the casing evenly, thus distributing the casing load equally to the bowl of the casing head. Enhanced over time to become an industry standard, this hanger is available for off-the-shelf delivery. 


       

      C-121S
      The C-121S casing hanger is made for a C-29 casing spool to hang heavy casing loads in potentially harsh environments. Difficult applications include high pressure, high temperature, or highly concentrated chlorides or H2S situations.

      With two options for packoff energization, this hanger can be used to meet a multitude of needs to suit your specific operation. Similar to our standard casing hanger product family, the C-121S has a split-bowl design with a compression packoff above the slips, and it incorporates locking slip segments with a non-extrusion plate.



      C-122 & C-129
      This line of casing hangers takes on a higher load capacity than our standard product line. When drilling in HP/HT environments, the C-122 & 129 slip hangers can provide additional features, like automatic packoff sealing.

      Compatible for use in C-22-EG, C-29, and C-29-ET casing spools, the C-122 and C-129 casing hangers use tangential bolting as a means of incorporating the split-bowl design. The patented non-extrusion plate further enhances the sealing capability of the hanger under both light and heavy casing loads, for a design life of up to 20 years.


       

      C-229
      Designed specifically to fit FMC’s C-29-ET casing heads and spools, the C-229 casing hanger handles extreme casing loads and pressures. Similar to the C-121S, the harsh environments for which the C-229 is suitable are high H2S, chlorides, and HP/HT. The automatic packoff sealing that comes from the extensively tested elastomer seals is located above the slips, and incorporates the split-bowl design.
