WOM is licensed under API 6A and API 16A latest edition and has a fully implemented API Q1 quality system. The API 16A license not only applies to drill-thru equipment, but also Ram and Annular Type BOP’s. WOM is certified to ISO 9001.

Designed to NACE MR-01-75 Materials Standards for resistance to sulfide stress cracking are standard.

Typical WOM WGK Annular and WU Ram Type BOP Assembly

WOM’s BOPs

5


Ram Packing is generous and self-feeding

Operating Pressure is moderate, due to large piston area

Ram Change is quick and easy

All Working parts and control fluid passages are enclosed

Well Bore Pressure assist in holding rams closed

(2) Seals and a vent hole prevent well pressure from bleeding into operating cylinder

All Operating parts can be replaced on location

The “U” BOP is the most widely used BOP type in the world today. Its simple, compact design makes it well suited for operations offshore and onshore.

The one piece type “WU” ram provides a pressure energized seal and maximum contact area to the drill pipe.

WOM’s ram type BOP operating system is designed to provide a fast and reliable closure around pipe or casing in the well bore. The sealing is energized by the pressure and is maintained even with loss of closing pressure.

Rams can be locked in closed position by optional wedge locks, locking screws and or hydraulic operating pressure

WU Ram Type BOP

�


The capital letters in the following designations refer to the WU BOP dimensional views and dimensions tables on page 5 and 6.

The following applications apply to typical WU type BOPs.

Side outlets to 4-1/16” can be provided beneath each set of rams on either or both sides of WU BOPs. Side outlets can be studded, open-faced flange, or clamp hub.

Flanges conform to API standard 6A and/or 16A. Hubs conform to API 16A or applicable standards. Type 6BX flanges are standard for 10,000 and 15,000 psi working pressures and for 5,000 psi for 13-5/8” and larger bore BOPs.

Hydraulic control connections for operation of rams and bonnets are 1” NPT. There are (2) connections for each set of rams. Wedgelock connections are 1/2” NPT.

The dimensions table (page 5 and 6) does not include spacers between rams for double ram models. WU BOPs with spacers to clear tool joints available upon request.

Large bore shearing bonnets are available for shearing high strenght pipe.

All WOM WU BOPs are suitable for H2S service as standard.

The WU BOP can be outfitted with Blind rams, Shearing/Blind rams, Pipe, Casing, or Tubing rams, or Variable bore rams.

The ram close hydraulic circuit is shown in red on the above caption. The closing ratio (the ratio of well pressure to operating piston pressure needed to close rams) for most Type “WU” Preventers is 7:1. The ram closing pressure also serves to open the bonnets for ram change. When the bonnet bolts are unscrewed and closing pressure is applied, pressure pushes the ram inward and at the same time moves the bonnet away from the Preventer body. Even though the ram moves inward, the bonnet stroke is sufficient to bring the ram into the clear for handling. An eyebolt is furnished on each end of the Preventer body which can be screwed into the top of each ram for lifting.

The ram open hydraulic circuit is shown in gray on the above caption. Ram opening pressure also serves to close the bonnets. Hydraulic control pressure draws the bon-nets tightly against the Preventer body; bolts serve only to hold bonnets closed. An im-portant feature of the Type “WU” hydraulic system is that the rams are pulled back close to the bonnets before the bonnets begin moving toward the Preventer body. Because of this, rams never interfere with pipe in the hole or otherwise obstruct the vertical bore. Rams may be changed, in an emergency, when the well is blowing, thereby increasing the security provided by the Preventers.Pressure Required: The rated continuous working pressure for the Type “WU” BOP operating system is 1,500 psi. Pressures of 300 to 500 psi normally provide satisfactory operation. Pressures in excess of 1,500 psi may be required in 10,000 and 15,000 psi Preventers to close the rams against high well pressures. In emergencies, pressures up to 5,000 psi can be applied to the hydraulic controls. For optimum seal life, the applied hydraulic pressure should be limited to 1,500 psi, especially when it is customary to hold “ram open” pressure on Preventers continuously. When a 3,000 psi accumulator is used to store maximum energy for Preventer operation, a pressure regulator should be used to control pressure applied to the Preventer.

Operating Fluids: Light hydraulic oil is the recommended operating fluid for Type “WU” Preventers. Any type is satisfactory except fuel oil, which causes rubber seals to swell and deteriorate. The use of water as an operating medium is satisfactory provided soluble oil is added to prevent corrosion and antifreeze is added when necessary. Should an emergency require the use of drilling mud pressure to operate a Preventer, the Preventer should be torn down, thoroughly cleaned and all seals carefully checked for excessive wear as soon as practical thereafter.

WU BOP Pipe RamsWU BOP pipe rams are available to fit a wide variety of tubing, drill pipe, drill collar, and casing sizes. All rams are suitable for H2S service per NACE specifications. WU BOP ram packers are self-feeding with a large reserve of elastomer to ensure a long-lasting seal under all conditions. Ram packers lock into place and cannot be dislodged by well flow.

WU BOP Variable Bore RamsOne set of WU BOP variable bore rams can be used to seal on a range of pipe. WOM’s WU BOP variable bore ram packers contain steel reinforcing inserts similar to those in the annular BOP packer. The inserts rotate inward when the rams are closed so the steel provides support for the rubber which seals against the pipe.

WU BOP Shearing Blind RamsWU BOP shearing blind rams shear the pipe in the hole, then bend the lower section of sheared pipe to allow the rams to close and seal. Shearing blind rams can be used as blind rams during normal drilling operations.

WU BOP Ram P/Ns

WU BOP Care and MaintenanceDailyorTripCare: All BOPs should be operated daily. Blind

rams should be operated every time pipe is out of the hole. Pipe rams should not be closed except when pipe is in the preventer, to avoid extruding the packer.

CareBetweenWells: Whenever a preventer is removed from a drilling hookup, it should be carefully cleaned, the rams removed, cleaned, inspected, and lubricated. Also, the ram bore should be cleaned, inspected, and lubricated. Any burrs or galled spots should be buffed. The operating system should be thoroughly flushed to remove sediment or foreign material.

Periodic Overhaul: Annually, or more often depending on the type of service, a preventer should be completely disassembled and all parts cleaned, inspected, and reconditioned or replaced. All rubber seals should be replaced except ram packings which should be replaced according to condition.

Testing: At regular intervals, weekly if possible, the complete drilling hookup and choke manifold should be tested for pressure holding ability and correct operation.

Lubricants: (Ram Lubricant) Any water resistant grease or heavy oil can be used as a ram and ram bore lubricant. (Thread Lubricant) Metallic Zinc Base Grease.

Storage: When a preventer is put in storage, the rams should be removed and the preventer thoroughly cleaned, all moving parts greased, and all machined surfaces oiled and greased, particularly the ram bores and the flange ring grooves. Preventers in storage should be filled with a hydraulic fluid.

WOM’s WU Ram Type BOP

1�


WGK Annular Type BOPWOM’s Type “WGK” BOP was designed especially for surface installations.

The “WGK” is a universal annular blowout preventer with a long record of proven, quality performance.

Standard operation requires both opening and closing pressure.

Seal-off is effected by hydraulic pressure applied to the closing chamber which raises the piston, forcing the packing unit into a sealing engagement.

Any normal closing unit having a separate pressure regulator valve for the annular BOP and sufficient accumulator volume can be used to operate the WGK.

The WGK is designed to be well pressure assisted in maintaining packing unit seal off once initial seal off has been effected. As well pressure further increases, closure is maintained by well pressure alone.

Large Pressure Energized Seals are used for dynamically sealing piston chambers to provide safe operation, long seal life, and less maintenance.

Piston Sealing Surfaces Protected by Operating Fluid lowers friction and protects against galling and wear to increase seal life and reduce maintenance.

Operating Chambers are Tested to Full BOP Working Pressure to ensure strength, reliability, and the ability to over-pressurize the chambers in emergencies.

WGK Annular Type BOPOnly Two Moving Parts (piston and packing unit) on the Annular BOP mean few areas are subject to wear. The BOP is safer and more efficient, requiring less maintenance and downtime.

Long Piston with a length to diameter ratio approaching one eliminates tendencies to cock and bind during operations with off-center pipe or unevenly distributed accumulations of sand, cuttings, or other elements. This design enhances the ability of the packing unit to reopen to full bore position.

Conical Bowl Design of the Piston provides a simple and efficient method of closing the packing unit.

Field Replaceable Wear Plate in the BOP Head serves as an upper non-sealing wear surface for the movement of the packing unit, making field repair fast and economical.

Maximum Packing Unit Life is possible with the provision for measuring piston stroke. This measurement indicates remaining packing unit life without disassembly and ensures the longest and safest use of the packing unit.

Three Choices of Packing Unit Rubber Compounds permit more flexible applications.

Screwed Head Design of the WGK BOP is a simple, efficient, and strong method of connecting the head to the body for safe operation with no loose parts to be lost down hole or overboard.

WGK BOP Care and Maintenance (Screwed)Inspect upper and lower connections for pitting, wear, and damage; especially in ring grooves and stud bolt holes. Worn or damaged ring grooves must be welded, machined, and stress relieved. Worn or damaged stud bolt holes can be drilled and tapped to the next larger size and fitted with step-studs.

Check the body for wear and damage-especially in the internal cylinder walls for pits and vertical scores. Minor pits and scores can be removed in the field with emery cloth. Repaired surface should be coated with silicon grease or castor oil. Severe pits and scores may require machining and/or welding which should be performed in a WOM approved machine shop.

Inspect the vertical bore for wear and damage from drill string and drill tools; especially in the area of the ring grooves. If wear is excessive, the area must be repaired.

Check the inner body sleeve for wear, damage, and looseness. Check slots in sleeve for cuttings which may restrict piston movement.

Check for piston damage and wear; especially the inner and outer walls for pits and vertical scores and the tapered bowl for pits and gouges. Minor pits and scores on the walls can be removed in the field with emery cloth.

Check the wear plate in the inner bottom face of the head for wear. In addition to the aging process of time and use, wear of this metal surface is produced by the combination of vertical and lateral forces.

Inspect the packing unit for wear, cracking, hardness, and correct elastomer composition.

Check seal ring for nicks, cuts, fraying of lips, and abrasion. Worn or damaged seal rings should be replaced.

Hydraulic Control SystemThe surface hookup of the WGK connects the hydraulic control lines to the opening and closing chambers of the BOP.

Pressure applied to the closing chamber raises the piston and effects the initial seal between the packing unit and drill pipe. Well pressure or test pressure also acts on the piston below the sealed off packing unit and further increases the closing force acting on the packing unit. As the well pressure or test pressure exceeds the required level the preventer is maintained closed by well pressure alone. As well pressure increases, the closing force on the packing unit also increases. Closing pressure should be proportionally reduced as well pressure is increased in order to maintain optimum closing force on the packing unit and prolong packing unit life.

During normal drilling operations, it is recommended that the pressure regulator valve for the WGK be set at the initial closing pressure for the size pipe being used. This pressure will ensure that initial seal off is achieved should a “kick” be encountered.

During BOP testing operations, once initial seal off is achieved, closing pressure should be proportionally reduced as well pressure is increased.

Exploded View - WGK BOP (Latched)

WGK Annular Type BOP (Latched)WOM’s Type “WGK” BOP was designed especially for surface installations and is also used on offshore platforms.

The “WGK” is a universal annular blowout preventer with a long record of proven, quality performance.

Standard operation requires both opening and closing pressure.

Seal-off is effected by hydraulic pressure applied to the closing chamber which raises the piston, forcing the packing unit into a sealing engagement.

Any normal closing unit having a separate pressure regulator valve for the annular BOP and sufficient accumulator volume can be used to operate the WGK.

The WGK is designed to be well pressure assisted in maintaining packing unit seal off once initial seal off has been effected. As well pressure further increases, closure is maintained by well pressure alone.

Large Pressure Energized Seals are used for dynamically sealing piston chambers to provide safe operation, long seal life, and less maintenance.

Piston Sealing Surfaces Protected by Operating Fluid lowers friction and protects against galling and wear to increase seal life and reduce maintenance.

Operating Chambers are Tested to Full BOP Working Pressure to ensure strength, reliability, and the ability to over-pressurize the chambers in emergencies.
