Annular Blowout Preventers
Hydril's complete line of annular blowout preventers is based on more than 55 years of application experience in all BOP types, sizes, and pressure ranges. There is a Hydril Annular BOP to meet most operational requirements in the petroleum industry today, both on the surface and subsea.
Hydril designs are durable for dependable and efficient operation. A standard annular BOP will strip drill pipe and tool joints. The packing unit life is reduced when used for stripping operations. It will also close off the annulus or open hole to full working pressure.
The Hydril Annular BOP provides quick, positive closing action with simplified controls to keep drilling fluids in the hole when a blowout threatens. The universal seal off feature of the annular blowout preventer permits closure and seal off on drill pipe, kelly, tool joints, or tubing and wireline as well as the open hole. Maintenance of the BOP is easy, rapid, and economical with the use of standard tools.
The Low Alloy Steel Pressure Vessel represents Hydril's
50 years of experience in producing BOPs to provide optimum strength and stress distribution control. Full-spectrum testing meeting or exceeding API require-ments ensures that the desired safety factors and reliability are provided in each unit.
Finite Element Analysis of the body design is the
most advanced, in-depth technique of pressure vessel design analysis and ensures a structurally sound body configuration.
Shell (Hydrostatic) Testing of the BOP body meets the
API accepted industry standards to provide a safe, reliable blowout preventer.
API 16A is the latest API specification covering drill
through equipment. Hydril is licensed to manufacture Blowout Preventers to these exacting standards. In addition, Hydril preventers may also be certified by such certifying authorities as Det Norske Veritas (DNV), American Bureau or Shipping (ABS), or Lloyds of London.
Operating Chambers are Pressure Tested to rated
working pressure of the BOP or 3000 psi, whichever is
greater. This ensures strength, reliability, safety, and
the ability to over-pressure the chambers in well-control situations.
Stainless Steel and Inconel-lined Ring Grooves are
available as options.

ANNULAR BOP
The GX . . . the field proven flagship preventer
of Hydril's fleet
The GX offers extra performance and serviceability while retaining the field proven features of Hydril annular BOPs.
The GX delivers extended operating service with few packing unit changes, with a design that is simple and easy to maintain in both surface and subsea operations.
The GX will close on virtually any drill stem member or seal off the open bore. Operating volumes are lower, resulting in faster closing times and smaller accumulator requirements. Packing Unit fatigue and stripping life have been increased beyond previous industry levels for equiva-lent sized Annular BOPs.
The GX allows full control of packoff tightness during stripping operations, regardless of wellbore pressures.
The structural design, quality and testing of the GX continues Hydril's state-of-the-art advances.
Here are the field proven Hydril features the GX provides:
■ Simple design – only 2 moving parts, thus fewer areas
are subjected to wear meaning less maintenance and downtime.
■ Proven operating principle provides full packing unit
seal off at maximum working pressure on open hole, casing, drill pipe, tool joints, kelly or tubing.
■ Long piston design for optimum stability and reliable
operation.
■ Latched Head for fast and easy access to packing unit
and seals.
■ Opening Chamber Head to prevent inadvertent
contamination of the hydraulic system during packing unit replacement.
■ Four large pressure energized lip seals are used for
dynamically sealing piston chambers.
■ Replaceable Wear Plate eliminates metal to metal
contact between the packing unit inserts and the BOP head,making field repair fast and economical.
■ State-of-the-art structural design, quality and testing
for optimum reliability.
■ Stainless Steel Lined Connection Ring Grooves for
corrosion resistance.
■ Meets NACE MR-01-75 Material Standards for resistance
to sulfide stress cracking.
■ Fabricated from quench and tempered low alloy steel
suitable for service in both low and high temperature applications. GX 18 3/4"-10,000 psi LATCHED HEAD WEAR PLATE PACKING UNIT OPEN CHAMBER HEAD OPEN CHAMBER LIFTING SHACKLES CLOSING CHAMBER
Balanced Piston
Piston stability is assured by Hydril's time proven long
piston design with contact points providing a
length-to-diameter ratio approaching 1. This design eliminates
any tendency to cock and bind during operations with
off-center pipe or unevenly distributed accumulations
of sand or cuttings.
The GX piston is completely balanced. The opening
and closing chamber areas are of equal size. This
equalizes the hydrostatic forces exerted on the piston
by the control fluid column in subsea operations. The
result is a BOP that utilizes a constant closing
pressure regardless of water depth or mud weight.
This piston design is such that the closing pressure
requirements are virtually independent of well bore
pressures.
Contoured angular tapers on the piston bowl
compress and displace the reservoir of feedable
rubber in the back of the packing unit. This design
assures optimum rubber feeding and closing
efficiency. Movement of the piston to the open position
allows the packing unit to relax to full open bore.
Stripping
The design of the GX effectively controls
positioning of the inserts. When
stripping, the inserts remain fixed as the
rubber flows in and out, allowing
the alternating diameters of pipe and
tool joints to pass through the closed
packing unit.
This results in a dramatic increase of the GX
packing unit stripping life – to approximately
twice that of similar sized annular BOPs.
Extra Packing Unit Life
The heart of any annular BOP is its packing unit – and
the GX is no exception. Its packing unit has a greatly
increased reservoir of high-quality feedable rubber.
Because the reservoir of feedable rubber is larger, the
GX permits continuous rubber feeding as the bore
surface wears.
The packing units reinforcing flanged steel inserts
are driven by the rubber during closure and quickly
reach a fixed position where they form a steel ring to
support the rubber from upward motion under wellbore
pressure.
Once the inserts reach their fixed position, rubber
continues to flow inward, effecting a positive seal off
on the drill string or the open bore.
The rubber is primarily in compression and is
there-fore resistant to tears, cuts and abrasions. The steel
inserts stabilize the rubber and control the flow pattern
to minimize rubber stress.
Packing unit life due to routine testing at full working
pressure has been increased beyond previous levels.
Because Hydril Company LP manufactures all its own
packing units, rigid quality control is assured and field
performance enhanced.
More Precise Control
Tool joints can be stripped through the closed packing
unit while a full seal is maintained on the pipe.
The GX packing unit design permits precise control
of packoff tightness, regardless of wellbore pressures.
This allows a slight drilling fluid leakage to be
achieved during stripping operations to provide
lubrication, optimize pull through forces and prolong
packing unit life.
The result is the ability to strip long strings of pipe
and tool joints in or out of the hole at higher wellbore
pressures.

The GK Annular Blowout Preventer was designed especially for surface installations and is also used on offshore platforms and subsea. The GK is a universal annular blowout preventer with a long record of proven, quality performance.
Only Two Moving Parts (piston and packing unit) on the
Hydril Annular BOP mean few areas are subjected to wear. The BOP is safer and more efficient, requiring less maintenance and less downtime.
A 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.
The Conical Bowl Design of the Piston provides a simple
and efficient method of closing the packing unit. With the piston serving as a sealing surface against the rubber packing unit, there is no metal-to-metal wear on the sealing surface and thus longer life results.
A 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.
Two Choices of Packing Unit Rubber Compounds
permit more flexible applications.
The Screwed Head Design of the GK 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 the hole or overboard.
The Latched Head Design is available on the GK,
13-5/8"-5000 and larger BOPs. It provides fast access to packing units and seals for minimum downtime with no loose parts to be lost down hole or overboard.
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 time.
The Operating Chambers are Tested to Full BOP Working Pressure to ensure strength, reliability, and the
ability to over-pressurize the chambers in emergencies.
Meets NACE MR-01-75 Material Standards for resistance
to sulfide stress cracking.

WEAR PLATE PACKING UNIT HEAD OPEN CHAMBER PISTON CLOSING CHAMBER
The GK BOP has been developed especially for use on surface installations but it is also used subsea. 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 GK.
The GK 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. Exceptions are the GK 7-1/16"-15,000 and 20,000 psi which are not well pressure assisted and closing pressure must be maintained on the BOP to assure seal off. (Refer to the operators manual for closing pressure curves.)
Stripping Operations
During well control operations, drill pipe can be rotated and tool joints stripped through a closed packing unit, while maintaining a full seal on the pipe. Longest packing unit life is obtained by adjusting the closing chamber pressure just low enough to maintain a seal on the drill pipe with a slight amount of drilling fluid leakage as the tool joint passes through the packing unit. This leakage indicates the lowest usable closing pressure for minimum packing unit wear and provides lubrication for the drill pipe motion through the packing unit.The packing unit life is reduced when used for stripping operations.
The pressure regulator valve should be set to maintain the proper closing chamber pressure. If the pressure regulator
valve cannot respond fast enough for effective control, an accumulator (surge absorber) should be installed in the closing chamber control line adjacent to the BOP – precharge the accumulator to 50% of the closing pressure required. In subsea operations it is sometimes advisable to add an accumulator to the opening chamber line to prevent undesirable pressure variations with certain control system circuits.
Recommended test pipe for maximum packing unit life.

GK-13-5/8 5000 HL Screwed Head
Hydril's new Compact GK Annular BOPs are lighter and
shorter than previous models. They are designed for use on surface installations, both drilling and workover applications. The new compact models incorporate the following features that have given the GK a long record of proven and quality performance.
Only Two Moving Parts (piston and packing unit) mean
few areas are subject to wear. The GK is safer and more efficient, requiring less maintenance and less downtime.
The Long Piston has a length to diameter ratio
approach-ing one. This eliminates tendencies to cock and bind durapproach-ing operations with off-center pipe or accumulations of sand, cuttings, or other elements that are unevenly distributed.
Conical Bowl Design of the Piston provides a simple and
efficient method of closing the packing unit. With the piston serving as a sealing surface against the rubber packing unit, no metal-to-metal wear occurs on the sealing surface, result-ing in longer life.
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.
Two Choices of Packing Unit Rubber Compounds
per-mit more flexible applications.
Screwed Head Design is a simple, efficient, and strong
method of connecting the head to the body for safe opera-tion, preventing loose parts from falling down the hole or overboard.
Large Pressure Energized Lip Seals dynamically seal the
piston chambers, allow safe operation, provide long seal life, and require less maintenance.
Piston Sealing Surfaces Protected by Operating Fluid
lowers friction and protects against galling and wear to increase seal life and to reduce maintenance time.
Operating Chambers are Tested to Full BOP Working Pressure to ensure strength, reliability, and the ability to
overpressure the chambers in emergencies.
Stainless Steel Connection Ring Grooves are optional. NACE MR-01-75 Material Standards for resistance to
sul-fide stress cracking are standard.

DIVERTERS/BLOWOUT PREVENTERS
Hydril MSP-2000 psi
The MSP Annular Blowout Preventer is applicable to subsea or surface installations requiring a 2000 psi universal blowout preventer. As proven by its many field installations, it will deliver long, dependable service life. This BOP will seal off drill pipe, kelly, tool joints or tubing and wireline or completely shut off the open hole to full rated pressure.
The following outstanding features of the MSP BOP make it qualified to meet the industry's need for simple and reliable blowout protection. A helicopter lift model of the MSP 21-1/4–2000 is also available.
The Screwed Head Design of the MSP 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 the hole or overboard.
The Latched Head Design which is optional on the MSP
21-1/4–2000 BOP provides fast, positive access to the packing unit and seals for minimum maintenance time.
Only Two Moving Parts (piston and packing unit) on the
Hydril Annular BOP mean few areas are subjected to wear. The BOP is thus a safer and more efficient mechanism requiring less maintenance and less downtime.
Back to Front Feedable Rubber on the Packing Unit
enables the packing unit to close and seal on almost any shape in the drillstring or close off the open bore and to strip tool joints under pressure. This safety feature permits confi-dent closure of the BOP at the initial indication of a kick with-out the delay of locating the tool joint.
The Conical Bowl Design of the Piston provides a simple
and efficient method of closing the packing unit. With the piston serving as a sealing surface against the rubber packing unit, there is no metal-to-metal wear on the sealing surface and thus longer equipment life results.
A 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.
Hydril MSP 29-1/2-500 psi
The MSP 29-1/2"-500 psi, developed for use on surface installations, is a large bore annular type diverter whose 29-1/2" bore permits hole to be drilled full bore with diverter protection. Its large bore permits the setting of large size surface casing without removing the diverter. Thus it is always ready for venting gas flows. Utilizing computerized finite element techniques, the original design of the MSP 29-1/2"-500 has been revamped to provide a unit made up of fewer parts to reduce cost. This unit may be ordered for use in standard service (temperate climates) or for use in cold environments such as the North Sea, Siberia, and Alaska where low temperature metallurgy may be required.
This MSP provides an effective means of rerouting the flow of shallow, low-pressure gas. The MSP 29-1/2"-500 can be used either as a diverter or a 500 psi annular BOP.
Only Two Moving Parts (piston and packing unit) on the
Hydril Annular Diverter mean few surfaces are subjected to wear. The Diverter is thus a safer and simpler mechanism requiring less maintenance and less downtime.
Back to Front Feedable Rubber on the Packing Unit
enables the packing unit to close and seal on almost any shape in the drillstring or close off the open bore and strip tool joints under pressure. This safety feature permits confident closure of the MSP-29-1/2"-500 at the initial indica-tion of kick without the delay of locating the tool joint.
The Conical Bowl Design of the Piston provides a simple
and efficient method of closing the packing unit. With the piston serving as a sealing surface against the rubber packing unit, there is no metal-to-metal wear on the sealing surface and thus longer equipment life results.
The MSP Diverter/BOP has been developed as a simple, reliable unit for moderate pressure drilling service, remedial work, and well servicing. It can be used on surface and subsea installations. MSP 21-1/4"-2000 operation requires both opening and closing pressure. The MSP 29-1/2"-500 requires only closing pressure. Seal off is effected by hydraulic pressure applied to the closing chamber that raises the piston, moving the packing unit radially inward into a sealing engagement. Any normal closing unit having a separate regulator valve for the annular BOP and sufficient accumulator volume can be used to operate the MSP.
STRIPPING
Cylindrical pipe sections can be rotated and standard size tool joints can be safely stripped though the closed blowout preventer packing unit. The pressure applied to the closing chamber should be low enough to allow a slight leakage of drilling fluid as the tool joint passes through the closed packing unit. The drilling fluid lubricates and cools the packing unit, reducing wear caused by rotation or stripping of pipe. Overall packing unit life is reduced when used in stripping operations.
The operation/maintenance manual for the specific MSP model provides specifications and functional guidelines.
Operation as a Diverter
When using the MSP as a Diverter during top hole drilling, the primary purpose is to divert well flows away from the rig and personnel. This application avoids shutting in the well, but instead permits routing of the flow to a safe distance on the down wind side of the rig.
In this application, the MSP is attached directly to the drive or conductor pipe. Vent lines typically are installed directly below the diverter. The lines should be sized in accordance with API standards to prevent excessive well bore back pressure buildup. This may be accomplished by using a Hydril drilling spool between the diverter and the conductor pipe.
The Hydril SXV Spool, described on page 38 of this catalog provides integral venting without external valves.
If valves are to be used in the diverter system, standards set forth in API RP64 (Recommended Practice for Diverter Systems Equipment and Operation) should be followed.
Operation as a BOP
When using the MSP as an Annular Blowout Preventer, it may be hooked up as shown (above, right). In this mode, well control operations can be conducted within the MSP's working pressure range
In either mode, pressure applied to the closing chamber raises the piston closing the packing unit to effect the seal between the packing unit and pipe. Well pressure or test pressure also acts on the MSP 21-1/4"-2000 piston below the sealed off packing unit and further increases the closing force acting on the packing unit. The MSP 29-1/2"-500 is
not wellbore assisted.
