Abstract: A hydraulic method for opening and closing a ram and operating a wedge lock and unlock mechanism using only an open port and a close port. To close the rams and lock the rams in a closed position, hydraulic fluid is directed to the close port where the rams close and then are locked in the closed position. To open the rams, hydraulic fluid is direct to the open port whereupon the wedge locks are unlocked. Afterward the wedge locks are unlocked, hydraulic fluid is utilized to open the rams.

Abstract: A weldless adapter is mountable to a conductor casing for pressure testing seals or initial drilling at a well site. Slips engage the conductor casing to latch the weldless adapter onto the casing. Pressure injection ports are utilized to activate two seal rings against the conductor casing using positive sealing. A test port is utilized to test the seals of the two seal rings. The slips are activated by three sets of bolts.

Abstract: A high power, compact BOP booster and bonnet assembly for rams and, more particularly. Solid ram change pistons or bonnet pistons are in bonnet end caps that are hydraulically controlled. The bonnet pistons move from either an open position or a closed position to urge the booster and bonnet assembly replacement and installing the BOP shear members.

Abstract: Non-sealing casing shear rams are utilized in a blow out preventer (“BOP”) for shearing or cutting casing, but do not seal. The BOP with non-sealing casing shear rams with V-shaped blades has the shearing capabilities of a larger shear ram BOP while utilizing a smaller sized BOP to reduce the need for additional time, expense, and equipment. The non-sealing casing shear ram BOP may be used for drilling operations and during production without the need for swapping a larger shear ram BOP used for drilling to a smaller shear ram BOP for operations. The V-shape blade and back rake angle of the non-sealing casing shear ram blades produce the shearing force of the larger BOP in a smaller sized BOP.

Abstract: A machined internal cavity for a forged block of a workover BOP. The ram internal cavity has a bore along an inner cavity wall into which a ram guide is insertable. The ram cavity has a flat upper sealing surface that is engageable with a seal on a ram and a raised landing surface to guide the ram to engage the seal with the flat upper sealing surface. Mud slots are machined on the lower surface of the machined internal cavity profile. The ram has a side entry access point into which the rams are installed or accessed within the machined internal cavity.

Abstract: An annular preventer blowout preventer (BOP) that can seal off a wellbore for controlling and monitoring oil and gas wells. The BOP is a latch type annular preventer with a body, a inner, a piston, and a rubber packing element. The preventer seals around drill pipe and in some instances against an open well bore. A plurality of latches and inner screws secure the lid to the body and further prevent rotation.

Abstract: A BOP booster assembly is provided for use with BOPs that utilize hydraulic actuators mounted in BOP end caps to open the BOP for replacement of the shearing members. The booster assembly has three main components comprising a booster housing, piston, and end plate. An extension in the booster housing is sufficiently long to position the booster hydraulic cylinder axially outside of the ends of the bonnet end caps of the BOP with respect to the wellbore. The booster piston is equal in diameter or larger than the operating piston of the BOP. The operating pistons and booster pistons move simultaneously, in sync, and the same distance for closing and cutting. In one embodiment, an internal hydraulic line is provided in the booster cylinder wall.
