The Shut In Valve is used for compression set tests and is designed to take up to two flow periods and two shut in periods. It is run immediately above the Hydraulic Valve. It operates by right hand rotation of the drill pipe.
It is run in the open position. When...
|
The Full Bore Rotating Control Head is a modular 10,000psi or 15,000psi flow head which can be configured with up to 4 valves and 3 flow paths. The solid one-piece center mandrel allows torque to be transferred to the tubing/drill pipe by rotating from above (Top...
|
The Squeeze Tool is a check valve that opens to balance tubing to annular pressure when the tubing pressure exceeds annular pressure. This prevents supercharging of the formation in the interval while setting packers or opening the downhole hydraulic valve.
The...
|
The Safety Joint provides a means for releasing from a set of tools that are stuck in the hole.
The Safety Joint is released with left hand rotation with about 20% of the torque required to break other tool joints in the string. The Safety Joint requires 5 ½ to 6...
|
The Conventional Packer contains a telescoping mechanism to compress rubber elements against the formation when weight is applied.
When weight is applied to the packer section, a mandrel telescopes into the Travel Housing, compressing the Packer Element. The weight...
|
The Ratchet-Set Compression Packer (RSCP) is an open hole packer with a telescoping locking mechanism, which locks the packer in the set position. Reliable setting and releasing is achieved with a completely internal locking mechanism. There are no slips or dies in...
|
The Hydraulic Jars allow jarring of the test string to aid in the freeing of downhole tools. The jar provides a temporary resistance that allows the drill pipe to be stretched. When the resistance is release, the drill pipe contracts to deliver the impact and freeing...
