Well control at surface.
The Pump Out Sub is used to circulate fluid from the drill string after the DST has been completed and the drill string is ready to be removed.
Houses four down hole gauges.
The Hydraulic Valve is a down hole valve used in opening and closing the flow from the test zone.
The Sampler catches a sample of produced fluid and retains the sample at the down hole pressure of the interval at the instant that the hydraulic valve is closed.
The Squeeze Tool is a check valve that opens to balance tubing to annular pressure when the tubing pressure exceeds annular pressure.
The Extension Joint is used to allow free travel of the workstring. This allows operators to get a good indication of hole drag in deviated holes.
The Hydraulic Jars allow jarring of the test string to aid in the freeing of downhole tools.
The Safety Joint provides a means for releasing from a set of tools that are stuck in the hole.
The Conventional Packer contains a telescoping mechanism to compress rubber elements against the formation when weight is applied.
The Gauge Carrier has been designed as a single body type carrier capable of housing four electronic memory pressure/temperature gauges capable of monitoring either tubing or annulus pressures.
