Recorder Hanger

The Recorder Hanger is used to hang a pressure recorder inside a length of spacing or drill pipe (bomb well).

The Single Recorder Hanger can be run at any location within the test string except between the Infl ate Pump and the bottom packer (on an infl ate test).

Details

1003
Pump Out Sub

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.

The Pump Out Sub consists of a short sub with one or more hollow pins screwed into the sides. These pins project into the sub bore during the course of a test.

Details

1002
Hydraulic Valve

The Hydraulic Valve is a down hole valve used in opening and closing the flow from the test zone. The tool gives positive surface indications of opening: a sudden small movement of the drill pipe, combined with a slight reduction in drill pipe weight.

Details

1004
Sampler

The Sampler catches a sample of produced fluid and retains the sample at the downhole pressure of the interval at the instant that the hydraulic valve is closed. The valves of the Sampler are opened and closed by the movement of a mandrel extending from the hydraulic valve.

Details

2004
Squeeze Tool

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.

Details

1006
Extension Joint

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 Extension Joint also allows free pipe movement before the Hydraulic Valve is operated.

Details

2007
Hydraulic Jars

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 force.

Details

2005
Safety Joint

The Safety Joint provides a means for releasing from a set of tools that are stuck in the hole.

Details

3130
Retrievable Casing Packer

The Retrievable Casing Packer permits unrestricted flow and passage of full gauge wireline tools and accessories with an unrestricted ID, making it ideal for zone isolation, injection, testing, perforating, and production. Retrievable Casing Packer can be set for testing in tension, compression or neutral.

Details

1020
Dual Recorder Carrier

The Dual Recorder Carrier is designed to be run in the test interval and holds two pressure recorders. Recorders are loaded through loosely fitted doors bolted to the sides of the carrier.

Details

4000
Pressure Gauges

Measure & record Downhole Pressure & Temperature in geothermal wells.

Details

2008
Bottom Hole Choke

The Bottom Hole Choke is a short sub that can be located to restrict flow downhole through standard fixed chokes.
