Oil and Gas Separator

Oil and Gas Separator

PDF
Oil and Gas Separator

The Oil and Gas Separator tool is designed to help separate foam gas from heavy and conventional oil in horizontal applications and laid out directional wellbores. The unique feature of the Oil and Gas Separator is its ability to allow gas to flow up casing annular and not interfere with the pump production. The unique field proven design maintains production intake on the horizontal well bottom while insuring minimal gas intake. It allows the gas to rise to the top of the liner, flow along the liner top, and migrate to the surface, while the higher density oil lying on bottom is able to flow to the production intake on the Oil and Gas Separator. The tool is run on the bottom of the pump or tubing and landed as per pump intake. No functioning is needed to set or release. Advantages • Simplicity of design allowing minimal chance of functional failure • Minimal servicing • The unique continuous bottom intake is always maintained even when rotating tubing string. • Large intake area for maximum flow intake • Ease of running Bridge Plugs & Retainers

On-Off Connector Skirt

On-Off Connector Skirt The On-Off Connector Skirt is compact, reliable, fully sealing, J-type tubing disconnect device that automatically engages and releases with a small amount of left-hand rotation. It is designed for use with right-hand release locking type double-grip retrievable packers, or with a locking type right-hand release seal unit in a permanent packer. The unit is composed of two main compo- nents, the mandrel, which is attached directly to the packer mandrel, and the overshot, which is attached directly to the tubing string. A wireline profile is commonly integrated into the mandrel portion of the tool which would allow a blanking plug to be installed in the mandrel and would al- low the packer to act as a temporary bridge plug. The On-Off Connector Skirt design incorporates a molded high pressure sealing system that ensures reliable sealing even with repeated disconnections with differential pressure.

Key features
  • Disconnects with 1/3 turn left-hand rotation at the tool.
  • Molded seal system with full metal backup maintains its integrity even
  • Suitable for use with the Limit 75 Mechanical Packer or most similar
  • The On-Off Mandrel must be used for wireline setting the Limit 75 Mechanical Packer.

Tubing Drain

The Tubing Drain provides a single use, pressure actuated system for providing a reliable and economical method of opening up communication between the tubing and annulus. It is designed primarily for use on rod pumped wells to provide a reliable method of draining the tubing in cases where the pump and/or valve cannot be retrieved with the rod string by pressuring up the tubing against the pump. The drain can also serve as an emergency method of killing the formation. The Tubing Drain is activated by differential pressure in favor of the tubing. Removing or adding shear screws can adjust the trip pressure. Once activated, the Tubing Drain cannot be closed. Note: Differential pressures below are based on actual test results. No less than two shear screws spaced at 180 degrees should be used. Screws should be spaced evenly around the circumfer- ence. Shear value may possibly vary by 10%. Note: The 2-3/8 and 2-7/8 EUE size tubing drains use the 000-151 shear screw. The 3-1/2 uses the 000-008 shear screw Tubing Anchors Tubing Size Maximum O.D.

Tubing Pump-Out Plug

The Tubing Pump-Out Plug provides a single-use, pressure actuated method of providing a safe, reliable, and economical method of temporarily sealing the tubing ID during running of the tubing string. The pump-out plug is designed to be run on the bottom of the tubing string and to be ex- pended when required by pressuring up the tubing. The expended plug portion that remains in the well is manufactured from materials, which can be drilled up with a standard rock bit. The Tubing Pump-Out Plug trip pressure may be adjusted by removing or adding shear screws. Retrievable Packers & Accessories Tubing O.D. Max.
