Okemos Engineering’s 1″ and 1.1/2″ Wireline Retrievable Dummy Valves are manufactured to meet the requirements of API 11V1 specifications. They are installed in side pocket mandrels as a non-equalizing isolation tool. The Wireline Retrievable Dummy Valve is an isolation tool designed to blank communication between the tubing and casing. This valve can be used to blank off a side pocket mandrel.

The Dummy Valve is available in either Stainless Steel or Nickel alloys for corrosion resistance in wells with high concentrations of H2S and CO2. Packing for the valve is available for standard service or special service to suit individual well conditions.

The distance between the packing stacks is maximized to fully protect the mandrel pocket seal bores from produced fluids until they are removed from the completion. The simple design of the dummy valve allows for easy replacement of the packing and for rapid low-cost repair of its components. The rugged, solid construction and quality metals provide for a long service life.

The Dummy Valve uses BK-2 Latch. It has two sets of packing which straddle and pack off the casing in a side pocket mandrel. Communication between the tubing and casing is positively blanked off until the Dummy Valve is removed from the pocket by standard wireline procedures

FEATURES & BENEFITS:

• Standard construction is stainless steel, with monel or other premium materials optional.
• Wireline retrievable by standard methods.
• Use standard top latches.
• Temperature rating of 250°F (121°C) (Standard Service)
• Maximized packing separation for complete seal bore protection in the mandrel pocket.
• Standard Neoprene packing with other materials available.
• Compatible with other manufacturers side pocket mandrels.

APPLICATIONS:

•  To blank off the tubing while completing the well / prior to pressurizing the tubing to set a hydraulic set packer.
• To blank off the tubing for production until gas lift valves are required.
• To allow the tubing to be pressurized in various situations.
• To isolate the tubing and casing during single alternative production sequences.
• To isolate tubing and casing flow for test purposes during multi-point water flood or gas injection modes.
• Allow for production prior to installation of the Gas Lift Valves
• Isolate tubing from casing annulus during remedial work such as acidizing or fracturing.
