Electronic Setting Tool (EST)
Product Description
Interwell’s Electronic Setting Tool (EST) is a non-pre-pressurized, non-pyrotechnic setting tool for the installation of downhole products such as Bridge Plugs, Packers, Gauge Hangers and Straddles. It is field resettable and is the shortest setting tool on the market, capable of logging the parameters required to create a setting profile for quality assurance of the set product and health monitoring of the EST.
The EST converts its internal power into a downward axial force to mechanically set the Interwell or third party product. Processes within the tool are controlled and logged by an Electronics Module, activated for use on Slickline (timer based) or E-Line. After the product setting has been completed, the EST goes through an automatic shutdown sequence and at full stroke the oil is recirculated, preventing pressure build-up. Some of the logged parameters include temperature, internal pressure, battery/motor voltage and battery/motor current. Options for external pressure logging and Bluetooth communication are also available.
Under development:
• Data communication over E-Line
Product Features
• Bluetooth
• Field Resettable
• Large output force
• Accurate time delay mechanism
• Debris tolerant, fully self-contained
• Non-pre-pressurized, non-pyrotechnic
• Does not rely on well pressure for operation
• Setting force applied in a controlled manner
• Able to be jarred free from the plug if necessary
• The shortest setting tool available on the market
• Well pressure measurement during setting process (optional)
Product Benefits:
Now Bluetooth compatible. Wireless communication with the EST is now possible before and after run in hole: check tool status, set and start timer, download log, all can be performed using Bluetooth. Facilitates wireless communication (Wi- Fi, 3G, 4G) with IO Centers for monitor and control. Extensive run record, field resettable, reliable, high output force, long stroke, logging.
Hydrostatic Setting Tool (HST)
Product Description
The Hydrostatic Setting Tool (HST) provides the industry with a reliable, non-pyrotechnic, non-pre-pressurized (when used in hydrostatic configuration) setting device, used for the installation of downhole products such as Bridge Plugs, Packers, Gauge Hangers and Straddles.
The setting tool converts the hydrostatic well pressure into an axial force. The short overall length of the HST has been achieved by incorporating a highly efficient pressure multiplying piston area. This combined with a unique regulating device, allows the hydrostatic well pressure to be boosted within the tool, which in turn provides the high axial force.
Product Application
The HST has an extensive run record on both Slickline and E-Line, and can simply and quickly be converted for either mode of deployment on the rig site. In addition, the HST can be adapted for coil tubing and drill pipe applications as required. When run on Slickline, an external plunger switch allows the timer to be started just before the tool string is picked up and the lower end of the setting tool will make up to industry standard wireline adapter kits. An option for a Pressure Module to be fitted above the HST is available, for applications where there is insufficient hydrostatic well pressure or high levels of debris in the well.
Product Features
• Non-pyrotechnic
•Non-pre-pressurized (hydrostatic configuration)
•Debris tolerant (Pressure Module configuration)
•Large output force
•Extensive run record
•Accurate time delay mechanism
• Reduces risks associated with Wireline mechanical manipulation
Product Benefits:
The HST is available in standard, long stroke and HPHT versions. Always non-pyrotechnic and non-pre-pressurized when used in hydrostatic configuration.
ELECTRONIC SETTING TOOL (EST) SUCCESS
After an extensive development and testing period, the EST was approved for use by Statoil. The EST was run for the first time in the North Sea, successfully setting an Interwell 550-700 ME Retrievable Bridge Plug for Statoil, in the Statfjord field. The EST has options to log the setting pressure which can be converted to the setting force, as well as temperature and electrical parameters. The EST’s log was downloaded after the run and all parameters were in line with expectations.
