Halliburton’s Completion Tools business line (NYSE: HAL) today introduced the ?VersaFlex? XtremeGrip expandable liner hanger system.? The system extends Halliburton’s liner hanger portfolio with a high-performance, expandable liner hanger that provides a compliant metal-to-metal seal with a fully bonded resilient elastomeric seal.? With a distinct design that offers enhanced bi-directional anchoring capabilities, it is designed to hang liner and seal off in temperatures up to 400 °F (204 °C) for oil and gas wells, and up to 575 °F (302 °C) for geothermal wells. The system has been tested to ISO 14310 V0 requirement on multiple sizes.
The VersaFlex XtremeGrip system is ideal for use in deepwater and offshore applications where long liners must be deployed in high temperature wells. The system is designed to minimize risks and maintain hang-weight capabilities in extreme environments.? The ability of the system to rotate and reciprocate during cementing helps improve cementing results and reduce the need for costly remediation. ?
The system has been run and set successfully in deepwater projects in Norway, Angola, Malaysia, and the Gulf of Mexico. ?In a recent Gulf of Mexico application, the VersaFlex XtremeGrip system was run through a milled window into a sidetrack to set at a depth of approximately 28,000 ft. in a 10 1/8-in. parent casing.? A liner hanger was required to reliably run production liner to permit depth, cement the liner hole annulus to isolate the production sand and to hang the liner with a competent liner-top anchor/seal package in an extremely deviated well; a feat that had not been previously performed without issue using a conventional style hanger.?
Artie Burke, vice president of Completion Tools, said, “The VersaFlex XtremeGrip system allows us to expand the operating envelop to better address operators’ current and future needs. The versatility and reliability of this system helps eliminate downtime and reduce operational time for our customers.”
Halliburton’s VersaFlex? XtremeGrip expandable liner hanger system takes the standard VersaFlex liner hanger to the next level. This high-performance, advanced metal sealing technology provides a compliant metal seal with a fully bonded resilient elastomeric seal to account for imperfections in the parent casing.
The system offers increased robustness associated with liners and liner deployment. The hanger and running tool are assembled together and form an intrinsic packoff which minimizes downhole tool components and potential leak paths while cementing. The standard tool setup offers wash- down capabilities, rotation capabilities without bearings and simultaneously allows for reciprocation of the liner. Once the cement has been placed and the tool actuates the expansion process, the hanger is set to offer bi-directional load capabilities and provide a gas-tight, liner-top seal which eliminates remedial liner-top squeeze jobs after setting.
The unique body profile of the VersaFlex XtremeGrip system utilizes engineered extrusion limiter rings to provide metal-to- metal seal and full bi-directional anchoring capability in all casing grades at elevated temperatures. Its clean-form design offers a smooth radial flow path allowing for unrestricted bypass area, which assist in reducing equivalent circulating densities (ECDs) during all phases of the operation.
