Halliburton Co. released its Dash Large Bore Subsea Safety System providing full electrohydraulic control of well safety and intervention functions that has easier testing and assembly, faster activation, and ease of configuration to projects, the company said in a February press release.
Deepwater operators doing completions and interventions will have improved critical control of the subsea safety system, tubing hanger and deepwater subsea field developments.
Halliburton said it collaborated with customers to design the Dash Large Bore, which can isolate the lower landing string in six seconds or less, disconnect from the lower landing string in ten seconds or less, and provide downhole data.
The two larger bore sizes, 6-3/8 inch and 7-3/8 inch, in addition to the existing Dash 3-inch system, broaden the use of Halliburton’s electrohydraulic subsea safety systems.
Halliburton said that Noble Energy Inc. (NYSE: NBL) used the Dash Large Bore recently during plug and abandonment operations in the U.S. Gulf of Mexico, where Dash Large Bore was the primary well control barrier and BOP, reducing rig time by several days.
