Trendsetter Engineering and Add Energy have combined their expertise in well control engineering and equipment design to develop the relief well injection spool (RWIS).
The RWIS is designed to enable pumping of up to 200 barrels per minute of kill mud through a single relief well utilizing multiple vessels as opposed to the conventional method of multiple relief wells.
The RWIS is designed to be installed on a relief well prior to intersecting the blowout well and would be positioned between the wellhead and the blowout preventer (BOP), becoming a subsea injection manifold providing additional inlets for pumping kill mud. Each of these inlets is equipped with dual fail-safe barrier valves to provide the necessary means of pressure containment in the relief well. During the well kill operation, one or more high-pressure pumping vessels located near the relief well rig will be connected to the RWIS inlets using high pressure flexible flowlines to provide the additional mud fluid. The RWIS can be rapidly deployed by air, ground and marine freight to any region of the world.
The RWIS has already been requested for specific wells in Norway and U.S.A, and should be available to the market by the end of 2016, the company said.
