Modular VACS System Cleaned Wellbore and Retrieved Plugs in One Trip
Delivered advanced wellbore cleanup in deepwater wellAn operator in deepwater Gulf of Mexico had planned a triple-stacked frac-pack completion in the intervals perforated with length of 136 ft, 359 ft, and 456 ft (41.4 m, 109.4 m, and 139 m). The operator needed to clean the perforation burrs, remove the debris on top of the packer plugs, and retrieve packer plugs for the top and middle intervals with minimum operation cost and time.
Baker Hughes designed a vector annular cleaning system (VACS™) technology that combined a variety of fishing and wellbore cleanup tools to meet the operator’s needs in one trip. The modular VACS system allowed for faster make-up and debris collection on the rig floor, and improved debris capture capability with two separate debris chambers. The full function valve (FFV) gave the operator the ability to open communication to the annulus after cleaning up the gun debris with the VACS system to circulate bottom up at high rate. The FFV also provided the ability to shift back closed, giving the operator the option to reactivate the VACS tool if needed.
