... through placement of 575 ft of cement plug in the 3 1/2-in. tubing from 6,511 to 5936 ft MD. A rigless through-tubing balanced cement plug concept for cement packer installation and reperforations was deployed to access behind pipe oil reserves in a high-angle (69 to 72º) deviated well, Offshore Niger...
