摘要: An isolation assembly for use with coiled tubing is described. The has a check valve providing selective fluid communication through from the tubing, assembly, and into downhole tool, such straddle packer. includes shuttle moveable within housing, plurality of ports to selectively provide below valve, ports, annulus, thus allowing surface-controlled equalization equipment. Also described bottom hole including assembly. improved method fracing formation improving life safety operation, reducing time perform given operation.
