ABSTRACT:
A well completion system and method including a landing adapter which can be interlocked with a landing ring. A split ring is retained within a groove in the landing adapter which operates to lock the landing adapter with the landing ring. The groove into which the shear ring is positioned has two effective diameters. A first diameter allows the shear ring to compress and pass within the landing ring. The second diameter prevents extraction without shearing of the ring. A by-pass tool is positioned with a liner assembly 14 having a landing adapter. The by-pass tool includes a valve sleeve having a first position allowing flow down the center bore into a stinger extending to a wash-in shoe. Once the liner assembly has been washed in, the valve sleeve assumes a second, open position. Gravel packing may then occur through the central bore with return through a by-pass passage through the tool. Cleaning of the liner and tool can also occur through reverse flow to the gravel packed area.
