METHOD AND APPARATUS FOR MAKING A LATERAL WELL

Last updated:

Abstract:

The invention relates to an improved method for installing a dual/multiple lateral well where the overburden casing is relatively narrow. A tapered liner is employed for the first lateral. The liner has a narrow production section (109) and a larger diameter section (104) allowing a liner (116) for Lateral B to be run through it, after a window (114) has been milled. The system saves a drilling run and a liner installation run, as well as avoiding the need to set a liner hanger in Lateral A.
