ABSTRACT:
An apparatus and process are provided for drilling and completing multiple subterranean wells from a template which is secured within a cased well bore extending to the surface. An orienting cam having a bore therethrough is positioned above the template such that the bore through the orienting cam is automatically aligned with one of at least two bores through the template. Fluid tight seals are provided between the orienting cam and the casing and between the orienting cam and one of the at least two bores through the template. Thereafter, a drill string including a drill bit is lowered from the surface of the earth through the casing, the bore through the orienting cam and the one bore through said template to drill a first subterranean well bore. Drilling fluid and cuttings resulting from drilling a subterranean formation are circulated back to the surface via first subterranean well bore, one of the at least two bores through the template and the bore through the orienting cam and through the casing such that the drilling mud contacts the internal wall of the casing. The orienting cam is repositioned above the template such that the bore through the orienting cam is aligned with another of the at least two bores through the template. Thereafter, a second subterranean well bore is drilled via another of the bores through the template in a manner similar to that described for the first well bore.
