摘要

A template and process for drilling and completing multiple wells in a subterranean formation. A template having a plurality of axially extending, divergent bores therethrough is secured to surface or intermediate casing and a like plurality of subterranean wells are drilled through the bores and into the subterranean formation. Each well is separately cased to the well head at the surface and separate production tubing is inserted into each well. Thus, remedial operations can be carried out in one well or fluid injected into a subterranean formation via one well while fluid, such as hydrocarbons, are simultaneously produced from a subterranean formation via the other well(s).
