Abstract
A subterranean well system and a process for drilling and completing such a system from a first subterranean well bore which extends to the surface of the earth. A second well bore may be drilled from the first well bore and a first tubular of a multiple well drilling template can be positioned within the first well bore while a second tubular of the template can be positioned within both the first and second well bores. Additionally, a third well bore can be drilled from the first well bore and the first tubular can be further positioned therein. The first and second well bores can penetrate subterranean formation(s) or additional well bore(s) can be drilled from the first, second and/or third well bores so as to penetrate subterranean formations. A second multiple well drilling template may be utilized to drill such additional well bore(s) from the second or third well bores. Fluid is produced from subterranean formation(s) to the surface via said first, second, third and/or additional well bores and/or through production casing and/or tubing positioned therein.
