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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
