Filed:

Mar 12, 2010

Appl. No.:

12/723021

Inventors:

Dean Lee - Katy TX, US
Richard Thomas Hay - Spring TX, US
Nesto Humberto Gil - Edmonton, CA
Kyler Tebbutt - Edmonton, CA
Rodney A. Schnell - Calgary, CA
Joe E. Hess - Wasilla AK, US

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

E21B 7/04

US Classification:

175 61, 175 62, 166380, 1661175

Abstract:

A borehole network including first and second end surface locations and at least one intermediate surface location interconnected by a subterranean path, and a method for connecting a subterranean path between a first borehole including a directional section and a second borehole including a directional section. A directional drilling component is drilled in at least one of the directional sections to obtain a required proximity between the first and second boreholes. An intersecting component is drilled, utilizing magnetic ranging techniques, from one directional section to provide a borehole intersection between the first and second boreholes, thereby connecting the subterranean path.
