Drilling Fluid Recovery When Drilling Under An Obstacle Or Water Body
US Patent:
2012018, Jul 26, 2012
Filed:
Jul 28, 2011
Appl. No.:
13/193354
Inventors:
Ronald G. Halderman - Billings MT, US
Karl D. Quackenbush - Blanchard MI, US
Karl D. Quackenbush - Blanchard MI, US
International Classification:
E21B 21/06, E21B 17/10
US Classification:
175 66, 1753255
Abstract:
A system for recovering drilling mud in drilling an underground arcuate path around at least a portion of an obstacle has a conductor casing, a drill pipe surrounded by the conductor casing for at least a portion of an axial length of the drill pipe, a flow line connected to the conductor casing at a downhole position, and a pump coupled to the flow line placed at another downhole position. A volume of drilling mud within the underground arcuate path is pumped from the underground arcuate path to the surface and recovered for recirculation.

International Classification:
G06F 17/50, G06F 19/00, G01V 9/00, E21B 49/00, G06Q 99/00
US Classification:
703 1, 702 6, 702 11, 175 50, 705400
Abstract:
A system and method for designing and constructing an optimized underground crossing through the earth is provided. The underground crossing allows one or more delivery line to pass through the earth. The method involves forming an investigation bore path along a preliminary path of the underground crossing and collecting geological data along the investigation bore path. The method involves determining a selected bore path for the underground crossing and finalizing a design for the construction of the underground crossing. The finalized design is based upon the collected geological data. The method involves obtaining one or more permits for the underground crossing based on the finalized design.
