OSTI ID:4116137

Rio Blanco Well RB-U-4 is a gas reservoir evaluation well drilled to a depth of 7,000 feet in the Piceance Basin of northwestern Colorado. This well is a part of Project Rio Blanco whose goal is to demonstrate the potential for commercial development of low-permeability gas reservoirs by nuclear explosive stimulation. Well RB-U-4 was drilled approximately 624 feet from the surface location of the nuclear emplacement well and outside the fractured zone produced by the explosives to obtain information on the undisturbed gas reservoir. The drilling, completion, and initial testing of RB-U-4 including drilling reports, drill bit records, logging records, hole deviation data, casing and cementing descriptions, hydraulic fracturing procedures, flow testing information, and current surface and downhole equipment configuration are described.
