State of in situ stresses determined by hydraulic fracturing at the Hanford Site

Creators

Description

This report summarizes the hydraulic fracturing stress determinations conducted during the period 1981 through 1983 by the Basalt Waste Isolation Project. These tests were conducted in boreholes DC-12, RRL-2, RRL-6, and DC-4 to estimate the state of stress in and about the candidate repository horizons within the Hanford Site. Three of these boreholes (RRL-2, RRL-6, and DC-4) are within the reference repository location. Test procedures, test data, analysis methodology, and calculated in situ stresses in the Cohassett, Grande Ronde 7, Umtanum, and McCoy Canyon basalt flows are presented, along with a brief discussion of seismic activity in the Pasco Basin, core disking, and borehole spalling observed in Hanford Site boreholes
