For Reference Only At Bureau Libraries :26 pages
Pilot hole "x" was drilled to test the formations through which the ventilation shaft for the proposed federal Bureau of Mines demonstration oil shale mine will be drilled. Five permeability tests were performed at various stratigraphic levels within this hole. The test method used was that of pumping fluids out of the hole for 3 hours, using the airlift method, followed by a 3-hour period where the recharge was observed. Transmissivity and permeability results were determined from these test data. The test procedure is described and supporting data for the hydrologic tests are provided.
