Hydraulic borehole pressure cells: equipment, technique, and theories.
Denver, CO: U.S. Department of the Interior, Bureau of Mines, IC 9294, 1991 Jan; :1-26
This U.S. Bureau of Mines report describes the use of Bureau- developed flat and cylindrical hydraulic borehole pressure cells. A brief description of the fabrication, installation, and pressurizing equipment is given, and pressurizing procedures are discussed. Theories available on evaluation of data from the flat and cylindrical pressure cells and examples of data analysis and stress evaluation are also presented.
