LLL Gas Stimulation Program. Quarterly progress report, January-March 1979

OSTI ID:5914121
This report summarizes the reseach and accomplishments of the LLL Gas Stimulation Program during the second quarter of FY 1979. Two-dimensional dynamic models were used to analyze some aspects of dynamic fracture propagation near bonded interfaces. Theoretical models were also used to analyze aspects of a blunting process that occurs when a pressurized fracture contacts another fracture that lies at various angles to the created fracture. Friction coefficient measurements for Indiana limestone show 0.51 as an indicated mean value of the static frictional coefficient. Effects of viscosity of the fracturing fluid were experimentally determined under various principal stress states in a polyaxial stress cell. Some intial log analyses and comparisons with core for a well in the Piceance basin were also completed.
