Reservoir deformations associated with large pore pressure drawdowns can play a significant role in the production performance of deep oil and brine reservoirs. In order to evaluate these effects, laboratory measurements were performed at simulated in situ conditions on core from geopressured production intervals from the T-FandS/DOE Gladys McCall No. 1 Well, Cameron Parish, La. The test conditions ranged ca 15,000 psi confining pressure, 4000 psi vertical deviatoric stress, and 13,000 psi pore pressure at temperatures of 300 F. Reservoir drawdown was simulated by reducing the pore pressure at constant lateral strain and overburden stress. Elastic moduli, failure strengths, and creep rates were determined from the tests. A number of permeability measurements also were performed. The effect of reservoir drawdown on the production potential was assessed by combining these measurements with a simple one-dimensional liquid phase reservoir model.
