A petroleum reservoir was simulated in the laboratory, undergoing overburden pressure of 10,000 psi and fluid pressure of 4,500 psi. Variations in these pressures were achieved by exterior controls. A recording of oil production versus pressure drop was made using mercury-pump volume changes. Simultaneously with production, acoustic measurements were made with transducers placed in the producing reservoir. From, the measured data on fluid production, the pore compressibility was calculated. Macrosopic compression and microscopic compaction could be observed during production in the reservoir. This experiment was conducted to check equations developed by Overton and Norman for pore volume compressibility from acoustic log measurements. The equations and reservoir measurements agreed, with variation of no more than 10%. It is suggested that c be calculated from acoustic log data for deep reservoirs, using the following equation: P
