Abstract

The study of seismic reservoir properties is an important aspect of reservoir characterization and management using seismic technology because it directly links seismology to rock properties. Results of such a study, both experimental and theoretical, provide a fundamental understanding of seismic responses to reservoir properties and their dynamic changes so that seismic attributes can be converted to reservoir parameters. Unlike siliceous clastic reservoir rocks, carbonate rocks tend to have complicated pore systems, such as vugs, molds, channels, and fractures. Different types of pores have different compressibilities so they affect seismic wave velocities differently. Furthermore, pore types also control seismic responses to pore fluid changes in the reservoir. Besides pore types, factors that influence seismic wave velocities in carbonate rocks include mineralogy, porosity, pore fluid type and saturation, and reservoir parameters such as pressure and temperature. Studies of seismic properties of carbonate rocks play an important role in seismic reservoir characterization and monitoring. Recent laboratory results show that carbonate pore type and pore fluid compressibility contrast are the two most important factors in the feasibility of seismic monitoring of fluid movement in carbonate reservoirs.
