The appearance of carbonate rocks in seismic data contains information about their original depositional environments, lithofacies, diagenesis, and source rock and reservoir potential. Carbonate seismic facies can be interpreted through analysis of the configuration, amplitude, frequency, and continuity of the seismic reflections. The geometries of the reflection configurations are the most varied aspect of seismic data, including parallel, prograding, mounded, draped, onlap, and onlap fill. Each geometry suggests different depositional processes that can occur in different depositional environments. Amplitude and frequency can also be diagnostic of carbonate rocks; a lack of continuity is often characteristic of carbonate buildups. Carbonate platforms, platform margin, slope environments, and basinal deposits have characteristic combinations of seismic facies that aid in their recognition and in the evaluation of their hydrocarbon potential.
