Geology of Carbonate Reservoirs

The geology of carbonate reservoirs involves rocks like limestone and dolomite, formed mainly from marine organisms’ shells and skeletons that accumulated over millions of years. These rocks often develop interconnected spaces called porosity, which hold oil or gas. The structure and history of these rocks—such as folding, faulting, or dissolution—affect how we can extract hydrocarbons. Understanding their mineral composition, layering, and formation processes helps geologists locate and efficiently develop these reservoirs, which are a major source of global oil and natural gas supplies.
