Carbonates account for about 40% of global hydrocarbon production and more than 70% of domestic hydrocarbon production in India. Carbonates are typically different from sandstones due to their origin, depositional environment and subsequent dia-genesis. It has been speculated that globally, the carbonate reservoirs contain about 60% of the hydrocarbons in place with a total life span of about 80 years and hence for obvious reasons the exploration of carbonate reservoirs is of vital importance. However, it is easier said than done. This is primarily due to the complexities posed by the carbonate reservoirs in the form of the multi porosity system, owing to diagenesis, which gives heterogeneity to the entire reservoir making it a difficult task to predict the various parameters required for the successful exploration and subsequent recovery of oil and gas.
