Abstract

Well Planning and placement in carbonate reservoirs is always challenging due to the inherent nature of carbonates. Carbonate reservoirs can be extremely heterogeneous in pore space and permeability. Karstification in carbonate cause additional heterogeneity. Hydrocarbon production from such heterogeneous formation is often influenced by the presence of faults & fractures. Knowledge of the distribution of the karst bodies, faults and fractures in carbonates is helpful for well planning and placement in a mature field. In many fields, existing seismic data is found to be inadequate to map karst bodies requiring acquisition of new high resolution seismic data and new processing workflows and interpretation techniques.
