QUANTIFYING PORE TYPES AND MICROPOROSITY EFFECTS BASED ON ELASTIC PROPERTIES ANALYSIS OF OFFSHORE SARAWAK CARBONATE RESERVOIR

Velocity and density as basis of modulus components on any rock formations are effected by the rock matrix, the pore geometry and also the fluids saturated in the formations. In carbonate formations, complex porosity dominates comprises of fractures, vugs, and moldic porosity which are the main iden...
