Abstract

Petrophysical volumes are one of the key inputs for any physical Rock Physics modelling workflow. Rock Physics cross plot trends play an important role in Lithology and fluid indentification/ discrimination. Realistic estimations of these petrophysical volumes (mineral volumes, porosity and fluid saturations) become quite important in complex lithology formations, e.g., Panna formation, in Bombay Offshore field in India, since these petrophysical volumes drive the Rock Physics trends for each lithology. Bombay Offshore field, in India, comprises of three producing formations, each with different relative percentages of calcite, quartz, dolomite and clay. Since, each mineral has a different elastic property its relative percentage in a rock affects the elastic response differently.
