Comparative Study of Rock Strength and Petrophysical Properties Derived from Core and Log Data

Abstract

This study presents a uniaxial compressive strength property and petrophysical data obtained from log and core derived data of well R4 of a field in the Niger Delta region of Nigeria a continent in Africa. Petrophysical properties is referred to as the physical and chemical properties of rocks that are related to pore space and distributions of fluid especially as they apply to detection and evaluation of hydrocarbon bearing layers. This is one of the key properties in estimating the quantity of hydrocarbon original in place and without which no informed decision will be made on the field’s development. As a result of the sensitivity of the petrophysical parameters, there is need to compare value of these properties from other sources of information for a quality control and assurance of the data used for analysis. Results showed that the formation is heterogeneous. This will help the management in decision making either to develop the field, where to place wells and in simulating full field study to predict future reservoir performance and optimum strategy to economically recover the subsurface hydrocarbon volume.
