The Value of Core: Petrographic and Petrophysical Integration. A Case Study from the onshore Southern Mozambique Basin

Abstract

SummaryThe value of conventional core for the calibration of wireline logs and reservoir characterisation cannot be underestimated. A case study which shows how petrographic data and data from Routine and Special Core Analysis (RCAL and SCAL) can be integrated with the wireline log data to better understand the nature of the pore types and systems and the controls on reservoir quality is presented. The methodology used to capture the proportion of the multiple pore types and the impact on other petrophysical properties (such as water saturation estimation) is also explored.
