Abstract
Summary
The presence of clay minerals or shale in porous formations presents problems from the interpretation of wireline logs. This mainly affects the porosity and water saturation quantification of the reservoir which result into gross effect in the calculation of hydrocarbon in place (STOOIP). Most of the sand reservoirs show some degree of shaliness. It has therefore become vital to determine the effect of shale content in most of the clastic reservoirs. This project is dedicated in describing the relationship between shale content and the porosity of clastic reservoirs and derive any trend between the two parameters using wireline logging data from Mkuki-1 well, offshore Tanzania.
