Abstract

LRLC pay zone is generally recognized, due to low resistivity and low contrast reading from the well logs. This is associated with a variety of factors such as micro-porosity, very low water salinity of formation water, rock’s mineral content such as conductive minerals and very thin inter-bedding of sand and shale. Due to limitation performance of conventional logging tool, many potential productive zones commonly with high irreducible water saturation are by passed and quantification of hydrocarbon volumes is under estimated. The main objective of this project is to propose a workflow diagram for LRLC formations evaluation specifically on clastic reservoirs. This is done by first trying to understand the depositional environment of LRLC formation; then later to the phenomenon involved in LRLC that is in other words the causes and relatively how it can affect the performances of logging tools. Some researchers have come up with a few approaches in order to solve the problems in LRLC formation. Their techniques are mostly using the advanced tools such as Nuclear Magnetic Resonance (NMR), Multi-component induction tool (3DexTM) and electrical borehole imaging (EBI). Main indicator in hydrocarbon determination is to compute the water saturation (Sw). Therefore, many published works carried out the special core analysis (SCAL) to determine the water saturation from this LRLC formation. The workflow can at least help petrophysicists to facilitate critical decision making for LRLC formation evaluation in a timely manner.
