... amount of void space that is measured in the rock at the lab. Standard practice calls for treating this void space as previously occupied by oil that has volatized during coring operations, transport, and core testing. Therefore, estimates of hydrocarbon filled porosity are made using the volume of oil...

NMR logs were primarily used to assess the porosity and permeability variations of the oolitic reservoirs with high resolution, highlighting the intervals with the highest fluid movability through the thin layers. NMR measurements were also applied to describe the pore system...

... the low dynamic range at porosity near 12 p.u., has proven to be challenging in the low-porosity, gas rock. A new measurement from the third detector from a multi-detector pulsed-neutron tool (MDPNT) is proposed to provide a better estimation of the gas saturation in a low-porosity reservoir. Two...
