Tar sands and heavy oil reservoir evaluation using geophysical well logs
Geophysical well logs and associated interpretive techniques provide in-situ evaluation of several important reservoir parameters in tar sands and heavy oil reservoirs. Information such as lithology variations, reservoir shaliness and cation exchange capacity estimates, silt and fines content, porosity, hydrocarbon saturation and the elastic rock constants can be derived from the response of various well logging devices which can be run in open or cased wellbores. Applicable well logging instrumentation includes resistivity and conductivity-types (induction, dielectric, etc.), gamma ray and spectral gamma ray sondes, acoustic, density, neutron, and pulsed neutron devices. These concepts are illustrated in several field case examples.
