Recent Advancements in Reservoir Description Techniques

Lori Higgins, Anwar Ghauri, A. Sinha

Advanced and integrated formation evaluation techniques are vital in describing lithologically and structurally complex reservoirs. A databank is created by integrating geological, geophysical, and well (log, core, and production) data. Well-log normalization is a key element utilized for accurate reservoir description, which is achieved via cross-plots, histograms, and maps illustrating the distribution of normalization connection for the field under study.

Important reservoir parameters are computed using advanced interpretation techniques and results are compared to core-derived values. Accurate core or production data enable the log responses to be calibrated for computing porosity, permeability, and clay typing. In addition, a reservoir parameter summary program computes average and cumulative values, which are used to generate reservoir isopach maps.
