Well Logging: Formation Evaluation

By E Kofi Sakyiamah | #Well_Logging_Formation_Evaluation...

Formation evaluation in its broadest sense ranges from the macroscale of a geologic basin mapped from satellite imagery to the microscale of a (0:09) examined through a scanning electron microscope. The principal objectives of formation evaluation are to determine the size, the shape, and the lithology of a reservoir and to characterize reservoir properties such as porosity, permeability, and fluid composition.

Wireline logs are used for a number of purposes. For example, for a well-to-well correlations and construction of cross-sections, for subsurface facies analysis, for construction of synthetic seismograms, to provide data for subsurface structural and stratographic mapping, and to determine subsurface pressures and the presence of fractures.

Wireline logging is the common meeting ground for many diverse formation evaluation techniques. For example, geologists use wireline data such as deep meter logs to confirm or refine structural interpretations made from broad area imagery and outcrop studies.

Geophysicists use down hole acoustic logging techniques to determine velocity profiles in an area in order to calibrate and accurately interpret seismic surveys and engineers use a variety of logging techniques to design completion programs and estimate the composition and recoverability of reservoir fluids.
