Libya

As-Sarah field

Conducted a field study to evaluate the proven producing and undeveloped attic reserves. Performed volumetric analysis to determine reservoir volume and percentage of oil recovered in the swept area down to the oil-water contact as defined from producing water cuts and production logging data.

Nakhla field

Combined an audit of the structural interpretation, which incorporated a review of seismic and well data, with results of the independent petrophysical analysis to determine the original in-place oil reserves. The results of the volumetric analysis were compared to the geological model and reservoir simulation results and incorporated into the analysis of the proved reserves of the field.
