New Oil Recovery From an Old Field: A Case Study in the Western Desert of Egypt
A recent simulation study on the Kharita reservoirs of the Badr-1 (BED-1)
field showed underestimated volumes of the original oil in place (OOIP). With
no further activities, predicted performance indicates total ultimate recovery
from the Kharita reservoirs will be 53.5% of the OOIP. All future sidetracks
and new locations were terminated on the basis of limited remaining reserves as
per the preliminary simulation predictions. Because of inconsistencies between
the current average oil-production rates and the large volumes of cumulative
oil produced, and combining the indicated pressure performance with the driving
mechanisms, a reservoir-management revision and performance-review study were
made to explain discrepancies and inconsistencies of the Kharita reservoirs
performance in BED-1 field. The focus was to understand reservoir performance
rather than just obtain a history match.
