Simulation of underground storage / UM EL-Radhuma Formation-Ratawi field

الملخص

The aim of this study is to investigate the feasibility of underground storage of gas in Um El-
Radhuma formation /Ratawi field. This formation is an aquifer consisting of a high permeable dolomite
beds overlain by impermeable anhydrite bed of Rus formation. Interactive petrophysics (IP), Petrel RE
and Eclipse 100 softwares were used to conduct a well log interpretation, build a reservoir simulation
model and predict the reservoir behavior during storage respectively. A black oil, three dimensional
and two phase fluid model has been used. The results showed that the upper part of Um El-Radhuma
formation is suitable for underground gas storage, because of the seal of its cap rock and capability of
reserving gas in the reservoir. It was found that available volume for storage is 14.3 billion cubic feet
with a structural closure of 45 m. the optimum injection rate has been calculated also.
