RESERVOIR CHARACTERIZATION AND RESERVE ESTIMATION IN AKINGS FIELD

ABSTRACT

The increasing demand for hydrocarbon-based resources since 20th century provoked intensified exploration for oil and gas accumulation in most sedimentary basins of the world. This gave birth to the widespread study of the Niger Delta Hydrocarbon Province, which is one of the most prolific basins in the world. This study attempts to access the economic viability of the C reservoir in the Akings Field. Suites of wireline well log data for four wells and a 3D seismic data of the Akings field were evaluated to simulate the reservoir. With the use of the Schlumberger petrel software, and integration of both data sets, seismic section was generated through which 32 faults and one reservoir horizon across the wells were mapped. The data was used to achieve a seismic well tie as well. A time-depth surface map of the reservoir was generated using different seismic attributes such as RMS amplitude and maximum amplitude and average energy. The reservoir, has a net thickness of about 176.5ft and payzone thickness of 129.90ft; it has total porosity of 31%, effective porosity of 28% permeability, 2436.80mD, fluid type: oil and water; hydrocarbon saturation of 68%, and a prospect area of about 1049.46 acres. The combination of the aforementioned information, therefore have been used to estimate the reservoir fluid volume at surface condition; which is about 222,943,812.21bbl. This information therefore will guide developmental decision - making process.
