Estimation of water influx and oil reservoir performance prediction in the volve oil field

Abstract EN

This paper is conducted in order to determine the water influx in the Volve oil field situated in the Southern Viking Graben in the North Sea in block 15/9, approximately 200 kilometres west of Stavanger at the southern end of the Norwegian sector.

Material balance (MB) equation is used as principal method in order to achieve the objectives of this work, predicting reservoir future performance over a stated period of five years is considered as the second part of the work.

A variety of data particularly pressure, volume and temperature data, production and reservoir data are entered in the MBAL software and computed in Excel software using material balance equation.

The result showed that the reservoir had a water influx of 67,678 Sm3 before injection requiring the use of secondary recovery method, water injection at the early stage of production.

Subsequently, cumulative oil production predicted a total amount of 10.77 MMSm3 over a period of five years.

This therefore implies that thanks to the model obtained which is the pot model production prediction can be made for any date in the future.
