MBAL Software, Driving Reservoir Mechanisms, Libyan Oil Fields, Material Balance Method
Abstract
Material Balance (MBAL Software) is software used for efficient reservoir development and helps the engineer better define reservoir drive mechanisms and hydrocarbon volumes. Natural forces in the reservoir that displace hydrocarbons out of the reservoir into the reservoir bore and up to the surface. This paper estimates and compares driving mechanisms using dynamic simulation in MBAL software and the predictive material balance method after history matching of both of these models. Results from this paper show the functionality of MBAL in terms of history matching and performance prediction. The objective of this paper is to estimate water influx with the identification of the water influx model parameter and to estimate the reservoir drive mechanism for eight Libyan oil reservoirs. The simulator results show the reservoir pressure history curve is matching the stimulation curve; this gives a good indication of the input data that has been entered into the model. The driving mechanism for all those reservoirs comes from three natural forces, which are fluid expansion, PV compressibility, and water influx.
