INVESTIGATION OF PRIMARY DRIVE, SECONDARY DRIVE, AND TERTIARY DRIVE USING AN ADVANCED RESERVOIR SIMULATOR

Abstract

Oil and gas production is essential to our productivity and fulfilling energy demands in the upcoming decades but sustainability should play a huge factor on how that is done. In this work, we model primary, secondary and tertiary drive to understand the production of oil in short and long term projects using an in-house novel reservoir simulator. Water, gas, and CO2 injection play a huge role in the current oil and gas industry as reservoirs are being depleted and need a little bit of push to help extract petroleum. Water injection was introduced with the presence of effective capillary pressure to help understand how reservoir properties model the project once production occurs. After modeling the cases with the presence of effective capillary pressure, the Water-wet reservoir yielded in higher production as we used water as a source of injection that helped push the oil while being attracted to the rocks. Later gas injection was introduced with no presence of capillary pressure and that yielded in higher oil production. Since the oil and gas industry is always coming up with new methods to improve overall efficiency of the project, water alternating gas injection (WAG) was implemented. This method ended up in higher oil production compared to the standalone of either water or gas injection and this can be due to both strengths being implemented into the reservoirs helping push the oil. Finally CO2 injection was implemented in the Dukhan field that is present in Qatar to help achieve the Qatar Vision 2030 by reducing carbon footprint. CO2 injection yielded in higher production compared to just producers and this helps sequestrate the CO2 inside the reservoir. An increase of 38% of recovery was achieved using the CO2 method which achieves our goal of supplying energy in a sustainable manner.
