Abstract

Carbon-dioxide is considered one of the major factors for climate change despite its importance for the existence of life on our planet. Apart from several other options, CO2 can be sequestrated into the depleted petroleum reservoirs to maintain the CO2-ratio. It can also be used for enhanced recovery due to its solvent-like properties at certain temperatures and pressures. Reservoir modeling plays an important role in evaluating the pros and cons of CO2 sequestration in a particular reservoir. In this study, we present the preliminary modeling results from North Triumph Gas reservoir for CO2 sequestration and enhanced recovery. Keywords: reservoir modeling, history matching, CO2 sequestration. 1 Introduction Carbon dioxide is present in the atmosphere and plays a critical role in the photosynthesis reaction that allows plants to grow and its presence is crucial. It also acts as an insulator in our atmosphere so that the global surface temperature remains within a reasonable range. However, it has come to the attention of many scientists that anthropogenic CO2 may be altering the world’s climate. Carbon dioxide is being emitted constantly at increasingly greater rates around the globe. The modern industrial age is contributing great amounts of CO2 to our atmosphere on a daily basis. There are several ways to reduce the concentration of CO2 in the earth’s atmosphere. The world, as a whole, could burn less fossil fuel or, the CO2 that is produced could be captured and stored for long term, or at least until the fossil fuel based economy becomes less significant.
