... studies of the carbon dioxide injection process, the Ivanić oil field was chosen as the first candidate for the application of this EOR method. In order to rebuild the Gamma 2/4 reservoir pressure before the pilot project, injection of water started in 2001. The WAG CO 2 process is being conducted...

... with respect to arrest of reservoir pressure decline, reduced water production and reduced producing GOR, resulting in improved oil recovery of around 42% of the original oil-in-place. Rejuvenation of the reservoir by successful tapping of undrained / unswept oil following polymer flooding even after around 40...

...) is at or near current reservoir pressure, (3) depositional environment analogous to several other reservoirs in BDO, and (4) considered one of three large targets required to implement large scale gas flooding in BDO. This paper presents the methodology used in the screening of 1,000+ reservoirs and the unique...

... strategy, the production will stay on plateau for only 3 years. This is mainly due to the rapidly falling reservoir pressure. The remedial plan is to initiate a full field water injection project to maintain reservoir pressure. The primary objective of this project was to extend production plateau as long...

.... The Jatibarang Field primary recovery is only 16.2%, and the current reservoir pressure is as low as 500 psia. The reservoir performance shows the driving mechanism in this zone is very weak water influx. Therefore a Waterflood and/or EOR Program need to be evaluated to increase oil recovery. Based...

... It should be noted that at no time is the system analysis model automatically changed by this process. Over time the model will become less and less accurate due to changing reservoir pressure and will require periodic, manual recalibration. This was intentionally designed into the process...

... injection would not be able to achieve miscibility with the crude oil at the current reservoir pressure, or even if the pressure is increased to the initial reservoir pressure. Equation-of-State (EOS) model also shows that the Multiple Contact Miscibility Pressure (MCMP) for CO 2 and produced hydrocarbon...
