Detailed understanding of how a reservoir behaves also aids in deciding how to produce from each well. To maintain pressure and extract the oil from the rock, most reservoirs require water injection. However, if water enters a well it disrupts oil production. Our high-fidelity reservoir models, running on our in-house simulator, GigaPOWERS, capture the detailed fluid flow involved in active waterflooding schemes and enable us to design injection strategies. Such simulations reveal the rate of oil each well should produce, so that the water maintains reservoir pressure uniformly for optimal oil recovery rates.
This capability enabled the company to decrease oil-water separation. Our models also help to pinpoint the optimum position for surface production facilities such as water separation.
The decrease in separation costs, and the reduced need for this process, reduces power consumption, saving energy and, as a result, lowering emissions.
In addition, the technology is integral to our reserve calculations and production forecasts, which ensure we maintain the capability to respond to global demand changes.
