BAKKEN NEWS Study to look at CO2 in oil recovery

Research Center in Grand Forks wants to fi nd out if the same principle will work on the very deep Bakken shale forma- tion. They’ll get $475,000 from the state’s Oil and Gas Research program to probe the question. It’s expected the study will take 15 months and cost more than $1.3 mil- lion. John Harju, an associate researcher
who will help lead the study, said this work will be above ground in the labora- tory, using Bakken core samples and data from oil wells. The idea is to understand how the gas
interacts with the oil and with the source rock where it’s found.

terranean water fl ood is used to push out more oil. But Harju said it’s already pretty well understood that a water fl ood won’t work in the Bakken shale. Harju said wa-

has a very high potential to enhance recovery in the Bakken. If so, the study could eventually pay huge dividends. The EERC said only 3 to 5 percent of
available oil can be pumped out of the Bakken now and even small technologi- cal improvements, like CO2 injections, could increase that amount by billions of barrels.
ter fl oods — with water injected into one place and water and oil pumped out of another — help oil companies un- derstand the reservoir. Without that understanding and us-

Three oil compa- nies — Marathon Oil, Denbury Resources and TAQA North — will help fund the study. They’ll also provide Bakken core samples and data like well temperature and pressure, Harju said. Gov. Jack Dalrymple,
