Elm Coulee Field Study
Modeling Examines
Gas Injection Results
For Improving
Bakken Recovery
By B. Todd Hoffman
GOLDEN, CO.-While initial production rates are high from horizontal
wells in ultratight oil formations, reservoir recovery factors are very low,
averaging in the range of 5-10 percent. The low primary recovery factors are
largely the result of the ultralow matrix permeabilities. And, unlike
conventional reservoirs, in which waterflooding is the main choice for
improving oil recovery by providing pressure support and sweeping oil to
production wells, waterflooding does not appear to be a viable secondary
recovery option in shale oil reservoirs because of low permeability/injectivity.
Beyond primary artifical lift, gas injection may be an effective alternative
for improving recovery rates in tight oil reservoirs such as the Bakken Shale,
where the source rock and the reservoir rock are one and the same, and
permeabilities are measured on the microDarcy scale. A Colorado School of
Mines study examined a four-section area of the Elm Coulee Field in eastern
Montana to evaluate the impact of three gas injection schemes: carbon
dioxide, immiscible hydrocarbon, and miscible hydrocarbon.
