MIDWEST, Wyo. (AP) _ A process that coaxes more oil out of the ground is giving new life to marginal oil wells, including those in Oklahoma.

Anadarko Petroleum Corporation is using carbon dioxide to revive the Salt Creek field in Wyoming. Anadarko has other CO2 flooding projects in Kansas and Oklahoma.

Houston-based Anadarko is investing up to $624-million in Salt Creek. That includes building a 125 mile pipeline to carry the CO2 to the field, installing another 200 miles of new pipe within one two-square-mile area and hauling in huge compressors to push the gas underground.

With world crude oil prices hovering between $50 and $60 a barrel, the investment should pay handsomely. Anadarko hopes to draw at least another 200 million barrels of oil out of the field.
