Unrecovered oil in Denver Basin Fields, remaining after waterflooding is giving operators cause for alarm, and has research engineers looking for ways to keep wells producing at an economical rate. Many waterfloods are approaching the economic limit, or will reach that point in 5 yr or so, and the floods are leaving 60% of the oil behind - 500 million bbl in the Colorado portion of the basin, and almost that amount in Nebraska. Steps are being taken to find ways of recovering this original oil in place. Besides laboratory experiments involving various recovery techniques, several field pilot projects are testing different mechanisms, as follows: (1) Pure Oil Co. has injected a slug of LPG into one well in a watered- out portion of the Adena reservoir; (2) Mobil Oil Co. has slugged Phegley Field, S. of Brush, Colo., with LPG; (3) Pan American Petroleum Corp. is operating a pilot fireflood in a watered-out portion of Sloss Field, Kimball County, Neb.; (4) Pan American is trying wettability reversal in an unwatered-out portion of Harrisburg Field, Banner County, Neb.; and (5) Marathon Oil Co. is trying LPG injection in Huntsman Field, Cheyenne County, Neb. These projects are classified ''top secret'' and results may not be known for some time.
