Bottom Line: Once a decision is made to divest an oil and gas asset, time is of the essence to take advantage of opportunistic market conditions or realize cash flow quickly. The marketing objective is to get relevant data to qualified prospects quickly and efficiently. Lehman Brothers employed Petris Technology, Inc.'s Internet Data Room (IDR) software to present data online for a 500-well Gulf of Mexico/Louisiana divestiture. This approach saved Lehman, the marketer, and the seller more than 100 hr of time. Savings in normal paper, copying and distribution costs incurred with a physical data room offset the IDR costs. Competition was enhanced, because each prospective purchaser had an opportunity to begin evaluating the package without leaving his office. Each prospective purchaser who reviewed the package saved thousands of dollars and many hours by being able to review it more efficiently. IDR access history provided real-time feedback to the marketer and its client about the interest levels of prospective purchasers.

Horizontal Waterflooding Increases Injectivity and Accelerates Recovery

Bottom Line: Grand Resources is applying horizontal waterflooding in northeast Oklahoma's Bartlesville Sandstone to realize much higher

injectivity, improved sweep and accelerated recovery. The combined effect should improve present value (PV10) over five-fold, compared to conventional vertical waterflooding. Grand has successfully drilled an injection and two production wells using short-radius drilling techniques. Real-time learning and innovation proved effective in controlling costs. Initial injection, which is just now beginning, confirms higher injectivity. More time, but not may months, is needed to realize the oil production response that simulation predicts.

Progressing Cavity Pumps, Insights From 14 years in a Southern Oklahoma Waterflood

Bottom Line: Oak Resources, Inc. (Oak) began employing progressing cavity pumps (PCP) in the West Hewitt Penn Sand Unit, a waterflood in southern Oklahoma, in September 1988. Unit wells produce 200 bfpd to 1,400 bfpd from about 2100 ft. Initial PCP installation costs were found to be 25% below those of beam-pump units and electrical submersible pumps (ESPs). Electrical power savings are 5% below beam-pumped units and 35% below ESPs, for comparable production rates. Through an evolution of PCP configurations and designs, up to a seven-year stator life is now expected, with only minor repairs. Adjustable rates at the surface, low capital costs, low repair costs and high electrical efficiency make PCPs attractive in this type application.
