Solid propellants provide cost-effective stimulation in marginal wells
Dr. Richard A. Schmidt, J Integral Engineering, Inc., West Linn, Ore, and Wilford M. Ashley, Ashley Oil, Inc., Casey, Ill.

Many oil and gas wells can be stimulated effectively with a progressively burning, solid propellant that produces multiple fractures.

Producing partial waterdrive gas reservoir at high rate maximizes profitability
Dana Westphal, Ocean Energy, Lafayette, La.; and John McMullan, Louisiana State University, Baton Rouge, La.

Ocean Energy achieved a 70% recovery and maximized profitability from a downdip waterdrive gas completion by aggressively producing the zone at high rates.

Web-based pump-off controller reduces electricity costs
Doug Torr, CamWest, Inc., McKinney, Texas; and Dan Mooney, Aurion Technologies, Inc. Dallas, Texas

CamWest, Inc., an independent based in Denver, Colorado, and McKinney, Texas, operates more than 120 oil wells in Lander, Wyoming.

Small-scale 3-D seismic shoot adds new oil reserves
Dale Helpingstine; and Don Williams, Shakespeare Oil Company; Phil Caserotti; Geophysical and Geological Consultant; and Steve Gustison, Midwest Region PTTC

Shakespeare Oil redefined the structural interpretation of the Devonian Geneva dolomite reservoir in Tonti field, Marion County, Ill., using data from a 0.375-sq-mi 3-D seismic survey.
