How to obtain reliable S-impedance from P-wave data

Standard AVO analysis can create errors leading to false prospects. Elastic impedance offers method to give more correct results and fewer dry holes

Large data volumes can be handled cost-effectively

Results of a solution to storage/retrieval/ management, as developed by a service company alliance, is overviewed for a Conoco business unit

Producing partial waterdrive gas reservoir at high rate maximizes profitability

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

Small-scale 3-D seismic shoot adds new oil reserves

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.

Solid propellants provide cost-effective stimulation in marginal wells

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

Web-based pump-off controller reduces electricity costs

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