Abstract: Evaluating GIS for Establishing and Monitoring Environmental Conditions of Oil Fields

Russell W. Pfeil, James M. Ellis

Good management of an oil Previous HitfieldNext Hit and compliance with ever-increasing environmental regulations is enhanced by technologies that improve a company's understanding of Previous HitfieldNext Hit/production facilities and environmental conditions that have occurred to both through time. In Nigeria, Kazakhstan, Indonesia, and offshore Cabinda, remote sensing, computer-aided drafting (CAD) and Global Positioning System (GPS) technologies have effectively been used by Chevron to provide accurate maps of facilities and to better understand environmental conditions. Together these proven technologies have provided a solid and cost-effective base for planning Previous HitfieldNext Hit operations, verifying well and seismic locations, and locating sampling sites. The end product of these technologies is often cartographic-q ality hardcopy images and maps for use in the office and Previous HitfieldNext Hit. However, even when the Previous HitdataNext Hit collected by these technologies are spatially co-registered and integrated into a high-performance workstation environment, users are unable to query, model, or interactively link to spreadsheets routinely used for collecting important Previous HitdataNext Hit about the oil Previous HitfieldNext Hit.

Chevron has been evaluating the capability of Geographical Information System (GIS) technology to integrate images, maps, and tabular Previous HitdataNext Hit into a useful database that can help managers and workers better evaluate conditions in an oil Previous HitfieldNext Hit, plan new facilities, and monitor/predict trends (for Previous HitexampleNext Hit, of air emissions, groundwater, soil chemistry, subsidence, etc.). Remote sensing, CAD (if formatted properly), and GPS Previous HitdataNext Hit can be integrated to establish the spatial or cartographic base of the GIS. A major obstacle to establishing a sophisticated GIS for an overseas operation is the initial cost of Previous HitdataNext Hit collection and conversion from legacy Previous HitdataNext Hit base management systems and hardcopy to appropriate digital format. However, Chevron routinely uses GIS for oil spill modeling and is now usin GIS in the Previous HitfieldNext Hit for integrating GPS Previous HitdataNext Hit with Previous HitfieldTop observations and programs.
