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

Russell W. Pfeil, James M. Ellis

Good management of an oil field and compliance with ever-increasing environmental regulations is enhanced by technologies that improve a company's understanding of field/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 field 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 field. However, even when the data 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 data about the oil field.

Chevron has been evaluating the capability of Geographical Information System (GIS) technology to integrate images, maps, and tabular data into a useful database that can help managers and workers better evaluate conditions in an oil field, plan new facilities, and monitor/predict trends (for example, of air emissions, groundwater, soil chemistry, subsidence, etc.). Remote sensing, CAD (if formatted properly), and GPS data 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 data collection and conversion from legacy data 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 field for integrating GPS data with field observations and programs.
