Upgrading remote sensing with GIS technology in support of petroleum operations
- Chevron Overseas Petroleum Inc., San Ramon, CA (United States)
Remote sensing data (including satellite and airborne) that are integrated with CAD and GPS have been successfully employed to improve understanding and mapping of geology, logistics, environment, and facilities. Methods developed over the years have provided the industry with reliable and cost-effective hardcopy and digital products. However, even when the data collected by remote sensing, CAD, and GPS are spatially co-registered and integrated into a high performance workstation, users have been unable to query, model or interactively link to spreadsheets (tabular data) that can contain important attribute information about features seen on the images and maps. This information gap is being rapidly overcome by integrating images, CAD maps, and tabular data with Geographical Information System (GIS) technology. An end result is greater appreciation and broader application of remote sensing by managers and workers in the petroleum industry. A major obstacle to establishing GIS for an overseas operation is the initial cost of data collection and conversion from legacy database management systems and hardcopy to appropriate digital format. GIS applications include using remote sensing images as the basis for documenting changes through time, linking to GPS to improve navigation in the field, verifying well locations and querying/updating well databases, planning facilities, and creating maps of features interpreted from the imagery. The integration of remote sensing, GPS, and now GIS is essential for planning operations in areas where maps are either out-of-date or unavailable.
