Models for Domestic and International Environmental Monitoring Using Satellite and Aerial Photographic Remote Sensing

John S. Janks, Alfredo E. Prelat, G. Serpell Edwards, John D. Wieser

Models that apply remote sensing technology to environmental monitoring have been developed for U.S. and international oilfield operations. Satellite and aerial photographic remote sensing assessment technology was used from beginning to end of the hydrocarbon exploration and production process. At the onset of the exploration process, environmental baselines were created to document conditions prior to seismic and well drilling activities. The satellite and aerial photographic data provided a low-cost method to assess vegetation health and cover, soil erosion, and man-made construction before oilfield activities began. These assessments outlined environmentally-sensitive areas and assisted in locating the seismic lines, well sites and access roads. Periodic evaluations w re also made during the life of a field to chronicle changes and identify potential problems. Closing of wells, sites and fields were also documented and any effects on the environment identified.

Satellite technology has the ability to identify contamination and its impact on the environment by analysis of spectral responses in the visible and infrared regions of the electromagnetic spectrum. Hydrocarbon spills and vegetation affected by salt water were among the types of contamination identified. Where available, aerial photographs were used in conjunction with these data to provide higher resolution and a greater historical perspective of a region. Roadways, pipelines, manmade objects, and waterways (among others) were added to the images using Geographic Information Systems (GIS) technology.
