1 Using highly accurate satellite topographic mapping to accelerate oil and gas projects in Kurdistan Over 15 PhotoSat Kurdistan stereo satellite topographic mapping projects Gerry Mitchell PhotoSat President
2 Using highly accurate satellite topographic mapping to accelerate oil and gas projects in Kurdistan Over 400 global PhotoSat stereo satellite topographic mapping projects
3 30cm elevation mapping accuracy Engineering quality satellite topographic mapping accelerates work programs and prevents delays in all phases of oil and gas projects.
4 30cm elevation mapping accuracy accelerates and avoids delays for: Geological targeting Seismic surveys Well sites Access roads Oil and Gas Facilities Pipelines
5 Satellite Mapping for Geological Targeting Major structures West Tawke Anticline satellite topography 3D view looking east
6 Satellite Mapping for Geological Targeting NW striking faults Slope direction
7 Satellite Mapping for Geological Targeting Kirkuk thrust fault surface trace
8 Satellite mapping for seismic surveys Improves seismic survey planning Reduces source point scouting Improves seismic safety Improves seismic quality
9 Satellite mapping for seismic surveys Seismic survey access route scouting
10 Satellite mapping for seismic surveys Proposed 3D seismic survey plotted over a satellite topographic image
11 Satellite mapping for seismic surveys 1 km Proposed 3D survey seismic source types Red areas: slopes > 15% grade
12 Satellite mapping for seismic surveys Proposed 3D survey seismic source types
13 Satellite mapping improves seismic survey safety Avoid vibroseis source points on steep slopes X X X X X X X X X Red = slope > 15 degrees
14 Satellite mapping for seismic surveys Seismic survey xyz source and receiver point location QC
15 Satellite mapping for seismic surveys 35km Seismic source points in blue in error by > 1m in elevation
16 Confirmed Seismic Safety Improvements Feedback from BP Libya Advance scouting reduced by ~ 80% The stereo satellite topography and imagery gives an accurate enough picture so that only a few areas require field visits in advance, to identify inaccessible source-points and to plan for efficient disposition of the vibrator trucks, reducing the number of project personnel days. Safer Vibroseis operations Accurate maps of the ground slope enable mapping of no-go zones for the vibrator trucks, lessening the risk of overturning the trucks on steep inclines. Fewer surveyor field days Combined with Seismic Recorders with built in GPS receivers, the stereo satellite elevation mapping can eliminate surveying of the seismic receiver elevations.
17 Improved Seismic Quality Feedback from BP Libya The stereo satellite topography provides the necessary source and receiver location elevation accuracy for seismic processing. The stereo satellite topography can be used to quality control the source and receiver elevations and eliminate the need for additional surveying. Source-points are surveyed using GPS systems mounted on the vibrator trucks. Elevation accuracy can be poor during GPS start up and during times of low GPS satellite visibility. For seismic receivers with GPS antennas the stereo satellite topography eliminates the need for any surveying of the receiver elevations.

78 Stereo satellite elevation mapping PhotoSat technology
79 PhotoSat stereo satellite topographic mapping technology: PhotoSat satellite topography generally has over four times the elevation mapping accuracy and resolution of conventional mapping technology using the same satellite photos. In areas of steep rugged terrain PhotoSat s method has an even greater advantage.
