• Hydrocarbon traps frequently display anomalous geothermal gradients.
• Target E.C developed a computer program which verify, test, correct, plot and analyse BHT records to identify geothermal gradient anomalies of HC entrapment.
• The report is valuable to new and established explorers of North Sea to:
• Recognise geothermal signature of proven traps and use it to identify early wells that may have bypassed or stopped short of HYDROCARBON TRAPS.
• FOCUS resources on assessing tracks of hydrocarbon migration and entrapment.
• Identify KEY WELLS with reliable geothermal gradients for BASIN ANALYSIS.
• Report includes: discussion of geothermal anomalies , 300 plots and figures, 5 enclosures showing: locations of 500 wells, locations of key wells, surface temperature and geothermal gradient contours, geothermal gradient anomalies and attributes of proven and potential hydrocarbon traps (SCALE 1:250,000).
• An ASCII file documenting hundreds of BHT data used in this study is available.
