| The detection of oil seepage has often given the oil exploration industry the first indications of sub-surface and sub-sea oil accumulations. Some authorities claim that 95% of all discoveries were made because of identified seepage in one form or another. The development in 1990 of the Seepfinder technology added a new dimension to offshore oil exploration and provided the first reliable, high sensitivity offshore oil seep detection system. Mounted in a light aircraft, and steered by satellite GPS navigation, Seepfinder discovers the presence of thin molecular oil films on the surface of the sea. Seepfinder identifies these films and recordes those which have risen from the sea bed. "Seeping" oil rises from the reservoirs via geological faults to the sea bed, often driven by gas pressure. It also records the spectral characteristics of the oil and can detect films right down to the “clean” water limit of 50 ppm. No other system can provide such a comprehensive database to the oil explorationist, and so rapidly. Seepfinder can typically acquire 1,200 line Km of data per day. Seepfinder can save tens of millions of dollars in wasted offshore exploration activity through the availability of positive or negative data – both can be equally valuable, focussing scarce resources directly onto potential oil deposits. The Oilsearch service offers a combination of gravity, magnetic and oil seep detection technology in a single aircraft, providing a unique, unrivalled and low cost exploration tool for the offshore oil exploration industry. |
