In recent years the oil industry has made significant progress in the search for oil that lies beneath the seabed through the sampling of water and soil samples from the sea floor and analysis for the presence of hydrocarbons leaking from the oil fields.
Shallow coastal shelves to a depth of 500m are fairly well analyzed and currently being exploited. Exceptions are the mid- and deep-water shelves up to 500-5000m depth, which according to the recent studies have big hydrocarbon reserves. Extracting them from such great depths requires a thorough deep geochemical prospecting using special near-bottom sampling technology which does not exist at the moment.
Geochemical coastal sampling produces small samples, but a large number of them can give a fairly representative amount of information. The data is analyzed by an appropriate method such as factor analysis using special software.
This allows to predict hydrocarbon deposits beneath the sea bed.
Offshore geochemical studies may be particularly successful because of the possibility to obtain environmental parameters such as temperature and pressure.
Geochemical research is in pretty high demand in the oil industry and is currently the standard practice in any major offshore program. Existing research methods include special ships, miles of cable and a lot of time and money.
The proposed new concept does not use cables, it is completely wireless. This is a stand-alone device that can be easily deployed from general boats and ships. This will reduce the research cost by 75 % compared to the conventional offshore geochemical methods.
