LIDAR FOR REMOTE UNDERWATER EXPLORATION AND MONITORING OF HYDROCARBON DEPOSITS

SKU0027
DESCRIPTION

The laser spectroscopy assembly can conduct remote, non-contact, continuous areal and profile scanning with simultaneous identification of areas of gas anomalies by identifying the concentration of a set of indicative chemical elements and compounds. The use of an innovative and ecologically safe technology of remote underwater exploration and monitoring of hydrocarbon deposits in severe climate conditions of the continental shelf makes it possible to effectively search for oil and gas deposits and increase the work efficiency at the less explored Russian aquatic areas with minimal time investments.

The assembly consists of two parts: a submersible watertight frame and a control device that’s located on a surface craft. With the help of a strobe electro-optical converter which sends the image to a CCD matrix the assembly registers emission that’s scattered by an underwater object. Then, a program processes the image and transfers the spatial distribution of intensity into spectra.

Based on the characteristic features of the resulting spectra, it is possible to find and identify hydrocarbons that are present in water. The conduct of geological exploration in the waters of Russian seas is feasible within the limits of a technically accessible area of development of hydrocarbon deposits (at depths of no more than 50 meters).

The laser spectroscopy assembly for remote underwater exploration and monitoring of hydrocarbon deposits was developed in collaboration with Krylov State Research Center, Vavilov State Optical Institute, and All-Russian Research Institute of Oil Geology.
