Seismic exploration

3D seismic survey is conducted for a detailed study of geological structure of the sites potential in terms of the hydrocarbon accumulation, identification of the well locations, and along with methods for monitoring over development of the production fields.

There are 9 companies specialized in conducting all types of field seismic surveys provided with all necessary equipment and personnel within the Holding, these companies operate with application of high-performance development technologies:

• Flip-Flop – the technology is based on the continuous "shooting" of excitation points by two groups of vibratory sources, reducing the time required to move the source groups from one excitation point to another.

• Slip-sweep is a technique of overlapping the vibration sweep-signals, where vibrators at different excitation points operate simultaneously and independently of each other. The recording is performed continuously along with it.
