ON THE ISSUE OF THE APPLICATION OF MICROSEISMIC STUDIES FOR DIRECT SEARCH FOR HYDROCARBONS ON THE EXAMPLE OF KHAYAN-KORTOVSKY AREA
The article examines the problems of the study of seismic noise and microseisms for estimating the oil and gas potential of insufficiently studied areas with no possibility of 2D and 3D seismic surveys of high multiplicity. In the Tersko-Sunzhensky oil and gas field, there are the so-called satellite structures (Severo-Bragunskaya, SeveroMineralnaya, Severo-Malgobekskaya, Yuzhno-Khayankortovskaya, Severo-Eldarovskaya, and others) which are oil and gas prospective. The expediency of applying the technology of microseismic studies of such objects is considered because of insufficient knowledge of seismic prospecting and drilling, complex (ambiguous) geological structure and relatively low economic costs of the work. As a pilot facility, it is proposed to conduct microseismic studies in the Yuzhno-Khayankortovskaya area. The article provides data on the geological structure, geological and geophysical studies, the main parameters of the ICT technology and the expected results.
