Research & Production Centre “GEONEFTEGAZ” worked out and widely uses a frequency-time high-resolution electrical prospecting with the IP parameter recorded by logging and ground investigations (Fig.1). The method of recording with a fixed source and application of multichannel of measurements secure a high efficiency of field work, high accuracy of measurements and more detailed character of investigations.   

 HRES-IP is one of the basic geophysical methods applied by “GEONEFTEGAZ”. It is the most effective when identifying and delineating different-type non-structural deposits where the possibilities of standard seismic prospecting are limited. The technology has been tested and proved to be efficient at all stages of geological prospecting for oil and gas – regional, search, exploratory. The HRES-IP technology is applied for the evaluation of oil and gas saturation of objects under study, outlining of a hydrocarbon deposit, classification of discovered and prepared structures with respect to their fluid saturation, and optimization of production drilling in the course of development of hydrocarbon deposits (Figs 2, 3).  

The mathematical software elaborated by “GEONEFTEGAZ includes a system of processing and interpretation of HRES-IP data, solution of direct and reverse tasks, 3-D modeling of objects under study.

Such approach secures a fast and effective processing of large volumes of field data, identification of anomalous zones, their sorting as well as reliable delineation of oil and gas-bearing objects and their depth tying in a combination with seismic prospecting.
