DIRECT-PROSPECTING TECHNOLOGY OF SATELLITE AND PHOTO IMAGES FREQUENCY-RESONANCE PROCESSING: RESULTS OF TESTING ON THE TAJIKISTAN TERRITORY

Abstract

The results of the direct-prospecting technology of satellite images and photographs frequency-resonance processing testing at oil and gas fields and during a reconnaissance survey within big blocks in Tajikistan are presented. Experimental researches of the reconnaissance nature were carried out with the aim of demonstrating the performance, efficiency and information content of direct-prospecting methods. During the work conducting, frequency-resonance processing of photographs of local areas from six hydrocarbon fields, as well as the exploration well drilling site, was carried out. At three oil and gas fields, a certain number of detailed experiments were carried out with the implementation of an expanded set of instrumental measurement procedures. Experimental measurements have shown that by scanning with a relatively large step of 1 m, the depth intervals in cross-section are recorded, within which it is advisable to search for individual productive formations. Individual layers (solid) can be identified in cross-section when scanning with step of 1 cm or finer. Experiments with various rock samples indicate the possibility of frequency-resonance methods using to determine the type of reservoir rocks in productive intervals of the cross-section, seals above deposits and individual layers. The frequency-resonance method of the photographs processing can also be used to quickly determine the presence (absence) of oil, condensate and gas in the core, extracted from wells. Experimental measurements using individual samples of oil and condensate indicate the feasibility of using samples of oil, condensate, gas, as well as reservoirs and seals rocks from drilled wells in the study area, when the detailed work performing. Additional use of samples from the work area will help increase the information content and reliability of the results of using the direct-prospecting methods of satellite images and photographs frequency-resonance processing and decoding. In general, the use of super-operational and low-cost direct-prospecting technology will significantly speed up the exploration process for oil, gas, natural hydrogen and ore minerals, as well as reduce the financial costs of its implementation. Mobile methods of direct-prospecting technology can also be used to study the deep structure of the structural elements of the Earth, establish the genesis of ring structures, examine volcanic complexes of various types. The direct-prospecting technology can also be successfully used during the exploration of poorly explored areas and blocks within known oil and gas fields. Proven super-mobile technology of satellite images and photographs frequency-resonance processing is recommended for practical use on the territories of different countries for the purpose of preliminary assessment of the prospects for oil and gas content, ore content and water content of poorly studied and unexplored prospecting blocks and local areas.
