MOBILE METHODS OF SATELLITE IMAGES AND PHOTO IMAGES FREQUENCY-RESONANCE PROCESSING: RESULTS OF ADDITIONAL TESTING ON OFFSHORE DRILLING SITES

Abstract

The results of application of mobile direct-prospecting technology of frequency-resonance processing and interpretation of satellite images and photographs at the areas and sites of exploratory wells drilling on the Norway, Israel and China offshore and at hydrocarbons deposits at great depths are presented. Experimental research of a reconnaissance nature was carried out with the aim of demonstrating the efficiency, effectiveness and informativeness of direct-prospecting methods. A fundamentally important result of studies at the drilling site of Calypso exploratory well is the fact, that additional features of instrumental measurements have been established. So, in the case of fixing responses at the frequencies of siliceous rocks at survey sites, it is advisable to carry out instrumental measurements for hydrocarbons (oil, gas, condensate), taking into account a relatively long-time interval. It is also necessary to carry out instrumental measurements in order to fix responses from hydrocarbons at different depths (up to 7-10 km) from the upper part of cross-section. Only within one of the five surveyed local sites with the locations of project wells on the Norwegian offshore, low-intensity signals were recorded at the frequencies of gas, methane-oxidizing bacteria, and phosphorus. In this area, it is advisable to carry out frequency-resonance processing in a detailed mode of images of different areas, as well as to scan cross-section in order to assess the depths and thicknesses of productive horizons. The Hercules structural uplift within the Block 23 location on Israel offshore is formed by a volcanic complex filled with siliceous rocks. In the contours of volcanoes of this type, conditions for the synthesis of hydrocarbons at the boundary of 57 km are not created. Drilling exploratory wells on this structure is impractical. At the surveyed well drilling site on the Chinese offshore, gas frequency responses were recorded from the surface, as well as by scanning in four intervals of the salt cross-section. Responses at the frequencies of condensate, gas, white phosphorus and salt were also recorded from the surface. The total thickness of four intervals of fixation of responses at gas frequencies in cross-section significantly exceeds the thickness value of the gas-bearing collector given in the informational message [10]. Reconnaissance studies carried out on the offshores of Norway, Israel and China indicate that mobile direct-prospecting methods can be used to assess the prospects of oil and gas potential (ore potential) of large prospecting blocks and local areas (including those put up for auction), the selection of optimal locations (sites) of exploratory and production wells, assessment of the prospects of oil and gas deposits discovering in the deep horizons of cross-section, searches and localization of deep channels for the migration of chemical elements, fluids and mineral matter into the upper horizons of cross-section. The use of mobile and low-cost technology will significantly speed up the geological exploration process for hydrocarbons, natural hydrogen, ore minerals, as well as reduce financial costs for its implementation.
