Sažetak

Despite the global efforts to transition towards environmentally friendly energy sources, traditional resources such as oil and gas continue to play a crucial role in meeting energy demands. The features of the following geophysical methods application for mineral exploration are considered: magnetic, electrical, radioactive, seismic, well logging, as well as multispectral aerospace surveys and field spectrometry. Among these methods, the gravity method, specifically its astrogeodetic variant utilizing zenith cameras and GPS positioning, emerges as a highly effective approach for detecting oil and gas deposits. A comprehensive review of literature sources and patent documentation is conducted, focusing on the construction and accuracy characteristics of both analog and digital zenith cameras. The methodology involving a digital zenith camera and GPS receiver for determining the deflections of the vertical in a test site within the Chernihiv region (Ukraine) is examined. The positive results obtained from this exploration not only validate the effectiveness of the approach but also enable the possibility of oil-bearing horizons identification. The paper derives formulas for calculating the accuracy of the deflections of the vertical determinations through the astrogeodetic method, specifically tailored for local areas. These formulas empower researchers to conduct a priori accuracy calculations, facilitating the determination of permissible distances between zenith cameras and GPS receivers when installed separately, ranging from 1.05 m to 1.76 m.
