Current exploration for oil is being conducted by governments, major integrated oil companies, independent oil companies and syndicates, all of whom have different interests. The interdependence of the various aspects of exploration, production, transportation, refining and consumption within the oil industry is obvious; but the interdependence of the producing, transit, refining, and consuming countries has only recently been realized by the world. Within the exploration branch of the oil industry the mutual dependence of geological and geophysical methods has become generally accepted over the past thirty years. Good early training and collaboration along the whole chain of exploration can solve many industrial problems, and education can solve the world‐wide problems between countries

The N~vling salt structure is located on the southern margin of the Danish Zechstein Basin. The present study of this structure is based on a detailed gravity survey, reflection and refraction seismic data, and well information. Apart from the exploratory well NØvling-l, and a shallower well Herning-l, a number of wells, mainly 20-30 m deep, were drilled in this general area (by the Geological Survey of Denmark). Through this combined study using geological and geophysical methods it is possible to distinguish several stages in the development of the N~vling structure. It is shown that these stages are closely related to faulting at the base Zechstein level. The faulting, which apparently started as normal faulting in the Triassic, triggered the first salt movements from the deeper parts of the basin to this peripheral area. The faulting was reactivated during the late Jurassic, resulting in the formation of a salt pillow. The tectonic regime changed in the post-Paleocene tertiary when transpressional movements along a prominent basement wrench fault became dominant. This ultimately resulted in the formation of a positive flower structure and the uplifting of the Saale Quatemary surface. At shallow depths the salt became dissolved creating a topographic depression above the flower structure. The present depression was formed at the beginning of the last late glacial time. Quatemary landforms in the N~vling area are therefore greatly influenced by recent tectonic events.

The article presents results of the research of disjunctive dislocations of the earth's crust in northern part of the Sakhalin Island by analyzing the fields of lineaments, which identified on basis of satellite surveys using the LEFA software package. The object of research was chosen not by chance: eastern part of territory of the north of Sakhalin Island is quite well studied by geological and geophysical methods in order to identify oil and gas-bearing structures, as well as in connection with the close attention to it after catastrophic Neftegorsk earthquake on May 28, 1995. The result of work of the predecessors made it possible for verify the reliability of results obtained and assess of prospects to using automated decryption technologies to identify seismically active zones. The purpose of work was to create maps of active fault zones on studied territory. In process of the work, the SRTM data and Landsat-8 satellite images for 2015-2020, obtained in eight spectral channels, were analyzed using algorithms for detecting the location of lineaments based on methods of mathematical processing of images using different algorithms. It was revealed that images obtained in the red, infrared zones of the electromagnetic spectrum (4, 5, 6, 7), and the panchromatic channel (8) are most informative for identifying disjunctive disorders. Based on the data obtained, maps of disjunctive disorders of Sakhalin Island on scale of 1: 500,000 compiled. The article has certain novelty due to fact that the LEFA technological techniques were first used for research the geologically complex structures of Northern Sakhalin. The main results of the work will be useful in choosing places for construction of economic and industrial facilities, as well as in the exploration, search and operation of mineral deposits.

В результате проведённой работы была получена информация о геодинамическом поведении ос- новных тектонических блоков Земной коры (ЗК) в границах Горной Осетии. Принимая полученную информацию как первичную, в рамках данной работы продемонстрировано несколько методических приёмов по её матема- тической обработке. В частности, приёмы интерполяции дискретно представленных данных позволили вы- полнить построение поля скоростей GPS-пунктов в условной системе координат, проведено сопоставление его с полем распределения сейсмической энергии по территории. Выявленные локальные деформационные аномалии ЗК логично вписываются в тектоническую схему региона, установленную независимыми геологиче- скими и геофизическими методами. As a result of the work carried out, information was obtained on the geodynamic behavior of the main tectonic blocks of the Earth’s crust (GC) within the boundaries of Mountainous Ossetia. Taking the information received as primary, within the framework of this work, several methodological techniques for its mathematical processing are demonstrated. In particular, the methods of interpolation of discretely presented data made it possible to construct the velocity fi eld of GPS points in a conventional coordinate system, and compare it with the fi eld of seismic energy distribution over the territory. The identifi ed local deformation anomalies of the ZK logically fi t into the tectonic scheme of the region, established by independent geological and geophysical methods.
