Gravigenic disjunctive dislocations and related plicative structures are found in the sedimentary strata of many oil and gas-bearing basins of the world. Numerous oil and gas deposits are associated with such structures. The anticlinal uplifts of the sedimentary cover, which extend along the zone of the Krasnoritsky fault in the southeast of the Dnieper-Donets basin, are typical gravigenic formations. About one and a half dozen gas-condensate fields are connected with them. However, in the north-western part of the Krasnoritsky fault, between the Evgeniivka and Borivske deposits, no hydrocarbon deposits have been discovered in a strip with a length of almost 40 km. According to the results of the study of gravigenic tectonic dislocations in the Krasnoritsky fault zone, it was established that the vaults of near-fault anticlines are displaced in plan following the displacement of the faults themselves. Such displacement of vaults in productive deposits can be 0.5 km or more. Failure to take into account the displacement of structural plans with depth can be the reason for the failure of exploratory drilling in the zones of gravigenic dislocations. Therefore, in the future, it is recommended to drill obliquely directed wells in order to open the productive layers in the apical parts of the uplifts. Three uplifts have been established in the area of Muratove fault according to seismic data. The inconsistency of the shape of uplifts and the shape of faults from the position of gravigenic tectogenesis is shown. The recommendation is given for specify of structural constructions. According to the results of the comparison of geological materials and space photographs, the connection of the hydrographic elements of the valley of the Siverskyi Donets River with the Muratove fault was traced. It is assumed that the gravigenic arc-shaped faults that make up this discharge are reflected in the structure of the river valley by arc-shaped bends of ancient channels. Based on this feature, we have identified three more predictive folds with a length from 2.0 to 3.5 km. The obtained results from the prediction of new gravigenic structures are proposed to be used for the planning of seismic exploration works on the northwestern extension of the Muratove fault
