Physics of gravitational processes as a key to understanding the properties of Achimov deposits

The article is devoted to the development of a methodology for predicting the properties of Achimov reservoirs based on cause-and-effect relationships such as the source of shelf sedimentary material, the geometry of clinoforms and the distance of alluvial fans to the slope. The technique was developed on the basis of physical laws, namely the conditions of disturbance of the gravitational equilibrium of sediments on the shelf edge – the moment of the beginning of the removal of sedimentary material and the process of cone formation caused by the deposition (braking) of sediments on the bottom of the basin. The methodology includes two stages for step-by-step theoretical justification and ease of understanding. At the first stage, the problem of disturbing the gravitational equilibrium of shelf sediments depending on the geometry of the clinoforms is solved. At the second stage, the problem of dependence of the distance of the blades on the slope and the properties of promising objects is considered. Based on theoretical concepts, the main conclusions about the dependence of the characteristics of alluvial fans (properties and volume of sandstone) on the geometric parameters of clinoforms and on the distance to the slope are outlined, and a complex parameter characterizing the properties of promising objects is derived. The methodology developed by the author makes it possible to predict, compare and rank Achimov objects according to their prospects both within one formation and as a whole in one or several fields.
