Almetyevskaya Square is one of the central squares of the Romashkinsky oil field. It is confined to the west-central part of the South Tatar arch. From the west, it is bounded by the Altunino-Shunak trough, which separates the square from the Novo–Elkhovskaya structure. The main operational object of the area is the productive deposits of the Kynovsky (D0) and Pashysky (D1) horizons to the Lower Fran sublayer of the Upper Devonian, represented by the interlayer of sandy, sandy–siltstone and mudstone rocks. The correlation of the layers of the Pashian horizon is carried out using the main reference points "upper limestone" and "Mullin clays", which lie, respectively, in the roof and plantar parts of the horizon and an additional reference point "mudstone" in the middle part of the horizon.
Keywords: productive deposits of horizons, correlation of layers, reservoirs, thickness of clay sections, coefficients of sandiness and dissection
