Bashneft is a Russian oil company formed by the transfer of the oil related assets of the Soviet oil ministry in Bashkortostan to the regional government of the Republic of Bashkortostan by Boris Yeltsin. It was then privatized during 2002-3 by Murtaza Rakhimov, the boss of Bashkortostan, a crony of Yeltsin's, with a controlling interest in Bashkir Capital, a holding company controlled by Rakhimov's son, Ural Rakhimov. In 2009 a controlling interest in Bashneft was acquired for $2 billion by Vladimir P. Yevtushenkov and placed in his holding company, Sistema, but in July 2014 he was jailed and 72% of Sistema's interest in Bashnoft seized by the Russian government. Following seizure of the company in December 2014 Yevtushenkov was released from jail, "charges not proven," but Ural Rakhimov was reported to have fled the country. It is one of the largest producer of oil products in the country. The company operates 140 oil and natural gas fields in Russia and has an annual oil production of 16 million tonnes. Bashneft owns three oil refineries located in Ufa with a combined capacity of 820,000 bbl/d and 100 petrol stations. Wikipedia.

This paper examines the cyclic structure of productive carbonate sediments bearing in mind the ramp depositional model. Different lithotypes depending on the intensity of the secondary dolomitization identified in the sedimentary cyclites. Low dolomitic lithotypes retain primary sedimentary features and meet the standard Flugel microfacies. The layered structure of the carbonate strata due to the manifestation of the high-frequency sedimentation cycles is shown with the new data.

The present study considered the problem of the interface motion between two immiscible liquids. The solution of this problem for applications of flow diverter technology would be evaluation basis of the hydrodynamic medium properties changing over time, such as the fluid mobility, the saturation, pressure distribution, mean resistance and conductivity. The results were obtained for two types of filtration: radial and linear one. First case describes the physics for liquids flowing to well galleries, second-the process of contour contraction or a motion into the formation. Analytical solution for the radial case was derived for the first time. A method to assess the degree of injectivity profile smoothing after the flow diverter technologies.

In 2012 Bashneft JSOC won the exploration, production and development service contract for Block 12, Iraq. The paper describes the methodology applied for assessing the probability of an oil discovery on this block, as well as probabilistic estimates of the possible reserves volume. The combined use of the Monte Carlo method is described, both for the volumetric parameters that determine the possible range of the recoverable reserves and for the probability factors that determine the chance of geological success for each potentially productive formation. Special attention is given to the interdependency of the probability factors and the correct handling of its effect on potential oil reservoirs in different formations within a single geological structure (trap) and on oil reservoirs within the same formation but in different traps.
