70 years of petroleum exploration history – from the Shugurovskoye deposit to the unique multilayered Romashkinskoye field

Key words: reserves, production, wells, geological exploration, locally producing intervals.

The article considers the history of exploration and development of the unique Romashkinskoye oil field from 1933 until the present day. At the present stage, geological exploration operations for further increment of oil reserves should focus, primarily, on prospecting small oil deposits confined to frontier locally producing intervals. Moreover, a particular emphasis is given to the studies of crystalline basement, fracture system and unconsolidated zones in the sedimentary cover.

Estimation of fracture system parameters for reservoir rocks in the Republic of Tatarstan based on oriented core analysis and downhole imaging tool data

Key words: carbonate reservoir, fracture system, oriented core, micro-conductivity imaging tool (MCI).

Carbonate reservoirs are, for the most part, naturally fractured which creates additional structural heterogeneity and has a significant effect on oil recovery pattern. Fracture system parameters are determined using direct methods (core material analysis) and by open-hole well logging. Only combined application of modern well logging and core analysis techniques can ensure a reliable characterization of such reservoirs. The resulting data will enable a detailed description of carbonate reservoir structure and will be considered while drilling new wells and reservoir development planning.

The influence of heterogeneity of a clay component material composition on a reservoir petrophysical and filtration characteristics

Key words: mineral composition, clay minerals, water retention factor, effective porosity, permeability.

Quantitative relation is shown to exist between mineral composition of a clay component of rock and parameters of the petrophysical model of a polymineral terrigenous reservoir. A significant increase in confidence of permeability estimation based on well log data is achieved using effective porosity and a parameter accounting for influence of mineral composition of rock cement. An approach to parameter estimation for low-permeability zones with values below cut-offs is proposed.

Selection of the design for water shut-off jobs in the software system RN-REST

Key words: water shut-off jobs, WSO design, workovers.

The process of planning water shut-off (WSO) jobs in oil producers is based on the selection of optimum WSO design that is characterized by the lowest water cut after the job along with maximum incremental oil rate. A software product that makes possible the evaluation of different WSO jobs effectiveness for vertical wells in sandstone reservoirs is presented in the paper along with the current directions of its development. WSO Design modulus is based on the software system RN-REST and it is currently implemented in producing affiliates of Oil Company Rosneft. It covers many types of workovers that include isolation materials and allows loading all the data necessary for calculation in automatic mode. These features make the modulus a convenient instrument to create a design of WSO jobs on Oil Company Rosneft oilfields.

Assessment of line of corrosion processes development in existing wells by geophysical methods

Key words: corrosion interval, the line of corrosion development, method of research, measuring of thickness, geophysical methods.

Geophysical methods, included in the system for the study of the technical condition of the flow string of wells, does not allow to assess of the line of corrosion processes development, that is necessary for the design of measures for strings protection from the corrosion. The method of research of line of corrosion development is prepared. The results of its testing in wells of Surgutneftegas OJSC fields are given. The results of several stages of the conducted research allowed to adjust the method, to understand the causes of corrosion processes appearance and to reveal the most corrosion dangerous intervals in wells of various purposes.

Some results of research the strong electric field effect on the oil stabilization

Key words: oil, stabilization, separation, vapor pressure, electric fields.

The results of laboratory studies of the process of separation of gas from oil under the effect of a strong electrostatic field are given. It is shown that the effect of an electric field on this process is equivalent to a significant increase in oil temperature or reducing the external pressure. A practical use of the obtained results, including the design of the oil fields construction, is suggested.

Multiple reuse in closed cycle of surfactant alkaline solution in demercaptanization process

Keywords: hydrocarbons, mercaptanes, alkaline extraction, surfactants.

Possibility of multiple reuse of surfactant alkaline solution in demercaptanization process has been studied. It was found that use of surfactant alkaline solution greatly improves mercaptane extraction ratio and allows it is multiple reuse in closed cycle hydrocarbon demercaptanization. In case of single injection of surfactant in alkaline solution, that solution has retained it’s activity in many cycles without addition of fresh portions of surfactant and provided permanently high mercaptane extraction efficiency from light hydrocarbons.
