High Viscosity Oil

The method of Arps fall curve as an effective method that allows reliable and efficient prediction of well flow, a necessary parameter for optimal and correct choice of well operation is considered in the article. Forecasting the flow rate of wells in fields with high-viscosity oil stocks is one of the most difficult tasks in the development of oil fields. It is proved that the use of the Arps method simplifies this task, as it gives the correct results quickly and easily. The importance of the choice of well operation methods is analyzed. It has been proven that the analysis of reduced production is a means of identifying productivity problems in wells to assess their future productivity and expected service life. The use of the Harmony Enterprise platform is designed to analyze the performance of oil and gas wells and inventory assessment, to create common corporate work processes, use technical knowledge and exchange interpretations, which allows you to identify promising assets, evaluation and development strategy. The results of this work are very important and necessary for further research and analysis of the fall in production and analysis of the well.

The article offers a method to solve Buckley-Leverett’s problem, taking into account the nonlinear dependence of the filtration rate of viscoplastic oil on the pressure gradient. This method is based on the transformation of the fractional flow function by introducing in the theory of water drive the equations reflecting the rheological features of the oil flow. The resulting model allows us to quantify the influence of rheological factors on the completeness of the water-oil displacement and to calculate the performance, taking into account the component composition of the hydrocarbon phases. Taking the Samara Region oil fields as an example, the article shows that the quality of design is unsatisfactory when the bundled software being used does not take into account specific non-Newtonian properties of the high-viscosity oil.

The Republic

The Republic of Tatarstan has accumulated vast experience in the exploration and development of oil fields of various ranks – from small and smallest to giant and supergiant. Approaches for the rational development of various groups and categories of deposits have been found. The most effective methods of prospecting, exploration and additional exploration of oil fields, the most advanced hydrodynamic methods of developing fields with active and hard-to-recover reserves, including those at the late and post-late stages of development, have been worked out. Methods of enhanced oil recovery have found wide application for various geological and physical conditions, including the extraction of residual reserves from long-term exploited fields. A great deal of experience has been accumulated in the development of complex small fields with hard-to-recover oil reserves. Research work is underway to find effective methods for the development of unconventional oil deposits (high-viscosity, ultra-high-viscosity oils and natural bitumen, in shale and similar deposits), to study the phenomenon of replenishment of sedimentary cover deposits with deep hydrocarbons through the crystalline basement. This experience of advanced development of the republic helps in the formation of the principles of a new paradigm for the development of the oil and gas industry.

Cyclic Injection

This article discusses a digital geological model, the transfer of borehole data to the geological grid, and the modeling of the technology of alternating steam and water injection. Alternating injection involves the cyclic injection of steam and water into an injection well in high-viscosity oil fields. The essence of this technology is that during the steam injection for 2-4 months, the formation warms up, leading to a decrease in viscosity and an increase in oil mobility. Then comes the period of water injection, during which the production of already warmed oil continues and the formation pressure is maintained. For digital geological modeling, the following data were collected, processed and prepared: a list of wells that open the object of modeling, coordinates of wellheads, well altitudinal data, inclinometry of well trajectories, GМS data on wells, analysis of wells drilled with core sampling, and digitized seismic data (structural surfaces on the roof of stratigraphic horizons, parameter maps, contact surfaces, faults, structural maps on the roof of target horizons with faults, isochron maps, velocity maps).

While choosing an optimal field development strategy it is necessary to take into account the possible effects of oil structural-mechanical qualities. The presented methods allow estimating the effect of structural-mechanical qualities of the production of oil with high levels of asphaltene and tarry substances. After completing all calculations and designing, a parameter set is created for optimal depletion mechanisms of the production of nonlinear high-viscosity non-Newtonian oil.

High Viscosity Oil

Significance Facing a budget gap formerly filled by oil and gas, the Russian government is proposing new taxes for the mining, oil and tobacco industries. It is considering proposals to triple the mineral extraction tax on metals, fertilisers and high-viscosity oil producers. Impacts The new taxes could bring as much as USD4.5bn a year in additional budget revenues and will relieve pressure to borrow domestically. A tax shift is seen as more sustainable to drawing on the sovereign wealth fund, which will be kept for emergencies. The government also intends to raise revenues by increasing excise tax on cigarettes by 20% in next year's budget.
