Economic assessment of the strategy of oil-gas-condensate deposits integrated development in Tomsk region

In order to involve into development the reserves of non-developed fields, located in the same area (Tomsk region), we propose the consolidation of license holders’ efforts. Only such approach allows to bring on development small (uneconomic) reservoirs, exclude duplication of design and construction works, which can lead to unjustified investments and capital costs. Accepting one single strategy, there is a possibility of share holding in field construction on mutually beneficial conditions for all concerned parties.

Additional possibilities for Tatneft assets’ hydrocarbon potential increment

Possibilities for commercial oil reserves increase in Tatneft fields are analyzed due to geologic exploration and re-estimation of reserves. At the present stage of geologic exploration a considerable part of possible reserves and contingent resources are considered to be hard to recover. Insignificant reserves and complex geology of reservoirs result in considerable increase of small oil fields’ prospecting and development costs.

On the oil displacement from the cavernous fractured reservoirs at nonlinear filtration regime

The features of fluid filtration in cavernous fractured reservoirs are considered. It is shown that very small volumes of reservoir as compared to the total drainage area in the near well zones are characterized by nonlinear filtration regime. It is concluded that the processes of oil displacement from cavernous fractured reservoirs in real well-reservoir systems with sufficient accuracy can be characterized (and evaluated) on the basis of dependencies, obtained under the assumption of a linear filtration law observance. At the same time the deviations from Darcy's law must be considered at calculation of filtration resistance and wells interaction.

The complex approach to the choice of the optimum acid composition for well stimulation in carbonate

It is noted that at a choice of the technology of wells acid stimulation in carbonate reservoir it is necessary to be guided by an integrated approach to the reagents and design. It is shown that taking into account the properties of acidic compounds for specific geological and physical conditions increases the efficiency of the well bottom zone stimulation due to a larger radius of influence, preventing the formation of insoluble compounds, bridging the pore space of this zone. The results of determining the kinetic parameters, characterizing the rate of acid composition reaction with oil- and water-saturated rock samples, are given.

Filtration regularities (capillary impregnation and filtration) of oil and petroleum products from soil surface deep into a soil profile in the natural conditions Have been researched. It is shown the migration of oil and petroleum products depends on their nature (density, viscosity, content of active components), as well as humidity of superficial soil layer and its mechanical structure. Depending on these parameters, the depth of infiltration of oil and petroleum products into soil changes in a wide interval.
