Prospects of oil-and-gas content of the deep-shipped deposits of the Verkhnepechorsky hollow by data basin modeling

DOI:

Key words: Vuktylskoye gas&condensate field, Verkhnepecherskaja depression, oil-bearing, modeling of sedimentary basins, the model of oil and gas generation.

The article is devoted to the problem of oil and gas deep horizons Verhnepecherskij basin Ural foredeep. Due to the deep position of the oil-gas complexes, complicating exploration in this area, natural systems basin modeling was implemented. This article describes the results of 1D simulation using the software package Genex of well Vuktylskaya-58, who revealed the deep horizons of the sedimentary cover. The authors made several conclusions about the possibility of generation of gases and condensates, which could ensure the formation of deposits not only in the deeper horizons, but also large deposits in the overlying sediments, the selected periods of generation and accumulation of hydrocarbons, determined the position of the main zone of oil formation according to wells, and the lower limit of the existence of oil.

Mathematical and information support of decision making during the optimization of the formulas of magnesia plugging materials for boring casings cementing in the oil and gas wells

DOI:

Key words: deep well, dry magnesia cement mix, composition optimization, regression models, case study method.

The production of the dry magnesia cement mixes, intended for the qualitative cementing of the boring cases, overlapping the deposits of water-soluble salts in the oil and gas wells, is labor-consuming process. By this the need for the optimization of their compositions taking into account the chemical activity of the magnesia binding base, features of the mining-geological and engineering-technical conditions of the construction of each concrete well, is caused. As the method, making it possible to operationally optimize the process of the new formula choice, the case study method is selected. The method in question is based on the use of cumulative data on the previously optimized formulas of magnesia plugging materials. The applicability of the solutions, obtained with the aid of the case study method, is checked with the aid of the regression models, created with the use of the three-factor planned experiment, and by conducting control laboratory investigations of the selected according to the case study method formula of dry plugging mixture, prepared under the plant conditions. As a result the possibility of applying the selected method for the operational optimization of formulas at the production of dry magnesia cement mixes is proven.

Effectiveness of acidizing in Bashkir deposits of Perm Region

DOI:

Key words: oil reservoir, well, productivity index, acidizing, production, bottom hole pressure.

This paper presents the results of applying the two acid solutions for stimulation of oil wells in the Bashkir sediment rocks in the fields of Perm region. The influence of technological and geo-physical parameters of the layers on the success of the acid treatments is estimated by comparing the rates of well productivity before and after acid treatment. It is observed that after the acid treatment, water content in well products increases in the majority of cases. With the growing volume of acid solution pumped per unit of effective oil acid, performance impact is increasing. The average depth of penetration of the acid solution in the bottom zone of 0.5 m. Overall it was obtained that conducted acid treatment stimulation of the oil wells was effective and provided the lasting effects on the well productivity. The rate of success is higher for the wells with low reservoir pressure.

DOI:

Key words: Arctic shelf, Eastern Siberia, shale hydrocarbons, hard-to-recover reserves, Moscow sedimentary basin.

The problem of limited hydrocarbon resources trained every year it becomes more obvious. Against the background of known proposals to address this problem are bypassed proposals for study and additional exploration of vast areas for various reasons remained unexplored. Examples of these areas include Moscow sedimentary basin. A special feature of the territory is the presence in the sediment Devonian traps as crystalline solids, in terms of covering a huge area. Thereby generating conditions for the formation of hydrocarbon traps in areas previously recognized unpromising. The author proposes some ways to greatly alleviate the problem of lack of hydrocarbon resources in the shortest possible time and with minimum cost.

An integrated experimental approach to determination of clogging kinetics of porous media

DOI:

Key words: porous medium; near-wellbore zone; transport of solids; drill mud; internal filter-cake.

The authors present a new technique for estimating of kinetic parameters of internal filter-cake buildup by combining laboratory mud-filtration experiments with a profile of invaded mud components reconstructed by X-ray microcomputed tomography, image processing of a cleaved sample, and ultrasonic wave scanning. We include examples of reconstructed profiles of invaded mud components (solid particles and bentonite clay) as well as the procedure of determining of internal filter-cake parameters. Using obtained profiles we demonstrate that value of “critical porosity” when all mud particles stop to penetrate into porous medium and depost at the sandface, forming the external filter-cake. In the case of heterogeneous rock (limestone) the group of high-conductive pores is visualized.

Developed experimental techniques allow obtain the profile of mud components in core sample, determine the parameters of clogging kinetic and, then, calculate the mud components and permeability profiles in the near-wellbore zone.

DOI:

Key words: mud losses, clogging, internal and external mud cake, perforation, cleanup of near-wellbore zone.

The processes that occur during the well drilling and completion have significant and often irreversible effects on the properties of near-wellbore zone. Sensitivity study of the characteristics of mud invasion, well cleanup and production processes is carried out to the properties of reservoir, external and internal mud cake and perforation length. Sensitivity of dynamics of external mud cake buildup to the rate of mud circulation in wellbore is also analyzed. The characteristics of mud invasion significantly depend on the reservoir mobility, solids concentration and circulation.

The accounting of the mechanism of heat conductivity in the hydrodynamic models of the skilled site of yaregsky of the field

DOI:

Key words: field, high-viscosity oil, hydrodynamic modeling, heat conductivity, development indicators.

For rational, science-based heavy oil exploitation the creation of simulation models requires using a variety of modern software products. Often the accuracy of modeling of technological processes is influenced by shortcomings of simulators. The simulator of STARS doesn't consider heat arriving in layer at the expense of heat conductivity through a lateral wall of a well. In this connection, the calculation procedure and the accounting of additional quantity of heat on the basis of statistical data is developed. The filtrational model of a site OPU-3 bis Yaregskoye oil field taking into account the heat conductivity mechanism is created; technological indicators OPU-3 bis by two options are predicted; extent of influence of the additional mechanism of warming up on technological indicators of development is estimated. The mechanism of warming up of productive layer due to heat conductivity has essential impact on final coefficient of oil recovery that is caused by the additional useful energy brought in layer by development Yaregskoye heavy oil field.

System-integrative approach to automation of the oil and gas fields design and development control

DOI:

Key words: geologic-technological model, artificial intelligence, wells process optimization.

At present, the important issue is to develop a system of effective management and monitoring of the oil and gas field, for which have been used hydrodynamic model. In this paper, the basic steps of creating a permanent geological and technological model (PDGTM) and the analysis of the data needed for its construction are presented. On the basis of PDGM and neural network models to improve the system of automatic control and monitoring of oil and gas development is proposed the system-integrated approach that takes into account the basic system principles of the oil and gas development design and control processes. To ensure matching of recovery rates and injection fluid it is proposed local automation and control system of oil production well operation modes. On this basis, the optimization solutions modeling method is functionally extended, providing options to optimize modeling and decision making in the control and management of oil and gas development system.

Ecologically based sediment quality criteria of the oil content for freshwater ecosystems on example of Kuibishev water reservoir

DOI:

Key words: oil products, sediment quality criteria, bioassay.

This article presents the criteria of sediment quality assessment for oil content according the integrated approach which based on chemical, ecological and toxicological data derived from a TRIAD monitoring network. The ecological criteria (the lowest effect level and the severe effect level) were calculated for oil content in sediments of Kuibyshev water reservoir on the base of benthos taxa occurrence. For the toxicological data, the threshold effect level and probable effect level were calculated, based on the results of the toxicological acute pore water and solid phase tests. The sediment quality guideline (49 mg/kg) is as a consensus value of the lowest effect level and threshold effect level. Presented criteria can be used for ecological risk assessment for benthic community in condition of cruel oil contamination.
