Diagnosis of the state of the reservoir system based on the entropy approach

Investigation of the energy balance of the oil fields development process by thermodynamic methods shows that the production of reservoir fluids leads to irreversible energy losses, and the use of optimal operating conditions minimizes these losses. Studies were conducted to determine the degree of order of the reservoir system, based on an analysis of the positive and negative signs of production values and changes in the entropy increment, an estimation was made of the self-organization of dynamic open systems far from the equilibrium state. Based on the concept of entropy production, an analysis was made of the main technological data of the oilfield development, which allowed us to determine the boundaries of the transient processes of the reservoir system and evaluate the estimated recoverable oil volumes. The proposed approach, taking into account the reservoir system transient processes using dynamic analysis and the concept of entropy production, allows to obtain reliable predicted values of the recoverable volumes of hydrocarbons and make reasoned decisions on choosing a strategy for oil and gas fields development.

Keywords: oil field; development; entropy production; echnological development indicators.

Investigation of the electrical conductivity of drilling fluid components for drilling sidetracks

Sidetrack drilling allows solving a number of problems, taking into account the geological features of productive horizons. Reducing the cost of equipment and consumables are also advantages of drilling sidetracks. The success of these operations is inextricably linked with the correct choice of the type of drilling fluid, which performs an important technological function, both with drilling the main borehole and maintaining the reservoir properties of deposits. In conditions of potentially unstable clay deposits, highly inhibited drilling fluids with good electrical conductivity should be highly preferred. Improving the quality of penetration by drilling of productive horizons is closely related to the incoming technological information of the drilling parameters, and at the same time, the electrical conductivity of the drilling fluid is one of the key indicators, the determination of which makes it possible to increase the efficiency and improve the technical and economic indicators of drilling. Thus, the measurement of the electrical conductivity of the drilling fluid allows you to effectively select the optimal composition of the process fluid, determine the degree of opening of productive horizons in the drilling process.

Keywords: drilling fluid; electrical conductivity; resistance; sidetrack; productive horizon.

Sensitivity analysis of oil and gas production as a result of increasing the drainage area with changes in well parameters during different completion of wells

Drilling of wells and their return to other horizons are planned in certain sequences and intervals in order to obtain maximum economic efficiency during the development and operation of hydrocarbon fields. It is important to determine the real layout of production wells, to study the relationship between them depending on various parameters. In the presented work, depending on the reservoir and well parameters, the drainage areas of horizontal wells and the interrelationships between these wells were determined, and the maximum final production of such wells was determined. The joint hydrodynamic model of the reservoir-well was used in the research. The results of the work can be used to determine the drainage areas depending on the angle of inclination of horizontal wells and to determine the relationship between them, to increase the economic efficiency of the field by reducing the additional costs of drilling unnecessary wells during field development.

Keywords: sensitivity analysis; drainage area; skin factor; hydraulic fracturing; acid treatment; formation damage; production rate.

Justification and selection of initial flow rates and depressions on the formation of horizontal wells design taking into account reservoir and filtration properties of the reservoir and the design of the horizontal section of the trunk

Normally, the starting production rate of the planned horizontal wells is based on the data acquired during the tests and surveys carried out in the vertical prospecting or exploratory wells, assigned pressure drawdowns, and the length of the horizontal wellbore section. This paper discusses the key challenges encountered when determining the productivity of the planned horizontal wells. The authors propose a method to justify and select the pressure drawdown and the length of the horizontal wellbore section when determining the well starting production rate and pressure drawdown to ensure the economic efficiency of the field development.

Keywords: horizontal well; pressure drawdown; shape of the reservoir drainage area; planned well; exploratory well.

New kill method for gas producing wells

There have been defined optimal blocking compounds in an effort to reduce the negative impact of killing fluid on the production of wells, namely the gas shows in the process of well servicing and the absorption of killing fluid. In order to increase the efficiency of killing technique for wells with gas shows, the method of well killing was developed, based on the successive injection of the gel-like mass and displacing fluid into the well. In this case, the required volume of foamgel injected in the well is determined by the height of the perforated interval of the well. Condensate or light oil is injected into the well to prevent the mixing of displacing fluid with foamgel before its full cross-linking. To retrieve the foam from the well does not need to use special compositions for its destruction. Due to the low density, the foam is easily removed from the wells by pressure drop.

Keywords: killing fluid; gas-show wells; reservoir properties; foamgel; density; displacing fluid.

Surfactant enzymes combined application for oil production intensification in Vietnam

The article shows that in the conditions of Vietnamese fields to prevent a decrease in the enzymes activity in reservoir conditions due to high salinity and temperature, it is necessary to include chelate compounds limiting the metal ions influence. The results of the EDTA-chelate experiment showed that at EDTA concentrations from 2.0 to 0.8%, the turbidity of the enzyme solution decreased during the testing time, demonstrating the positive effect of EDTA with enzymes in a salt water environment. The results of a study comparing changes in the enzyme and surfactant solutions surface tension showed that the addition of 1% stabilizer EDTA, 1% surfactant alpha-olefinsulfonate to the enzyme solution increases the activity of the system. Based on the experimental data obtained using the Modde 5.0 software, the optimal concentrations of enzyme and surfactant solutions for the minimum value of surface tension were determined. The optimal effect of the minimum surface tension value is 1.735 mN/m with components was obtained at a ratio of components enzyme:surfactant=0.477:0.3. Based on the results of optimization, the component composition of the system was obtained: microbial product of enzyme origin is 50%; Surfactant is 30%; stabilizer is 1.0%; microorganisms inhibitor is 0.5%.

Keywords: enzyme; surfactants; bottomhole formation zone; chelate compounds; surface tension.

Investigation of enzyme solutions-based complexes for oil production intensification

The article presents the laboratory studies results of enzyme-based complexes. It has been shown that to prevent a decrease in enzyme activity in reservoir conditions due to high salinity and temperature, it is necessary to include chelate compounds to limit the effect of metal ions. The results of the EDTA-chelate experiment showed that at EDTA concentrations between 2 and 0.8%, the turbidity of the enzyme solution decreased during the testing time, demonstrating the positive effect of using EDTA with enzymes in a salt water environment. On the basis of experiment the optimal enzyme solutions and surfactants concentration for the minimum surface tension value has been clarified. The optimal effect of the minimum surface tension value is 1.735 mN/m with components was obtained at the enzyme:surfactant ratio equal to 0.477:0.3. The thermal stability of the enzyme complex study results showed that the interfacial tension between the enzyme complex solution and kerosene is much less than the interfacial tension between sea water and kerosene (21.75 mN/m), and this is proof of the enzyme complex thermal stability at the reservoir temperature.

Keywords: enzyme solution; thermal stability; wettability; oil recovery stimulation; surfactant.

Experimental studies of oil displacement ability using enzyme solutions based complexes on a reservoir model

The article presents the laboratory tests results of enzyme solutions application on the model of the White Tiger Miocene deposits. It has been established that the enzyme solutions application makes it possible to increase the oil displacement efficiency in the range of 7.23–10.59%. The values variation is associated with different core samples characteristics in terms of porosity, permeability, initial oil saturation, and in terms of lithological composition as well. After enzyme solution treatment the differential pressure decreases, which indicates a change in the oil with oil-bearing rock wettability.

Keywords: Enzyme solution; reservoir model; oil displacement efficiency; wettability; bottomhole formation zone.

On the stress state of an elastic hollow ball during liquid filtration through its wall

When determining the stress state of an elastic hollow ball during liquid filtration through its wall, it is necessary to solve the problem of stresses for the case of liquid filtration towards the center of the ball with a decrease in pressure in its cavity (χ = -1). A change in the sign of the filtration potential leads to a change in the tangential stresses on the borehole wall to a value equal to three times the reservoir pressure drawdown (in this case, the radial stresses are equal to zero). This explains the negative effect of well shutdowns, and even more so the change in the direction of the filtration flow in the near-wellbore part of the formation, on the stability of the walls of wells, the operation of which is complicated by formation sanding. Thus, the maximum difference in the main normal stresses is observed on the borehole wall, therefore, in order to prevent the destruction of the formation near the bottom, the necessary condition is that the strength properties of the rocks correspond to the stresses acting in this zone. When operating wells prone to plugging, it is necessary to limit the reservoir pressure drawdown to the maximum allowable value, when the material of the near-filter zone is in an elastic state throughout the volume.

Keywords: stress; state; casing; string; well; integration; equations.

Inhibitor for nitrogen-containing hardness deposition based on ethanolammonium phosphates

The inhibitors based on nano-containing compositions (NCC) have been developed for hardness deposition. A method for developing an inhibitor for saline deposits involves the interaction of amino alcohols with orthophosphoric acid by adding nanoparticles and further diluting them with water to form a 2% solution. It was found out that the inhibitors developed by NSC for saline deposits at a flow rate of 20-30 mg/l are highly effective for controlling the deposits of calcium and magnesium sulfate in the produced water model. The controlling effect of inhibition in these cases is 86.3-99.4%.

Keywords: inhibitor; amino-containing compound; orthophosphoric acid; hardness deposition; nanoparticles.

Development of the diasgnostic method for determination of density of «water-oil-sand» type mixtures

In this article has been proposed empirical dependencies for the direct determination – without mathematical calculations or experimental measurements of density of “water-oil-sand” type rheological complex mixtures resulting from arbitrary mixing of oil with water and sand in the processes of production, collection and transportation of well products. Also, based on the application of «Colour characteristics», a new diagnostic method that allows to explain the dependence of density, which is one of the main quality indicators of heterogeneous liquids transported by pipeline, on watering and temperature factors, as well as the concentration of filler element, leads to new trivial solutions in the processes of production and transportation. Given its practical significance and expediency for use in hydraulic calculations, its application prospects have been commented.

Keywords: granular filler; dispersed systems; heterogeneous liquids; suspension; density factor; empirical dependence.

Improving the accuracy of temperature measurements in heat supply systems

The constant rise in energy prices leads to an increase in the cost of thermal energy, which is used in heat supply systems for industrial and residential premises. Therefore, improving the accuracy of measuring the heat supplied to consumers is an urgent task. Instrumental metering of heat energy requires regular measurement of the temperature of the coolant in the pipelines of the heat supply system. There is an opinion that all the problems of measuring temperature when accounting for thermal energy have been solved. However, this is not the case. The analysis shows that the systematic component of the error in measuring the temperature and the temperature difference between the supply and return pipelines, especially in conditions of small values of the difference, makes a significant contribution to the instrumental error of accounting for thermal energy. The article discusses solutions to minimize these errors in temperature measurement, taking into account the consumption of thermal energy.

Keywords: temperature measurements; measurement error; thermal energy; thermodynamics; metrology.

A new method of designing a conversing mechanism of a hinged four-link of a pumping machine

The transforming mechanism of pumping units is a four-link articulated mechanism, made according to symmetrical and asymmetric kinematic schemes. With a symmetrical scheme, the center of rotation of the crank is on a straight line passing through the points corresponding to the extreme positions of the connecting rod and balancer articulation. All other cases correspond to the asymmetric scheme. Currently, in accordance with the existing methodology for designing a converting mechanism of a symmetrical circuit, the kinematic ratios r/k and r/l are used as initial data - the ratio of the crank radius to the length, respectively, of the rear arm of the balance bar and connecting rod. It is considered more preferable and practical to design a mechanism according to predetermined output parameters. As a result, we find that the overall dimensions of the converting mechanism of domestic pumping units of a symmetrical scheme (length by 45…60%, and height - 25…30%) are less than those of foreign pumping units of an asymmetric scheme. The developed technique allows to compare the technical and operational indicators of pumping units made according to various kinematic schemes.

Keywords: connecting rod; balancer; cranks; traverse; radius; mechanism.

Determination of the dimensions of the differential mining rent in the oil industry of Azerbaijan to optimize the tax burden

In modern conditions, the definition of the amount of differential mountain rent on the macro level (the oilproducing company, the industry) should allow optimizing the tax system in oil production by determining the maximum limits of seizure. Оn the basis of a methodology based on the submissions of political economy, on a differential mining at the level of production facility as a difference between the closing costs, calculated on the production volume and its actual costs, a methodology was proposed by the method of differential mountain rent on the macro level as The amounts of the dimensions of the specified rental income on individual production facilities (well, deposit). On the basis of the proposed methodology, the work was calculated by differential mining rates on oil production of Azerbaijan in 2020 according to state statistics. The calculation and subsequent seizure of the amount of differential mountain rent in the state's income will allow further taxation of oil production can be carried out at unites rates or differentiated by the natural and transport component (Rent of location), as a tax on mineral mining (NPPI).

Keywords: differential mountain rent; limit costs; actual costs; production facility; production volume; rent on macro levels.
