Applied aspects of geochemical parameters of oil


The given paper provides data on the fingerprints of Azerbaijani oils using biomarkers (GC/MS) and microelement composition (ICP/MS), as well as the main geochemical parameters of oil, such as CPI, Ki, QI, ITC, Ts/Tm, Pr/Ph, etc., and data on correlation dependencies of geochemical parameters on the horizon at particular oilfield. Characterization of oil accumulations belonging to the mid-Pliocene in the Caspian Sea in terms of hydrocarbons - biomarkers and geochemical parameters makes it possible to predict the composition and the predominant type of oil in the field with similar geological structure.

Keywords: oil biomarkers; chromatographymass spectrometry; mass spectrometry with inductively coupled plasma; oil fingerprint.

Geodynamic prerequisites and reflection of signs of fluid migration in hydrogeochemical indicators of formation water in the Bukhara-Khiva region


The article describes the results of a study of changes in the composition and hydrogeochemical parameters of individual areas and fields of the Bukhara-Khiva region based on well materials. Vertical zonality of hydrogeochemical parameters associated with deep fluid flow and heat and mass transfer is noted. The manifestation of tectonodynamic conditions in the Mesozoic-Cenozoic history of the region, which served as a prerequisite for the formation of weakened zones (channels of deep heat and mass transfer) in the field of tensile stresses for the vertical migration of fluids and juvenile gases, is noted. A hydrogeological criterion for identifying zones of deep heat and mass transfer and vertical fluid migration is proposed.

Keywords: wells; oil and gas; formation waters; fluids; hydrogeochemical indicators of formation waters; heat and mass transfer.

Mineralogy, geochemistry and paleoweathering characteristics of Paleogene-Miocene oil shales in Azerbaijan


The Paleogene-Miocene oil shales studied in the paper were taken from the outcrops and ejecta of mud volcanoes in Shamakhi-Gobustan and Absheron regions. The geological age, mineralogy, and chemical composition of the samples were studied by analytical investigations. Minerals found oil shales were described in detail in the relevant categories. Some appropriate classifications were made in connection with the chemical composition of samples. The indices such as CIA, CIW, PIA, "RR = SiO2/Al2O3" - chemical weathering index, the diagrams like "(Al2O - K2O) – CaO – Na2O", "A-CN-K", and also reflecting mobility characteristics of elements, and estimates on large-ion lithophile elements were used to study the paleoweathering characteristics.

Keywords: oil shale; geochemistry; mineral; paleoweathering.

A study of the structure and strength properties of the WC–Co drill insert with different CrB2 content sintered by vacuum hot pressing


The optimal ratios of the components of the WC–Co‒CrB2 system have been established, at which a finely dispersed structure is formed with a simultaneous improvement in physical and mechanical properties. It is shown that the introduction of CrB2 (in concentration CCrB2 = 4% wt) leads to a twofold increase in fracture toughness (from KIc = 4.4 MPa ∙ m1/2 to KIc = 9.8 MPa ∙ m1/2) with a slight decrease hardness (from H = 15.1 to 13.9 GPa), as well as to an increase in the ultimate bending (from σ = 2000 to 2500 MPa) and compression (from σ = 5300 to 6000 MPa) strength of sintered composite specimens. Creation of the WC–Co‒CrB2 composite materials with improved mechanical and operational properties is essential for optimizing the designs of drilling tools for various technological purposes, increasing their reliability, energy saving, and improving operational properties.

Keywords: composite; composition; concentration; structure; hardness; fracture toughness.

Diagnosing multiphase flow regime in multilayered reservoir by distributed temperature sensor measurements


The article discusses the possibility of diagnosing the multiphase flow regime in the multilayered reservoir by using DTS (distributed temperature sensing) data. The analysis of the theoretical and actual curves of temperature build up and drawdown, corresponding to the main modes of multiphase flow of formation fluids are given in this article. The possibility of diagnosis of the multiphase flow regime is found based on analysis and interpretation of the characteristics of temperature build-up and drawdown in different intervals of the reservoir at the start of the well or shut in, or by changing opening degree of the choke. The possibility of diagnosing water breakthrough (WBT) intervals, based on the analysis of the changes in temperature curves according to the DTS is shown. For a more detailed analysis and interpretation of temperature change curves in the wells more frequent DTS measurements are required. It is necessary to conduct a comparative analysis of the dynamics of the temperature and pressure redistribution in the productive zone of the well, with the results of geophysical logging, production logging, taking samples of reservoir fluids from different zones of productive layers in the multilayered reservoir, moisture metering, hydrometry and others.

Keywords: well; monitoring; multilayer reservoir; temperature profile; distributed temperature sensor; multiphase flow regime.

Numerical method for determining the coefficient of hydraulic resistance two-phase flow in a gas lift well


The process of stationary movement of a gas-liquid mixture in the lifting pipe of a gas-lift well is considered. To describe this two-phase flow, a mathematical model is proposed that includes the equation of flow motion and the continuity equation for each phase. The presented model is transformed to a single nonlinear ordinary differential equation with respect to pressure. Within the framework of the obtained model, the task is set to determine the hydraulic resistance coefficient of a two-phase flow according to an additionally specified condition with respect to pressure. An additional condition, presented in the form of a nonlinear algebraic equation, is transformed into an ordinary differential equation with respect to an unknown coefficient of hydraulic resistance by applying the method of differentiation by parameter. The solution of the resulting Cauchy problem is determined by the finite difference method. Based on the proposed computational algorithm, numerical experiments were carried out for model data.

Keywords: gas lift; two-phase flow; hydraulic resistance coefficient; parameter differentiation method; finite difference method.

New combined well design to protect electric submersible pump from sand flow


The paper presents a new well construction in order to eliminate the unpleasant complications associated with the appearance of sand flow in the Electric Submersible Pumps (ESP), which is widely used in oil wells in the final stage of reservoir development. The new design is based on the combination of ESP with a Mixer based on the principle of ejector and centrifugal. The combined well construction limits the ESP to be in contact with the sand flow and prevents potential erosion and other complications. The design was modeled and tested in the laboratory condition.

Keywords: field; layer; pump; well construction; sand production; sand separator.

Features of the impact of high-amplitude short pulses of hydrodynamic pressure on perforation channels


The features of the impact of high-amplitude short pressure pulses on perforation channels in the bottomhole zone of the well are analyzed. It is shown that in the channels formed in the rock with the use of cumulative perforation and having a conical shape, there is an increase in pressure pulses when a certain condition is fulfilled, which limits the duration of this pulse. It has been established that in the negative phase of the pressure pulse, destruction of the cured rock layers adjacent to the walls of the perforation channel can occur, which improves the filtration-capacitive properties of the bottomhole zone of the well. It is shown that when using explosive charges of low mass, pressure pulses are formed with parameters similar to those of pulses generated by electric discharges in the wellbore. To apply the technology of explosive action with low-mass charges on the bottomhole zone, the standard equipment used for cumulative perforation of wells can be used. A method for screening pressure pulses is proposed, which increases the effectiveness of their impact on the bottomhole zone of the well and simultaneously reduces the excessive load on the casing pipes above the productive formation.

Keywords: bottomhole zone of a well; perforation channels; electric discharge impact; low-mass charges; reflecting screen.

On the possibility of regulation of rheophysical properties multicomponent mixtures based on rheotechnology


The article deals with the regulation of the rheophysical properties of multicomponent mixtures on the basis of the purposeful application of a new direction in science-rheotechnology. The data of rotoviscometry once again confirmed that the sequence of mixing the constituent components of the oil-water-sand mixture directly affects the rheology of the newly formed systems. The method of changing the order of entering the constituent components shows the prospects for increasing the efficiency of the processes of extraction, collection and transport of oils and their mixtures based on the creation of new rheological methods based on the regulation of the rheophysical properties of the heterophase systems under consideration.

Keywords: constituent components of the mixture; rheology; structural viscosity; anomalous index; graph-analytical method.

Enhanced oil recovery in water-flooded and hard  to recover reservoirs


The article is devoted to enhanced oil recovery (EOR) by displacement of residual oil with chemical agents in hard to recover reservoirs. SOCAR Oil Refinery alkaline waste (AW) is used as chemical product for EOR in the researches. Researches were carried out on pure AW and its solutions in different densities. 10% solution of water with AW decreases interfacial tension from 27 mN/m to 1.0 mN/m. PH value respectively increases from 7.5 to 9.5. Then, the researches were performed in simulated reservoir model. Primarly, the interlayer was created from solutions with AW in different densities, and then the displacement was carried out. Final oil recovery rate was 0.453 during oil displacement without AW. This ratio was respectively 0.54, 0.571 and 0.573 during displacement of oil with 5%, 10%, 15% solutions of AW. EOR with AW solution was carried out in QLD4 horizon in Goshanohur area of Balakhany-Sabunchu-Ramana oil field. 2500 tons incremental oil was produced.

Keywords: enhanced oil recovery; residual oil; oil displacement; oil field; well.

Hydrogasdynamic modeling of optimization of underground gas storage development


On the basis of large-scale gas-hydrodynamic balance models, the problem of optimizing the cyclic development of underground gas storage (UGS) facilities has been formulated and solved. An algorithm has been developed that allows optimal control of the UGS development process, taking into account the limitations on the flow rates of certain wells. For its implementation, a specific model structure of the Kalmaz UGS facility was selected. It is shown that optimal regulation of the values of flow rates and depressions of wells ensures minimal flooding of well products during the extraction of total gas, the values of reception and repression of wells ensure maximum removal of the gas-water boundary from the bottom of the well during the injection of total gas.

Keywords: optimization; underground gas storage; extraction; injection; flow rate; depression; repression.

Comparative analysis of the geopolymer and Portland cement application as plugging material under conditions of incomplete displacement of drilling mud from the annulus


Portland cement is traditionally used in cementing of oil and gas wells. However, Portland cement has a number of shortcomings. The most important of these are the formation of microannuli between the cement plug and the rock or casing, as well as the formation of cracks and permeable channels in the cement matrix. Recent research shows that geopolymer can be a perspective alternate to portlandcement by overcoming beforementioned issues. The article comparatively analyzes the changes in the parameters of plugging materials containing geopolymer and Portland cement while contamination with water-based drilling mud. The results show that geopolymerbased solutions are more resistant to contamination with water-based drilling mud than Portland cement-based solutions. Thus, mixing Portland cement slurry with water-based drilling mud increases its viscosity and fluid loss, and sharply reduces its compressive strength. However, when a geopolymer solution is mixed with a water-based drilling fluid, its viscosity is almost unchanged, its fluid loss is reduced, and reduction in its compressive strength is less than in Portlandcement based material.

Keywords: portland cement; geopolymer; fly ash; cementing; water based mud; mud contamination.

Specific features of the multiphase fluid subsea pipeline operation at the liquid accumulation mode


The operation modes of an extensional subsea pipeline of multiphase fluid at the initial stage of the offshore gas condensate field development under the conditions of liquid accumulation are studied. By means of the dynamic simulation of the slug flow mode, the frequency and volume of liquid plugs removed from the pipeline are analyzed as a function of the gas flow rate. It is demonstrated that with a decrease of the gas flow rate, the steadystate hydraulic calculations predict significantly lower values of the liquid volume flow rate at the pipeline outlet compared to the results of the dynamic simulation. The dynamics of the liquid removal from the pipeline with an increase of the gas flow rate is studied. It is shown that the surge liquid volume increases sharply at a rapid growth of the gas flow rate, which leads to restrictions on the increase in the well flow rate.

Keywords: subsea pipeline; natural gas; multiphase fluid; liquid accumulation; slug flow.
