Normalization methanol consumption in underground gas storage facilities
Geosciences

Authors: Andrey S. SERGEYEV was born in 1989; he graduated from Gubkin Russian State University of Oil and Gas in 2012. He is currently doing a postgraduate student of the Department of Development and Exploitation of Gas and Gas Condensate Fields at Gubkin Russian State University of Oil and Gas.E-mail: sergeand@bk.ru

Abstract: The given work includes the normalization principle of methanol specific flow worked out with the participation of the author and currently applied in „Gazprom PHG” LLC underground gas storage facilities. The methanol discharge rate on the operating procedure, which was earlier a unified value for the whole production period, is the equation of dependence of methanol specific flow on formation pressure variation. The work draws comparison of two hydrate control approaches applied in underground gas storage facilities. The approaches with primary hydrate prevention and primary deposition destruction have been distinguished. The work tells about developing application software for methanol feed control the outcoming data of which will be the basis for the following methanol flow normalization. The requirements for the given development have been provided

Abstract: The article deals with the problem of parametric diagnostics of trunk pipelines, i.e. impact of branches coordinates and insert parameters on the parameters of the pumping mode. The reasons of the changes of the technological parameters of complicated trunk pipelines are studied. The calculations were performed using the author’s software „Trans Gubka”. The effect of the branches coordinates and inserts parameters on the pumping mode was evaluated and the ambiguity of the dependences is shown. This is displayed when evaluating the results of the work of the leak detecting systems

Abstract: Industrial oils are the foundation for commercial oils used in industrial machinery, which operating in areas with ambient temperatures -40 °C and lower. Depressants, in particular polymethacrylates, are applied to improve the low temperature properties in lubricating oil. Purpose of this work is to study the possibility of modifying the structure of additives by means of preliminary heat and ultra-sound treatment of polymethacrylates for improvement of their depressant and viscosity properties. Ultrasound treatment was performed at frequency 22 kHz within 10 min, heat-treatment — at a temperature of 80±2 °C within 60 min. Evaluation of the results pretreatment of oil samples with additives after their oxidation was conducted by the method of SRT „Gazprom” 2-2.4-134-2007. Physico-chemical properties of the oils were determined by standard methods. It is shown that additives reduce the pour point of the base oil at 5-7 °C and a kinematic viscosity was increased on average by 10-15 % under optimum processing conditions. Reduction of the additives consumption with pretreatment for increasing the viscosity of the oil and reducing the pour point to the established norms has high practical significance

Abstract: Investigation of the process of gel formation in dilute and semidilute solutions of xanthan was performed by rheological methods as well as by NMR spectro-scopy, scanning electron microscopy and small-angle X-ray scattering (SAXS). We estimated the average molecular weight of the polymer by the Mark-Hou-wink-Kuhn relationship and the radius of gyration of solvated macromolecules. From the concentration dependence of the dynamic viscosity of the aqueous polymer solutions the overlap concentration of polymer chains of xanthan was determined. The pH values allowing the formation of gels with optimum viscosity by cross-linking of macromolecules by chromium ions were found. The SAXS and electron microscopy results allowed estimating the structural parameters of the system before and after the binding of polyvalent ions to polymer chains

Abstract: The effect of the quantitaty and salinity of produced water on the intensity of the precipitation of the water-oil emulsions is studied. It was found that for Udmurtia oils characterized by a high content of high molecular weight resin-asphaltene compounds with the share of the aqueous phase growing up to 80 % the stability of oil-water emulsions increases and, thus the number of AFS increases as well. Reduced salinity of produced water increases the aggregate stability of the emulsion, which enhances the formation of deposits

Temperature features of rheological behavior of structured crude oils

Authors: Nikolay Yu ELISEEV. graduated from Gubkin Russian State University of Oil and Gas in 1988, he is Candidate of Technical Sciences, assistant professor of the Department of Physics of Gubkin Russian State University of Oil and Gas.

E-mail: eliseev@gubkin.ru

Abstract: On the basis of pilot rheological studies structural transitions in oil between free disperse state and bound disperse state are found. This effect consists in the system oscillation, with «viscosity bifurcation» at small shift speeds characteristic of this condition of oil. The structural state of samples of heated-up oil was described as «liquidlike» while that at formation temperatures as «solidlike». The structural phase transition of the oil in question from solidlike state to liquidlike state occurs at Тс = 26,5-27,5 °С. The studied oil is a high-concentrated disperse system with increased viscosity explained by capture of considerable volumes of oil in the microgel dispersed particles created by colloids of asphaltenes and waxes

Method of assessing Oil Recovery factor (ORF) value for new fields developed with use of waterflooding
Geosciences

Authors: Larisa N. NAZAROVA graduated from Gubkin Moscow Institute of Petrochemical and Gas Industry in 1979. She is Candidate of Technical Sciences, Associate Professor of the Department of Development and Exploitation of Oil Fields of Gubkin Russian State University of Oil and Gas. She is specialist in the field of development and design of oil fields. She is author of more than 50 scientific publications. E-mail: Nazarova-ln@irmu.ru

Abstract: A new methodology for rapid assessment of the ORF obtained on the basis of statistical processing of the actual results of the development of terrigenous and carbonate pore type reservoirs is proposed. The results of the use of these dependencies for reservoirs with different hydro-conductivity values are presented. The technique can be used when assessing the ORF of new fields without high quality information for full-scale calculations using 3D hydrodynamic models as well as evaluating the effectiveness of investment projects
