FLOODING IN THE DEVELOPMENT SYSTEM WITH SQUARE HEAD-ON LOCATION OF VERTICAL INJECTION AND HORIZONTAL PRODUCTION WELLS
http://www.ogbus.com/eng/authors/Mukminov/Mukminov_2.pdf
The influence of horizontal well systems and spacing upon productivity and upon current and ultimate oil recovery can be very significant. However, this question is hardly covered in the literature.
The obtained analytical solutions show that the breakthrough time of the injected fluid weakly depends upon the length of the horizontal wellbore; the increase in horizontal well length by more than 50 % of the distance between the wells will not considerably influence well productivity and water-free oil recovery.

DYNAMIC CHARACTERISTIC APPLICATION IN OPERATING CONDITIONS CALCULATION OF MAIN NON-ISOTHERMAL OIL-PRODUCT PIPELINES
http://www.ogbus.com/eng/authors/Garris/Garris_3e.pdf
The calculation algorithm is represented in an integral form. The pipeline dynamic characteristic is defined as a set of combined characteristic of the pumps, plot of the required pump head, a grid of instant characteristics drawn with temperature or viscosity pitches, and additional temperature curves as well. The method of dynamic characteristics enables the change of pipeline hydraulic resistance, it can be used for any flow model fluids, it has been approved in operating main and industrial pipelines, having the software.

SOFTWARE FOR COMPUTING AND OPTIMIZING PETROCHEMICAL PROCESSES BASED ON GRAPHIC MODELS AND OBJECT ORIENTED ANALYSIS
http://www.ogbus.ru/eng/authors/Rudnev/Rudnev_1.pdf
The given work is dedicated to application of information technologies in petrochemical and petroleum-refining industry. A new method of the analysis of chemical flow diagrams was developed on the basis of graphic models at Ufa State Petroleum Technological university. The given method was applied together with the object-oriented principals for the analysis of composite systems in a program for chemical engineering processes simulation. This program was utilized for calculation and optimization of some units on petroleum-refining plant in Ufa. The basic methods and ideas, that were implemented during developing this program, are set up in the given publication.

METHOD OF GRAPHIC MODELS FOR ANALYSIS OF COMPLEX PROCESSES IN CHEMISTRY AND REFINING
http://www.ogbus.ru/eng/authors/Abyzgildin/Abyzgildin_1.pdf
The given publication is dedicated to the analysis of composite systems in petrochemical and petroleum-refining industry. The new method of chemical-flow diagrams analysis is developed on the basis of graphic models at Ufa State Petroleum Technological university. The given method was applied together with the object-oriented concept for the analysis of flow diagrams and simulation of processes. Such approach allows to simplify to a great extent the analysis of data domain and to use it for compilation of mathematical models.

FILTRATION VELOCITY FIELD IN THE ELLIPTICAL RESERVOIR DRAINED WITH A HORIZONTAL WELL
http://www.ogbus.ru/eng/authors/Mukminov/Mukminov_1e.pdf
The problem of fluid influx to the horizontal well drained the elliptical homogeneous-anisotropic reservoir is considered. The exact analytical solution for filtration velocity is obtained.
It is shown that the filtration velocity is maximal in the "end" points of the horizontal well. In case of circular reservoir the filtration flow is close to the radial one and the lines of equal velocities are nearly concentric circles, when the length of horizontal well is small. For middle-long and long horizontal well the filtration flow can be considered as a superposition of three constituting basic filtration flows: a linear-parallel one, which flows towards the central part, and two radial flows, which flow to the endings of the horizontal well.

GAS CONGESTION INFLUENCE ON PIPELINE SYSTEM CURVE
http://www.ogbus.ru/eng/authors/Kutukov/Kutukov_7e.pdf
Gas-air congestion is one of the typical operational mode deviations in pumping of oil and petroleum, which reduces the pipeline system capacity on an average 30:60%. The development of measures for pipeline capacity support on designed level is faced up a crucial problem of parametric diagnostic system for hilly terrain pipelines.
The qualitative and quantitative estimation methodology of possible capacity reduction for a pipeline section with gas congestion is suggested. Monitoring of pressure distribution along pipeline length allows revealing and observing their accumulation and migration in time.

HYDRODYNAMIC PRECONDITIONS OF GAS CONGESTION IN LIQUID PIPELINE
http://www.ogbus.ru/eng/authors/Kutukov/Kutukov_5e.pdf
Hydrodynamic preconditions of existence and migration of gases congestion are discussed. Hydrodynamic model of stratified flow in a hilly terrain pipeline is suggested, that allows to predict the possible location of gas congestions in the pipeline from engineering point of view. There is shown an influence of terrain features on pipeline capacity as a physical pattern in the paper.

REDOX TRANSFORMATIONS OF CYCLIC ACETALS
http://www.ogbus.com/eng/authors/Zlotsky/Zlotsky_1.pdf
It was proved that cyclic acetals oxidation proceeds with quantitative formation of glycol monoesters, which are difficult to obtain by other methods. Cyclic acetals reduction by alkyls and metal hydrides, exactly by aluminum derivatives, results in formation of monoethers. The conditions of the reaction proceeding and influence of the reagents structure on the reaction results are discussed.

INVESTIGATION AND DEVELOPMENT OF SORPTION TYPE SKIMMERS
http://www.ogbus.com/eng/authors/Khlestkin/Khlestkin_1.pdf
On the basis of formulate conception of the optimal absorbent is tested the sorption properties more 30 potential ones. There are properties of cotton manufacture residuals, named as "SINTAPEX", which possess with sufficiently high sorption ability for the numerous products. There are patented three type of basis construction for these skimmers and five their modifications. It is examined and studied some variations of skimmer sorption type and work out stochastic mathematical model in form system of 10 regression equations on the base method of planning of experiments by four main parameters which describes oil-gathering. There are permit producing in the company North-West Trunk Pipelines the experimental batch of the skimmers.

http://www.ogbus.com/eng/authors/Samoilov/Samoilov_1.pdf
The mathematical model of co-adsorption binary mixture at different relative sorbing of its components and temperatures of sorption process is considered. The activity of adsorbent by first (extractable) component is anomaly increased and have mountain-range characteristic at relative sorption more then two ones and temperatures 295-350 K. It is shown that successive sectioning adsorbers with motionless adsorbing layers and parallel sectioning adsorbers with moving layers of adsorbent allow increasing in the first case the dynamic activity of adsorbent and in the second case - degree of purification of final products.
