DECISION-MAKING AT REGULATION OF THE TECHNOLOGICAL OPERATING MODE OF PUMPER OIL WELLS ON THE BASIS OF THE THEORY OF ACCIDENTS
http://www.ogbus.ru/authors/Agaev/Agaev_2.pdf (in Russian)
The article is devoted to the system analysis of technological indicators of operation pumper oil wells equipped with installations of pumper oil well. Output of oil wells, water and gas, and also delivery rate of the pump are exposed to the analysis. Such analysis is required at decision-making on regulation of work of oil extracting wells. Thus it is necessary to be guided by dynamics of change of the necessary technological indicators during a certain time interval. In most cases for this purpose in practice it is guided, as a rule, by absolute values of indicators that is erroneous as the valuable information, thus containing in initial data on tendencies of behavior of the most operated object is ignored. Thanks to this information it is possible to predict consequences of those or other actions for regulation of operating modes of wells and accordingly to appoint such changes of modes which will promote an oil recovery gain at reduction of drowning rates, economy of reservoir energy at the expense of rational redistribution of the expense of passing gas and hobby of efficiency of pump installations. For the decision of this problem, special criteria of change of operating modes of the extracting wells, based, in particular, on application of elements of the catastrophe theory are used.
In article, on the basis of the differential equations known of this theory corresponding to accident of type "fold", dynamics of change of some technological indicators, such as on outputs of oil, gas and water, and also factor of giving of the pump is modeled. These indicators easily give in to measurement and the account in trade conditions. Their processing makes more weighed decisions based on the simultaneous account of tendencies of change of the most important indicators from a point - sight of regulation of operating modes of chinks. The algorithm of calculation is described and the concrete numerical example is spent.
The given settlement scheme is computerized and used for numerous extracting chinks of the enterprises of the production association "Azneft".

ABOUT THE TECHNIQUE OF GROUPING OF OIL WELLS WITH SHOWS OF GAS BY THEIR POTENTIAL POSSIBILITIES ON THE BASIS OF PARETO PRINCIPLE
http://www.ogbus.ru/authors/Agaev/Agaev_1.pdf (in Russian)
It is known, that actions carried out on oil fields for regulation of modes of extracting wells have adaptive character, and mention not what individual objects, and all difficult interconnected and co-operating system of the elements making the developed deposit, set of operational and delivery chinks, and also a complex ground-based equipment. Such big and difficult system it is expedient to operate with use of the system approach. Thus splitting on a number of technological indicators of all fund of wells on separate groups, from for decrease in volume of the processed information, essentially simplifies and reduces the price of all managerial process. Besides at the system approach to become effective as more detailed analysis of expediency of carrying out of actions in each group, and their planning within the limits of all system as a whole.
In article as such method based on the system approach, grouping of wells by their potential possibilities proceeding from characteristics of hyperbolic distribution of oil outputs are offered. In practice, as a rule, similar properties the big and difficult systems where and it is possible to carry all process borehole workings out of deposits possess. It is known, that the behavior of these systems submits to Pareto principle, and distribution дебитов chinks on their size also corresponds to this principle. Unlike known works where, basically, are described to the mechanism of grouping of the chinks, based on quantitative signs, to article the algorithm of their "qualitative" grouping that allows to reduce and unify quantity of distinguished groups is resulted and to give them obviously known properties, inherent every possible to the versions met in practice. The number of distinguished groups is defined by quantity of processed indicators. As initial data it is used monthly average selections of oil, gas and water on each chink.
The algorithm of redistribution set chinks on eight groups, based on known property of hyperbolic distribution is stated. The given settlement scheme it is computerized and approved on a real example of the extracting wells equipped with pumper oil wells with installations and takes root for the various enterprises of a production association "Azneft". Regularly carried out calculations allows to watch dynamics of change of a condition of the chinks passing from one group in another that can promote construction of adaptive model of process of operation for all fund of wells.

SAGD PERFORMANCE IMPROVEMENT IN RESERVOIRS WITH HIGH SOLUTION GAS-OIL RATIO
http://www.ogbus.ru/eng/authors/IbatullinTR/IbatullinTR_1.pdf
Paper addresses the issue of Steam Assisted Gravity Drainage (SAGD) performance in the reservoirs with various solution gas-oil ratios (GOR). Results of extensive reservoir simulation study show that during the steam injection gas comes out of solution and accumulates at the edge of the steam chamber. In cases of high methane content in the bitumen the effect of gas layer development ahead of the steam front becomes detrimental and reduces the efficiency of conventional SAGD performance. It was suggested that by adjusting injected fluid composition it is possible to mitigate negative impact of the reduced heat transfer from water steam to bitumen.
Keywords: steam assisted gravity drainage, SAGD, bitumen recovery, thermal recovery, steam and solvent co-injection
