SIMULATION DYNAMICAL MODEL OF CYCLIC GAS-LIFT UNIT OPERATION IN FLOODED GAS WELL
http://www.ogbus.ru/authors/SokolovVA/SokolovVA_2.pdf (in Russian)
A new approach to design simulation dynamical model of cyclic gas-lift unit operation in flooded gas well on forced-oscillations regime has been developed. It gives the opportunity to simulate individual parameter-time characteristic of its operating mode as well as their correlation. The simulation dynamical model of the concerned regime is written as 5 nonlinear ordinary differential equations system. The property that define this system is that each of the equation can be solved separately, with its own input parameter.

USE OF ALIPHATIC SPIRITS AS NON-POLLUTING ADDITIVES IN AUTOMOBILE GASOLINES
http://www.ogbus.ru/authors/KarpovSA/KarpovSA_2.pdf (in Russian)
Toughening of ecological requirements to automobile engines compels the world car-building companies to search for all new and new technical decisions to keep within confirmed specifications. Driving force of this progress are the market and preservation of the environment. Due to improvement of ecological properties of automobile gasolines by introduction of aliphatic spirits the contents of toxic substances in the fulfilled gases is essentially reduced. We can produce a mix of methanol, ethanol, propanol, butanol, etc. in case of replacement the copper-zinc-chrom catalyst on potassium catalyst in process of methanol synthesis from synthesis-gas. The mix of spirits thus serves as high-octane component in gasoline and as emulsifier.

PREDICTION OF HYDRATE FORMATION TEMPERATURE FOR NATURAL GAS USING ARTIFICIAL NEURAL NETWORK
http://www.ogbus.ru/eng/authors/Heydari/Heydari_1.pdf
A great number of petroleum engineering calculations require knowledge of natural gas hydrate formation conditions. Ideally, natural gas hydrate formation conditions are determined experimentally in the laboratory, but these data are not always available. Correlations are consequently used to determine values for natural gas hydrate formation conditions. In this paper, an alternate tool, i.e. the artificial neural network (ANN) technique has been applied for estimation of temperature for gas hydrate formation.
ANN was applied to the 167 raw data in the range of 32-74 , 50-4200 psia and 0.554-1 for temperature, pressure and specific gravity, respectively. To check the ANN model, the samples were divided into two groups. One of them contained 149 samples and was used to train the network and the remaining 18 samples were used as the test sets. For the training of the different networks, the standard feed forward back propagation algorithm was used and several types of structures were tested to obtain the most suitable network for the prediction of solubility. To check the reproducibility of the results, each of the networks studied was trained three times. Finally the best ANN structure was determined as 7-5-1.
In comparison of performance analysis of ANN, the relative error (RE) was studied and maximum error found 3.035 percent and R2 value was equal to 0.9941. To ensure, the results of ANN was compared with the results of Sloan model. To sum up ANN shows the better results in comparison with it. So it can be concluded that ANN provides a good method in predicting temperature at witch hydrates formation occurs.

Scientific and technological revolution started in the latter half of the XX-th century brought the world leading countries to the progress in the national economy brunch pattern. The Soviet Union was also touched by those processes. But if in the West those changes affected nearly all economic brunches then in the USSR there were only a number of those priorities. In this respect it will be a great deal of interest to see structural contradictions formation based on the rapid growth of petroleum and petrochemical industries in the Republic of Tatarstan.
