Abstract: The cases of the formation of man-made hydrogeological anomalies in the development of oil and gas fields are considered. These include hydrochemical, hydrodynamic and hydro-geo-thermal anomalies. In the oil and gas provinces fusion of the hydrogeological anomalies into man-made hydrogeological systems is observed. Disposal of industrial waste also leads to the formation of man-made hydrogeological anomalies. No less dangerous are radionuclides that occur in groundwater as a result of nuclear explosions at oil and gas fields. All this requires constant geo-environmental monitoring of underground hydrosphere.

Using petrophysical model of effective industry in geomodeling
Petroleum geology, geophysics

Authors: The concept of effective pore space actualized the need for information technology, to solve the problems of geomodeling of oil and gas fields with the aim of calculating dynamic parameters of reservoirs and «non-reservoirs» (effective and dynamic porosity as well as effective permeability for water and oil). This technology is implemented through a system of adaptive interpretation of well logging data, comprising petrophysical, methodological and interpretational-algorithmic software based on new methodological principles: adaptability and petrophysical invariance of granular reservoirs. The substantiation of the petrophysical invariant as interpretive parameter of logging methods allowed to move from empirical algorithms to the algorithms of interpretation, relying on the analytical petrophysical models of reservoirs, with the model of effective porosity being the basic one.

Abstract: The paper suggests the use of alternative ac converter-fed motor (ACCFM) as the drive for sucker rod pumping units (SRPU) instead of asynchronous motors with a squirrel-cage rotor. Key indicators of the efficiency of the SRPU are presented and the possibilities of improving them applying ACCFM are proposed. It is suggested to use an electro-mechanical model of the ACCFM to study of its dynamical regimes for the specific nature of the SRPU load. The results of modeling are found to correspond to the physical description of the considered transients.

Abstract: The paper offers new principles of approach to the development of oil fields, considered as a complex dynamic system, the analysis, diagnosis, prognosis and management of which are based on a multidisciplinary approach of the theory of large systems. The the principle of «composition and decomposition is crucial here». In accordance with the principle of the integrity of the process of development of the field can be described using the models of macro and micro levels. The necessity of taking into account the interaction of the effects of low temperature and pressure, as well as of various gas-hydrodynamic phenomena occurring in the reservoir system, which result in the development of synergistic effects is shown. Combining the approaches of synergetics and the theory of fractals allows to solve the pressing problems of establishing the relationship between micro- and macro-characteristics of the development processes. It is proposed to consider an oil reservoir as an open dissipative system, capable of self-organization. A self-organizing reservoir in many cases is able to adjust to a rational mode at relatively low material and energy costs.

Abstract: The values of current density for the economic current density for pricing of 1980 and 2010 are calculated. The calculated values of economic current density are compared with standard values. The spread of economic current densities depending on the price of electricity in December 2010 (by region) and the price of cable products (prices from multiple vendors) is shown. On the example of a typical power supply circuit of gas turbine compressor station a method for selecting the cable line sections using the methods of multi-criterion optimization is proposed. In analyzing this issue, all studies were conducted on the example of the four types of cables: with aluminum and copper conductors, paper and plastic insulation and voltage of 6 kV and 10 kV.
