FIELD HYDRODYNAMICAL TESTING OF GAS CONDENSATE WATERING WELLS
http://www.ogbus.ru/eng/authors/Ponomarev/Ponomarev_1.pdf
The watering out of gas-condensate wells on Urengoi field at existing cluster well production gathering system can become the strong negative factor lowering performance of gas and condensate recovery. At the first stage creation of method of calculation of the well behavior in these conditions conducting complex hydrodynamic and gas condensate tests of several gas condensate wells with adjustable feeding water-methanol mixture into the well bottom was required. For the adequate description of a multiphase flow moving with the help of the Peng-Robinson equation the method of calculation interaction coefficients of the basic gas condensate system components at the presence of water and methanol is advanced.
On the basis of treating outcomes of such tests held on several gas-condensate wells, the updated dependences for calculation true gas-content of a multiphase upward flow in vertical tubes are obtained at a dispersion-ring-type regime of stream. Using these dependences allows to calculate values of bottom hole pressure on measured well head pressure with satisfactory for practice by accuracy.

OPTIMIZATION OF CENTRIFUGAL OIL-WELL PUMP OPERATION FOR A DEVIATION PREVENT
http://www.ogbus.ru/authors/Zeigman/Zeigman_1.pdf (in Russian)
The performance optimization of system a stratum–well-pump - is the basic difficulty of well operation. The decision of this problem is a multialternative task. It is necessary to watch mode operations of system constantly, because the system is dynamic. The reservoir properties of bottom-hole formation zone vary constantly in an operating time. The particular attention should be given on change of reservoir properties during treating bottom-hole. If the process is not observed, there can be various complications in the exploitation of well. It can be expressed especially strong in the using of electric centrifugal pumps.

TO TERMINOLOGY OF TECHNOECOGEOPHYSICS AND APPLIED GEOPHYSICS
http://www.ogbus.ru/authors/Zykov/Zykov_1.pdf (in Russian)
Within the framework of a system - methodological substantiation of a new scientific and technical direction of applied geophysics - technoecogeophysics, its conceptual - terminological basis and its parities with one-serial terms and concepts from adjacent areas - geotechnologies, technogeology, etc., and also with lexicon of the most applied (prospecting) geophysics is in detail considered.
Terms of geophysical influence (stimulation) - magnetic, electric, acoustic, etc., being by analogues of corresponding methods (investigations) in prospecting geophysics, concept of active geophysical monitoring of geological objects, etc. are proved. It is shown, that applied geophysics as the term of more general order, will consist of two equal in rights parts described by one rank terms of prospecting (explorative) geophysics and technoecogeophysics.

STUDY OF HYDRAULIC COMMUNICATION CHANNEL OF MWD (MEASURING WHILE DRILLING) SYSTEM
http://www.ogbus.ru/authors/Grekov/Grekov_2.pdf (in Russian)
This paper describes a simulator of hydraulic communication channel of MWD system as a long-distance line with distributed parameters. Impacts of different parameters of the line (line length, attenuation factor, drilling fluid density, compensator pressure, etc) are analyzed in terms of reception of the signal transmitted from well bottom by simultaneous operation of pressure sensor and drilling fluid flow sensor.
