Kazimir V. KOVALENKO graduated from Gubkin Russian State University of Oil and Gas 1997, assistant-prof. at Dept. of geophysical information systems at Gubkin Russian University of Oil and Gas, candidate of technical sciences. Specializes in methodological support and algorithmiaztion of petrophysical interpretation of logging data. 26 publications. E-mail: biblioteka@nedrainform.ru

Abstract: The petrophysical invariance determination as an interpretation parameter of well logging data has allowed to move from empirical algorithms («cross-plotting») to the algorithms of interpretation which are based on analytical petrophysical models of reservoirs reflecting set of conditions of their genesis. The principle of petrophysical invariance has allowed to present in generalized analytical form the dependence between interpretation parameters and filtration-capacity characteristics of complex reservoirs. In deficiency of petrophysical information or even in absence of reference layers adaptive tuning of algorithms reduces the number of errors sources.

Gas state effect inside pore space on characteristiscs of Frenkel-Biot P-waves
Drilling and development of hydrocarbon fields

Authors: Dmitry N. MIKHAILOV (b. 1974). Education: Moscow State University, Physics Department (1997) and Computational Mathematics and Cybernetics Department (1997). Current Job: PhD, Senior Research Scientist, Institute of Earth Physics, Russian Academy of Sciences. Scientific interests: multiphase multicomponent fluid flow through porous medium, wave propagation in porous medium. 27 publications. E-mail: dmikh@yandex.ru

Abstract: Three typical cases when gas inside pore space forms bubbles are considered: gas microbubbles occluded in continuous saturating liquid; microbubbles adsorbed on pore surface; marobubbles occupying one or several pores. Theoretical analysis of the effect of these gas states on the characteristics of Frenkel-Biot P-waves is carried out. Analytical expressions for phase velocities of Frenkel-Biot P-waves are derived for low-and high-frequency ranges. It is shown that attenuation coefficient of 1st wave (i.e. P-wave which is determined mainly by compressibility of saturating liquid and material of porous matrix) essentially depends on gas state inside the pore space. Since the presence of gas microbubbles occluded in continuous saturating liquid is important for some practical applications (for example, some techniques to enhance oil recovery), the attenuation coefficient of 1st wave can be used as a diagnostic parameter.

Abstract: Results of plasmachemical methane processing studies proved their efficiency for hydrogen production are presented. It is shown that crude mixture conversion up to 90% is provided with energy expences as low as 2,0-2,5 kWh/(m3 of input methane). It is possible to alter H2:CO ratio in range 3:1-1:1 by varying input components (oxygen, water vapor, carbon dioxide, methane homologs). With H2:CO ratio 2:1 energy expences equal 1,1-1,3 kWh/m3, with ratio 1:1 equal 0,7-0,8 kWh/m3.
