It is suggested to study different size oilfields using optimum combination of independent seismic technologies: seismofacial analysis, optimized dynamic inversion, andfrequency-dependent seismic wave attenuation. The result of the study is the construction of facial model considering porosity distribution, effective thickness and hydrocarbon saturation. Data obtained in the oilfield in Western Siberia are presented.......

Usually, traditional technologies used for naturally-occurring hydrocarbons E&P are not suitable for gas/coal field studies. This article presents custom-designed two-staged integrated technique which allows to: first, produce gas from the “combined” deposit, and, secondly, produce coalfrom the same horizon. Specific exploration andfield development techniques are discussed.......

The results of laboratoiy seismoelectric researches on specimens of sedimentary rocks at their different liquid saturation coefficient ofporous space and properties of this liquid. The data testifying to dependence of kinematical seismoelectric characteristic of a transfer function from quantity of a liquid containing in rocks are obtained. The differences of phase shift between electric and acoustical signals, depending on saturation of specimens by water and not polar liquid are established. The opportunity of receiving of dependence of phase shift between acoustical and electric signals from porosity and a rock permeability is sized up.......

Estimation of resistivity and saturation character of low-resistance sedimentary rocks is always a challenge. Low resestivity of reservoir pose several problems for establishing saturation character and determining net thickness, oil/gas saturation index and fluid contact. In this article some methodical recommendations by determining rocks resistivity and saturation character of low-resestivity sedimentary rocks timed to Jurassic period are presented.......

Quite often in case of few reservoir characteristics definitions based on core data, needed for reservoir properties estimation, petrophysical correlation obtained for similar rocks with the same properties and structure are used. Thus, the degree of rock consolidation is not always considered, which can lead to substantial errors. In this paper it is shown that the influence of rock consolidation on petrophysical correlation, could be used for reserves estimation.......
