The Use of Seismoelectric Transformations in Reservoir Rocks for Pore Space Saturation

(Agueeva O.A. )

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.......

Saturation Characteristics and Formation Resistivity Estimates in Low-Resistance Terrigenous Reservoirs Using Well Logging Data

(Nikiforova O.G. )

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.......

Petrophysical Substantiation of Well Logging Data Interpretation vs Reservoir Rock Consolidation Estimates

(Kulapova M.V. )

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.......

Terrigenous Deposits Productivity vs. Homogeniety. The Tul-Yegan YuV1 Bed Case History

(Akhiyarov A.V. )

This article accesses productivity of terrigenous deposits vs their homogeneity on the example of Yu VI horizon (Tul- Yegan field, Nizhnevartovsk Dome, West Siberia). The authors came to the conclusion that hypsometric bindings of well sections and reservoirs’ effective thicknesses do not affect hydrocarbon yields, and the “tectonic factor" has dual effect on well productivity.......

Gravimetry Data Interpretation Using Complete Normalized Gradient Vector Angle While Upper Mantle Studies

(Yelisseeva I.S. )

Successful solution of the inverse gravity problem, using the QSP method, depends on a choice of initial parameters, which should correspond to a depth range of investigations. Along theprofde, conterminous with X =39° E, the wide (50 ... 200km) depth range was defined. Input of unified initial parameters causes an appearance offalse anomaly sources. For their revealing and elimination, some restriction on vector angle of the total normalized gradient was entered: 0 < 25° и 65° < У < 90°. It has allowed to consider as false 6 out of 18 displayed anomaly sources. It is interesting, that 10 out of 12 others satisfied to half of above pointed angle ranges.......
