Current Situation and the Further Prospects of the Bazhenov Suite Development in the Salym Field

(Stepanov V.P. Achapkin M.Y. Tabakov V.P. Pasynkov A.G. Bykov V.V. Baturin Yu.Ye. Sonich V.P. Vassilyev V.V. Afanassyev D.A. Andreeva T.V. Shatrovsky A.G. Zakrinyuchny L.V. )

This article addresses the Bazhenov suite - a unique reservoir for oil and gas E&P. Due to highly heterogenious, or “mosaic”, reservoir structure, low filtration and capacity characteristics, etc., development of the Bazhenov suite, Salym field (West Siberia) is still in the pilot stage. For the time being, 63 out of 72 pilot wells drilled in the area are out of production. Thus, it is high time to set up new approaches towards further development of the Bazhenov suite.......

Laboratory Studies of the Russkoye Field Highly-Viscous Oil Displacement at Reservoir and Elevated Temperatures

(Achapkin M.Y. Gubanov V.B. )

Senomanian oil-and-gas reservoir with bottom water (within PK formations) in the Russkoye field has vast and hard-to-recover oil reserves. The difficulty in effectively producing the reservoir consists in highly viscous oil-in-place is. The geology of Russkoye field is such that the traditional production stimulation by steam injection is appreciably expensive. The article presents lab studies on oil displacement by water flood and by other solutions at different temperatures. Based on the results, guidelines were defined along which the creation of an effective and rational reservoir stimulation technology should proceed. The technology is expected to combine both heat and chemical stimulation by injecting heated water-based solutions.......

Studies of Multiphase Filtration Parameters while the Development of Highly-Viscous Oils Using Thermal Injection

(Stepanov V.P. Achapkin M.Y. Vazheyevsky A.Ye. Rodionova Ye.A. )

Displacement efficiency, relative phase permeabilities and their variations vs. temperature and driving agent dependency have been experimentally and quantitatively determined to facilitate numerically thermal and hydrodynamics-based indicators to guide the development of a high-viscosity hydrocarbon reservoir fringe. Utilization of these characteristics of multiphase flow while modeling permitted the effectiveness of a non-isothermal flood ranging while cold water injection (1 = 5°C) to steam injection (t = 320°C) to be investigated.......

Integrated Use of Filtration and Core Data to Enhance Petrophysical and Hydrodynamic Models Reliability

(Semenov V.V. Achapkin M.Y. Vokin R.D. Yepishin K.N. )

Pacing factors which influence the shape of relative permeability vs. phases (RP) curves, obtained in the lab conditions are considered. Dynamics of stream processes and final value of blow-down recovery depending on a degree of variability of properties of a header is analyzed. The method of alignment of an input profile with usage of chemicals is offered. The intercouplings are also analyzed: RP - character of fluids inflow into the well, RP - specific resistance/saturation, RP - thickness of water to oil transition zone.......

Types of Salt Tectogenesis in the South-East of the Pre-Caspian Depression by CMP Data

(Shlezinger A.E. Yermakov B.V. Kirevichev V.K. Larina T.Ye. )

Saliferous tectogenesis in the southeast of the Precaspian Depression is confined to primary salt outflows into Late Permian - Triassic sedimentation basins followed by the formation of negative coeval tectonic structures. Saline domes growth was impulsive and occurred within the limits of Late Triassic, Jrassic and Cretaceous passive solt ridges, and has ended with a Post-Cretaceous impulse.......
