Authors: S.I. Chizhov (RITEK OAO), D.S. Sergeev (Branch of RITEK OAO – Volgogradneftegaz TPP), N.S. Sibileva (LUKOIL-Nizhnevolzhskneft OOO), A.N. Stepanov (LUKOIL-VolgogradNIPImorneft OOO), M.A. Sybilev (LUKOIL OAO)
The revealing of regularity of change of reservoir properties (porosity) and formation hydrocarbon systems through the deposits height are of significant theoretical and practical interest for the massive (reef) deposits. Processing of the results of complex field-geophysical studies (porosity determination) through the wells of evlano-livenskiy horizon of Pamyatno-Sasovskoye field, semiluksko-rudkinskiy horizon of Kliuchevskoye field is carried out. Depth probes of oil of Pamyatno-Sasovskoye field are selected and analyzed. In general, significant changes in properties of reservoirs and oil through the deposits height are not revealed.
