Geophysical Methods for Determining the Reservoir Properties of Structurally Complex Lower-Middle Jurassic Reservoirs within Hydrocarbon Fields in the Latitudinal Ob Region

摘要

The use of geophysical well logging for interpreting structurally complex oil-saturated intervals of the Lower and Middle Jurassic horizons that are characterized by a high average number of permeable intervals and by the presence of semiconductor minerals (pyrite, siderite, glauconite, and others) is considered. The complex of geological and geophysical information that has been aggregated and research methodology that has been developed for areas with hard-to-recover reserves is developed based on the example of deposits that have been in operation for many years.
