Study of the formation conditions of the reservoir J1 to minimize the risks of high-tech drilling wells on the example of one of the deposits of JSC Slavneft-Megionneftegas

Abstract

The main factor for production wells successful placement is an accurate forecast of the geological characteristics of productive formations. Geological modelling on the basis of seismic data provides an actual areal distribution of the formation poroperm properties. Restoration of sedimentation environments, ablation and accumulation of precipitation features create a representation of the distribution of reservoir properties over the area. Dynamic parameters of the seismic wavefield are determined by the acoustic properties of rocks, thus dynamic parameters study provides presentation about the geology of objects. To analyze the variation of amplitude parameters over the laterals, a complex approach including detailed analysis of borehole and seismic data was applied. Fair presentation of prospective objects geological structure was the highlight for successful placement of horizontal wells in this field.
