Based on the results of the previous works performed at the studied oil field, a significant potential for increasing initial oil reserves was established. Three wells were drilled in the edge zone of the field at the end of 2019, which confirmed the potential in the undrilled area of the northern flank of the filed. Until these wells were drilled, the edge zone was considered unpromising.
The authors have been tasked to assess perspectives of development of edge zones and build a detailed geological model for that area. The detailed model is intended to forecast the evolution of elements of the fluvial system for based on drilling data and results of seismic researches in undrilled parts of field.
In order to forecast the distribution zones of channel complexes, high-resolution 3D seismic data of 2019 were used. Based on the dynamic analysis, interpretation of the distribution zones of channel complexes and their classification within the studied reservoir layer were performed. The main focus was on identifying and mapping of small channels in the boundary zone of the reservoir with the aim of further detailed geological modeling and assessment of the development potential, taking into account new data.
