Abstract
The article considers the experience of using infill well patten in the territory of Western Siberia. The justification of geological and geotechnical factors affecting the efficiency of infill drilling with the subsequent use of a sector-crushed hydrodynamic model of the field site is given. With the help of the identified criteria, promising areas of infill drilling of wells are mapped, and it is established that increasing the detail of the grid of the hydrodynamic model makes it possible to clarify the localization of remaining oil in place. Based on the obtained results from the hydrodynamic model, variants of adjusted planned well count are compared according to accumulated and annual indicators. Thus, the infill well drilling program is optimized. The implementation of an integrated approach to the selection of sites for compaction drilling and the use of a detailed hydrodynamic model of this site allows to increase the production efficiency of recoverable remaining oil in place, as well as to level the risks of oil production.
