Annotation:
A model of a volumetric fracture grid (MVFG) of the Lekkersky field has been compiled, consisting of parametric, geological-mathematical and graphical parts. The parametric part, on the basis of field geophysical, hydrodynamic, laboratory and seismic studies, includes substantiation of all fracturing parameters at initial reservoir pressure.
The geological-mathematical part (which may also be included in the parametric part) considers and analytically describes the dynamic relationship of fracturing parameters with any changes of the initial reservoir pressure.
The graphical part includes all information about fracturing and its change in the form of maps, geological-physical sections, graphs, etc.
MVFG made it possible to quickly revise the structure of balance oil reserves. The results of the study of the fractured component of the reservoir were used when designing the development of the Famennian deposit.
