Identification of increased fracturing zones of the Neftekumsk natural reservoir on the Vostochno-Bezvodnenskoye field using the software product “tNavigator”

| الملخص: | The oil-and-gas fields in the Eastern Fore-Caucasus, the oldest oil-and-gas region, are at the stage of declining production or have been completed, so there is an urgent need to increase the hydrocarbon potential. The object of the study is the Neftekumsk fractured carbonate formation (Lower Triassic), which is promising in this regard, on the Vostochno-Bezvodnenskoye field, which is located in the East of the Stavropol Territory. The deposits of the field have a high degree of spatial heterogeneity, reflected in the mosaic of zones of increased oil recovery. The establishment of distribution patterns of such zones will make it possible to create the most optimal digital geological model of deposits. The aim of the study is to take into account the results of the identified patterns of the increased fracturing zones distribution of the productive reservoir when substantiating promising exploration and development facilities for the Vostochno-Bezvodnenskoye field. Methods. The study used the method of correlation analysis of oil production parameters and spatial characteristics of the location of wells obtained as a result of structural decoding of remote sensing materials, as well as the method of modeling the zones of improved reservoirs in the domestic tNavigator software package, taking into account the new received data. Results. Based on the data obtained during the processing of geological and field material and the results of remote sensing materials, linear zones of increased productivity were identified in the Neftekumsk carbonate formation of the Vostochno-Bezvodnenskoye field. Tectonic and lithological-facies criteria have been studied and applied to account for the results of the identified linear zones of increased reservoir productivity in a digital geological model. The authors of this study have constructed a map of the lateral distribution of the fracture network in tNavigator software, taking into account the developed generalized coefficient of fracture intensity. As a result of comparing maps of parameters affecting the amount of accumulated oil production, the authors identified the zones that are most optimal for the location of infill drilling and well intervention. |
