ASSESSMENT OF TECHNOLOGY IMPLEMENTATION IN THE PROCESS OF DESIGNING AND FINISHING WELLS OF THE PRECASPIAN REGION FIELD

Abstract

This article highlights the results of the assessment of the introduction of technologies in the process of designing and completing wells of an oil field in the Caspian region in Western Kazakhstan. The main results of calculations of hydraulic fracturing modeling methods for different propant permeabilities are indicated, the change in productivity in depth with different methods of hydraulic fracturing modeling is analyzed. A model has been created to analyze the sensitivity of hydraulic fracturing modeling. A new geological model of the deposit has been created, which takes into account the data of new wells drilled in 2019-2020, an updated petrophysical interpretation, an updated seismic interpretation and attribute analysis, an updated vision of the allocation of sand bodies of the reservoir. Comparative experimental dynamic calculations of hydraulic fracturing modeling methods using the EasyFrac plug-in and the HydroFrac well completion method have been carried out. Under the same initial conditions, the EasyFrac plug-in demonstrated the best possibility of liquid extraction, the pick-up of injection wells, and an earlier breakthrough of water into the producing well.
