Interpretation of field methods for determining the permeability of an oil reservoir (Urnenskoe field, Tyumen region)

Abstract

The article analyzes the results of hydrodynamic well testing performed on Urnenskoe field during its investigation. The important role of technical factors such as the near-wellbore zone mudding is shown with the use of numerical methods for modeling the processes of underground hydrodynamics shows. This leads to incorrect values of permeability in the processing of the results of well testing using standard Horner techniques. In practice, this often occurs when the backlog of fracturing in production wells. Refs 6. Figs 3. Table 1.
