THE MODELING OF THE NATURAL AND PRODUCTION-RELATED BEHAVIOR OF THE OKEANSKIY HIGH-TEMPERATURE GEOTHERMAL RESERVOIR (ITURUP ISLAND)

Abstract

A numerical 3-D model is developed to describe the natural heat-transfer processes occurring in the Okeanskiy hydrothermal reservoir of the hydrothermal system of Baranskiy Volcano. The model agrees well with the data on the natural discharge of the hot springs, temperature and pressure measurements in wells, and petrophysical data. It is demonstrated that as a result of interaction between wells 51 and 53 and a group of nearby springs the operation of these wells may be of a pulsatory manner.
