Abstract
Exploitation of Mutnovskoe Geothermal Field, which is a key asset of geothermal power engineering in Russia, is faced with the problem connected with reduction in pressure in the producing reservoir, which results in decommissioning of production wells. Production capacity of planned wells 3 and 4 km deep for treating deeper horizons in Mutnovskoe Field is predicted. The prediction results are compared with the data of a standard production well 2 km deep in this field and prove the promising nature of the deeper horizons of this reservoir. In particular, essentially greater steam flow rate out is expected in the deeper production well as compared with the standard well. Furthermore, it is expected to produce much more geothermal energy owing to the increased allowable reduction in the reservoir pressure and thanks to additional heat elimination from larger volume of enclosing rock mass of the produced fluid.
