Description
The Lumpfit program has been used for modeling of pressure response data from low-temperature geothermal reservoirs in Iceland and worldwide. It is based on a lumped parameter method that simulates the pressure response of a reservoir by using a small number of linearly connected homogenous volumes and a single source of production. The method has been successful in predicting pressure changes and has been applied as a resource management tool for production fields since it’s firs release in 1989. We present a new software tool, Lumpfit++, based on an updated method that can simulate pressure response in systems with multiple production and re-injection wells. For testing and refinement of the software, rich datasets from Eyjafordur N-Iceland and North-Western Poland have been used. The result of this collaboration between Icelandic and Polish partners is a time-efficient workflow and robust tools to perform reliable reservoir modelling in low-temperature fields.
The work presented is a part of project "Optimal management of low-temperature geothermal reservoirs – Polish-Icelandic cooperation on reservoir modelling" (acronym GeoModel), financed under the Fund for Bilateral Relations through the European Economic Area Financial Mechanism (EEA FM) and the Norwegian Financial Mechanism (NFM) 2014-2021.
