A Design Nomogram for a Horizontally-Fractured Geothermal Reservoir to determine the Production Temperature

T.C. Ekneligoda Abstract: The paper presents a graphical technique for the rapid analysis of the complex, nonlinear equation that describes the variation of the production temperature of a horizontally-fractured geothermal well. The nomogram presented for the evaluation of the production temperature incorporates the mass flow rate, fracture width, fracture length, number of conductive fractures...

New Project for Hqt Wet Rock Geothermal Reservoir Design Concept

This paper presents the outlines of a new Hot Wet Rock (HWR) geothermal project. The goal of the project is to develop a design methodology for combined artificial and natural crack geothermal reservoir systems with the objective of enhancing the thermal output of existing geothermal power plants. The proposed concept of HWR and the research tasks of the project are described.

Reservoir Assessment of the Olfus-bakki Low-temperature Geothermal Area, Sw Iceland

The Olfus-Bakki geothermal area (OBGA) in SW Iceland is located in the S and SE margins of the high-enthalpy systems of Hveragerdi and Hengill, respectively. This geothermal area contains a productive region, denominated the Bakki field, which produces fluid at temperatures in the range of 100-130 °C. Since 1979, the geothermal resource has supplied thermal energy to the town of Thorlakshofn, m...

Sgp - Tr - 145 Use of Slim Holes for Geothermal Exploration and Reservoir Assessment : a Preliminary Report on Japanese Experience

The publicly available Japanese data on the use of slim holes in geothermal exploration and reservoir assessment are reviewed in this report. Slim holes have been used for (1) obtaining core for geological studies, (2) delineating the stratigraphic structure, (3) characterizing reservoir fluid state (pressure, temperature, etc . ) , and (4) defining the permeability structure for reservoir asse...
