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

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, host rock temperature, and the production time. The range of the fracture length considered in the nomogram varies from 100 m to 1000 m whereas host rock temperature can be selected from a range of 100 o C to 260 o C. The production temperature predicted by the nomogram agrees well with the analytical solution. The most attractive feature of the proposed technique is its extreme simplicity and speed of operation.

Nomography: A renewed pedagogical tool to sciences and engineering high-education studies

“…Thus, the number of nomography-based articles published in recent years has been quite scarce ( Glasser and Doerfler, 2019 ; Toumès, 2012 ; Doerfler, 2008 , 2009a ). Among the most recent and relevant works in applied nomography are those focused on medicine ( Chen et al., 2021 ; Potente et al., 2019 ; Iasonos et al., 2016 ; Marasco et al., 2011 ; Kattan and Marasco, 2010 ; Bevilacqua et al., 2007 ; Kattan et al., 1999 ), geothermal applications ( Ekneligoda, 2015 ), forensics ( Drábek, 2014 ; Henssge and Madea, 2004 ; Henssge, 1992 ), seismic hazards studies ( Douglas, 2018 , 2021 ; Douglas and Azarbakht, 2021 ; Douglas and Danciu, 2020 ; Gkimprixis et al., 2019 ; Mahdyiar, 1987), engineering and mathematical education ( Uzoigwe et al., 2017 ; Glasser and Doerfler, 2019 ). Moreover, the study of the practical application of nomography has been dismissed from most sciences and engineering universities syllabus.…”
