GWELL,GWNACL,HOLA. Multi-Component, Multi-Feedzone Geothermal Wellbore Simulators

The simulators are designed to reproduce the measured flowing temperature and pressure profiles in flowing geothermal wells, and determine the relative contribution, fluid properties (e.g. enthalpy, temperature) and fluid chemical composition (e.g. CO2, NaCl) of each feedzone. Each simulator is designed to handle a specific problem: HOLA, GWNACL, and GWELL simulate `pure` water, presence of dissolved solids and presence of non condensable gases respectively. The codes can model multiple feedzones and heat loss to the formation.
