GEOQUIM: a Comprehensive Geochemical Toolbox for the BDGEO Software Package

Abstract

BDGEO 4.0, is our current version of a user-friendly, integrated application for storage, visualization and analysis of geothermal data. Its main goal is to standardize and simplify the assessment and management of geothermal fields at departmental level. BDGEO4.0 is set up as a distributed application over a local area network. Its main modules are a control module, a database and a visualization package, collectivelydenominated KERNEL. The KERNEL is common to all users. In addition to the KERNEL there are toolboxes, which are a family of applications for geothermal analysis and interpretation for geochemistry, well testing, production, in the BDGEO computational environment. Toolboxes are meant to be installed mostly in specialists GEOQUIM is the geochemical toolbox. It allows computation of (1) chemical equilibrium in the reservoir (speciation); (2) gas geothermometers; (3) liquid phase geothemometers; and (4) chemical concentrations at reservoir conditions. Results are presented in tabular form, and whenever appropriate, in graphical form. Theymay be either printed or saved to files. GEOQUIM has been carefully tested with field data. This application greatly simplifies geochemical analysis of geothermal reservoirs.
