Title: Reservoir Temperature Estimator

The Reservoir Temperature Estimator (RTEst) is a program that can be used to estimate deep geothermal reservoir temperature and chemical parameters such as CO2 fugacity based on the water chemistry of shallower, cooler reservoir fluids. This code uses the plugin features provided in The Geochemist's Workbench (Bethke and Yeakel, 2011) and interfaces with the model-independent parameter estimation code Pest (Doherty, 2005) to provide for optimization of the estimated parameters based on the minimization of the weighted sum of squares of a set of saturation indexes from a user-provided mineral assemblage.

Other Software Info:
RTEst uses a multicomponent equilibrium geothermometry approach. It provides a Windows interface for users to specify the working directory, the react file that contains the chemistry of the water being used to make the geothermometry calculations, and an RTEst input file that provides information about the parameters being optimized and the mineral assemblage to be used in calculating the objective function to be minimized. Another form provides text, check, and dropdown boxes to assemble the input file. The program provides filters to aid the user in selecting an appropriate mineral assemblage based on the rock type, water chemistry (acid versus neutral), and general temperature range for the formation of the alteration minerals (low, moderate, high). The user can also test to see if the selected mineral assemblage violates the phase rule. The method involves minimizing the weighted sum of squares of the saturation indices in the selected mineral assemblage. The user can choose three different weight schemes (unit values, normalization, and inverse variance). A Setup program to aid the user in installation is included with RTEst.
