Conference Paper: Fluid Inclusion Stratigraphy Interpretation of New Wells in the Coso Geothermal Field

Abstract
This paper is the fifth in a series about the development of the FIS method. Fluid Inclusion Stratigraphy (FIS) is a new technique being developed to map borehole fluids in geothermal fields by analysis of fluid inclusion gaseous species in drill cuttings. The working hypothesis is that selected gaseous species and species ratios can differentiate groundwater and reservoir fluid-bearing fractures, and can indicate reservoir seals. Analyses are performed by a commercial laboratory, Fluid Inclusion Technologies (FIT) and also by the research lab at NMT. This research is funded by the California Energy Commission. The first four papers interpreted analyses of 4 bore holes. Here we report on the analysis of five additional wells. This paper focuses on the interpretation of the additional wells and comparison to the previous wells. Preliminary correlation between wells is also presented. Analyses from multiple boreholes show fluid stratigraphy that correlates from well to well. The wells include large producers, small to moderate producers, problem producers, injectors, and non-producers.
