Resource Development Planning, Feasibility & Due Diligence


Geologica Geothermal Group focuses our resource development studies and planning on collecting the necessary information for performing quantitative analysis of resource characteristics (such as size, heat, well productivity, and/or chemistry) based on a thorough conceptual understanding of the reservoir. Our data collection efforts for this phase of geothermal development include well drilling and testing, heat flow and seismic studies, detailed geoscientific studies, tectonic setting, reservoir geochemistry, static and dynamic well measurements and reservoir evaluations. We have performed well flow testing and geochemical sampling on individual exploration wells as well as entire wellfields during production. Our testing experience includes tracer testing and enthalpy testing of saturated and superheated steam, two-phase systems and single-phase brine.

Our focus includes conceptual and quantitative modeling for characterizing resource potential for initial project development, development planning, feasibility studies, due diligence, project life extension and expansion. Our personnel are accomplished at integrating and interpreting acquired data to develop or refine the conceptual or numerical model of a geothermal system.  We apply our expertise in geothermal systems to develop numerical simulations firmly tied to a viable conceptual model.

Our geochemical work has contributed to scaling and corrosion mitigation plans, evaluation of recharge, and injection strategies. Our use of geophysical and drilling data has contributed to determining the proven, probable, and potential limits of geothermal reservoirs.  Additional work in plant engineering has contributed to management of geothermal fluids and non-condensable gases, formulation of plant processes, economic evaluations, and environmental impact mitigation.

Geologica Geothermal Group has performed numerous due diligence studies of geothermal facilities from evaluation of resource capacity and reserves, expansion and development costs, drilling risk assessment, power plant operations and maintenance to environmental compliance and risk related to potential soil and regional hydrogeology. Data is interpreted and integrated into a conceptual model which describes the geometry, heat fluid flow, and geochemical dynamics of the reservoir.

Numerical simulations, grounded in the conceptual model and calibrated to natural state conditions, and production histories are used to evaluate reservoir decline and to guide resource optimization.

We apply our thorough understanding of the geothermal development process and facilities, and of the uniqueness of geothermal systems throughout the world, to address and quantify the risks related to the acquisition, refinancing or continued development of geothermal resources and power plants.
