EXPLORATION AND EVALUATION OF RESOURCES
Exploration is the first step in developing a potential resource. DG offers pragmatic and cost-effective solutions for both surface and underground operations. Our services range from preliminary office surveys and remote sensing applications, to field surveys in geosciences, including geology, geophysics and geochemistry.
To maximize the value of previous efforts, we perform historical data reviews and information gap analyses, integrating past operations into customized solutions for our clients. DG understands the importance of mitigating risks during the exploration phase of geothermal development. Risk mitigation is fundamental to our philosophy, seeking high-value exploration investments and low-risk solutions.
RECONNAISSANCE STUDIES
Before conducting field work, data collection from a variety of sources, followed by careful review and interpretation, can provide valuable information about a site's geothermal potential. Reviewing historical data allows field investigations to be focused on areas with the greatest potential and priority, saving time and resources.
GEOLOGY
Surface geological exploration is critical to assessing any potential geothermal resource. Geology provides key information on the structural controls of a system, helping to identify fluid circulation patterns in the subsurface. It also offers valuable insights into the characteristics of geothermal fluids, the total capacity of the resource and its accessibility.
GEOPHYSICS
Geophysics is the industry-standard science for defining the dimensions and structure of a geothermal field, both at the surface and at subsurface depths where reservoirs and major structures related to permeability are located. Our geoscience team has experience in related fields, allowing us to conduct field campaigns as well as proper interpretation and analysis. DG is highly skilled in volcanology, geophysics, inversion theory and data interpretation, essential knowledge for project success.
GEOCHEMISTRY
Geochemical techniques involve sampling and analyzing solids, fluids, and gases from hot springs, fumaroles, surface waters, and precipitation. This allows for identifying areas of potential ascent, discharge, and recharge. Geochemistry is also used to determine fluid-mineral equilibrium temperatures in a geothermal system and the origin of reservoir fluids. Fluid characterization is crucial for initiating development procedures such as well design and location, power plant design, and even reservoir engineering.
CONCEPTUAL MODELING OF RESOURCES
Exploratory Data Integration
DG integrates diverse data obtained through field campaigns in areas such as geology, geophysics, geochemistry, hydrogeology and temperature studies, to model a potential geothermal reservoir. This integrated model depends largely on the quality and quantity of data collected during the exploration phase. At this stage, DG develops strategies to conclude exploratory procedures and initiate exploratory drilling activities. Modeling facilitates well planning, drilling site selection, future simulations, reservoir capacity estimates and successful power plant design.
By integrating data from exploration surveys and existing wells into specialized 3D modeling software, DG creates high-quality 3D models. This enables rapid and interactive visualization of exploration data, improving understanding of key parameters of the geothermal reservoir.
Based on conceptual and three-dimensional reservoir models, an estimate of the capacity of a geothermal field can be made. This estimate depends on the quality and coverage of the data, and aims to determine the location, size and geological characteristics of the resource in order to calculate its accessible base. Using appropriate tools and methods, DG can estimate the resource's potential for generating electric power.
