T&A's geothermal projects are focussed on risk minimalization and output optimalization. In order for a project to succeed, several steps have to be taken. T&A Survey can provide all necessary services. This way we guarantee consistency and a shorter lead time of your geothermal project.
With this short and cost-saving research it is possible to determine whether it makes sense to carry out further research into underground water resources, which can be used for geothermal energy or Heat & Cold Storage (HCS).
The quick scan consists of three successive, independent components:
- Geological quick scan: What are the geological possibilities? Should we do further investigation? To find an answer to these question we use reports, maps and raw data to assess existing depth charts and deep exploration drillings of the research location in order to determine whether a suitable geothermal reservoir is present and, if so, where it's located.
- P10-P50-P90 study: This general analysis provides an insight into the expected thermal capacity of the geothermal system.
- Financial quick scan: What are the expected costs for the construction of a geothermal system?
Based on the results, T&A elaborates a concise report. By performing a quick scan, customers can be protected from unnecessary and costly follow-up studies and procedures.
In the feasibility study, the structural distribution and the depth of the groundwater reservoir are determined, in order to map the geothermal potential of the location. T&A Survey has a fully equipped seismic working station. The software we use is The KINGDOM Suite, used worldwide by the oil and gas industry.
Subsequently we determine whether the heat capacity and the production of hot water are sufficient to meet the energy demand. To do so we use regional geological data and available borehole and seismic data. Potential sources of information are:
- Publications on regional geo(hydro)logy
- 2D and/or 3D seismic data
- Deep drillings mainly from the oil and gas industry
A. Tender phase
In the tender phase the contracts for the drilling services and equipment are selected and awarded. The purpose of the preparation and tender phase is to select a number of specialized and certified drilling (supply) companies that will perform the drillings professionally within the planning and budget.
B: Drilling management
If all feasibility studies are concluded with positive results and service providers are contracted, the actual drilling can start. In this phase, T&A's team of experienced geologists, well engineers, drilling managers and project managers manage and supervise the drilling process for you.
C: Well optimalization
After the drilling of the first well (the production well), a pump test takes place to check if the expected production can be reached. If the pump test is positive, the drilling of the injection well can start. If the pump test for both wells is succesful, the construction of the geothermal plant will be started.
