Well engineering

When the geological, technical and financial feasibility studies are concluded with positive results, the preparations for the drilling of the geothermal doublet start. These preparations are done in  three phases:

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.
