In connection with an Enex Solution; offered services include :

Geothermal resources have been utilised for over 70 years in Iceland. Therefore, Enex, which is owned by the Icelandic companies who have led the development from the start, has world leading geothermal expertise and experience that it puts to use when designing geothermal solutions.

Enex offers reservoir consulting and services, often in connection with an Enex power plant:

Enex' sister company  has successfully drilled over a thousand high and low temperature geothermal wells of depths from 300 m to 2600 m, in widely varying conditions of volcanic and sedimentary formations. The temperatures range from 50°C to 400°C.

The drilling operations mostly concern the acquisition of :

  • Hot water
  • Geothermal steam
  • Cold fresh water
  • Sea water

What is Geothermal?

Prior to implementing the engineering and design appropriate to a given energy development, as is normal with most large-scale developments, there are three basic study phases that Enex highly recommends to be completed, mainly:

  • A reconnaissance or pre-feasibility study phase
  • An environmental impact assessment (EIA) phase
  • Feasibility study phase.

There are numerous benefits to be accrued by utilising energy resources in an integrated manner such as by integrating different energy resources into a single energy facility. The same is true of utilising the same resource or different resources together for a number of different applications in cascade or in parallel.


A great example is the Blue Lagoon, located at the Svartsengi CHP geothermal plant.

Some of the more important applications of integrated use are:
  • Vastly improved financial viability
  • Considerable energy conversion efficiency gains
  • Significant environmental benefits
  • Greatly enhanced application and operating flexibility
  • Improved marketing versatility

The thermal energy stored within the earth's crust is collectively called geothermal energy. In some parts of the world hot rock formations within the crust contain water, which is the ideal medium for carrying this energy up to the earth's surface in a useful form.

Geothermal activity, such as hot springs and fumaroles, have been known and made use of for many centuries in places as far apart as China, Latin America and Central Europe. But where does all this hot fluid come from?
