Foradex Valea Oltului

The subsidiary was founded in 2012 and is part of the Foradex Group. It operates 5 geothermal water wells, all in the Valcea County, with associated gas fuels (gas/water ratio of approx. 1-1,5 Nmc gas/mc water), with total mineralization of 13-15 g/l, temperatures of 50-96 °C and artesian capacity of 5-19 l/s.

Geothermal waters are chlorosodic, fluoridic, bromo-iodic and balneal-therapeutic, according to the analysis of the National Institute for Rehabilitation, Physical Medicine and Balneo-climatology.

In the Calimanesti-Caciulata-Cozia geographic perimeter, in accordance with the Exploitation License approved through HG No.1278/08.10.2008, published in the Official Monitor No.702/15.10.2008, the geothermal water is extracted through 3 wells drilled at 3250 m (the Calimanesti 1009 well and the Caciulata 1006 well) and at 2641 m (the Cozia 1008 well).

The 3 wells are placed on the right bank of Olt river, at approx. 1-1,2 km of one another.

The geothermal water extracted by the 3 wells is used for energy purposes with local installations and by customers for heating and hot water for domestic consumption and/or used directly in balneal therapy and in thermal recreational water pools. Gases associated with geothermal water, which have an approx. 85 % content of methane gas, are eliminated in the environment through an atmospheric degasification procedure at the head of the bores.

In 2012 the 3 boreholes produced approx. 441 000 m³ of geothermal water (approx. 25 000 Gcal) which provided for 625 apartments, 60 companies and 68 villas and houses.

Using geothermal water brought savings of approx. 2 500 TOE (Tone of oil equivalent).

Projects

In 2010 a Feasibility Study was drawn up. It proposed that a plant produced using geothermal water and fuel gases associated with it be constructed and also that the forth boreholes (the Seaca 1010 wells) be integrated in a cohesive system, fully automated. It requires the wells' maximum capacity in eruptive conditions and using 1.482.192 m³ of geothermal water per year and 2.784.000 m³ of associated gases per year for the production of 11.146 MWhel/year and 36.053 MWhth/year (31.000 Gcal/year).

Implementing the project requires 6,5 mil. Euro worth of investments and the fulfillment of a series of local conditions.
The drafted solution requires that the electric energy producing installation be placed nearby the 1009 well, where the geothermal water flow and their associated gases can be collected from all four wels, as follows:
  1. From Cozia 1008 well, Caciulata 1006 well and Calimanesti 1009 well, operating at the moment – water and associated gases;
  2. From the 1010 well, functional but unused at the moment – water and associated gases.
The geothermal resources exploitation plan in the area was drafted and adjusted for an extended utilization of geothermal resources without impacting the way beneficiaries and future clients use it.

Harnessing the entire energetic potential of geothermal water and associated gases entails the following aspects:
  1. Collecting geothermal water and associated gases, from all four wells in the geothermal perimeter on the location nearby the 1009 bore;
  2. Separating associated gases from geothermal water in a gas meter, then de-sulphurizing and drying them;
  3. Burning the methane gas contained by the associated gases, in internal-combustion piston motors, in order to obtain electric energy;
  4. Recovering the heat from burned gases that result from piston motors, in an organic Rankine ORC cycle, in order to obtain electric energy;
  5. Recovering the heat from geothermal water in an organic Rankine ORC cycle, in order to obtain electric energy.
The geothermal water flow that can be directed in the organic Rankine ORC cycle for the purpose of obtaining electric energy without affecting the geothermal water flow that must be directed towards present and potential consumers.

Currently, the Feasibility Study is in the process of being updated with new legal provisions.

In the Olanesti perimeter, during 2012, the works stated in the Prospect Permit No. 14180/2011 have continued.

The Olanesti 1007 bis well has discharged, in an artesian manner, approx. 80 000 m³ of geothermal water with an average flow of 2,5 l/s (6 l/s potential eruptive flow) and a temperature of 50oC, for the Olanesti City Hall's Recreational Treatment Base (European funds investment, based on geothermal waters provided by the well).
