Summary

Core business : CFG Services offers an integrated scope of services for your geothermal project, from prefeasibility studies, to deep drilling

supervision and geothermal loop maintenance and monitoring.

At your side at each step of your geothermal project development and operation!

CFG Services figures Average turnover : 5 M€ 20 contracts for geothermal loop monitoring Management and supervision of more than 120 geothermal well drilling in France

and abroad 70% market share for the drilling supervision of new doublets in France since

2007 30 employees

A pluridisciplinary team: Geology, hydrogeology, reservoir engineers

Drilling engineers and supervisers

Thermodynamic, thermic, fluids

Electrotechnical, mechanical

Chemistry, biochemistry, corrosion

Economics, project financing

CFG Services role in a deep geothermal project Identify and validate the most pertinent technical scenario for the geothermal project

(including geological, hydrogeological and geochemical studies).

Make the project compliant with the local legislation/regulation (Mining Code / Regional authorities).

Determine the financial scheme of the project (in collaboration with a « surface »

engineering company) and plan it.

Assist the project developer in seaking financing Look for the best performing companies for the project realisation (Tendering –

Companies selection – Realisation control).

Assist the project developer during the contracting phase (technical and administrative assistance).

Supervise Well drillling (including well pad preparation, geological and mud logging, drilling, production + injection tests, diagraphy controls) and ensure a timely delivery of the operations, liaising with the project owner and the numerous subcontractors.

Proceed to final reception of the completed geothermal loop and commissionning.

Assist the geothermal operating company during the lifetime of the plant (>30 years) for

monitoring, work-over, submersible pumping groups movements, logging operations, etc…

During drilling works, CFG Services offers a one-stop shop for the geothermal plant developer, assisting you in tendering and selection of companies. We supervise the geothermal drilling works on your behalf, insuring

a timely delivery of the underground works.

CFG Services will adapt to your contract mode with the drilling company whether it is a lump sum or daily-based

CFG Services can bring on site its own team to:

Installation and maintenance

Design, install and maintain the well heads Define the specification and install the submerged pumping equipment (total

warranty contract available) Design, install and maintain of down-hole inhibitor treatment system Proceed to soft acidification of well casings Check borehole casing and tubing integrity Supervise Work-over for all types (scale mechanical removal, casing

relining…)

Inhibitor tank and pumping station Well head installation Pump installation

CFG Services is marketing and installing its own downhole treatment tubing system to prevent corrosion and scaling through the injection of inhibitors and biocides. Our system is tailored to

the specific requirement of each geothermal well.

Insuring the protection of

the entire geothermal

loop (well and surface

equipment)

CFG Services can provide assistance on the long-term well integrity, through monitoring of the geothermal loop:

Corrosion expertise Expertise on the origin of deposits formation

Operational monitoring

Geothermal loop diagnostic on a yearly or trimester basis Geochemical monitoring of the geothermal fluid Monitoring of the submersible pump systems Monitoring of the scaling and corrosion evolution in the geothermal loop Monitoring of the well integrity Adaptation of the inhibitor treatment Supervision for all types of well logging (multifinger Caliper, Electromagnetic

scanner…)

On site monitoring

CFG Services has developed a cost effective method to monitor the well integrity.

Well integrity

• Filling up the exact casing volume with a fluorescent marker and soft water

• Stand by for a precise duration • Let the artesian well push out the soft water • Monitor the timing, the volume, the temperature and the ion concentration

Manage to identify: depth of the leakage flow rate of the leakage For a limited cost and a minimal disturbance of the well production
