Guaranteeing compliance with regulations and preservation
of the environment over the long term

Permanently closing a well poses the major environmental challenge of ensuring that there are no pollution effects for future generations. Our approach prioritises regulatory compliance and respect for the environment, by:
● Fully preserving aquifers.
● Ensuring that no fluid rises to the surface.
● Restoring the wellsite to its original state.

Wellsite remediation
● Administrative follow-up and on-site supervision for:
● Soil and waters analysis pre-work.
● Waste management.
● Wellsite clean-up (and remediation).
● Management of contaminated sites
● Site restoration (back to its original use, soil/water remediation).

Operations supervision
● Environmental strategy counsel
● Well repurposing consultancy: Storage, Geothermal, Lithium.
