Anti-corrosion well concept validated in the Paris basin


  • PUBLISHED: July 31, 2018

On July 20, GPC IP successfully completed a new anti-corrosion, fiberglass lined, production well at the Bonneuil-sur-Marne geothermal district heating site, in the Paris outskirt, scoring a new success and milestone in smart well architecture.

The well combines a large steel cased propping column and a twin fiberglass production liner assembly, the casing x liner annulus being kept free (i.e. not cemented), a design initiated in 1985 on the emblematic Melun l’Almont geothermal district heating well and completed though via a simplified architecture and production (self-flowing) mode.

The additional capital investment costs will get payed back in less than eight years thanks to yearly operation/maintenance (OM) costs savings. It is expected this smart well material answer to thermochemically hostile corrosive fluid environments, elsewhere securing well longevities and low operation/maintenance (OM) costs, raises due interest among geothermal operators and stakeholders.

The project, due to its innovative impact, was awarded financial support from ADEME, the French Environmental Agency.
