The Childhood Illness of Geothermal Energy in the Paris Region
1988-1997
A decade of conceptual creativity and operational mastery. Geoproduction Consultants (GPC), the matrix of its descendants GPC Instrumentation Process (GPC IP) and GEOFLUID, originally designed as a Consulting Engineers office dedicated to the design of innovative drilling/completion/production technologies, was confronted from its creation in December 1989 with the most serious crisis in geothermal energy in the Paris region, marked by the closure and abandonment of some 21 doublets, or more than 40% of the drilled, if not exploited, park at that date These were the conditions of its creation and the challenges of its development, which made the company a major player in geothermal energy in the Paris region, which since the 2010s has become the world's leading concentration of geothermal wells for urban heating

Adolescence, learning
1998-2008v
Growth and technical and geographical diversification of the company. The absence of new deep drilling, in France as in Europe for the rest, as well as the (re)equipment of existing wells acts as a stimulant for the technical and geographical redeployment of the activity and the strengthening of the company's resources, whose workforce has been increased to twelve employees including 6 qualified engineers, 4 senior technicians and 2 qualified workers and the equipment fleet completed by a 1″1/4 Coiled Tubing Unit (UCT), 1 workshop van, a work floor for handling submerged equipment (pumps, TAI lines) and a mobile soft acidification skid which complete the laboratory of hydro/physico/chemistry of water, suspended solids and dissolved gases. In terms of diversification of the activity, let us first mention the creation of the well service, the closure, by UCT, initiated in 1997 of nearly 50 oil wells in the Villeperdue field, the construction in Romania of an all-electric drilling/workover rig with a capacity of 100 t, transported to France for the construction, by Dafora France, of four workover sites , the installation of three degassing/burning units for dissolved combustible gases (CH4, H2S), engineering studies and logging campaigns in Central Europe (Hungary, Romania, Slovakia), the Netherlands and Spain, and, another example of redeployment, intervention on geothermal operations for the production of heat/cold by surface water storage in Paris intra-muros. Promotion and signing of numerous contracts for standby/intervention/control of artesian geothermal well eruptions, as well as contracts for monitoring/maintenance of geothermal loops. Creation of GPC IP, project management company.

Adulthood, entrepreneurial maturity
2009-2021
At the meeting of geothermal and European redeployment The company, reformatted under its two companies, GPC IP invested with the functions of project manager and GEOFLUID active in engineering and services, is armed, since its structural redeployment in the field of services and operational and geographic monitoring at European level, to actively participate in the resumption of development in the Paris region, initiated in 2007 and also in Europe, from 2010. Thus, as of December 31, 2021, it will have led, as project manager, the completion of 18 deep drilling operations (Dogger objective) in the Ile-de-France region since 2011 and is participating in 2 exploration projects in the Canton of Vaud in French-speaking Switzerland. Among the most notable successes are the world firsts in geothermal well architectures recorded in Cachan (sub-horizontal doublet) and in Bonneuil (mixed anti-corrosion well with steel casing/composite materials, designed for production assisted by a submersible electric pump) awarded by EGEC (Awards 2018 and 2019)
