Its activities address the following areas of engineering and services:

well drilling and completion;
reservoir engineering and resource/reserve assessments;
well logging/testing, reservoir simulation and resource management;
exploitation monitoring, surveillance and maintenance of production facilities;
workover of damaged wells and completions;
coiled tubing service;
waste processing, abatement and disposal;
chemical inhibition of corrosion/scaling/microbiological damage;
feasibility studies and financial planning;
environmental impact surveys;
legal/institutional aspects of resource management.

Alongside engineering and services, GPC has developed specific R, D and D actions focused on:
Drilling/production technologies

Jetting tools for removal of casings/completions scale damage and restoration of well productive/ injective capacities.
Continuous resident downhole chemical injection and control lines.
Development of coiled tubing concepts addressing well service cementing and slim hole directional drilling applications.
Membrane volumetric pumping ("bubble pump").
Waste fluid handling/treatment lines (gas/liquid separation, solid filtering, waste water/drilling fluids cooling, gas abatement).
Soft acidizing techniques.
Well completion
Anti-corrosion well concept combining steel casings and fiberglass liners with a free annulus.
Inflatable testing/completion/production packers.

In order to secure technically sound and cost effective project completion, the in-house structure has been kept purposely light and open to foreign scientific and industrial consultants and partners. This flexibility allows to concentrate on a given objective the required conceptual and industrial expertise and know-how, the financial back-up, seldom encountered in a single firm, in informal task forces/joint ventures leading, whenever needed, to turnkey proposals.

Patents
Seven patents (France, Europe, USA) held to date, addressing downhole chemical injection/control lines, anti-corrosion well concept, sliding nozzle jetting tool, multifunction wireline logging cable, external pressurisation inflatable packer, membrane volumetric (bubble) pump, waste fluid handling/treatment unit (pending).
