GPC INSTRUMENTATION PROCESS (GPC IP) is a consulting engineers bureau and a service company, created in 1989 from a nucleus of professionals experienced in exploration and production of underground fluids (ground water, hydrocarbons, geothermal -hot water and steamsources), with a view to promote new drilling/completion/production technologies.
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.
