From the initial drilling fluids design to end of well report


Human and material resources to define complete programmes and monitor them 24/7

● Complete programmes on fluids: Drilling, Workover, Completion
● 3 “Mudlab” booths fully kitted out with API equipment.
Experienced mud engineers, both in France and abroad.
● A permanent stock of strategic products in our warehouses: LCM, weighting agent, barite, salt, carbonate.

We undertake to have 100% of relevant mud products in stock on start-up of a well, to ensure the safety of operations.

Control of solids: our own equipment delivering a reliable, efficient service

CVA has invested in equipment in order to be independent and flexible with regard to our clients.
● Centrifuges: to control density during drilling, and to dewater sludges.
– 14” / 350mm bowl – Up to 15 m3/h
– 21” / 550mm bowl – Up to 50 m3/h
● Cuttings bins, mud tanks, transfer pumps.
● Mobile warehouse with spare parts.

We select and provide access to experienced centrifuge operators, both in France and abroad.

Research and evaluation of recycling/recovery facilities that can receive solid and liquid waste

● Management of the solid and liquid waste produced by on-site drilling (cuttings and sludges).
● Waste tracking documents (BSD) to provide global traceability from the wellsite to the recovery facility.

Recovery centres are selected based on their daily processing capacity and on their analysis equipment and methods, to ensure compliance with best industry practices.
Being mindful of the environmental stakes, we are always searching for new, alternative ways of handling waste.

A central in-house laboratory supporting wellsite operations

Our in-house laboratory provides the means to qualify mud products before they are used, and mud formulations before they go to work sites.
● Mud aging under downhole conditions (T&P).
● Tribology test bench for Lubricity testing.
● R&D projects: water preservation, short supply chains, carbon footprint reduction.

A logistics centre ideally located to reach outlets from Africa to Scandinavia

Our logistics centre has:
● 750 m2 of covered storage with racks,
● 1000 m2 of outside storage.

Our freight forwarders are selected for their reliability, to guarantee a high-quality service.
