Coiled tubing

The most popular use for coiled tubing is circulation or deliquification. When a hydrostatic head inhibits the flow of formation fluids due to its weight the well is referred to as having been killed. The safest solution is to attempt to circulate out fluid using nitrogen. Circulating can also be used to clean out light debris, which may have accumulated in the well hole.

Enhanced oil recovery (EOR)

Air Liquide offers gases, technologies and services for Enhanced Oil Recovery operations that improve hydrocarbon production processes and increase output.

Gravity drainage

Low density nitrogen can enhance the gravity drainage of a steeply dipping reservoir. In deep reservoirs, gravity stable miscible displacement could be achieved with nitrogen.

Hydraulic fracturing

Fracking fluids are sent down a wellbore at high pressure in order to create fissures in the underground formation in order to release trapped oil or gas. Nitrogen or carbon dioxide is used in foam-based fracking fluids.

Pipeline purging

Nitrogen is used as a high-pressure purging gas or to pump devices through a pipeline to clean out the walls. Nitrogen can also be used to pressurize pipes for transfering products.

Petroleum analysis

Air Liquide supplies industrial gases and pure specialty gases mixtures to enhance reliability and provide precise calibration for accurate exploration and production development planning. Our patented cylinder treatment options ensure consistent and reliable accuracy and stability of your specialty gas, even for very low level sulfur components. These products are perfect for use in petroleum geochemistry, compositional analysis and sulfur compounds speciation. 

Subsea work

Air Liquide supports a range of products and services for offshore operations, including: inspection, maintenance and repair (IMR), diving, subsea welding and hyperbaric chambers.

Underbalanced drilling

Underbalanced drilling aims at maintaining the drilling fluid at a pressure lower than that of the surrounding formation. It offers several advantages as compared to conventional drilling methods, as well as a set of unique operational challenges.

Air Liquide offers a range of industrial and specialty gas solutions to help maximize both safety and efficiency in underbalanced drilling operations, from high pressure nitrogen production technologies for inerting and well injection to stable isotope pure gases and gas mixtures designed to maximize information obtained from wells. Our turnkey offer allows us to optimize our service quality and boost our customers’ performance while minimizing complexity and risk.
