Instrumentation and gas analysis for oil & gas

The complexity of oil and gas drilling and extraction operations requires the installation ofreliable measurement and analysis instruments (gas analysis, flow measurement, pressure measurement, temperature measurement) . Optimal control of equipment, even in extreme environments, ensures the reliability of processes and guarantees the longevity of offshore or onshore platforms.

Choosing the right instrumentation can help protect the environment by detecting or stopping leaks or by making oil and gas transport and storage operations more reliable.

Oil extraction

Conventional oil

ONSHORE OIL FIELD

Crude oil is recovered by drilling into oil reservoirs, and lifting the oil if a blowout does not occur.

OFFSHORE OIL FIELD

In offshore exploration, a platform is built to drill wells and extract oil.

In deep wells or in the event that the reservoir pressure is not sufficient to raise the oil to the surface, the oil is lifted by injecting high water pressure. Reliable measuring instruments are essential to ensure the safety of our installations.

Unconventional oil

OIL SHALE

Shale oil and oil shale gas are extracted from oil shale, either thermally or chemically, or by hydrogenation.
An estimate in 2013 shows that the world's total oil shale resources are worth 6.7 trillion barrels, four times more than conventional oil. The largest deposit of resources in the United States.

OIL SANDS

As the crude oil in the tar sands is extremely viscous and cannot be extracted by a conventional process, high temperature steam is injected to lower the viscosity of the oil in order to recover the oil.

Gas production

A gas well is created by drilling a borehole 3,000 to 5,000 meters deep, placing casing in it, and making holes on the casing in the gas zone so that gas can pass through the holes in the well. drilling. Then a steel pipe called a production tube is inserted into the casing to carry the oil or gas to the surface. In most cases, oil and natural gas include contaminants such as strata water and carbon dioxide. To remove them, oil and gas are sent through a valve assembly called a "Christmas tree" to a separator.

Unconventional natural gas

SHALE GAS

Shale gas is natural gas present in shale formations. Due to its low permeability, it cannot be recovered by conventional drilling methods. In recent years, the natural gas industry has adopted horizontal drilling and hydraulic fracturing in the extraction of shale gas.
Shale gas has become an important source of natural gas, particularly in the United States and Canada.

GASEOUS FUEL

Liquefied natural gas (LNG) and liquefied petroleum gas (LPG).
