Oil & Gas

Oil and natural gas are major industries in the energy market and play an influential role in the global economy as the world’s primary fuel sources, they are crucial to the global economic framework, impacting everything from transportation to heating and electricity to industrial production and manufacturing. The processes and systems involved in producing and distributing oil and gas are highly complex, capital-intensive, and require state-of-the-art technology. The industry is often divided into three segments: Upstream: Oil and gas exploration and production Midstream: Transportation, storage, and processing of oil and gas. Downstream: Refining and marketing. All the segments requires the precision, reliable and high stability instrumentation for process and control, to ensure the safety of the entire system operation, as well as accurate production and monitoring.
