Honeywell sensors and switches are an essential element in today’s oil and gas industry, used for many types of upstream applications such as exploration, well development, and production. They need to be built tough to survive some of the world’s most demanding environmental conditions, both on land and offshore, while providing accurate and reliable performance. Well stimulation (fracturing and acidizing), mud logging, and well development (casing and cementing) are vital oil and gas processes that utilize Honeywell sensors and switches for measurement, control, and monitoring functions.
