Distributed fiber-optic pressure sensors for application in oil and gas industry

This paper shows the current state of measurement systems in oil and gas industry. The advantages of fiber-optic sensors over the classical ones are demonstrated. The possibility of creating a system of distributed fiber-optic pressure sensors is considered. It is proposed to use the physical properties of optical fiber and the impact of cable microbending on the back reflection effect. The ways to increase the attained laboratory layout specifications are set out.
