Paper Abstract

A fiber optic pressure and temperature (P/T) gauge has been designed and qualified for use in the harsh environment of downhole oil and gas applications. This paper will discuss the design and qualification testing of the Bragg grating-based gauge. Testing included pressure and thermal cycling over the operating range of 20,000 psi and 200°C along with Highly Accelerated Life Testing (HALT). To date, the P/T gauge design has been used in hundreds of installations globally. A brief description of the applications for the P/T gauge will also be discussed.
