Description
Continuous Well Monitoring Using Distributed Temperature Systems
In the industry, temperature logs are obtained by logging wells with thermal sensors. These discreet sensors are point sensors, typically either deployed at fixed depths or dipped in. Distributed temperature sensing systems (DTS) allow continuous monitoring of wells over the length of the well and are used as permanent monitoring systems, dip-in logs, and diagnostic tools.
DTS are optoelectronic interrogators that provide a continuous temperature measurement along optical fibers. DTS systems send laser light down a fiber and analyze embedded signals in the light to derive temperature information. The sensor is the fiber itself, which is deployed in the well by various methods. Aside from the top-side interrogator, DTS systems do not have any electronics, electrical wires or electrical connections along the line, thus making the system intrinsically safe for harsh environments.
This presentation will cover the applications of DTS, the various types of DTS techniques, choices of fibers for the specific environment, cable configurations, and environmental impacts to consider before deploying a DTS system. The presentation will also cover single-ended vs dual-ended interrogation techniques and data correction techniques. Also discussed will be data interpretation and case histories demonstrating how these techniques have enabled operators to monitor and diagnose well behavior, analyze temperature data, make operational decisions and apply corrective actions as needed.
