In the past decade, fiber-optic (FO) -based sensing has opened up opportunities for in-well reservoir surveillance in the oil and gas industry. Distributed-temperature sensing (DTS) has been used in applications such as steam-front monitoring in thermal enhanced oil recovery and injection-conformance monitoring in waterflood projects. FO-based pressure gauges are deployed commonly. Significant progress also has been made in maturing other new FO-based surveillance methods such as distributed acoustic sensing (DAS). In this paper, the authors present a recent example of single-phase-flow profiling with DAS.
Introduction
FO-based surveillance allows for a complete, instantaneous data set from the top to the bottom of the well vs.
