The current reductions in crude oil prices have created a major interest in methods which significantly reduce operating overhead and improve operational efficiency. The timing could not be better for advanced in-well permanent monitoring technology, such as Distributed Temperature Sensing, which can deliver on both of these requirements. This technology has now truly come of age, demonstrating long term reliability, high performance and application benefit in a range of production and injection well types.
An area of particular interest is the application of monitoring in horiztonal and advanced well completions. While allowing significant improvements in production and reservoir depletion, these wells have caused data-gathering disruptions for the operating entities. In particular, the options to perform well logging are much reduced, and the costs of performing a production log are extremely high. This is related to both the costs of the more advanced horizontal well-logging tools and the more expensive logging methods—such as coiled-tubing and tracker systems—used to convey these tools into the wellbore.
Distributed Temperature Sensing (DTS) allows closure of this monitoring gap. In line with advancements in this technology, Sensornet and FloQuest have developed a real-time digital flow-profiling system, which aids increased production, reduces operating costs and improves recovery. Digital flow profiling with DTS is used to determine distributed flow-allocation profiles in production and injection wells. The system combines DTS fiber-optic technology with software modeling and data-interpretation.
