ABSTRACT of Presentation
Downhole sensing technology today provides engineers continuous measurements for flow condition diagnosis. The measurements include temperature, pressure, acoustic, and strain, with Distributed Temperature Sensors (DTS) and Distributed Acoustic Sensors (DAS) being more commonly used than other measurements. Since optical fiber technology was first introduced to the industry, it has advanced dramatically.
Many field applications have proven fiber optics to be effective and beneficial. From downhole flow condition characterization, we can diagnose flow problems, monitor, control, and optimize production & injection well performance, monitor well stimulation - both matrix acidizing and hydraulic fracturing - and optimize treatment designs. There are rich field application examples to show the potential of the technology. One of the keys to applying downhole sensing technology is to develop models and methodologies that interpret the sensor measurements. This is challenging because data collection and processing, model development, and converting the measured parameters to flow profiles is extremely mathematically and computationally intensive.
In this lecture, we will review the current status of downhole sensing technology, explain the available models and approaches for interpretation, and present field application examples including production profiling, horizontal well flow control, matrix acidizing optimization and multi-stage hydraulic fracture diagnosis. The lecture is based on publications by the author and other SPE publications. The lecture illustrates the power of DTS as a tool for production problem diagnosis and well performance optimization.
