Real-Time Interactive Remote Display of DTS and DAS Data for Well Treatment Optimization

Abstract

The value of data can be greatly enhanced if the data are available at the right location and in a timely fashion. This can be a particular challenge for the often considerable volume of data collected using distributed measurements such as Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS). In this paper we describe a novel solution using multiple levels of data reduction yielding data of different sizes and fidelity. These are then transmitted for viewing at the wellsite, in real time at a remote location, or subsequently for post-job evaluation. This approach is demonstrated using a case study of a well stimulation operation from the United States.

Application of Fiber-optic Temperature Data Analysis in Hydraulic Fracturing Evaluation--A Case Study in Marcellus Shale

“…The distributed acoustic sensing (DAS) is a fiber-optic downhole measurement sensitive to local vibration around the fiber (Dickenson, et al, 2016). DAS technology is based on the Optical Time Domain Reflectometry (OTDR).…”
