  • Permanent downhole temperature sensing succeeds for low cost wells

    D. Simonits and A. Franzen

    Oil and gas producers continuously face the challenge to optimize output and reduce operational costs further. For a decade, permanent, optical inwell monitoring systems have gained increased acceptance in upstream production operations. However, so far, mostly highend and, therefore, usually complex (mainly deepwater) wells were the focus for these socalled intelligent completions. Large investments for the surface equipment, installation complexity, and the lack of standard tools for efficient data gathering and analysis, were the main reasons for the general hesitation toward this technology. A major breakthrough is still awaited. In a cooperative effort between Shell International Exploration and Production (SIEP) and LIOS Technology GmbH (LIOS), the feasibility and economic added value of permanent downhole temperature sensing have been successfully demonstrated in a number of recently deployed on and offshore projects in Brunei. This article presents the generic design and implementation of an exemplary case study for permanent downhole, Distributed Temperature Sensing (DTS)
