Durable memory-based tool records more data

摘要

While traditional real-time tools often use crystal-based sensors to accurately measure pressure and temperature downhole, a new memory-based tool uses improved strain-gauge technology that measures more downhole parameters with high accuracy and more durability. Advances in technology have greatly increased the success rate of coiled tubing (CT) operations in most regions of the world. One of the biggest advances in CT in recent years is the development of high-powered sensors that record forces on the tubing string more accurately. Real-time tools often rely on crystal-based sensors, which are capable of reading temperature and pressure within a range of 003% accuracy. While the sensitivity of crystal-based sensors is well established, they are typically more expensive, which can increase operating costs. In addition, crystal-based sensors are not robust and can be easily damaged in operations where heavy impacts are commonplace.
