Archer has launched the VIVID™ acoustic listening platform — a patented, highly sensitive, acoustic technology that detects, investigates and locates leaks in real-time, verifies cement barrier seals and characterizes downhole events with unparalleled precision. The announcement was made at the SPE/ICoTA Coiled Tubing and Well Intervention Conference and Exhibition 2018 following an intensive program of field testing conducted globally.
The VIVID™ platform consists of full-spectrum acoustic sensors that accurately measure the broadest frequency bandwidth and amplitude of acoustic energy with industry-leading sensitivity and can even locate previously indiscernible low energy leaks. Developed by Archer’s Research and Development team and independently-tested, VIVID™ will play a key role in casing and completion evaluation, cement performance evaluation and turbulent flow analysis.
Key applications for VIVID™ include:
• Casing and completion evaluation with the acoustic technology able to detect leaks while logging dynamically in the presence of road or surface noise; characterize leak responses in gas and liquid, and gas bubble flow; locate gas migration behind casing that was previously below detection thresholds and identify cross flow behind perforations.
• Cement performance evaluation with VIVID™ determining the sealing quality of the cement; evaluating flow in the presence of micro-annuli; and establishing minimum flow levels through a cement barrier.
• Turbulence mapping where turbulent flow can be mapped in real-time with VIVID™’‘s full broadband spectrum and sensitivity supporting production flow characterization and mitigation of completion damage.Click here for a VIVID™presentation
