VIVID®Acoustic Listening Platform and Ultra-High Sensitivity Sensors to Play Key Role in Casing and Completion Evaluation, Cement Performance Evaluation, Sand Detection and Turbulent Flow Analysis
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.
- Downhole sand detection in flowing wells using VIVID®’s powerful statistical sampling techniques to reliably separate flow induced noise from the time limited signal generated from particle impacts. In addition to simple impact counting to give relative sand rates, advanced processing allows total impact energy analysis to be performed which allows more complex zonal evaluation of the properties of produced sand.
