Award Nomination Recognizes OptaSense for Improving Hydraulic Fracturing Safety
OptaSense, a QinetiQ company and global leader in distributed acoustic sensing (DAS), has been recognized for its contribution to improving the safety of hydraulic fracturing. OptaSense’s DAS Hydraulic Fracture Profiling (DAS-HFP) service has been selected as a finalist for the World Oil Award in the Best Health, Safety, and Environment/Sustainable Development Onshore category.
The DAS-HFP service is used within hydraulic fracturing operations where OptaSense technology is used not only to improve the operational efficiency of hydraulic fracture stimulation but also to provide a real-time monitoring capability to verify well integrity.
OptaSense helps operators manage unplanned events such as flow behind casing, casing leaks and ruptures, casing collapse, and isolation failures between stimulation stages. This not only has economic value for optimizing a hydraulic fracturing program but also delivers significant value for environmental monitoring of fracture fluid breakthrough into other subsurface formations and freshwater aquifers because of wellbore barrier failure.
Currently, the American Petroleum Institute (API) regulatory guidelines state that the internal conduit of the well must be isolated from the surface and subsurface environments. However, conventional technologies are typically limited to pressure measurements at the wellhead and are inadequate for real-time detection and characterization of most failures other than catastrophic ones.
By contrast, the OptaSense DAS system provides a means to measure and monitor the performance of these barriers directly from wellhead to toe continuously and in real time. The system is used to detect, localize, and characterize barrier failure. It also detects fluid communication behind casing, casing collapse, and leaks through or between casing strings, many of which go unnoticed by conventional monitoring methods.
The World Oil Award nomination recognizes that the real-time data OptaSense delivers provides invaluable information to operators, greatly minimizing the environmental cost of a leak by early detection.
Magnus McEwen-King, OptaSense managing director, said, “It is an honor to be recognized alongside the major service companies in one of the industry’s most prestigious awards. Our DAS-HFP service is just one of several services provided over fiber-optics that improve the efficiency and safety of hydraulic fracture operations. Distributed fiber-optic sensing has the potential to provide monitoring throughout the life of the well. The ability to monitor the whole wellbore continuously enables operators to confirm wellbore integrity and better understand, diagnose, and correct sources of failure to improve operational effectiveness.”
The winners of the World Oil Awards will be announced at the ceremony held at the Houstonian Hotel in Houston on 16 October.
