Fiber Optic monitoring services include a portfolio of distributed and point sensors used to evaluate wellbores from unconventional and mature field markets to heavy oil thermal and deep water environments. FiberWatchdistributed temperature and acoustic sensing provide evidence of fluid movement along the wellbore throughout the well life. FiberPoint? sensing provides accurate pressure and temperature measurements within the wellbore to improve evaluation of fluid movement over time. Fiber optic conveyance is also critical to consider. SPECTRUMSM Diagnostic Service and FiberLog? retrievable services as well as permanently deployed and pumped fiber applications each provide unique strengths with respect to fiber conveyance to fit the need for any downhole application.
FiberWatch DTS Hydrogen Tolerant (HT) System
The FiberWatch DTS hydrogen tolerant (HT) system is designed to provide DTS results in the harshest upstream environments. This system incorporates our patented dual-laser technology to mitigate effects of degradation to capture meaningful data on multi-mode fiber that may have previously been unusable. The interrogator is designed for long-term monitoring to assess life of well performance.
FiberWatch Distributed Temperature Sensing (DTS) Single Laser (SL) System
The FiberWatch DTS SL (single laser) system is a proven and tested design that has been deployed globally and proven to work in almost any environment. The single laser system has been adopted as a more cost efficient option for collecting reliable DTS results. This system also has a working range up to 15km.
FiberWatch DTS Single Mode (SM) System
The FiberWatch DTS SM (single mode) system is designed to provide reliable and confident DTS results specifically for single-mode fiber. This solution works in all markets from unconventional, mature fields, heavy oil, to offshore. This FiberWatch DTS SM system incorporates our patented dual-laser technology to mitigate effects of degradation and eliminate the need for double-ended measurements.
FiberWatch Distributed Acoustic Sensing (DAS)
Pinnacle, a Halliburton Service has successfully deployed fiber optics in over a thousand wells worldwide and provided valuable information to customers in various challenging environments. This includes covering markets from unconventional resources and mature fields to harsh thermal environments in heavy oil plays. FiberWatch Distributed Acoustic Sensing (DAS) is based on Rayleigh scattering principles used to determine acoustic strain signals over long distances, effectively turning the optic fiber cable into a series of virtual microphones. Once the data is acquired, advanced processing techniques such as frequency filtering, time and depth domain stacking, etc. can be applied to obtain information for a wide variety of applications.
Applications
StimWatch Injection Flow Profiling;
FlowWatch Production Flow Profiling;
Leak detection / Wellbore integrity monitoring;
Cross-well Analysis.
Features
Real-time data analysis;
Robust field ready unit;
FiberView visualization software.
Pinnacle DAS Advantage
Halliburton acquired Optiphase to further develop the acoustic sensing arm of our industry leading fiber-optic product line. This acquisition has enabled Pinnacle to work closely with manufacturing to enhance the hardware performance. To complement industry acquisition, Pinnacle has developed FiberView? software suite for real-time optical visualization for both DTS (Distributed Temperature Sensing) and DAS interpretation. From manufacturing and operations to data acquisition and analysis, our teams are focused on delivering a complete product that provides real value.
StimWatch Injection Flow Profiling
Our industry leading DAS solution provides real-time monitoring of injection fluid, to assess fluid entry points and fluid distribution along the wellbore. Halliburton’s ControlFracSM service allows operators to assess diversion effectiveness, such as Halliburton’s AccessFrac service solution, and determine cluster efficiency in real-time. As with other applications, this service utilizes DAS and DTS as complementary tools to confidently define fracture fluid distribution. This approach applies to a broad range of strategies including plug and perf stimulations, packer/sleeve completions, waterflood, and acid injection.
FlowWatch Production Flow Profiling
DAS is used as a complementary tool to improve understanding of flow distribution along the entire length of a producing wellbore. It is commonly used in collaboration with DTS to interpret and define flow allocation throughout the life of the well. DAS is now a mature technology that provides true diagnostic value across several applications, production analysis included.
Leak Detection/Wellbore integrity monitoring
DAS has been successfully used to pinpoint leaks in casing and production tubing. This technology is providing real value at identifying leak locations and saving significant time and resources to locate leak locations from other means. It has been used to identify leaks due to casing failure, tubing failure, and completion tool failure.作者: 铁木真 时间: 2023-12-17 03:32
