BoreSentry utilizes multiple nodes along the drill string to allow for optimal hole-cleaning, reduced risk of stuck pipe, and borehole stability issues, all while providing enhanced influx and loss visibility.
The Network’s flexibility is also easily adaptable to enable third-party measurements transmitted through XACT’s network. XACT has also proven transmission of data through a closed BOP confirming the availability of a multi-location, real-time downhole measurement data stream, even during well control situations when the annular preventer or bore rams are activated. The network’s bi-directional transmission capability opens a spectrum of enhanced downhole actuation and control possibilities.
|Example Operation||Typical Issues||Applied Acoustics with XACT||Well Construction Efficiency||Integrity Assurance||NPT Reduction||Production Optimization|
|Drilling Complex Wells||Unknown wellbore conditions and stability between BHA and surface||Along string annular pressure, weight & torque for hole cleaning and drillstring mechanics, kick detection and monitoring||x||x||x|
|Drilling Deep Wells||High telemetry failure rates and low data rates particularly at depth or in heavy muds||Complete redundancy and order of magnitude increase in bandwidth with interface to MWD/LWD to enable more efficient well construction||x||x|
|Managed Pressure Drilling (UBD/DGD/MPD)||No downhole data during connections, tripping and only from BHA No data during total losses||Data in previously unavailable environments, including annular and bore pressures during connections, while tripping and distributed along the drillstring||x||x|
|Well Control||Annular pressure at bottom of hole often masked from subtle influx changes. No pressures during well control with closed BOP||Along String annular pressure for accurate monitoring of influx, constant pressures straddling the shoe during low / no flow rates and below a closed BOP||x||x||x|
