perezeo - What to expect?
The ContextAs drilling operations become more challenging geologists, operators and engineers need new ways to improve operational efficiency, increase production, reduce NPT and minimize risks.
Current methods of data acquisition rely on wireless data transfer technologies (mud pulse & electromagnetic transmission) ineffective in downhole transmission media conditions. On their own these technologies cannot achieve the speed or volume of data transfer required for modern downhole operations and subsurface evaluations. And currently these technologies can only transfer data from the BHA and the status of the wellbore is currently unknown as measurements can not be acquired along the drillstring.

57,000 bits/sec Simultaneous data High bandwidth High definition High Volume Real timeTool actuation
Broadband Network: What it MeansProvides high-speed, high-volume, high-definition, bi-directional broadband data transmission that enables downhole conditions to be measured, evaluated, monitored allowing tool actuation in real time.
Enables instantaneous transmission of full datasets from measurement tools in the bottomhole assembly and for the first time all along the drillstring
Delivers drilling engineers and geologists get all the facts in real time and are able to make fast, accurate decisions and solve potential problems as they happen.
Offers redundancy for existing telemetry systems,reduces trips for failed pulsers and increased tolerance to LCM or inconsistent mud
Enables industry experts to clearly see things they couldnt see before and achieve results like never before through a synthesis of broadband data transfer, measurements and operations

Downhole Network bandwidth 57,000 BPS Allows full logs in real time
Reduced Downlinking and Survey time, No need to pump to obtain data
Improved tool diagnostics Bi-directional downhole network provides full time connectivity
Better ECD managementAnnular Pressure data sent uphole every 5 seconds.
Pulsed data as a back up if network goes downBoth systems operate simultaneously
redundant telemetry system,less trips for failed pulsers, telemetry issues due to LCM and inconsistent mud, BHA sensors and failed tool POOH's, diagnostics, bore hole stability issues etc.. for Drilling engineers*Stress that this is Trinidad*Stress that this is Trinidad*Stress that this is Trinidad*Stress that this is Trinidad*Stress that this is Trinidad*
