The Context
As 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.

Broadband Network: What it Means
• Provides 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 couldn’t see before
and achieve results like never before through a synthesis of broadband
data transfer, measurements and operations
Approach to Deploy the Broadband Network
Configure
Connect
Acquire
Transfer
Actuate
• Develop a clear understanding of the design of the well, equipment
specifications, data transfer requirements and the client’s objectives to
ensure the data transfer system is configured right from the start.
Include information about downhole data acquisition requirements
• Provide secure and reliable tool shop-tested connections which are
designed to connect with all major service provider’s equipment in
standard protocols. When deployed IntelliServ will provide daily
reports of network status and connection monitoring to ensure
optimum and robust data transfer
• Enable data to be acquired from the BHA and for the first time all
along the drill string, providing customers with a unique opportunity to
explore new sets of data which they’ve never had access to before,
and ensuring they always get the facts about downhole events
• Provide high-quality, bi-directional data transfer in high-definition and
at a faster rate than ever before to customers in any location, from atsurface to town
• Enables our customers with two-way, high-volume data flow to
explore new levels of Tool Actuation and provides an ability to
reconfigure, recalibrate and diagnose during drilling operations which
means costly trips can be avoided
Impact: Recently Established Facts (Single Well)
• Fault imaging at 100ft/hr in 17 ½” hole – Modifying well trajectory
• Dip picking in real time – Improving structural understanding
• Stick slip in real time – Modifying drilling parameters and extended
hole section
• Tool memory filled Up
• Wellbore breakout imaging – Caliper in real time
• Diagnosed sensor failure – Drilling Ahead
• Conclusion: More data
saves time to interpret
