1. Broadband Networked Drill String Unlocks Operational Performance Potential by Transmitting Downhole Measurements in Real Time Authors: Daan Veeningen, Jesus Saenz, Ron Weegman, NOV IntelliServ

2. Talking Points What is the Context? What is the Technology? What is the Approach? What is the Impact? Summary and Thoughts

3. 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.

4. Broadband Network: The Technology Mud Pulse 10 bits/sec Sequential data Data transferred in 2-5 sec pulses Continuous bi-directional data transfer gamma resistivity pressure vibration IntelliServ Broadband vibration Sonic Image Logs Etc, Etc 57,000 bits/sec Simultaneous data High bandwidth High definition High Volume Real time Tool actuation

5. 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 couldnt see before and achieve results like never before through a synthesis of broadband data transfer, measurements and operations

6. Approach to Deploy the Broadband Network Develop a clear understanding of the design of the well, equipment specifications, data transfer requirements and the clients objectives to ensure the data transfer system is configured right from the start. Include information about downhole data acquisition requirements Configure Provide secure and reliable tool shop-tested connections which are designed to connect with all major service providers equipment in standard protocols. When deployed IntelliServ will provide daily reports of network status and connection monitoring to ensure optimum and robust data transfer Connect 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 theyve never had access to before, and ensuring they always get the facts about downhole events Acquire Provide high-quality, bi-directional data transfer in high-definition and at a faster rate than ever before to customers in any location, from at- surface to town Transfer 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 Actuate
