What is DrillTronics?
/ DrillTronics is- An extension of the Drilling Control
System (DCS) to ASSIST the Driller- Providing safety envelopes, safety
triggers and automated functions
Driller can decide to override at any time
/ It is not- It is not a control system (in the
sense of controlling one or several parameters)

Feedback loop protects wellbore and ensures well objective is achieved
/ Pack-off prevention function protects wellbore
/ DrillTronics detects pack-off 7 minutes before driller reacted and took action

Statfjord C – October 2014
/ First well - Several examples of increased efficiency, consistency in operations - Safeguarded well against human mistakes
/ Drillers especially liked the automated functions and the ability to measure consistency and improvement in connection time and tripping speeds
3/30/2016 / 12 / Copyright © 2016 Sekal AS. All rights reserved.
/ Longest lateral well ever drilled on Statfjord C, 8400m, 12 1/4” section
Statfjord C – July 2016
CONTROL TO PERFORM
ANALYZE TO ADJUST
SIMULATE TO OPTIMIZE
Learnings after seven wells
TECHNICAL / Excessive testing prior to use – certified in
well simulator
/ Changes and upgrades to systems are limited after installation
/ New concept challenging old systems –processes and procedures
/ Lack of standard for updating & reporting data changes
OPERATIONAL / The importance of training
/ Focus from equipment failure to examining wellbore condition
/ Awareness throughout the drilling organization creates good communication
/ Expectations need to be set with all parties –communication
/ Align processes to avoid imposing too many changes in the operation and in the team

Statfjord C – DrillTronics on all wells
/ All teams performs equally as good as the best driller/ Consistently amongst Statoil top performers
MAKES AUTOMATIC DRILLING POSSIBLE
