10 Technology What is it? 03 July

11 Definitions - Automation Increased focus on maintaining a stable operation level and have sustainable high performance in operations. This combined with reduced manning to save cost, keeps the focus on automation in our industry high. The term automation, inspired by the earlier word automatic (coming from automaton), was not widely used before 1947, when Ford established an automation department. [1] It was during this time that industry was rapidly adopting feedback controllers, which were introduced in the 1930s Typical example of every day Automation Make / break function for our Hydraulic Roughneck RNX

12 Definitions Industrial Robotics Industrial robotics is a sub-branch in the industrial automation that aids in various manufacturing processes. Such manufacturing processes include; machining, welding, painting, assembling and material handling to name a few. Industrial robots utilizes various mechanical, electrical as well as software systems to allow for high precision, accuracy and speed that far exceeds any human performance. Typical example of Robotics Foto: RDS.no

13 Definitions - Digitalization Continuous feedback on progress, planned well construction vs actual drilled well, health status and performance of operation from the Drilling Factory back to other supporting and relevant systems is a natural evolution within digitalization. Typical example of every day Digitalization Digital maps used in navigation apps

14 Technology What is Virtual Reality (VR) and Augmented Reality (AR)

15 Definitions Virtual Reality In 1938, Antonin Artaud described the illusory nature of characters and objects in the theatre as "la réalité virtuelle" in a collection of essays, Le Théâtre et son double. The English translation of this book, published in 1958 as The Theater and its Double,[4] is the earliest published use of the term "virtual reality". The term "artificial reality", coined by Myron Krueger, has been in use since the 1970s. The term "virtual reality" was used in The Judas Mandala, a 1982 science fiction novel by Damien Broderick.

16 Definitions Augmented Reality Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data. It is related to a more general concept called mediated reality, in which a view of reality is modified by a computer. Typical example of every day Augmented Reality Pokémon Go

19 Drilling System Platform DSPx 03 July

20 Drilling Ecosystem Simulation Seismic Geology Drilling Well Program Drilling System Time based Always inaccurate Large deviation from plan Depth based Slow loop hr/day s Small deviation from plan Planning Domain Interface & Service Domain Predictive models simplified Fast loop ms/sec Drilling process DSPx

21 Data collection and OPEN sharing Today, we do not control the entire chain we need to integrate to automate System integration handle data from different stakeholders and share Collection Top-side data Down-hole data BOP data Oil companies Sharing data RL Drilling MPD data Drilling contractors RL Drilling Equipment vendors Mud/mix data Directional drilling data MWD data Service companies 03 July

22 Technology Platform and Smart Modules Based on 15 years of experience our technology is easy to extend through use of Smart Modules that are based on our Drilling Equipment Automation Layer and Open Interface. Drilling Equipment Automation Layer (DEAL) - Interface to equipment control system - Maintains safety and security - Separation between control system and Smart modules. - Install new Smart modules without affecting the control system. - Easier deployment and roll-back. Stay out of trouble Slide 22

23 Technology Platform and Smart Modules Open Interface - Enables 3 rd party Smart Modules - Two way communication - Examples: Well plan, hydraulic modules, simulation, well protection modules, ROP modules, etc. Integrate - one common system - remove silos Slide 23

24 DSPx - also for robotics and equipment 3 July, 2018 Slide 24

26 List Of Deployed ADC Smart Module DEAL Drillers Assist DrillTronics What Drilling Equipment Automation Layer Guides the driller with well construction and protection Dynamic calculated values for Drillers Assist Benefit Single interface for Smart Modules Consistent & efficient well operations and well safeguarding Real time limits and operational envelope reflecting current well conditions EKD Early kick detection Alert driller early when a kick or loss is detected Soft Torque Z 3 rd generation Stick Slip Mitigation Reduce vibrations in the drill string. Reduce wear of bit and achieve a higher ROP 03 July

27 DEAL - (Drilling Equipment Automation Layer) Provides interface to Smart Modules and devices controlling MHWirth equipment Allows integration of 3 rd parties Can add new Smart Modules without changing machine control system Has safety and integrity functionality built in to avoid Smart Modules affecting the drilling system outside predefined boundaries Ready for Rheology integration 03 July

31 Smart Modules Supporting Services and Technologies Pre-study: DrillTronics Integration Into Driller s Assist There is a potential for reducing well cost, both through increasing efficiency and reducing NPT. The driller will be able to focus on fewer and the most important parameters and allow for quicker response and correct actions. Early response is a key issue to reduce consequential damages.

35 Daily report from Enabler July 3,

36 Early Kick Detection (EKD) Alert the driller early of kick/loss situation No configuration Machine Learning based Monitors same data as driller is watching Adapts to the well Detects kick/loss earlier than driller Active during connection 03 July

37 EKD - How? 1. Models expected: Flow out Standpipe pressure Gain/loss volume 2. Compare modelled with measured 3. Raise kick/loss alarm if deviation between measured and modelled is too large 4. Machine learning during drilling Update parameters in models Expected behaviour of more complicated relationships Human EKD 1. Based on experience and current well conditions has an expected value of main parameters 2. Compares expected values with measured 3. If deviation is too large detect possible kick/loss 4. As well is drilled and new measurements Update expected well parameters in 1) 03 July
