2 Agenda Automation What is DSATS? Objectives DSATS Communication Team (Comms Team) Phases Where can IADC DCS help? 2

3 Definitions Automation (Wikipedia): Automation is a step beyond mechanization. Whereas mechanization provides operators with machinery to assist them with the muscular requirements of work, automation greatly decreases the dependency on human sensory and mental requirements as well. 3 Excerpt from M. Mannering s SPE DSA-TS Panel Presentation 3

4 Shell Cliffdale Asset, Peace River In 2009, a Shell-engineered SCADA system was installed on a hydraulic rack-and-pinion rig. It integrated the control and data acquisition systems of: Top Drive Mud Pumps Electronic Data Recorder MWD (un-manned) Flow Meters Slide courtesy of Shell Two multi-lateral oil production wells were drilled in closed-loop autonomous fashion, with the SCADA system controlling the entire rotary and slide-drilling process from slips-out to slips-in, without driller intervention. This included automatically generated trajectory steering commands. 4

5 SPE Drilling System Automation Technical Section Facilitates the development and implementation of emerging automation technology Representation in the Society s activities Advanced Technology Workshops Forum Series meetings Distinguished Lecturer program Organizing technical sessions at conferences Effective liaison with other players in the field Appropriate publicity in journals such as JPT. 5

6 SPE Drilling System Automation Technical Section Supports initiatives to communicate the technology, standardizes its nomenclature and helps define its value proposition. Identifies lessons learned and best practices associated with the accelerated uptake of Drilling Systems Automation and, if appropriate, facilitates the development of standards. 6

7 DSATS Comms Team Recommends guidelines to allow open and secure communication between: Rig control systems Applicable surface and downhole measurements Authorized third parties 7

8 DSATS Comms Team Deliverables Broken into four phases: Phase 1 Identify and define key interface points to equipment on rig Agree upon a list of tag names for the key interface points for use in communication protocols Agree upon at least one open communication protocol between components 8

9 Phase 1: Equipment Interface Points Control System Interface Mud Pumps Primary Drawworks Autodriller Top Drive Drilling Choke Drilling Recorder Data Aggregator Authorization Feedback RT Data Status Descriptions o o Limits General Control / Set points Health 9

10 Phase 1: Communication Protocol OPC UA (Unified Architecture) ( Microsoft has deemphasized COM in favor of cross-platform capable Web Services and SOA (Service Oriented Architecture) OPC Vendors want a single set of services to expose the OPC data models (DA, A&E, HDA...) OPC Vendors want to implement OPC on non-microsoft systems, including embedded devices Other collaborating organizations need a reliable, efficient way to move higher level structured data 10

11 DSATS Comms Team Deliverables Phase 2 Architecturally significant use cases Define components of architecture High level roles and responsibilities of the system components 11

13 Phase 2: Simplification What do I need to automate the simplest rig? 13

14 Phase 2: Simplification What do I need to automate the simplest rig? Automation Console For Driller Authorizes / Disconnects Starts / Stops Displays Alarms / Status DCD Translates Generic to Rig Specific Firewall to Rig Control Enforces Limits Monitors Health Only one agent in charge of automating a piece of equipment at one time Is this sufficient? 14

15 Phase 2: Simplification Another layout Sensors Sensors Hoisting System Top Drive <Rig Contractor> 6 6 Hoisting Control System Hoisting Control System HMI Composite Control System HMI System: Independently exposes automation interface. Can expose new automation capabilities. 8 Sensors Mud Pump Generic 3 rd Party Data Aggregator Composite Control System 7 Comms Device 5 Automation Control System HMI Router/Switch Company A Control System Company B Control System

16 Phase 3 & 4 Phase III Identify and define industry terminology necessary to enable process automation for drilling of oil and gas wells Define interface for components (e.g. limits management, authorization, alarm & events, etc.) Phase IV Define commissioning tests (starting conditions, procedure, and expected results) for each component.

17 Where can IADC DCS help? Driller regaining control sufficient? Automation Console devoted to authorization, monitoring, and disconnecting automation This can be integrated with driller s console (if desired) Big red button

18 Where can IADC DCS help? Best way to transition automation control between service companies? <Rig Contractor> System which switches is the Comms Device. Manual? Automated? Not at all? (Disconnect/Connect) 8 Sensors Sensors Sensors Hoisting System Top Drive Mud Pump Generic 3 rd Party Data Aggregator Hoisting Control System Composite Control System 7 Hoisting Control System HMI Comms Device 5 Composite Control System HMI Automation Control System HMI Router/Switch Company A Control System Company B Control System

19 Where can IADC DCS help? Alarms Too many? Levels and actions (e.g. NATO drones use 7 levels) Notifications Fail-safes

20 Where can IADC DCS help? Mechanization Integration Automation Denver Smart, Emerson Are there other pieces of equipment that can be brought closer to automation? DSATS-Comm initial focus: Control System Interface Mud Pumps Primary Drawworks Autodriller Top Drive Drilling Choke Drilling Recorder Data Aggregator

21 Where can IADC DCS help? Are there contractual issues to be reviewed relating to the contractor s and operator s role? (Terry/Mike to follow up.)
