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

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

“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.”

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

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.

DSATS Comms Team

Recommends guidelines to allow open and secure

communication between:

• Rig control systems

• Applicable surface and downhole measurements

• Authorized third parties

7

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

Phase 1: Communication Protocol

• OPC UA (Unified Architecture) (www.opcfoundation.org)

• 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

DSATS Comms Team Deliverables

• Phase 2

• Architecturally significant use cases

• Define components of architecture

• High level roles and responsibilities of the system components

11

Phase 2: Starting

Architecture

OPC UA – Connects all

automation components

• Equipment Interfaces

• DCD

• Aggregator

• Driller’s Console

• External Interface

Phase 2: Simplification

What do I need to

automate the simplest rig?

13

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

14

Is this sufficient?

Phase 2: Simplification

Another layout…

System:

• Independently

exposes automation

interface.

• Can expose new

automation

capabilities.

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.

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…

Where can IADC DCS help?

• Best way to transition automation control between service

companies? <Rig Contractor>

• Too many?

• Levels and actions (e.g. NATO drones use 7 levels)

• Notifications

• Fail-safes

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

Where can IADC DCS help?

• Are there contractual issues to be reviewed relating to the

contractor’s and operator’s role?
