SCADA Monitoring and Control / Automation SCADA – Supervisory Control and Data Acquisition •  Pick the right SCADA Host / Software

–  Internally Hosted vs. 3rd Party Hosted (eLynx)

•  SCADA / Automation Personnel –  Internal Hire vs. Contract

•  Plan for the future:

–  Scalable, Repeatable, Manageable, Upgradeable, and Cost Effective

Communications Types of Radio Networks

•  Serial Radio Networks –  Internally Owned / Managed –  Licensed –  Low Throughput –  High Power / Long Range

•  IP Radio Networks –  Multi-Threaded –  Internally Owned / Managed –  Unlicensed –  High Bandwidth / Throughput –  Low Latency –  Lower Power / Shorter Range

•  Cellular / LTE Networks (Verizon, AT&T, iNet, TEN, etc.) –  Multi-Threaded –  Externally Hosted – Can be secured through VPN / APN –  High Bandwidth / Throughput –  Limited Coverage –  Least Capital Intensive

•  MQTT (Message Queueing Telemetry Transport)

–  Developed by Andy Stanford-Clark and Arlen Nipper in 1999

–  State Aware

–  Amazon IoT based on MQTT

–  Used by Facebook Messenger

•  Message-Oriented Middleware (MOM)

Communications Report by Exception vs. Poll Response

•  Poll – Wait – Response

•  Poll Frequencies

•  Data Usage –  Assume 3 Messages, 50 byte Request 200 byte Response = 750 bytes per Poll Cycle

•  (Doesn’t account for other overhead)

CONFIDENTIAL Robert Warren Well Site Automation Conference 2017 13

Communications Report by Exception vs. Poll Response - Comparison

•  Alarm Configuration

•  Communication Failure Notification

•  Exception Notification Delay

–  Response Time to Incident

CONFIDENTIAL Robert Warren Well Site Automation Conference 2017 14

Operations by Exception Focus on Value Creation

•  Reduce Downtime

•  Increase Production

•  Target Artificial Lift –  ESP –  Rod Pump –  Gas Lift –  Plunger Lift

CONFIDENTIAL Robert Warren Well Site Automation Conference 2017 15

Operations by Exception Creating an Operations by Exception Culture

•  Senior Leadership Buy-in and Support –  Trust

•  Lease Operator Buy-in –  Communication / Set Expectations –  Training –  ***Success Breeds Acceptance and Excitement***
