2 The Industrial Internet of Things (IIoT) M2M

3 Wireless Sensor Networks Enhancements Since initially being introduced, manufactures have: Introduced more robust communications Hardened Security Increased Reliability Driven down Power Consumption

4 Why Wireless Sensor Networks? Up to 10X less expensive Engineering Installation Logistics Faster start ups Accelerated profits

5 What is a Wireless Sensor Network? A network of end nodes communicating information gathered from the sensor back to a gateway. Star Topology Mesh Topology Gateway End Node

6 Wireless Sensor Network End Nodes Pressure Flow Temperature Level Discrete

7 Wireless Sensor Network (WSN) Applications Upstream Midstream Downstream

8 WSN Applications Tank Levels Variety of Technologies Resistive Product and Interface Magnetostrictive Hydrostatic Ultrasonic Radar

9 WSN Applications - Pressure Casing Tubing Surface Flow Line Level

10 WSN Applications - Flow Well Injection Custody Transfer Variety of Instrumentation Differential Pressures Turbine Positive Displacement Ultrasonic Coriolis

11 WSN Applications - Temperature Flare Monitoring Liquids Gases Vapor Recovery Units Compressors Typical Instrumentation Thermocouples RTD

12 WSN Applications Valve Actuation Valves play a key role in oil & gas production and are vital in providing safety to personnel and mitigating risk from any environmental impact. Applications range from plunger control to Emergency Shut Down (ESD) to shut-in a well in the event of abnormal process conditions preventing a spill or catastrophic environmental incident.

13 WSN Applications - Environmental In order to conform to more and more regulatory initiatives regarding greenhouse gas emissions, a wide range of wireless sensors are being used. The EPA has proposed a suite of requirements to reduce methane and VOC emissions from O&G production with the Climate Action Plan.

14 The Digital Oilfield

15 Powering Wireless Sensor Networks Most WSN Solutions provide acceptable battery life Some IoT applications require higher duty cycles Trade off is required (update rates vs. battery life) While utilization/functionality of WSN has increased dramatically over the years, battery technology has not improved at the same rate.

16 Energy Harvesting Is the process of using ambient environmental sources like sun, wind and vibration and converting them into usable electrical energy. Leads to perpetual operations with: Increased performance Increased Duty Cycle

17 Energy Harvesting With the global market for Industrial wireless sensor networks expected to grow at a Compound Annual Growth Rate (CAGR) of 12.96% from 2014 to 2020, much needed innovation is required. Energy harvesting is seen as one the of the key areas that advancements need to be made simply because replacing batteries is not feasible. Markets and Market, Industrial Wireless Sensor Networks Market worth $ Million by 2020 press release.
