1 Monitoring Cathodic Protection, Corrosion Rate and Pressure in Production, Gathering and Storages Jamey Hilleary Elecsys Corporation

2 Monitoring Combined Data Types in Production, Gathering & Storage Presentation Focus: Demand for More Field Data System integrity management Greater focus from DOT and PHMSA Risk management and personnel allocation Exception-Based Monitoring Solutions Exception-based communication model Focus on significant data Alarms & notifications Deployable anywhere Common Monitoring Applications Cathodic protection system monitoring Pressure monitoring Corrosion rate monitoring Q&A

3 Operational Issues & Concerns System Integrity Management Catastrophic leaks in Kansas, Texas, and California storage facilities Increased regulatory focus on gathering, storage, and production sites Increased public awareness and concern New PHMSA Rule Proposals Wells and Gathering specified parameters: Pressure/inventory Internal corrosion Cathodic protection More

4 Operational Issues & Concerns Risk Management Develop, implement and document: Data collection and monitoring processes Preventive and mitigative measures Personnel Allocation Physical site inspections Data analysis Demand for additional data and integrity management planning from more sites

5 Exception-Based Monitoring Why Exception-Based Monitoring Economic communication model Focus on significant data Timely and accurate data collection Alarms & notifications Report generation and analysis Significant data forwarded, unchanged data stored (all data available) Combined data-types (CP, pressure, and corrosion rate)

6 Exception-Based Monitoring Why Exception-Based Monitoring (Continued) Access to data on demand from anywhere Data disseminated directly to key users Alarms and notifications sent directly to responsible personnel Data availability to multiple users, departments, etc.

7 Exception Based Remote Monitoring Connect Via Cellular/Satellite Capture Remote Sites Analyze and Act

8 Focus on Significant Data Measure Frequently/Report Periodically Scheduled data reporting from field Alarms and notifications Communication flexibility Multiple Data Types and Users CP values from casings and piping Pressure/volume data Internal corrosion data

9 Emphasis on Data Availability Web-Based Data Access Two-way data access from authorized, web-enabled devices Alarms and notification delivery to users Communication flexibility Multiple Data Types and Users CP values from casings and piping Pressure/volume data Internal corrosion data

10 Exception-Based Monitoring Exception-Based Monitoring Model vs. Traditional SCADA Model Report by exception reduces amount of bandwidth needed Enables lower throughput communication paths to be used Extends the data acquisition footprint Allows control room to extend to web-enabled devices in the field Provides actionable data directly to the field technician

11 Remote Monitoring Applications Cathodic Protection System Monitoring Rectifiers/impressed current power sources Operational/compliance measurements GPS synchronized interruption Test Stations and Critical Bonds AC interference corridors Pressure Monitoring Pipelines and storage wells Corrosion Rate Monitoring Compatible with ER and LPR probes Displays metal loss and corrosion rate (mpy)

17 Alarms & Notifications Key Elements of Exception-Based Monitoring (the Exception in Exception-Based) Periodic, scheduled reports inform users the monitor system is operational Alarm override reporting alerts users of any significant change in status Notification of abnormal condition is sent via , text, or both to users Re-notification of unaddressed alarm conditions sent at scheduled intervals Actionable data availability in the field enables task prioritizing on a daily basis

18 Data Management Data Management Essentials: View data, access sites using any web-enabled device, from anywhere Display collected data in tabular and graphical form Organize data by group, site, alarm condition, or measured parameter Export data to any offline database Automate compliance reporting Use data for prioritizing projects and resource allocation Efficient data management is essential to meeting risk management expectations

19 Summary Key Take-Away Points: Increased public awareness and concern is fueling demand for more data Exception-based monitoring can be an effective alternative to SCADA Web-based monitoring increases data accessibility Current monitoring technology provides access to sites and data types previously unavailable Increased data accessibility improves resource allocation (budget, personnel, time) Comprehensive, timely, and accurate data is essential for system integrity and risk management
