IntelaTrac in ChevronDownstream and Upstream
Operator routine duties (ORD) is a term used in many places
Chevron employs ORD in the Downstream, and seven years ago implemented IntelaTrac
– Some of you know Eric Rearwin who helped roll out IntelaTrac in the Chevron operated refineries
– Eric has been a popular speaker in several venues and has helped me in my ORD journey
Chevron uses ORD in the Upstream as well, and selected IntelaTrac as the tool to enable this work process three years ago

IntelaTrac in ChevronUpstream
In the upstream, Operator Routine Duties are often connected with surface equipment
However, the term ORD has broader implications
Routine duties can be useful for collection of
Surface equipment data
Production related data
Regulatory compliance data
HES data
Operations & Maintenance Procedures
Commissioning check lists
And other settings where check lists are usedSources: www.chevron.com

IntelaTrac in the UpstreamRoutine Duties
Paper-based Routine Duties
Routine duties are found in most upstream oil & gas operations
They are often paper-based
– Check list with readings or observations
– Place to indicate if the condition was normal
– Place for the operator to enter any action taken
These are typically based on a set of standards
Electronic Routine Duties
Paper is good, but is a starting point, not a stopping point
Electronic routine duties marry:
– Operator driven reliability and enhanced operator routine duties
with…
– Enhanced surveillance and action for those “on the beach” and in the field office
IntelaTrac is a great tool to enable electronic operator routine duties

IntelaTrac in UpstreamRoutine Duties
Operator Driven Reliability
Routine duties for surface equipment typically include readings and observations
Each, value entered is evaluated against pre-defined tolerances specified by vendors, Operations, Engineering or Maintenance
If those tolerances are exceeded, follow up actions and questions are trigged and the operator is typically prompted for comments
Surveillance
Exceptions are flagged as a result of routine duties
The type of exception is pre-assigned to the condition along with a pre-defined severity
Exception reports may be automatically generated and sent to operation supervisors, area managers, specialized surveillance teams and other groups
With this visibility quick action may be taken

IntelaTrac in UpstreamRoutine Duties
Surface Equipment Examples:
Check suction pressure, if low (e.g., < 150 psig)
– Follow up action: instruct to check for restrictions in the inlet flow
Check discharge pressure, if less than inlet pressure
– Follow up action: instruct to open up a work order to replace the filter
– Display work order request window
Check crankcase oil level, if LOW
– Follow up actions:
• Instruct to add oil and indicate brand and viscosity
• Instruct to add note indicating how many quarts were added
• Display note window

IntelaTrac in UpstreamRoutine Duties
Surface Equipment Examples:
Check compressor discharge gas temperature, if high (>300 degF)
– Follow up action:
• Ask a follow up question: “Are the louvers closed?”
If YES, follow up action: instruct operator to open louvers
• Ask a follow up question: “What is the water level in cooler?”
If LOW, follow up action: add water
• Ask a follow up question: “is valve temperature high?”
If YES, follow up action: call mechanic
• Ask a follow up question: “is gas recirculation ON?”
If YES, follow up action: call mechanic
• If none of the above follow up questions were true
Follow up action: instruct Operator to shut down the compressor and call mechanic

IntelaTrac in UpstreamRoutine Duties
Production Data Examples:
Tank gauging
– Enter level, calculate volume using strapping table data, calculate and display stock tank change in inventory
Well test (2 or 3 phase)
– Enter duration, test volumes and calculate rates
Downtime
– Enter start and stop date and time, assign reason code(s)
Meter readings
– Enter current reading and calculated volume using prior
Chemical inventories and injection rates
Well operating parameters
Calculate and display produced oil, gas and water for the day

IntelaTrac in UpstreamRoutine Duties
Some routine duties are less frequent or on-demand
Data collected once a rotation
– 1 week, 2 weeks, 28 day rotations
– Day of week can vary by hitch
– During the hitch, check if the “once a rotation” checks have been done, if not, ask if they want to collect now, if not, skip and ask next time
Data collected once a week, month or quarter
– During the monthly routine duty, check if the quarterly checks have been done, if not, ask if they want to connect now, if not, skip and ask next time
Start up procedures with instructions and readings
– E.g., re-light boiler pilot
The advanced calculation engine in IntelaTrac 4.0 and 4.1 along with Decisions and hidden Tasks and Task Groups make these possible

IntelaTrac in UpstreamRoutine Duties
IntelaTrac version 4.x has proven to be good tool to enable upstream electronic operator routine duties
Earlier versions did not have the flexibility to do so
But Invensys listened and did a great job delivering advanced capabilities
We are still waiting for a few more capabilities, but they are on the road map for future releases

Lessons Learned
In an IntelaTrac project, the technology is easy (and fun)
The heavy lifting is in defining the “Information Architecture”
Good Information Architecture is key to deriving maximum value from an IntelaTrac / ORD project
Operator Driven Reliability
– What to capture?
– What tolerances to configure for each reading and observation?
– What follow up actions to take or follow up questions to ask if tolerances are exceeded?
Surveillance
– Which users need to see the metrics and exceptions?
– What will they do with it?
– How will the information be made available to the user?
– What is the correct system of record (SOR) for the information?

Lessons Learned (continued)
The exception reporting capabilities of IntelaTrac are powerful
There are different categories of IntelaTrac / ORD information stakeholders, for example
– Operational supervisors
– Mid-level managers
– Executive and leadership
A good best practice is to meet with stake holders early in a project
– Explain and demo Web Reports and Auditor Plus
– Explain the role and use of Data Filters and Severities
– Explore what kind of exception conditions stake holders want to monitor
This will also help shape what is collected and tolerances.

Wrap up
IntelaTrac is an enabling technology
The key to these projects is to not just focus on the technology
– Examine the work process and design changes to the to-be process
– Start change management efforts early in the project
– Do a thorough Information Architecture
– Develop skills with IntelaTrac so it can be configured and maintained once the project is complete
Invensys has been a good vendor-partner to work with
We appreciate their support
