What’s the fuss about

Stewardship
Gunther Newcombe OGA April 2016
Production Data 101
Focus on Allocation
Fluid Dynamics
Reservoir Engineering Handbook, Tarek Ahmed, Elsevier 2010
How confident are you in well allocation
figures?
Confident or Very Confident 45%
Unconfident or Very Unconfident 55%
An inkling of a problem…..

Data Maturity
Production Data
Maturity Chart
Non-existentOrganization has no data governance approach, does not understand the need for governance and has no stewardship functions.
Ad hoc
Organization performs occasional, non-standardized stewardship activities but has no formal data governance approach.
Standardized
Organization has implemented some standard data governance practices and has standardized the stewardship role.
Committed
Organization has instituted formal data governance for all business units and has dedicated stewards for all business units.
Consolidated
Data governance and stewardship are coordinated across the enterprise, involving business and information technology and management in partnership.

Data is in
excel hell

What’s wrong with spreadsheets?
Manual data entry error
Broken links to other sheets
Not stored centrally – c drive common
Poor collaboration
Non QC’d algorithms
Version Control non existent
Poor security
No compliance with regulator

Two steps
1. Create a common data store
2. Automate the processes
Plot the data flow

Our journey
PDMS is the basis for better science
WELL RATE ESTIMATION EXTERNAL PROSPER MODELS
INPUT PROCESS OUTPUT
Fire -up Latest Prosper Model
Run Lift Model
Run IPR Model
Allocated Rates - qg
PI Process - Pth, Tth data
Well flowing bottomhole pressure (Pwf)

Estimated Rates: Store & Plot
Use Prosper modelling to estimate rates?
PDMS forces set Roles &
Responsibilities
PDMS challenges our assumptions
Our Flow Meters
Historical data in EC
Anaysis of past data
Excel – the Return
Let in the Light
• Scale change time saving for
engineering processes
• Seconds to run reports, not hours.
• Improved Allocation consistency
between HAC and PE's
• New workflows now
