WHAT IS BASIN MASTERING AT TOTAL?
ESRI HOUSTON PUG 2019 2
● Geoscience knowledge capitalization● Spatialization and GIS integration● Play map generation (up to date)● Maturing plays and prospects● Risk and uncertainty of plays
● Adapted to TOTAL’s hub-based regional exploration organization
MENA-CSE: Middle East, North Africa, Caspian and Southern Europe
Africa
MENA-CSE
North Sea-Russia
Asia-PacificAmericas
Exploration Hub
WHY WORKING ON BASIN MASTERING?
ESRI HOUSTON PUG 2019 3
Total Exploration works worldwide in regional Hubs The need to share the same workflows and standards
People change position every 3 years Sharing data & knowledge is eased by Basin Mastering
Fully integrated in the validation process for acreage acquisition and drilling
Total is facing a massive retirement of experienced people A tool to gather and store their knowledge
BASIN MASTERING: HOW DO WE DO IT?
ESRI HOUSTON PUG 2019 4
● Create regional GIS projects in form of Play Element Maps
● Place prospects into their regional context
● Locate, identify, and mature new plays
● Provide key input to Yet-To-Find estimates
This is Total’s exploration knowledge base

Fictive Data
Play structural elements• Normal Faults (square)• Thrust Faults (teeth)• Folds (arrow ends)• Salt Bodies
Outlines regimes• Extensional Coast• Compressional Shelf
Data Adequacy Inlay• Provides a view of the
quality and resolution of the data
• Helps us understand how much trust we can have on the map’s data
• Often the data comes from multi million dollar 2D/3D Seismic datasets
HOUSTON: BRAZIL – PRE-SALTSALT SEAL PRESENCE AND QUALITY
ESRI HOUSTON PUG 2019 11
Fictive Data
• Good example of regional play elements with large accumulations of high quality commercial oil
• By stacking Seal, Reservoir, Structural and Charge maps we can determine if the different plays are suitable for further exploration
• Shows local variations of salt thickness
• When more salt is present a better hydrocarbon Seal is present
• Pock marks on the dataset are an effect of the data having higher resolution
Water Depth:approx. 3000m
HOUSTON: US ALASKA - COLVILLE BASINRESERVOIR PALEOGRAPHY
ESRI HOUSTON PUG 2019 12
Fictive Data
• National Petroleum Reserve in Alaska
• Shows depositional systems and domain environments as when the reservoir was being deposited (past)
• First Domain environments are mapped: Basins, Shelf, etc. then we map the depositional environments: Deltas, Lobes, Fans, etc.
• The Delta Plain here is similar to a river that deposited and filled the basin from west to east
• Sources come mainly from public sources using our standards
ESRI HOUSTON PUG 2019 13
CONCLUSION AND OUTLOOKBasin Mastering has now been in place for 2 years
Used by all Explo teams using the same standards
Main Gains:
• Allows for data & knowledge transmission
• Knowledge is updated often with new data/insights
• Improves consistency in our evaluations
• Eases the decision making process
• Generates new ideas
