bMark™ global data and benchmarks were deployed to hunt for hidden value in a mature offshore oil field with a complex reservoir & production history

Background:

• Complex 1000MMbbl offshore oil field with 20 years history
• 12 fault blocks & 5 reservoir horizons generated 60 separate reservoir pools which had been developed across multiple platforms
• Huge variance in development efficiency across different reservoir pools with multiple drive mechanisms deployed

Project Highlights:

• bMark™ used to rapidly organize disparate field data spreadsheets into a single reference project file
• Recovery Factor benchmarking conducted at field, fault block & reservoir pool level
• Aggregate analysis conducted, quantifying impact of varying drive mechanisms across different pools (see image)

Result:

• Operator model of production allocation challenged in key reservoirs, leading to re-think of fault connectivity assumptions
• Under-developed reservoir pools highlighted
• Potential upside resource quantified at >80MMbbl
• Project completed in < 2 weeks
