Case Studies

Discover how Belltree Consultants have used bMark™ to augment their technical expertise, resulting in maximum client value and unique insights

National Scale Benchmarking

Belltree’s expertise in development and deployment of machine-learning driven predictive benchmarks was deployed to help the UK Oil & Gas Authority better understand the remaining potential of the North Sea



  • In February 2014 the Sir Ian Wood Report “UKCS Maximising Recovery Review” identified the requirement to benchmark recovery efficiency, production efficiency, production costs & decommissioning costs in the UKCS

  • Benchmarking was recognised as a key pre-condition to first understand the potential future improvements and then provide a measure against which to assess progress

  • Belltree was appointed to develop the Recovery Factor benchmarks for the UKCS based on our expertise in benchmark development

  • Project scope included >400 fields spanning the Northern North Sea Oil Fields & Southern North Sea Gas Fields


Project Highlights:

Knowledge Classification

  • Full audit & collation of OGA database

  • Issues identified including:

    • Key data outdated or missing

    • Averaging / aggregation errors

    • Inconsistent naming between multiple sources

  • bMark™ analogue trends leveraged for Infill / Quality Control

  • Improved database delivered to client

  • Improved data collation recommendations provided


Benchmark Development

  • Two separate predictive benchmarks developed for Northern North Sea Oil Fields & Southern North Sea Gas Fields

  • OGA analysis using the oil benchmark indicated a combined +900MMstb potential from 26 underperforming fields

  • Benchmarks analysis used by OGA to set aspirational targets and guide detailed conversations with Operators



Unique Due Diligence Insights

bMark™ global data and benchmarks were teamed with Belltree’s expertise in technical due diligence to support a corporate takeover of assets in Norway



  • Belltree was the lead technical due diligence provider integrated with a  corporate due diligence team from an international name-brand firm

  • We were representing a buyer considering a corporate takeover involving 39 assets offshore Norway

  • The seller’s mixed portfolio contained mature producing fields, discoveries under development and exploration prospects

  • All fields (including 20+ years of data for mature assets) were to be assessed in less than 5 weeks


Project Highlights:


  • Belltree quality-checked the Seller’s technical assumptions using the bMark™ database, leveraging it’s high-density Norwegian field dataset alongside relevant international analogues

  • Belltree identified systematic  “optimism” in the Seller’s predicting of recovery factor for yet-to-be-developed fields. Suitable discount factors were generated with bMark™ benchmarks and Seller production profiles downgraded for the fair market value calculation

Asset Due Diligence

  • Exploration & Facility risk assessments

  • CAPEX / OPEX forecast validations

  • Independent reserves assessment



  • Project delivered resulting in successful corporate acquisition

  • Sale price negotiations impacted positively for our client based on bMark™ benchmarking

  • Project completed in < 5 weeks
