Case study

Well intervention strategies for production enhancement

Challenge

A national oil company needed to increase production from mature brownfields at a profitable cost, but conventional workflows could not identify and rank intervention candidates across thousands of wells quickly, or predict post-job performance reliably.

Solution

An automated production enhancement system covering candidate identification and ranking, AI-driven prediction of post-job well performance, and closed-loop evaluation of job outcomes.

Results

Validated in two giant brownfields with more than 3,000 active well strings and over 1,400 workovers a year.

  • Over 80% predictive accuracy in blind tests
  • 5–20× more feasible high-value opportunities than manual review
  • 250,000 barrels of oil per day of incremental production
  • 17% less CAPEX to achieve the production uplift
