Challenge: Convert the reservoir into
underground gas storage (UGS), and use openhole completions to limit sand
production
Solution: Custom design a reservoir drill-in
fluid and a filtercake breaker system that removes filtercake uniformly,
enabling injection and production through the entire horizontal interval
Results:
- Exceeded customer expectation in gas production
- Produced lower-than-expected drawdown pressures
- Incorporated BREAKDOWN enzyme and chelant filtercake breaker system
into gravel pack fluid for intimate contact with filtercake
- Cored 102.5-m interval with full recovery
