Enhanced-Gravel-Pack Completions Revitalize a Mature Sand-Prone Field

摘要

Production from the Dulang oil field began in 1991.In the later stages of field life,a significant amount of sand production caused well and platform shutdowns.A study begun in 1999 to revitalize the field identified sand control as a requirement for the targeted reservoirs.Because a sand-control installation would result in an increase in mechanical skin,a combination of sand control and a stimulation technique was determined to be the best approach for production optimization.The combined strategies have increased productivity and prevented sand production.
