Sand control succeeds in high-rate,big-bore gas wells

摘要

Sand production is avoided offshore by employing expandable sand screens in horizontal holes that utilize big-bore casing.The result is high-rate output of gas and condensate.A two-well,subsea tieback of the high-rate Echo-Yodel gas-condensate field was successfully drilled and completed offshore Australia in 2001 by operator Woodside Petroleum.
