摘要：
A wellbore loss zone remediation method to reduce losses of drilling fluid in a lost circulation zone of a wellbore is described. The wellbore loss zone remediation method includes identifying a lost circulation zone in a wellbore, selecting a lost circulation fabric, selecting a lost circulation material for a slurry, disposing the lost circulation fabric in the wellbore, circulating the slurry in the wellbore, and determining if the lost circulation zone is remediated.
