Abstract:
A lost circulation system and a method for reducing losses of drilling fluid in a lost circulation zone of a wellbore are described. The lost circulation system includes a sheet of lost circulation material and particles of a lost circulation material. The sheet of lost circulation material has a maximum thickness of 1 millimeter, a length of one foot to one thousand feet, and a width of one inch to twenty inches. The method for reducing losses of drilling fluid in a lost circulation zone of a wellbore includes identifying the lost circulation zone, deploying a sheet of a first lost circulation material in the wellbore at the lost circulation zone, and circulating a slurry containing particles of the lost circulation material through the wellbore.
