Abstract:
A lost circulation system and a method for reducing losses of drilling fluid in a lost circulation zone of a wellbore. The lost circulation system includes a sheet of lost circulation fabric and particles of a second lost circulation material. The sheet of lost circulation fabric is a material whose structure and composition limit a flow of fluids, particularly drilling fluid, through the sheet. 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 sheet of the lost circulation fabric has holes extending through the sheet.
