Piston-like plugging of fuzzy-ball workover fluids for controlling and killing lost circulation of gas wells
During well-killing operations for the workover of low-pressure gas wells, formation pressure should be balanced so as to guarantee well control safety by preventing natural gas overflow. In this paper, a laboratory evaluation was conducted with fuzzy-ball fluids as killing fluids. The results show...
