Drilling Fluid and Completion Fluid | Year: 2014

The Structure No.1 of Nanpu, an artificial island, has found formation pressure depletion because of long period of production. Mud losses have been a major problem for safe and economic drilling operation. A high performance LCM slurry, which is aimed at controlling mud losses under pressure, is recently developed. This LCM slurry uses large bridging particles, flake LCM NTS-M and NTS-S and fiber LCM SQD-98 as well as sized packing LCM in a certain mass ratio, can hold pressures up to 7 MPa in laboratory test. Mud losses in well Nanpu 13-1170 was completely controlled at the first use of this LCM slurry, and subsequent jobs such as casing running, cementing were all successful. Source
