Application of Advance Seal AS in Deepwater Drilling

This case study details the deployment of the Baker Hughes Advance Seal AS lost circulation material (LCM) in a deepwater drilling campaign off the coast of Brazil. The drilling operation faced challenges due to high reservoir pressures and the need to maintain well integrity while minimizing fluid losses in a pre-salt carbonate formation. The DCF team designed a bridging material to effectively control circulation losses, which was tested in the lab before being applied in the field. The deployment resulted in a significant reduction of fluid losses, maintaining stability in the wellbore, and achieving high acid solubility for effective cleanup. The application saved approximately $900,000 in fluid costs and potentially up to $3 million in related rig and logistics expenses. The successful implementation of the Advance Seal AS LCM demonstrated its effectiveness in challenging drilling conditions, providing valuable insights for future applications in similar environments.
