This is a first in the history of ONGC; The Vivekanand-1 Team has overcome the challenges of a very critical well with severe mud losses; 1000 to¬†2000BPH. The BH# 6 well’s critical design parameters presented unique hazards jeopardizing the well stability and potential environmental hazards. The Vivekanand-1 team along with Cementing Services Team have successfully cemented the BH#6 developmental well’s 9 5/8′ casing as per plan with high-performance lightweight cement slurry. This extreme operation required all team members dedication and hard work to achieve success. This historical event gained recognition from General Manager Drilling- Mr. Ajay Kumar Sharma- “The Cementing Services and Vivekanand-1 teams did an excellent job”. Along with “Congratulations for successful¬†operations” from Mr. N Rajendren Karaikal- Chief Engineer Drilling.
