Optimize drilling time in shallow waters of Mexico
Successful 30-in casing drilling for exploratory wells in Tertiary formations led to the design of the first 34-in Direct XCD drillable alloy casing bit. The ultimate goal was to implement casing drilling in conductor sections of wells with robust well schematics, targeting Mesozoic formations. Using drillable alloy casing bit technology in the 30-in × 34-in conductor section would ensure the settlement of the 30-in casing in a single run, thus optimizing well construction time by drilling and casing the hole simultaneously to achieve the planned well design in less time.
Provide time-saving drilling solution with Direct XCD bit
To optimize the operation and the drilling time needed for the conductor sections of the exploratory wells, the operator and Schlumberger performed a technical feasibility study to analyze the viability of deploying the 34-in Direct XCD bit.
