Tullow Oil wanted to deploy a lighter well architecture for their upcoming drilling campaign on their Jubilee Field in Ghana, West Africa. The lighter architecture would remove the standard surface casing and run a combined surface/technical casing, after the conductor pipe had been jetted in place. The operator had concerns that, should there be cement shortfall and the conductor pipe cannot support the axial load, the combined string could fail from high bending stresses generated by excessive buckling. H&P’s Drilling Engineering Advisory team performed an in-depth study that considered several sensitivities related to the well architecture, cement shortfall, hole over gauge, and expected load cases. A stiff-string torque, drag & buckling model allowed the contact forces, deflected shape and Von Mises stress to be assessed along the casing string length. The conclusion of the study produced a refined well architecture that could lead to reducing the operational time by 5.1 days, saving $4M USD and 620mT CO2e per well.
