Subsea Drive Riserless Casing Drilling System
The Subsea Drive System is proven liner‑drilling technology applied in riserless drilling environment.
The system is specifically designed for the large, heavy casing strings used in deepwater
Applies the principles of casing drilling simultaneously drilling and running casing
Mitigates shallow drilling hazards with wellbore strengthening and a smaller annulus
In a single trip casing is run to the seafloor, drilling the structural casing to a depth determined by the prevailing pore‑pressure / fracture‑gradient
The system replaces current practice of jetting enabling a significantly deeper set of the first casing string
Increasing Deepwater Well Value
Significant improvement in deepwater well integrity and value by deepening the structural casing for dual function:
structural conductor
increased shoe strength set in stronger formations
Allows fewer riserless casing strings
Creates Larger hole and casing annuli below
Optimizing Anchor Resistance Capacity
Provides superior anchoring properties with anchor set beyond current practices with increased setting depth using conventional oilfield cementing practices
System Features
No wellhead or rig modifications
Retrievable casing running tool
Inner-string cementing system
Drillable casing bit
