Wellbore
In maritime context, wellbore refers to the hole drilled in the seabed for the purpose of exploring, drilling, and producing oil and gas from offshore reserves. It is a cylindrical hole that is drilled vertically or at an angle from a fixed platform or a floating vessel. The wellbore is lined with steel casing to prevent collapse and to isolate the well from surrounding formations. It is also cemented to provide zonal isolation and to prevent the migration of fluids between different geological formations. The wellbore is a critical component of offshore drilling operations and requires careful planning, design, and execution to ensure safe and efficient production of hydrocarbons.
