What is Conductor Pipe Conductor pipe (also referred to as structural casing or surface casing) is the first and most critical casing string installed during offshore oil and gas drilling. Its role extends beyond simply penetrating the seabed: it establishes the mechanical stability of unconsolidated formations, isolates seawater zones, and creates a circulation path for […]

A drilling riser is a critical piece of subsea equipment that connects the subsea wellhead and blowout preventer (BOP) to the surface drilling rig or platform. Unlike conductor pipe, which is a permanent foundation element, the drilling riser functions as a temporary, pressure-containing conduit during drilling operations. Its primary role is to provide a continuous […]

Vacuum Insulated Tubing (VIT) – OCTAL Technical Overview Thermal-Control Tubing for Steam Injection, Heavy Oil Production, Deep water Wells & Geothermal Systems Maintaining temperature inside the well-bore is essential for a wide range of modern oil & gas and geothermal operations. Heat loss not only reduces production efficiency but also increases risks such as wax deposition, […]
