The Aquaterra Energy Low-Pressure Overshot has been designed to support low-pressure riser top hole drilling activities. The Overshot provides a safe and effective method of fluid and pressure containment on any API cut casing or conductor profile and a means of connection to the drilling unit’s diverter system or riser. The overshot can be deployed both at the surface or subsea, having a manual drive bolt or alternative hydraulic seal activation.

In my last blog, I explored how vertical and horizontal subsea trees influence intervention planning, access routes, and operational efficiency. In practice, subsea well access is shaped by more than tree architecture. That brings us to a critical operational distinction: pressure control versus well control. Although these terms are often used together, they represent two […]
