How do Blowout Preventers (BOPs) and Choke Manifolds Work Together?

Blowout preventers and choke manifolds are two of the most important systems in pressure control during drilling operations. These components aren't just essential—they are inseparable when it comes to safe and efficient well control. Their collaboration helps crews manage unexpected pressure surges, prevent dangerous blowouts, and maintain operational stability under intense conditions. This article unpacks their coordination in real-world drilling environments, showing how timing, function, and flow regulation align to protect both people and equipment.
