The annular manifold typically consists of the following key components: 1. Main Body: The main body of the annular manifold is usually made of durable materials such as steel or alloy. It is designed to withstand high pressures, corrosive environments, and harsh operational conditions encountered in oil and gas wells. 2. Inlet and Outlet Ports: The annular manifold features multiple inlet and outlet ports that allow for the connection of different pipes or equipment. These ports enable fluid flow control and distribution to specific locations within the wellbore. 3. Valves and Chokes: Valves and chokes are often integrated into the annular manifold structure. They provide operators with the ability to regulate fluid flow rates, pressure levels, and divert flow to desired areas of the wellbore. 4. Instrumentation and Control Systems: Annular manifolds can be equipped with instrumentation and control systems to monitor and manage fluid parameters such as pressure, temperature, and flow rates. This helps optimize well operations and ensure safe and efficient fluid handling.
