Intro
The Cleeton Wellhead tower (CW) is a fixed steel wellhead platform installed in 1987 as part of the Cleeton gas field hub in Block 42/29. It hosts wellheads and associated manifold systems for gas extraction. CW feeds raw gas via bridge links to the processing facilities on CPQ and compression on CC.
Field
Located in the southern North Sea’s Block 42/29, the Cleeton field produces from Permian Lower Leman Sandstone. The wellhead tower marks the primary fluid extraction point, drilled in conjunction with hub development to support gas flow to processing and export infrastructure.
Facilities
The CW platform supports multiple production well slots gathering gas from reservoir zones. Wellheads are manifolded with flowlines leading to CPQ for central processing. CW integrates safety shutdown valves, pressure monitoring, and chemical injection lines for hydrate control and corrosion management. Subsea and surface well controls ensure remote operation capabilities, coordinated with CPQ’s central control room. The structural design features fixed steel legs and topsides sized for wellhead and manifold systems. Flowlines and umbilicals connect CW to adjacent platforms. Utilities are minimal, focusing on well chemical storage, power distribution from CPQ, and communications. Safety infrastructure includes fire and gas detection, emergency shutdown valves, and lifeboats. CW’s role remains stable as the initial field extraction point tied into hub processing and compression systems.
