Intro
Horn Mountain is a deepwater truss spar production platform in the Gulf of Mexico, installed in 2002. It produces oil and gas and serves as a host for multiple subsea tie-backs, acting as a regional hub for nearby developments. The platform is moored in deep water and connected to export pipelines.
Field
The Horn Mountain field is located in Mississippi Canyon, Gulf of Mexico, producing from Miocene turbidite sandstone reservoirs. The field is moderate in size and consists of multiple reservoir compartments typical of deepwater channel and fan systems, with additional nearby accumulations tied back to the host.
Facilities
Horn Mountain utilises a truss spar platform supporting subsea tie-backs via steel catenary risers. Subsea wells are connected through manifolds and flowlines, with production routed to topside processing facilities. These include oil and gas separation, gas compression, and produced water treatment. Oil is stabilised and exported via the Mars Oil Pipeline system, while gas is compressed and transported through offshore gas networks. Produced water is treated prior to discharge. Subsea infrastructure includes electro-hydraulic umbilicals for control and chemical injection. Power is generated onboard using gas turbines. The spar configuration provides stability and supports multiple risers, enabling efficient handling of production from several fields and facilitating future tie-backs.
