What is Subsea Exploration?
Subsea is a term frequently used to refer to equipment, technology, and methods employed to explore, drill, and develop oil and gas fields that exist below the sea bed. This can be in either “shallow” or “deepwater”, where deepwater is used for subsea projects located in water depths greater than 300 metres, and may include floating drill vessels, semi-sub rigs or semi-submersible platforms. “Shallow” or “shelf” is used for shallower depths and can include standing Jackup Rigs or similar. Subsea production systems can range in complexity from a single satellite well with a pipeline linked to a fixed platform, FPSO or an onshore installation, to several wells on a template or clustered around a manifold, and transferring to a fixed or floating facility, or directly to an onshore installation.
