Gas which is unaccounted for in a transmission system. Since meters are accurate to about 1% if one meter is located at the entry point and one at the exit point accuracy reaches up to 2%, but UAC gas is often less than this

Flexible connecting sheath, containing flexible pipes and cables. An assembly of hydraulic hoses which can also include electrical cables or optic fibers, used to control subsea structures from a platform or a vessel.

A new type of drilling rig, such as the one ordered by BP Exploration Alaska to drill in the Liberty field in the Beaufort Sea off Alaska, nearly 2 miles deep and with offsets as long as 8 miles. BP will own the land-based rig and will use it to drill as many as six extended-reach wells into Liberty field beginning in 2010. One of the design requirements of the rig was the ability to drill wells out to 8.3 miles (43,824 ft).

New generation of drilling rigs to be commissioned around 2010. These are drilling ships designed to drill in water as deep as 12,000 ft

Between 6,000-10,000 feet. As fields are discovered in ultra deepwater (6,000 – 10,000 ft), the oil and gas industry is searching for floating production systems (FPS) that can economically develop those fields. Choosing the right FPS depends on the water depth, hull motions, and the type of riser system desired
