For over a decade now, operators in the US Gulf of Mexico have been in pursuit of equipment and technology suitable for the safe development of ultra-high-pressure reservoirs; those requiring up to 20,000 psi operating pressures. The Kaskida discovery was the first in this category, discovered by BP in May 2006 and is understood to have logged pressures as high as 30,000 psi. Over the next eight years, we count at least as many more ultra-high-pressure discoveries with estimated total recoverable reserves to be nearly 2.4 billion barrels equivalent.
