Gulf of Mexico: Deep Oil and Gas Drilling

Reported at MarineLink - Transocean Drills Deepest Oil and Gas Well:

. . . Transocean crews on the Deepwater Horizon drilled the well to 35,050 vertical depth and 35,055 feet measured depth (MD), or more than six miles, while operating in 4,130 feet of water.

Transocean also holds the current world water-depth record of operating in 10,011 feet of water set while working for Chevron in the U.S. Gulf of Mexico.

The Deepwater Horizon, placed into service in 2001, is a dynamically positioned ultra-deepwater semisubmersible rig capable of working in water depths of up to 10,000 feet.

BP PLC has reported a giant Gulf of Mexico Lower Tertiary deepwater discovery that is also one of the world’s deepest wells.

Named Tiber, the well went to a total depth of 35,055 ft on Keathley Canyon Block 102 and found oil in multiple Lower Tertiary (Paleogene) reservoirs, BP said. The company didn’t disclose the depth or thickness of the oil column.

The company said Tiber, after appraisal to determine its size, should be larger than the 3 billion boe that BP expects to recover from its 2006 Kaskida discovery 45 miles to the southeast.
