SUGAR LAND, TX--(Marketwired - Oct 22, 2013) - Written by John Egan for Industrial Info Resources (Sugar Land, Texas) -- Three years after the lifting of a moratorium on deepwater oil & gas exploration, the Gulf of Mexico is humming with drilling activity, part of a worldwide trend of finding and extracting hydrocarbons at ever-deeper ocean depths. The Gulf is not the only region seeing a surge of deepwater and ultra-deepwater exploration, but it is the world's most active spot for that type of drilling, with more than 500 wells operating and many more scheduled to be brought online in the next few years.
