Oil and natural gas are found in two different varieties, conventional and unconventional. Conventional oil is liquid crude oil. Conventional natural gas is free untrapped gas. Each can be found uniquely. Both can be found together. Colonel Drake struck conventional oil with a well drilled to a depth of 69.5 feet at Titusville, Pa., in 1859. On April 20, 2010, the Deepwater Horizon was two days away from temporarily capping an oil well in the Gulf of Mexico it had drilled more than six miles deep in 4,130 feet of water. During the disconnection process the rig suffered a blowout.
