So far the discoveries are tracking the production curve of the Continental Shelf, where 40 billion barrels have been located since drilling began in the late 1940s.

FORBES: Going deep

Tim Probert, president of global business lines, says that horizontal drilling, a process in which a well is drilled down vertically and then angled around a curve to reach reservoirs from a horizontal angle that increases the well's exposure, is now 55% of Halliburton's total activity.
