Question

The Marcellus shale is:

a. A major new source of coal that was deposited in the bottom of an ocean without oxygen a long time ago.
b. A major new source of gas that was sitting there right under everyone’s noses and all you had to do was drill in and suck out the gas.
c. A major new source of oil that had leaked into the rocks from sandstone layers above and below.
d. A major new source of gas that has become available because people developed the technological tools to recover the gas.

Answer 1

Answer:

Option D is correct.

The Marcellus shale is: a major new source of gas that has become available because people developed the technological tools to recover the gas.

Explanation:

The largest natural gas-producing region in the United States, accounting for close to one-fifth of the country’s total gas production is the Marcellus shale.

This shale has emerged as one of the most cost-effective gas plays, given the high production rates of wells in addition to improving drilling efficiencies being brought about by the appropriation of technologies such as pad drilling.
