V. Read the passage and mark the following gaps as true (T) or false (F).
The natural gas industry is at an all-time high. This is largely due to shale gas. Before, extracting
gas from shale formations was expensive. Also, shale gas was considered a marginal source of
natural gas. However; hydraulic fracturing (fracking) combined with horizontal drilling has
changed that. Shale gas is now a substantial source of natural gas. Drilling for shale gas is more
cost-effective than before. Fracking takes place in a drilled well. Chemical additives like hydrochloric acid are injected under high pressure into the rock bed. The pressure cracks the rock. The chemicals widen the cracks and create channels. Natural gas escapes through the channels into the well. From there, it is extracted to the surface.


1 _______ In the past, shale gas was not cost-effective to extract.
2 _______ Fracking is another name for hydrochloric fracturing.
3 _______ A drill creates channels in the shale rock bed.
