Answer:
Step-by-step explanation:
Shale oil and gas wells have contributed to the recent dramatic increases in oil and gas production in the United States. The development of hydraulic fracturing (fracking) techniques in the 2000s allowed for the extraction of previously unreachable resources from shale rock formations, resulting in a significant increase in domestic oil and gas production. Deepwater traditional oil wells, Canadian oil sands, and conventional natural gas wells have also contributed to the increase in production, but the development of shale oil and gas wells has had the most significant impact.
