OPEC and Market Influence The Role of Technology and Shale Technological advancements, particularly hydraulic fracturing and horizontal drilling, have revolutionized the industry by unlocking vast quantities of oil from shale formations in the United States. This distinction is vital because a large portion of the earth's oil is either too deep, too expensive, or too environmentally sensitive to be considered a viable reserve, even if the material physically exists.
