SHALE OIL: FORMATION, EXTRACTION AND THE BOOM THAT FOLLOWED
Shale oil, a significant player in the global energy landscape, has revolutionized the oil industry over the past few decades. This article delves into its formation, extraction methods, and the transformative boom it has sparked. Formation of Shale Oil Shale oil originates from organic-rich sedimentary rock formations known as shale. These rocks, deposited over millions of years, contain kerogen—a precursor to oil formed from organic matter such as algae and plankton. Unlike conventional oil reservoirs, shale oil is tightly trapped within the shale formations, requiring advanced extraction techniques to unlock its potential. Oil Shale (Source: Tehran Times) Extraction Methods Extracting shale oil involves complex processes due to the geological characteristics of shale formations. The primary extraction techniques include: Hydraulic Fracturing (Fracking) : This method involves injecting a high-pressure fluid mixture (typically water, chemicals, and sand) into the shale formation.
