The shale revolution transformed the United States from an importer of crude oil to a net exporter, revolutionizing the world’s energy landscape.

摘要

The shale revolution transformed the United States from an importer of crude oil to a net exporter, revolutionizing the world’s energy landscape. The success of the shale revolution is due to the abundant shale oil and gas resources in the United States, but technological advances such as horizontal Wells and staged fracturing have also played a crucial role in this! Faced with the challenges of shale oil development, shale oil operators in North American adhere to the principle of “Testing-Before-Development” and have scientifically organized and implemented multiple hydraulic fracturing field tests, continuously deepening their understanding of the fracturing process and promoting the development of fracturing technology, thus igniting the “shale revolution”. In the reported hydraulic fracturing field tests of shale oil in the United States, the hydraulic fracture network and stimulated reservoir volume (SRV) experiment conducted by ConocoPhillips and the hydraulic fracturing test site (HFTS) project have had a profound impact on fracturing technology. These tests took several years to understand the hydraulic fracturing process through advanced diagnostic monitoring technology and observations of rock cores traversed by hydraulic fractures, detecting the reservoir state before and after fracturing and during production, promoting the formation of shale oil development concepts and technological innovations such as tight cutting, extreme perforation, and variable rate fracturing (VRF) centered on “effective stimulation of well-controlled reservoirs and full recovery of well-controlled reserves”. Based on the introduce of testing reports on ConocoPhillips SRV, HFTS-1, and HFTS-2, this paper discusses and summarizes the important results obtained from these tests in the hydraulic fracturing process of shale oil reservoirs. The development trend of shale oil fracturing technology has been proposed, and relevant suggestions have been put forward for achieving high production by low wells, reducing environmental impact, and improving economy in shale oil development.
