Q. What is this “tight oil” ?
Answer: It is a crude oil that is found in petroleum-bearing shale formations that have relatively low porosity and permeability
Notes: Tight oil refers to crude oil extracted from shale formations with low porosity and permeability, making it difficult to extract using traditional methods. This type of oil is often produced through hydraulic fracturing (fracking) and horizontal drilling techniques. The U.S. has seen a important increase in tight oil production, particularly from formations like the Bakken and Eagle Ford, contributing to the country's energy independence. Tight oil is considered unconventional due to the advanced extraction methods required.
