Cyclic steam stimulation (CSS), or "huff and puff," is a common approach where steam is injected for a period, then the well is shut in to allow heat to soak into the surrounding rock before production begins. They provide a reliable supply base that complements lighter crude grades, ensuring refineries can produce a full slate of petroleum products, including diesel and jet fuel.
Heavy Oil's Pivotal Role in Strengthening Energy Security
Resources with an API gravity below 20 degrees fall into this category, making them significantly thicker than conventional crude. Understanding its properties, origins, and market role is essential for energy professionals and stakeholders navigating the evolving energy transition.
This method involves removing the overburden to access shallow deposits of extra- heavy oil. The extraction processes, particularly surface mining and steam generation, can have a larger surface footprint and higher greenhouse gas emissions per barrel compared to conventional drilling.
Heavy Oil Role in Energy Security
The Global Market and Strategic Importance Heavy oil reserves are geographically concentrated, with Venezuela and Canada holding the largest documented deposits. These resources play a pivotal role in the energy security of consuming nations.
