The Secret of Pangaea: How this Ancient Continent Shapes the Future of the North Atlantic.
Hidden in the deep waters of the North Atlantic Ocean is an offshore sedimentary basin called the Jeanne d'Arc Basin. The formation of this basin is closely related to the breakup of the ancient supercontinent Pangaea, and has become an important part of the current geological structure and oil and gas resources of the North Atlantic. Over time, how this region shapes the future energy industry will become a focus of global exploration.
The Jenna-Duck Basin was formed as a result of spreading and collapse, a phenomenon that reflects the forces that broke apart ancient continents.
The formation process of the basin
The Jenna-Duck Basin is a vast area of shallow water off the east coast of Canada that is influenced by the tremendous forces of plate tectonic plates. In the late stage of the Pangaea supercontinent, the compression and deformation of the ancient Precambrian and Paleozoic strata formed the structural basis of the earth's crust. As the strata stretched multiple times, these ancient rocks experienced crack expansion and subsidence, eventually developing into the Jenna-Duck Basin we see today.
As the basin settled, it was gradually filled with sediments eroded from neighboring areas, forming a rich geological structure.
Geology and Oil and Gas Potential
For a basin to generate, capture and store fossil fuels, a combination of geological factors must be present. The salt rock layers and their complex stratigraphic structure in the Jenna-Dake Basin provide important support for the region's oil and gas potential. Especially during the Late Triassic and Early Jurassic periods, excessive salt deposits were deposited in the basin, further affecting subsequent structural deformation and the accumulation of oil and gas.
From the perspective of oil and gas generation and capture in the Jenna-Dake Basin, high-quality upper Jurassic source rocks are the key to successful exploration.
The history of oil exploration and development
The Canadian government first issued permits for oil and gas exploration in the Jenna-Dake Basin in the mid-1960s. The first exploration well, Murrr G-67, began drilling in 1971, and the discovery of Hibernia P-15 in 1979 marked the beginning of oil production in the area. As these discoveries were reported, the entire region known as "New Find and Labrador" experienced an economic boom.
As of 2022, five oil and gas producing areas have been discovered in and around the Jenna-Dake Basin, and new oil field development plans are underway.
Future Outlook
As the global demand for renewable energy increases, how the oil and gas resources in the Jenna-Dake Basin will affect the energy structure of North America and the world has undoubtedly provided researchers and energy experts with new ideas. . This sedimentary basin is not only a witness to ancient geographical changes, but also an important stage for future energy exploration.
How do we think about the impact of this ancient continent’s geological history on the distribution of petroleum resources today and in the future?
