The Cretaceous period is a major division of the geologic timescale, lasting from about 145 to 66 million years ago. It’s the last period of the Mesozoic Era, following the Jurassic and preceding the Paleogene of the Cenozoic Era. Key characteristics of the Cretaceous period include:

1. Diverse Dinosaur Fauna:
This period is well-known for its diverse dinosaur species, including famous ones like Tyrannosaurus rex, Triceratops, and Velociraptor. It’s characterized by the dominance of dinosaurs on land.

2. Development of Flowering Plants:
The Cretaceous saw the first appearance and rapid evolution of flowering plants, which significantly altered landscapes and ecosystems.

3. Marine Life:
The Cretaceous oceans were populated by a diverse range of creatures, including mosasaurs, plesiosaurs, and numerous species of fish and invertebrates.

4. Climate:
The climate during the Cretaceous period was generally warmer than today. There was no polar ice, and sea levels were higher, creating shallow seaways that extended deep into continents.

5. Mass Extinction Event:
The Cretaceous period ended with one of the most significant mass extinction events in Earth’s history, known as the Cretaceous-Paleogene (K-Pg) extinction event. This event led to the extinction of the dinosaurs (except for their descendants, the birds) and many other species.

6. Geological Changes:
The period saw significant geological changes, including the breakup of the supercontinent Pangea and the opening of the Atlantic Ocean.

In the Middle East, the Cretaceous period has also played a significant role in the region’s oil geology. The Middle East Basin, the world’s richest oil and gas province, features several Cretaceous structures and reservoirs. The Upper Cretaceous period, in particular, is noted for its significant oil reservoirs, like the Mishrif and equivalent formations like the Natih and Shuaiba in Oman. The region’s subsurface geology indicates the presence of extensive deltaic sands and overlying carbonates in the Middle Cretaceous isopach-facies, which are major oil producers in countries like Saudi Arabia, Kuwait, Oman and Iraq.

These findings highlight the significant impact of geological events from the Cretaceous period on modern oil and gas exploration and production.

At Cretaceous Energy, our focus is on the detailed reconstruction of tectonic plate movements, encompassing periods before and after the Cretaceous era. We are committed to the belief that a thorough understanding of these ancient geological shifts holds the key to uncovering new, untapped energy resources. By delving into the history of plate tectonics, we aim to reveal energy potentials that have remained hidden until now.
