Immersive Virtual Course on Field - Module 11

📚 The video discusses the concept of conformity and conformity discontinuities in stratigraphy.

🌊 There is a discussion on the rapid change in relative sea level and its impact on sedimentation.

🏞️ The video explores the formation of deltas and the occurrence of catastrophic flooding in the study area.

📚 The video discusses the geological formations in the Neuquén Basin, including the presence of cross-stratified dunes and continental deposits.

🌊 It explains how the Mediterranean Sea desiccation theory, proposed by a famous Chinese scientist, explains the formation of the Neuquén Basin as a satellite basin isolated from the open sea.

⛰️ The video highlights the presence of eolian deposits in the basin, which were possibly located about 200 meters below sea level.

🌊 The video discusses a catastrophic flooding event in the Cuenca region, causing a rapid rise in sea level and connecting it to the ocean.

⛰️ Instead of the expected deposition patterns, the flooded area contains fluvial and aeolian deposits with large dunes and offshore deposits above them.

🏞️ The video mentions the presence of a transgressive surface and its significance in the geological formation of the area.

📚 The video discusses the formation of dunes and sediment layers in the Neuquén Basin.

💧 The formation of reservoirs is explained through the percolation of water and the resulting salt deposits.

🌋 Vulcanism and the presence of islet bridges contribute to low permeability and the transformation of volcanic glass.

🔍 The upper part of the Agrio population has a sequence limit where lower Troncoso sandstones appear.

🌍 The Troncoso upper sandstones are 14-16 meters thick on the surface, but can reach up to 60 meters underground.

💎 The Troncoso superior sandstones have various minerals, including siltstone, potassium chloride, and gypsum.

⛽️ The Troncoso inferior sandstones are the best conventional reservoirs in the Neuquen Basin, particularly in the Pastor, Chiguido, and Lomitas areas.

⚓️ The Troncoso superior sandstones act as an effective seal for the reservoirs, making them highly productive.

⭐ The presence of a highly effective seal called Ferri Creta in the base of the Neuquén group prevents the formation of reservoirs in the Malargüe area.

🔍 There is a discordance between the Rayoso formation and the Neuquén group, and the second Rayoso formation overlaps the second Eva-political formation.

📚 There is a distinct diagenesis in the Neuquén group, and above it is a level of conglomerate cemented by iron.

Module 11 focuses on a unique and rare level with a particular foundation.

The level acts as a seal for the group above and is always above an important level with various soils.

There is a significant contact between the Ralloso formation and the Neuquén group, creating an entrapped oil reservoir.
