Exploring Conventional and Unconventional Reservoirs in the Neuquen Basin - Module 12

Today's field trip is to the central sector of the Neuquen Basin.

The video discusses conventional reservoirs and the petrological system.

The sedimentation rate and the formation of channels in the Vaca Muerta shale are also mentioned.

📚 The video discusses the geological formations in a specific location.

⛰️ It highlights the transition from offshot shales to fluvial conglomerate deposits.

⚠️ The speaker challenges the traditional belief of oil migration and emphasizes the role of overpressure.

🔑 The video discusses the different formations in the Cuenca region, including the Vaca Muerta and Quituco formations.

💡 There is a correlation between the conglomerates found in the center of the Cuenca region and the Vaca Muerta formation.

🧩 The presence of a significant discontinuity called the intra-balanginian discontinuity is explored, which has led to the formation of the Bajada Colorada.

📚 During diagenesis, rocks can lose porosity, especially fine-grained sands.

💪 Coarse-grained rocks, like conglomerates, are more resistant to diagenesis and can limit the presence of fine-grained materials.

🌊 Conglomerates can act as good reservoirs due to their high permeability, even with poor grain selection.

🌀 In a turbidite reservoir with roof load, there are two peaks: conglomerates and turbidites.

🌊 The presence of clay minerals in the suspended load of a turbidite reservoir is critical for diagenesis.

🗻 The contact between lacustrine deposits and the Vaca Muerta formation is important in the Puerta Curaco area.

📚 Different levels of concretions can be observed in the sedimentation zones, indicating pauses in sedimentation and deeper sedimentation zones having more continuous concretions.

🔍 The behavior of a horizontal well when encountering concretions is discussed, highlighting the potential changes in gamma ray readings and the possibility of encountering fractures.

🌍 The formation of irregular limestone banks through the combination of isolated concretions is demonstrated, showcasing the varying topography in sedimentary environments.

The video is about an immersive virtual course on Campo.

The location is in the central sector, with a reservoir of sands and a Jurassic anticline structure.

The sands in the formation have deformities and normal faults, indicating accumulation by turbidity currents.
