The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman
Journal of Petroleum Geology, EarlyView.ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

The effect of karst system occurrence on flood peaks in small watersheds, southwest China
Hydrology Research, 2021 Flooding at small basins is characterized by weak predictability, sudden onset, and rapid disaster formation, especially in karst areas. Therefore, an accurate flood simulation will be helpful for flood control and disaster reduction.

REVIVING ABANDONED RESERVOIRS WITH HIGH-PRESSURE AIR INJECTION: APPLICATION IN A FRACTURED AND KARSTED DOLOMITE RESERVOIR [PDF]
, 2005 The field operator, Goldrus Producing Company, has been unable to secure funding needed to continue the field demonstration phase of the project. Accordingly, we have temporarily halted all project activities until necessary funding is obtained. Goldrus is confident that funds can be acquired by third quarter 2005 at which time it will be necessary to ...

Sedimentology, EarlyView.ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

3D geological modeling of mine karst geothermal reservoir and geothermal resources evaluation
Meitan xuebaoThe traditional geothermal reservoir volume method is suitable for the evaluation of geothermal resources in large-scale regions, but there is a significant error when it is used for the evaluation of mine geothermal resources.

Water and Environment Journal, EarlyView.Tracer testing assessed hydraulics and nitrate removal in three full‐scale agricultural drainage treatment wetlands over 3.5 years (three tests). The first test showed rapid, short‐circuited flow and low residence time. After modifying the collection system, the second test increased residence time from 1 to 7 days.

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Evaluating multiple competing biotic and abiotic processes and how they interact with carbon dioxide (CO2) in aquatic systems, is critical to understanding regional and global carbon cycles. Here, we used an aquatic continuum of the Bahe watershed, within a semi‐arid region, to establish a comprehensive conceptual framework for identifying CO2
