Weakly Consolidated Sandstone Petrology Characteristics and Geological Significance—Taiyuan Formation in Liujiang Basin

Petrology of the Massillon Sandstone at the Type Locality

Event Ordering Reasoning Ontology Applied to Petrology and Geological Modelling

The inference of temporal information from past event occurrences is relevant in several applications for geological domains. In such applications, the order in which events have happened is imprinted in the domain as visualspatial relations among its elements. The interpretation of the relative ordering in which events have occurred is essential for understanding the geological evolution in di...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Geological and Geochemical Features of Alborz Basin Coal Deposits, Iran

The Alborz coal basin is located in northern part of Iran. The coal deposits of Shahrood in eastern Alborz, Zirab in central Alborz and Abyek in western Alborz were studied as typical coalfields of the basin. Shemshak Formation which is the main coal-bearing sequence was formed during the Triassic-Jurassic in the basin. It consists of sandstone, siltstone, shale and claystone, which variedly al...
