Light Hydrocarbon Geochemistry: Insight into Mississippian Crude Oil Sources from the Anadarko Basin, Oklahoma, USA

Salt Karst and Collapse Structures in the Anadarko Basin of Oklahoma and Texas

Introduction The current study summarizes years of investigations of salt karst and resultant collapse features in and around the Anadarko Basin of western Oklahoma and the Texas Panhandle. These investigations have involved integrated studies of: 1) the subsurface distribution and thickness of Permian salt beds; and 2) field studies to identify areas where outcropping strata are disrupted and ...

Characterization and Evaluation of Light Hydrocarbon in Northwestern Iranian Crude Oil by Detailed Hydrocarbon Analysis (D.H.A)Gas Chromatography

Lighthydrocarbons are commonly used to evaluatecrude oils to determine oil families in reservoirs undergone some kind of alteration process. In this study crude oil contentsfromNorthwestern IranDelta (samples A, B and C)were analyzed in order to evaluate the IranDelta petroleum system independent of higher molecular weight markers. Ultra high resolution gas chromatography was used in separation...

Geochemistry of the Mississippian Delle Phosphatic Event, Eastern Great Basin, U.s.a

The Middle Mississippian Delle phosphatic event marks a significant change in depositional conditions in the Devonian–Mississippian Antler foreland basin of North America. Stratigraphic and petrographic studies show that deposition of Delle-event rocks ended a long period of open-marine carbonate sedimentation when facies shifted to phosphorites, cherts, fine-grained siliciclastics, and lime mu...

Sources of the Volatility Puzzle in the Crude Oil Market

A remarkable feature of the crude oil market is a dramatic rise in oil price volatility over time which has been accompanied by a substantial fall in oil production volatility. We investigate the sources of this opposite evolution of both oil market variables. Our main …nding is that the observed volatility puzzle can be rationalized by the fact that the price elasticities of both oil supply an...
