...-dipping thrust slices. However, on the southern margins of Jabal Akhdar, Saih Hatat, and other domes ( Fig. 2 ), the Hawasina units form south-dipping thrust slices ( Fig. 2 ). Major valleys typically occupy the contact between the Hajar supergroup and the Hawasina nappes, because of the many, easily...

... of this formation are shallow water sediments, commonly glauconitic and laminated, whereas the partly quartz-cemented sandstones in the upper part of the type section ( Fig. 3 ) were deposited in a braided river system ( Fig. 5 ) and display wide variations in grain size, sorting and thickness, but no marked cyclic...

... associated with local deformation along the Maradi fault zone (locally known as the Haushi-Nafun fault, Enclosure 2a) in Middle to Upper Gharif times, possibly associated with the rifting of Gondwana. Consequently, it is preferred not to place the Middle and Upper Gharif in the Akhdar Group (cf. Angiolini...

... (e.g. Maradi Fault Zone) and within carbonate floaters of the infra-Cambrian Ara Salt. The substantial difference between the minimum and maximum stresses appears sufficient to bring optimally oriented faults close to incipient shear failure (i.e. frictional equilibrium). The results have been applied...

.... The application of a residual depth correction removes the depth error at the wells. Wells located in zones of inversion (e.g. Maradi fault zone, salt diapirs) are excluded from this depth conversion scheme as they show an anomalous velocity behaviour. Geostatistical modelling demonstrates that the expected depth...

... of the Early/Middle Cambrian Nimr Group and the Amin Formation. Pulses of sediment loading manifested by alluvial fan and braided river deposits from the west are the main trigger and driving mechanism for halokinesis. Results from the analogue modeling show that mini-basin formation can be caused...

.... This reservoir represents a complex series of heavily bioturbated shallow marine sandstones and nested valley fill channels. The Upper Burgan reservoir is targeted to increase its current production by more than five times, culminating with a plateau rate of 120,000 bopd. The dramatic increase in production...
