• Cover: The cover figure illustrates a digital model of the Carson Basin, offshore Newfoundland (eastern Canada) and shows a significant moment in the basin's geological history: the reservoir rock (in yellow: sandstones of the Jeanne d'Arc Formation) has been deposited on top of the source rock (brown: shales of the Egret Member). Legend: red - basement; orange - sand/siltstone; green - salt; purple - dolomite; grey - shale; blue - limestone. The orange tip of the grey compass points north. Black crosses are well locations: B: Bonnition H-32; O: Osprey H-84; S: Skua E-41; G: St. George J-55. See the related paper by Wielens et al

• Cover: Diagrams illustrate a two-stage model of fault-block filling with petroleum migration across a fault. Stage 1: a petroleum column builds up in carrier sands near the fault zone, and oil is injected into the fault and moves upwards due to buoyancy forces. Petroleum migrates into the first hydrostatic reservoir encountered (i.e. the deepest reservoir strata) until equilibrium is established between the oil in the fault zone and that in the reservoir. Quartz cementation may partly seal the fault zone during progressive burial. Stage 2: continued burial results in source rock maturation and renewed oil expulsion, and another oil charge builds up in the migration avenue. As in stage 1, this oil moves upwards in the fault zone until it meets a hydrostatic reservoir unit -- in this case, a shallower unit than in stage 1. The result is that the reservoir fills from the bottom up, with individual reservoir units containing petroleum of varying maturity, GOR and API. See the related paper by Karlsen and Skeie
