... of Lower Paleozoic platform margin. The upward-shallowing platform sequence consists of shallow subtidal ribbon-laminated carbonates (Patterson Member) overlain by shoal water to tidal flat massive dolomites and fenestral cryptalgal carbonates (Austinville and Ivanhoe Members) that pass up into red...

... Abstract The Ivanhoe, Rob Roy and Hamish Fields lie in the Moray Firth of the UKCS in Block 15/21 and contain undersaturated oil trapped in the prolific Upper Jurassic Piper reservoir in tilted fault block traps. The fields were brought on stream in 1989 and since then the reservoir model has...

... of the KSZ, dykes exhibiting clouded feldspar and high-alumina amphiboles occur on the upthrown side of the Budd Lake fault zone, which has a trend similar to that of the Ivanhoe Lake fault. Therefore a second thrust block may exist, raising the possibility that the KSZ represents the basal member...

... to the Renee manifold and then onwards through a 21 km-long pipeline to the Amerada Hess-operated AH001 FPF in the nearby Ivanhoe–Rob Roy fields to the north ( Fig. 6 ). The Cromarty Sandstone Member was excluded from the development plan due to thin oil and gas columns ( Fig. 5a ) which resulted in water...

... beneath the Rattray Volcanics Member. There is no positive evidence on the available seismic data supporting the interpretation of a central volcano associated with the Ivanhoe magnetic anomaly. The presence of hyaloclastite indicates that the area was at times subaqueous, with lava building out...
