... Abstract Clay minerals are commonly observed in the Neogene succession of North Kuwait, both in the two viscous oil rich sandstone reservoirs (S1, S2) and intervening shale layers. SEM and XRD analysis of the core samples explain that Smectite is the dominant and Palygorskite, Illite...

... progradations and retrogradations deposited a stratigraphic succession defined by five facies-associations (i.e., shoal, tidal flat, tidal channel, lagoon, sabkha). Five lithofacies (i.e., shale, shaly sandstone, sandstone, carbonate-cemented sandstone, evaporite) were identified from core, elemental...

... Abstract Cyclic steam stimulation (CSS) and steamflood performances are strongly influenced by shaly barriers and cemented baffles in the heavy oil reservoir. Marine shales do act as a permanent barrier in most conditions, while non-marine shales and diagenetically altered cemented siltstone...

... Abstract The primary challenge in drilling shallow depth viscous oil formation in Kuwait is to achieve gauged holes while drilling in unconsolidated friable sand-shale alteration. Gauged holes are the key for the production techniques used in this field, where cement channeling and perforation...
