Deep-water pebbly sandstones and conglomerates - Fagies and reservoir characteristics

The deep-water massive sandstone facies includes thick sandstones with individual beds normally thicker than 50 cm. Shaly partings between beds are normally absent, in contrast to the classical turbidite facies where shaly partings are ubiquitous. Beds commonly lack primary sedimentary structures. Pebbly sandstones also lack shaly partings between beds, but are coarser, better graded, and commonly contain parallel lamination or …
