Muddy sandstone
Tengah Facies: Muddy marine sandstone with occasional grit beds and conglomerate. The member is usually deeply weathered but appears not to have been strongly lithified at any stage. St. John Facies: Flysch-like marine muddy fine sandstone with minor laminae of carbonaceous matter. Usually moderately well lithified.This allowed a coral reef to build on top of the mud. A more geological time passed and the environment of the area changed again, the deposits of sand, mud, and carbonate sediment were buried and lithified into the sequence of sedimentary formations which, from bottom to top, are sandstone, shale, and limestone.Muddy Sandstone Modifications: Areal extent Revised AAPG geologic province: Denver basin Publication: MacKenzie, D.B., 1965, Depositional environments …

Muddy sandstone, Powder River Basin: rejuvenation of an old play with horizontal drilling By Stephen A. Sonnenberg 1 View Affiliations Source: First Break , Volume 38, Issue 5 , May 2020, p. 83 - 89 DOI: https://doi.org/10.3997/1365-2397.fb2020038 Published online: 01 May 2020 Previous Article T able o f C ontents Next Article AbstractShale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated.1134.

Although operators did produce from conventional wells in Cretaceous reservoirs such as the Muddy Sandstone (western equivalent of the Newcastle Sandstone), Frontier Formation, and the Carlile Shale, historically less-productive Cretaceous-age unconventional reservoirs are now the main focus of exploration and production in the Powder River Basin.Muddy/Newcastle Sandstone (Lower Cretaceous) incised - valley fill reservoir.

It is overlain by thick unit of mudstones and asymmetrical ripple marked fine-grained …Feb 1, 2023 · A muddy sandstone is developed farther downflow of this initial matrix-poor sandstone. Continued particle settling results in the upward displacement of interstitial fluid and suspended fine-grained sediment and subsequently a low-density mud transforms the flow into a two-part suspension that deposits a bipartite bed. Shale and the Muddy Sandstone are considered underex-plored and to have potentially significant potential. Looking at these two plays in concert, the contrasts between the conventional and unconventional opportunities . are clear.
