“…Basin evolution records of the Caney Formation of the Ardmore Basin show depositional environments of coastal and shallow marine origins (Fritz et al 2012) that greatly favored the formation and preservation of diatoms, thus biogenic silica content. The trends observed in silica concentration during rock-uid interactions also show signatures of high content of biogenic silica.…”

This study explores the geochemical causes of permeability loss in hydraulically fractured reservoirs. The experiments involved the reaction of powdered-rock samples with produced brines in batch reactor system at temperature of 95oC and atmospheric pressure for 7-days and 30-days respectively. Results show changes in mineralogy and chemistry of rock and fluid samples respectively, therefore confirming chemical reactions between the two during the experimental period. The shift in mineralogy of the rock included decreases of pyrite, feldspar, and carbonate content whiles illite content showed an initial increase before decreasing. Results from analyses of post-reaction fluids generally corroborate the results obtained for mineralogical analyses. In essence, the results reveal a complex trend of reactions between rock and fluid samples which is summarized as follows. Breakdown and oxidation of pyrite by oxygenated fluid causes transient and localized acidity which triggers the dissolution of feldspar, carbonates, and other minerals susceptible to dissolution under acidic conditions. The dissolution of minerals releases high concentrations of ions which subsequently precipitate secondary minerals. On the field scale, the formation of secondary minerals in the pores and flow paths of hydrocarbons significantly reduces the permeability of the reservoir, which culminates in rapid productivity decline. This study provides an understanding of the geochemical rock-fluid reactions that impact long term permeability of shale reservoirs. Findings from the study also reveal the potential of depleted hydraulically fractured shale reservoirs as carbon storage units.

“…In the Llano Uplift, central Texas, upper Cambrian shallow marine sediments unconformably overlie ca 1.4 to 1.0 Ga metamorphic and granitic Grenville rocks (Walker, 1992; Mosher, 1998; Mosher et al ., 2008). In the study area, north and west of the Llano Uplift, more than 900 m of Cambrian–Early Ordovician siliciclastic and carbonate sediments, divisible into the Moore Hollow and Ellenburger groups (Cloud et al ., 1945; Crowley & Hendricks, 1945; Bridge et al ., 1947; Cloud & Barnes, 1948; Ross, 1976; Barnes & Bell, 1977; Ruppel & Kerans, 1987; Kerans, 1990; Loucks, 2003; Morgan, 2012; Miller et al ., 2012), continue north and north‐eastward into the mainly peritidal Arbuckle Group (Donovan & Ragland, 1986; Fritz et al ., 2012) of Oklahoma. The Cambrian–Ordovician boundary is located in the uppermost part of the Moore Hollow Group (Barnes & Bell, 1977; Miller et al ., 2012) (Figs 1 and 2).…”

Microbial carbonates formed stromatolitic, thrombolitic, dendrolitic and maceriate (mazelike) fabrics in shallow marine Cambrian-Early Ordovician carbonates encircling Laurentia. However, poor preservation often hinders recognition of their specific components. Well-preserved examples of normal shallow marine limestones in the ca 490 Ma upper Cambrian Point Peak Member, Wilberns Formation, central Texas, include stromatolitic cones, steep-sided laminated rimmed columns with grainy interiors, and laminated and maceriate domes. Together these form decimetre to metre-thick biostromes. In these examples, a single component, microstromatolite, on its own or with minor calcimicrobes, creates macroscopic stromatolitic, dendrolitic, thrombolitic and maceriate fabrics. Microstromatolites constructed upward widening stromatolitic cones that developed into columns with laminated rims surrounding slightly depressed interiors. These columns accumulated allochthonous sediment by a 'bucket effect'. Their interiors contain either clusters of dendrolitic microstromatolite or ragged columns of laminated stromatolite-sponge biolithite, and are often characterized by a 'mottled' fabric that superficially resembles thrombolite. This mottling was formed by localized dolomitization around millimetric burrows that otherwise do not appear to have significantly influenced the biolithite fabric. Calcimicrobes, including cyanobacteria (Razumovskia) and microproblematica (Renalcis and Tarthinia), impart a mesoscopic clotted appearance to maceriate fabric, and locally to column rims, both of which are dominated by microstromatolite. Similar component-fabric relationships should be recognizable in rimmed columns and domes that were locally abundant elsewhere in Cambrian-Early Ordovician shallow carbonate seas.

“…Rifting ceased by middle Cambrian time and was followed by slow thermal subsidence that led to the formation of a shallow SE‐trending basin known as the Southern Oklahoma Trough (Feinstein, 1981). Alternating carbonates and shales were deposited from middle Cambrian to Middle Mississippian that reflect eustatic fluctuations in a carbonate shelf environment (Amati & Westrop, 2006; Eriksson et al., 2005; Feinstein, 1981; Fritz et al., 2012; Huffman, 1959; Jones Jr, 1961; McCaskill Jr, 1998; Pearson & Miller, 2014; Perry, 1989; Rottmann, 2000). These rocks form part of the Great American Carbonate Bank (GACB) that was present in the Southern Oklahoma Trough and extended along the whole eastern margin of the Laurentian paleo‐continent (Fritz et al., 2012).…”

Late Paleozoic Evolution of the Anadarko Basin: Implications for Laurentian Tectonics and the Assembly of Pangea

The assembly of supercontinent Pangea was completed by middle Permian with the closure of the Rheic Ocean along the Appalachian-Ouachita-Marathon belt on the eastern and southeastern margin (current directions are used throughout this paper) of the Laurentian continent (Figures 1a and 1b;Hatcher et al., 2010;Scotese, 1984). Diachronous collision occurred in the southern Alleghanian orogen during early Carboniferous, in the Ouachita fold and thrust belt during Late Mississippian to Pennsylvanian and terminated in the Marathon fold and thrust belt during Late Pennsylvanian to Cisuralian (formerly Early Permian) time (Hale-Erlich & Coleman, 1993;Thomas et al., 2004;Viele and Thomas, 1989). Late Paleozoic compressional belts are present on all sides of the southern Laurentian continent (e.g., Alleghanian, Antler, Ouachita-Marathon, and Sonoran belts in Figure 1c), as are widespread intraplate basement uplifts (e.g., Ancestral Rocky Mountains, Figure 1c).Numerous models for transfer of compressional stress from Laurentian margins to the plate interior have been proposed. Previous workers have attributed intraplate deformation of southeastern Laurentia to continental collision with Gondwana and peri-Gondwanan terranes (Dickerson, 2003;Graham et al., 1975); the effects of diachronous collision along the irregular southeastern Laurentian margin (Dickinson & Lawton, 2003;Kluth & Coney, 1981); flat-slab subduction along the Sonora margin (Ye et al., 1996); reactivation of pre-existing structures by collision along the Ouachita-Marathon and Antler orogenic belts (Marshak et al., 2003); and combined compressional forces from the Ouachita-Marathon, Sonora, and Antler orogenic belts (Leary et al., 2017;Sweet et al., 2021). Consensus has not emerged about what drove late Paleozoic Laurentian tectonics, in large part because of poor exposure of late Paleozoic faults in southeastern Laurentia.During Carboniferous time, a complex fault system developed along lithospheric weaknesses inherited from Mesoproterozoic weaknesses of the
