Drowning of the Upper Marble Falls carbonate platform (Pennsylvanian), central Texas: A case of conflicting “signals?”

Porosity estimation in the Fort Worth Basin constrained by 3D seismic attributes integrated in a sequential Bayesian simulation framework

“…The Barnett Shale has comparable I P values with the Bend, but shows different I S . Erlich and Coleman (2005) observe that MF is characterized by lateral variations in thickness and present differences in geologic facies between the upper and the lower parts. Log measurements in Figure 1b exhibit the distinct characters of the geologic units between its upper and lower sections.…”

Geologic framework for the national assessment of carbon dioxide storage resources: Permian and Palo Duro Basins and Bend Arch-Fort Worth Basin: Chapter K in <i>Geologic framework for the national assessment of carbon dioxide storage resources</i>

“…The boundary of the Bend and Comyn SAU is defined by the 3,000-ft reservoir-top depth taken from over 20,000 well penetrations (IHS Energy Group, 2010; Nehring Associates, Inc., 2010) and from regional cross sections (Lahti and Huber, 1982;Erlich and Coleman, 2005), the Muenster arch and associated fault system, the Ouachita front and associated fault systems, and the lateral extent of the Smithwick-Pregnant shale seal where it is at least 50 ft thick, as determined using formation-tops differencing from 194 wells (IHS Energy Group, 2010). The rocks within the SAU deepen eastward, toward the Ouachita front, and thicken to the north and west where the Caddo limestone is included within the reservoir rocks of the SAU.…”

Integrated Synthesis of the Permian Basin: Data and Models for Recovering Existing and Undiscovered Oil Resources from the Largest Oil-Bearing Basin in the U.S.

“…Group as defined by Manger and Sutherland (1984), , and Erlich and Coleman (2005), which is wholly Morrowan in age. Figure 35 illustrates the lithostratigraphic relationships of the Morrowan-age units discussed in the Erlich and Coleman (2005) The lower Marble Falls carbonate unit is characterized by several different facies types and associated depositional environments.…”

“…36). Two depositional models have been proposed, first by Kier (1980) and secondly by Namy (1980) and Erlich and Coleman (2005), and will be discussed in that order.…”

“…Namy (1980) and Erlich and Coleman (2005) contended that the Lower Marble Falls member (in the same area as Kier [1980]) was deposited on a southeast-facing distally steepening ramp. In this competing model, a thick (coalesced and stacked to ~120 ft [37 m]) algal bank complex forms at the shelf margin and rapidly grades to heavily bioturbated and eventually laminated spiculitic biomicrites seaward (Namy, 1980).…”
