Factors influencing porosity and permeability, Wilcox Group (Eocene), Karnes County, Texas
Petrographic and petrophysical data from 57 sandstone samples collected from the available parts of a 2500 ft section of core (-5094 ft to -7474 ft) recovered from the Seaboard Oil Kolodziejcyk #1 well in southeastern Karnes County were used to determine the diagenetic changes within the rocks and …

Diagenesis And Controls On Porosity And Permeability In The Upper San Andres Formation Of West Texas
… petroleum production. The Upper Permian-aged San Andres Formation, composed primarily of dolomite and limestone, is a prolific reservoir. This study assesses diagenetic influences on porosity and permeability within the San Andres Formation along the northern CBP. Two cores from the Monument 4-2 …

The relationship of Permian San Andres facies to the distribution of porosity and permeability in the ODC field, Gaines County, Texas.
The ODC field, operated by Fina Oil and Chemical Company of Texas, is located in Gaines County, Texas on the northwestern shelf of the Midland basin. Consisting of 53 wells, the ODC field produces from 800 net acres involved in a water-flood injection program initiated in 1969. The primary …

Deposition and Diagenesis of the Blossom Sand, Panola County, Texas
<p>The Late Cretaceous Blossom Sand within the Austin Group is a historic gas reservoir in the East Texas basin, located at depths of approximately 2,000 ft below the surface. Since the discovery of the Carthage Field in 1918 in the East Texas Basin, the Blossom Sand has produced approximately 26 …

Comparison and correlation of lithostratigraphic and hydrostratigraphic units of southwest area 20, Pahute Mesa, Nevada test site
… places emphasis on the composition and lithic characteristic of the unit rather than the material properties of the rock that affect potential ground-water flow. Hydrostratigraphic units represent an improved method of defining potential ground-water flow by identifying and grouping …

Depositional environments and sandstone diagenesis in the Tyler Formation (Pennsylvanian), southwestern North Dakota
… North Dakota may be divided into upper and lower units, reflecting both a change in lithology and depositional environments. The lower unit is dominated by varicolored, noncalcareous shales and mudstones, siltstones, thin coal beds, and medium-grained sandstones. The upper unit in the …

Modeling of Real Gas Flow Behavior in Porous Media
… to the highly nonlinear variation of gas density and viscosity with respect to pressure, no analytical solution to the real gas diffusivity equation has ever been presented in the literature. Analytical solutions used in gas well testing and pressure analysis are based on idealized assumptions, …

Characterizing ash and substrate properties in sintered metal fiber diesel particulate filters using an advanced diagnostic approach
… (DPF) is one of these aftertreatment devices, and it is used to capture hazardous particulate matter (PM) from the engine exhaust stream. Over the lifetime of the DPF, incombustible materials like ash are deposited within the DPF. The presence of ash inhibits the exhaust flow and thus causes …

Thin and Etched Section Analysis of a Limestone in the White River Formation
… from the top of Sentinel Butte. Thin sections and etched sections were prepared from this sample and studied microscopically. The sample was found to be a dense, highly siliceous limestone which exhibits very thin, rippled laminations, ranging from one tenth to one half millimeter in thickness. …

Predicting Flow in Firebrand Pile using Pore Network Model
Firebrand pile ignition of adjacent materials requires an in-depth understanding of heat transfer and flow profile within the firebrand pile. Modeling the firebrand pile as a fibrous porous medium, this study identified a porosity-permeability correlation that accurately describes the transport …
