Paper presented at the SPE Low Perm Symposium, May 5–6, 2016
Paper Number: SPE-180268-MS
... Abstract Heterogeneous rocks with broad pore size distributions, such as carbonates and clay-rich sandstones, often display widely varying behavior. The interaction of micro- and macro-porosity in these complex rocks makes them difficult both to understand and to characterize. Pore scale...

... (for example, clay content), salinity, pH, Eh, microemulsion viscosity, crude oil, co-solvent and other variables. Some static adsorption and kinetic adsorption studies have been reported on sandstone, limestone, and permeable carbonate reservoirs, but few on ultra-lower permeable rocks, such as the Bakken...

Measured porosities in both the shales and siltstones are typically 4.5 to 7.5% with low matrix permeabilities ranging from about 80 to 700 nanodarcies. Lying between the sandstones of the Frontier and Blair, the Baxter...

Paper Number: SPE-107950-MS
...Abstract Abstract In tight gas sandstone the productivity of a well is sometimes quite different from that of a nearby well. Several mechanisms for this observation have been advanced. Of interest in this paper is the possibility that a small change in water saturation can change the gas phase...
