Rehabilitation of Sandstone Wells

Diagenesis of Luxembourg Sandstone

Research has been conducted into the diagenesis of the Luxembourg Sandstone. Literature studies were followed by a visit to the outcrop, after which thin sections were studied. The Luxembourg Sandstone Formation has been deposited in the Hettangian and Sinemurian, both lower Jurassic ages. A sea strait connecting the Northern German Basin and the Paris Basin was located in present day Luxembour...

Anisotropy of sandstone permeability

Small-scale probe permeability measurements on differently oriented faces of highly compacted and quartz-cemented Viking Formation sandstones yield detailed permeability distributions that appear to be diagnostic of the grainand lamina-scale fabric of the samples. Permeability anisotropy of a single ‘structureless'-appearing sample is low, reflected by a kV / kH-ratio of 0.7; corresponding k-di...

Bituminous Sandstone Mixtures

In certain sections of the state of Indiana sources of recognized ag­ gregates for use in bituminous construction are very few, and the trans­ portation of aggregates to the job site from remote locations becomes necessary. Often the distance over which the aggregate must be moved is considerable, and the importation involves the expenditure of a size­ able sum of money, which it would be desir...

Quantitative Characterization of Permeability Fluctuations in Sandstone

Sedimentary rocks have complicated permeability fluctuations arising from the geological processes that formed them. These permeability fluctuations significantly affect the flow of fluids through the rocks. We analyze data on two sandstone samples from different geological environments, and find that the permeability fluctuations display long-range power-law correlations characterized by an ex...
