The M1 aquifer, found in the Berea Sandstone, is almost entirely confined to the eastern half of the Lower Peninsula. Porosity in the Berea Sandstone ranges as high as 20 percent with positive correlation between porosity and permeability. Permeability is high where the sandstone is not shaly. Limestones, dolomites, shales and shaly carbonate
A rock unit called Berea Sandstone is famous for three things. First, the small spaces between the sand grains can hold oil. The Berea was one of Ohio's first major oilproducing layers. By 1886, over 2,000 wells had been drilled into the Berea in eastern Ohio. Second, the Berea was perfect for making grindstones. During the 1870s, the Berea ...
01/12/1991 · • No significant difference in CFE or penetration was observed between tests in Berea Sandstone cores cut parallel and perpendicular to bedding. Behavior in rocks with greater permeability anisotropy still needs to be determined. • Flow does occur through loose debris left in .
The core holder, gas supply coil and transfer cells were placed inside a temperaturecontrolled hightemperature oven. Produced fluids were collected in a fraction collector. Berea sandstone cores, crude oil having API gravity and cP viscosity (at 3000 psi and 180 F) and 2% KCl brine were used in the experi ments.
