Formed millions of years ago, slate and shale rocks have served as important materials throughout human history. Metamorphic rocks are rocks that have changed from one type of rock to another. For shale gas, hydraulic fracturing of a reservoir is the preferred stimulation method (see graphic below). Best Answers The bottom line is that in a conventional reservoir, the gas is in interconnected pore spaces, much like a kitchen sponge, that allow easier flow to a well; but in an unconventional reservoir, like shale, the reservoir must be mechanically “stimulated” to create additional permeability and free the gas for collection. Quick Answer: What Should I Do After Pest Control? They typically form in environments where muds, silts, and other sediments were deposited by gentle transporting currents and became compacted, as, for example, the deep-ocean floor, basins of shallow seas, river floodplains, and playas. This makes slate useful for making roof tiles because it can be split into separate flat sheets. unlike mudstone, shale Shale is a sedimentary rock. Slate is formed by a metamorphosis of clay, shale and volcanic ash that results to a fine-grained foliated rock, resulting in unique slate textures.
