Where is shale formed
The Marcellus Shale is a geologic formation of shale rock buried deep under parts of Pennsylvania, New York and West Virginia. This formation contains a large amount of natural gas distributed throughout the shale in cracks and pores.claystone, hardened clay.Some geologists further restrict the term to a sedimentary rock that is composed primarily of clay-sized particles (less than 1 / 256 millimetre in diameter) and is not laminated or easily split into thin layers; such rocks that show cleavage roughly parallel to the bedding plane often are classed as clay shales. Claystones that are …The US and Canada are the only countries where shale gas is a significant part of the gas supply.

It’s six million years old or less.”. Geologist Mel Erskine. Photo: Sarah Phelan.This vertical variability is associated with the diversity of the processes and conditions that are involved in shale rock formation. At the rock formation stage, organic matter content is controled on three processes: production, destruction and dispersion. The intensity of particular processes vary depending on the place of deposition.TAKORDI SHALE Next to the Takoradi Sandstone is the Takoradi Shale. The two formation possess a common characteristic and is obvious they belong to the same depositional phase. The Takoradi Shale is located at Poasi, Tanokrom, Effia Nkwanta and Essipong.

In summary, the fluid flow in shale formation is controlled both by the pore size and by the properties of pore walls (surfaces). Due to the larger Vt, V2, V3, and smaller surface areas, as well as the high carbonate and illite content, the shales from Es 4 upper possess better production potential (Figures 10D,E). Significances and Prospects The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.
