shale gas

Glossary of shale gas in mined from shale gas. Mainly adsorption (about 50%) or free (about 50%) state exists in the mudstone, carbon mudstone, shale and silty rocks sandwich, a very small amount to dissolve the state is stored in kerogen, bitumen and petroleum . Shale both

Natural gas generating source rocks, but also the accumulation and preservation of natural gas reservoir and cap rock. Exploitation of  shale gas  development has a long life and long production cycle advantages. But shale gas reservoirs with generally showed low porosity and low permeability material characteristics, resistance to airflow than conventional natural gas, all operations

Wells are required to implement the reservoir fracturing mined.
If this is not enough shale gas Glossary apt words, the following glossary of shale gas will be more vivid. Because shale gas "hide" a few kilometers underground rock formations, to mining requires drilling to several kilometers underground, the storage laminated  shale gas  shale cracked, allowing Chu

Which together shale gas deposit eventually collected and transported to the surface.
Natural gas and conventional gas fields in different shale gas in the shale and not long-range mass flow, if only vertical dig a well into the ground, there will be only a small amount of gas near the well overflow mined shale gas will very limited. To large-scale mining, needs to play a lot of wells

While the need to fight horizontal wells - vertical hit several kilometers, to raise horizontal boring, ensure that more gas can bring together.
Glossary third shale gas compared: shale gas and natural gas is now widely used as the main component is methane. Many of them are millions or billions of years ago, after the death of paleontological organic matter, through a complex physical and chemical processes after the formation. The difference is, the conventional

Scale natural gas reserves in the gas field. The places shale gas adsorption or free state, there is a few kilometers underground in the shale.
Shale is a fine particle size less than 0.0039 mm debris, clay, organic matter, etc., with a sheet-like or sheet-like bedding, easy fragmentation of a class of sedimentary rock. Because shale gas particularity, China has as distinguished from coal, oil and natural gas independent minerals.
Through these three shale gas terminology, and I believe that shale gas is concerned, we are no longer strangers on shale gas. In  unconventional gas  mining process, need to use the  Unconventional gas filler - Ceramic proppant.
