Not all mining water will disappear forever. hsp proppant In the process of drilling and hydraulic fracturing, we have one tenth to three-quarters of the water will flow back to the surface, and these reflux water contains toxic chemicals. Mining companies can use these water recycling, for the next hydraulic fracturing, or it can be stored in water tanks, also can be discharged directly into surface waters. Thus, if water is not properly treated back, it could contaminate local groundwater, further increasing the risk of the local water supply.
WRI said that China is not the only country affected by distress, large reserves of shale oil and gas resources, many of which are located in areas of water scarcity. Unfortunately, China is one of the countries most severely affected by distress.
In China, the South is more abundant water petroleum proppant resources, but most of the shale oil and gas resources in the north. China shale gas reserves are mainly concentrated in the Sichuan Basin and Tarim Basin, two regional water supplies are very tight, oil and gas extraction faces enormous challenges. Worse, large reserves of shale oil and gas resources are all densely populated areas, which means that if companies want to mine, in addition to diverted irrigation water, but also water and industrial competitiveness and domestic water. If not handled properly, shale oil and gas resources will lead to water shortages and water pollution double disaster of.
