Natural gas pressure of mining fissure

Because in the process of exploitation of natural gas, salt and sand attached in the water, leading to salty and muddy difficult to re-use. People often in the publicwastewater treatment plant worn surface treatment fracturing residual water, rather than through injection well underground recovery or disposal, is most common inthroughout the Northeast America Marcellus shale, and the origin of this point is also the fracturing of the debate.

In order to reduce the risk of fracture, and reduce the exploitation ceramic proppants of worry,Professor Reible points out that we must do two things: first, the drilling operationmust strictly implement best practices for the industry; second, must be coordinated,reused or re injection water in the more well, or improve surface treatment. Butresearchers at Cockrell School of engineering is committed to the innovation and the cooperation work.

Fracturing fluid cost and environmentally friendly use of natural gas

Natural gas used for hydraulic fracturing is said to be in American breakthrough, shale gas has low cost, but the domestic cost but has not closed, what reason be? A bossinadvertently say one of the mysteries of. Fracturing fluid is the main cost of shale gasis said to account for more than 70%, and the main component in the shale gas fluidssuch as sodium salicylate and quaternary ammonium salt, sodium salicylate salicylic acid if not made of raw materials or without high level such as pharmaceutical grade,the intermediate process of sodium salicylate as raw material for the production of salicylic acid in phenol water crude sodium salicylate the solution of sodium salicylate,take this cost can be greatly reduced by at least half or even below 40%, however at the cost of the crude sodium salicylate containing 2-3% phenol toxicity great. Thisleads to two problems, one is USA really with crude sodium salicylate as fracturing fluid (maybe it can oppose shale gas from USA environmentalists and proposed the pollution of fracturing fluid containing phenolic evidence), this can be from the exportstatistics or manufacturers such as the biggest foreign trade personnel than domestic manufacturers to understand, two is the 2-3% of phenol will be diluted to what extentas to whether the trace phenol also has the role of sterilization effect of 2-3% relative to the groundwater quality can be ignored or even play a positive role in the pollution of water resources, the domestic serious groundwater pollution serious situationdecision is difficult. So, the oil well fracking fluid cost can be greatly decreased by more than half, the key is to consider the influence of environmental protection.

Petroleum proppant (ceramic sand)

Grains of MaiDe Hydraulic Fracturing Proppants has a high temperature, high pressure, corrosion resistance, high strength, high conductivity, low density, low breakage rate and other characteristics, mainly for deep low-permeability reservoirs, currently the most widely used at home and abroad.
By species classification can be divided into: high sand proppant ---- no pressure consolidation strength, consolidation fast, good permeability, low density; fracturing proppant ---- Anti spit back a high pressure consolidation strength , crushing low permeability, low density; coated MaiDe lightweight proppant---- remarkable resilience and long-term use at temperatures below 232 ℃ formation; quartz sand proppant ---- acid low solubility for fracturing and acidizing support, a higher sphericity and conductivity.
Divided by the anti-crushing strength: 52Mpa (7500psi), 69Mpa (10000psi), 86Mpa (12500psi) three series.
Divided by the volume density: low density, medium density, high density.

Shale gas revolution "will affect the fracturing proppant

Recently the United States took the lead on the mining of new energy technology, Japanese media said it was "shale gas revolution", could you tell me the revolution in the field of energy will ceramic proppant the geopolitical? Beijing reader: comrade li jie li jie: hello! Shale gas is a kind of unconventional natural gas, a vast global shale gas resource distribution and huge reserves. The United States using high and new technology take the lead in a lot of exploitation of shale gas, opened the prelude of "shale gas revolution". The energy structure is undergoing major ceramic proppant manufacturers, increasing energy self-sufficiency. By the United States of the shale gas revolution is sweeping through more and more countries, the world's energy supply and demand will be significant changes in energy prices have a significant impact. Japanese finance Business Weekly said: "shale gas as a" rich energy reserves, is seen as air pollution and global warming star of hope. In tepco fukushima accident "go nuclear" calls, shale gas may be related to the natural energy complement each other, bring about a revolution to change the world energy structure. The U.S. energy information administration estimates that the United States has 860 trillion cubic feet of technically recoverable shale gas resources, including "proven reserves" is 273 trillion cubic feet.
