Hydraulic fracturing displayed their prowess accelerate gas development process

Hydraulic fracturing is a certain pressure to the liquid injected underground in the friable rock cracks open so that gas can be quickly discharged from shale in the process.

Before the start of the fracturing, engineers use 2D and 3D imaging techniques to determine the "best starting point." Geologists often will first drill a vertical hole 500 to  1500 m in order to determine the region's reserves of natural gas and ingredients. Computer modeling can more accurately predict the content of the  shale gas  exploration program and the best. In the actual mining process, once they reach the desired depth horizontal vertical wells will open up to the move to extract more natural gas to create the conditions. shale gas are generally stored in the 1000-3500 m, while the horizontal wells can be extended to 2 km away.

Fracturing horizontal wells will open in a lot of branch pipelines, this will interfere with the smallest possible activities on the ground while neighboring areas come into contact with the gas in more gas. Drilling is complete, the number of layers of metal pipe and cement laying the pipe sleeve to protect the upper strata four weeks and make completions. Subsequently, the fracturing fluid is injected with high pressure fracturing crevices. Gas flow path is established the need to maintain a stable flow environments.

This requires about 95% of the water to 0.5 to 2% and 4-5% of the fracturing fluid mixture into the fracture sand fracturing, this process is called "Support."   hydraulic fracturing   fluid carefully to ensure that the ratio of the flow of fracturing fluid, four weeks to prevent corrosion of metal pipes, to prevent microbial contamination of natural gas quality breeding. Rock crushing pressure will be generated after the gas pressure inside the well to the surface. Subsequently, the gas will be transported to the processing center, and pipeline transportation for consumer use.
