Fracking utilizes technology to solve energy problems by using a hydraulic fracturing method to fracture of rock and extract its power with a pressurized liquid
Many people on multiple sides of the fossil fuels issue are paying close attention to the concept of fracking today. This is an innovative approach to retrieving natural gas from layers of shale rock from deep within the earth.
Use of new technologies and equipment, such as the electrical sounding geophysical instrument at AGI, makes it possible to extract gas in areas of shale that are unreachable with traditional technologies and equipment. These new techniques and advanced equipment allow extensive fractures in shale to be made using man-made hydraulic processes.
Such things as three-dimensional imaging allow oil field technicians and scientists to select the places for drilling with unprecedented precision. Combining such techniques as horizontal and vertical drilling with the use of highly pressurized fluids achieves fracking by injection into selected spots in the shale field.
By opening up new fractures and channels in the rock, the captured natural gas is extracted at greatly increased rates. When a potential shale field is selected, the drilling process is started and can run for 30 to 60 days. The target area can be as much as a mile below the surface of the earth. When the desired location is reached, the new well is encased in concrete to provide protection to local groundwater. Once that is completed, water and other specialty fracking fluids are injected under pressure to create the hydraulic forces that fracture the shale and begin the process of extracting the natural gas that is freed up by the process.
