Klappentext North America, South America and China have large volumes of low permeability oil and gas resources. When combined with enhanced oil recovery techniques such as water injection, low permeability (tight) oil reservoirs have emerged as a viable new source of oil. The challenge for production and reservoir engineers is to specify injection water quality, rates and pressures to achieve optimum production levels.
