Preliminary Evaluation of Silica Sand in Sudan with Respect to Fracture Sand [PDF]

Journal of Petroleum & Environmental Biotechnology, 2016
Hydraulic fracturing is a well stimulation method performed on reservoirs with low permeability to improve the flow of hydrocarbon into wellbore. Certain chemicals are injected into the well under very high pressure; propping agent, such as sand is added to the fracturing fluid to keep the fracture open. Silica sand was appeared as ideal proppant agent
