Paper presented at the International Petroleum Technology Conference, March 23–April 1, 2021
Paper Number: IPTC-21318-MS
... Abstract Hydraulic fracturing is a widespread well stimulation treatment in the oil and gas industry. It is particularly prevalent in shale gas fields, where virtually all production can be attributed to the practice of fracturing. It is also used in the context of tight oil and gas reservoirs...
