Paper presented at the SPE Canada Unconventional Resources Conference, September 28–October 2, 2020
Paper Number: SPE-199978-MS
... Abstract Geomechanics plays a significant role in hydraulic fracture initiation and propagation and in the interaction between hydraulic fractures and natural fractures, especially in unconventional reservoirs. This paper provides a detailed description of a geomechanical characterization and...

Paper Number: SPE-199987-MS
... Abstract Reducing fracture/well spacing and increasing hydraulic fracture stimulation treatment size are popular strategies for increasing hydrocarbon recovery from multi-fractured horizontal wells (MFHWs). However, these strategies can also increase the chance of fracture interference, which...

... subjected to fracture generation and subsequent production. The fracture generation of the child wells was directly modelled in the reservoir simulator with hydraulic fracture conductivity as an exponential function of pressure. The conductivity-pressure relationship of the newly created hydraulic fractures...

... injection during the EOR period. The objective was to evaluate recovery by flooding the reservoir with the EOR agent from one hydraulic fracture and producing the reservoir fluid from the adjacent fractures in the same wellbore. Further development in completion design is required where alternate fractures...

Paper Number: SPE-200004-MS
... Hydraulic fracturing is an important method to improve the oil and gas production in low and ultra-low permeability reservoirs ( Zhao et al. 2016 , Kumar et al. 2017 ). Since its inception in 1947, a significant progress has been made in the fracturing technology and the materials employed...
