Paper Number: URTEC-3715179-MS
... includes Proppant Transport Efficiency (PTE) versus Perforation Flow Ratio (PFR) correlations based on the computational fluid dynamics/discrete element method analysis to describe the proppant distribution within each cluster. To the authors’ knowledge, this is the first application of a coupled simulator...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 20–22, 2022
Paper Number: URTEC-3720345-MS
... Abstract The plug and perf method of hydraulic fracturing stimulation divides and isolates wellbores into a series of stages, each stage consisting of multiple clusters of perforations. Uniform distribution of proppant across all clusters within a stage can decrease completion cost (i.e. lower...

... in 2021. The CiC refracturing method was to cement a 3.5-in. liner in the legacy 5.5-in. casing, where the original perforations were sealed, and new plugging and perforating (P-n-P) operations were performed in the reconstructed wellbore. During the BH refracturing, the treating pressure gradually...

Paper Number: URTEC-2021-5254-MS
.... Computational Fluid Dynamics (CFD) has been used to model proppant transport in wellbore to improve perforation and fracturing design for achieving uniform proppant placement. However, traditional CFD modeling of a full-scale stage is computationally expensive, which limits its applicability in the completion...
