Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 17–19, 2024
Paper Number: URTEC-4032879-MS
... Abstract The scope of this paper is to introduce a non-invasive simplified workflow that estimates perforation efficiency utilizing raw stimulation data. The paper illustrates how results from this simplified workflow were accurately and successfully benchmarked against industry-known...

... placement (higher SDE) is beneficial for well productivity. The results of proppant allocation using two data types, fiber optic distributed acoustic sensing (DAS) and images of perforation erosion, are presented, and compared in this case study from Vaca Muerta field.

... to bullhead diverter treatments that re-stimulate existing perforations and these are no longer a "best practice" in most cases (Barba 2024). Once mechanical isolation is employed and legacy perforations are sealed off permanently the treatment becomes a "recompletion" of previously unstimulated portions...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 17–19, 2024
Paper Number: URTEC-4055303-MS
.... For the ultrasonic scans, a casing-wall loss percentage threshold was employed as the primary plug performance metric. When testing alternative plug options, static plug pressure tests were conducted at the surface prior to perforation. Drillout times were also assessed. Results/Observations/Conclusions...

Paper Number: URTEC-3854538-MS
... Abstract Limited entry technique is often employed to achieve uniform flow distribution between perforation clusters during hydraulic fracturing treatment. However, the proppant distribution between clusters will not necessarily be uniform, even if the slurry distribution is uniform...

... 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...

... of both primary and infill wells, resulting in a loss of resources. This loss can be lessened by completion strategies that minimize the impact of the fracture-driven interactions. The best well performance was obtained using engineered, rather than geometric, perforation placement; and by pumping lower...

Paper Number: URTEC-3723896-MS
... Abstract Video camera-based perforation analytics in hydraulic fracturing provides the highest resolution fracture diagnostics. It directly provides the condition of perforations which are the main "touchpoints" to the reservoir for proppant placement and eventually production. Without...

... 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...
