... 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...

The assessment quantified the impact...

.... 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...

... thickness and show a good correlation to production performance. It was observed that the distribution of the perforated intervals in the completion stages corresponded to the most fragile rock types that would guarantee the propagation of fractures and an efficient connection with zones of interest...

... 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...

... Abstract Measurements such as in-well and cross-well fiber optics, perforation-imaging, and slant well coring have indicated that fracs from perforation clusters grow unevenly in the near wellbore and far-field. Sub-optimal cluster efficiency is caused by in-situ rock variations, poor cement...

... by increasing trends in instantaneous shut-in pressure (ISIP). Rate per perforation was found to be a statistically significant predictor of near wellbore connectivity. Far-field diverter was also used to enhance nearfield connectivity and achieve better uniformity. Introduction Hydraulic fracturing...

... Abstract To meet production targets and report fewer operational issues, many companies are looking to improve cluster efficiency during hydraulic fracturing operations by having more productive perforating clusters that contribute to well production. One key factor that has been emphasized...

... 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...

... 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...

The best well performance was obtained using engineered, rather than geometric, perforation placement; and by pumping lower...

... 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...

.... 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...
