Experimental Investigation of the Growth Law of Multi-Fracture during Temporary Plugging Fracturing within a Stage of Multi-Cluster in a Horizontal Well

Yanchao Li et al.

Summary: In this study, a true tri-axial hydraulic fracturing system was used to simulate temporary plugging fracturing in a horizontal well with multi-stages and multi-clusters. The results showed that using specific combinations of temporary plugging agents resulted in optimal fracture propagation geometry. Increasing the proportion of larger particle size temporary plugging agents improved the effectiveness of temporary plugging fracturing and tended to open new fractures. Higher temporary plugging agent concentration and cluster number led to more diverting fractures and increased overall complexity of fractures.

Field-Scale Experimental Study on the Perforation Erosion in Horizontal Wellbore under Real Fracturing Conditions

Baocheng Wu et al.

Summary: This study investigates the effect of various factors on perforation erosion during limited-entry fracturing in horizontal wells by developing a field-scale flow system. The experimental results show that there are two stages of perforation erosion, and the shape of the perforation changes after erosion. The study also finds that high injection flow rates, large proppant size, using ceramic proppant, and low viscosity fluid lead to more severe perforation erosion.

Numerical Simulation of Multifracture Growth under Extremely Limited Entry Fracturing of Horizontal Well

Tengfei Wang et al.

Summary: This study investigates the mechanism of multifracture growth and the design optimization of extremely limited entry (ELE) fracturing in multi-cluster horizontal wells. The results show that perforation friction in ELE fracturing can counteract the difference in fluid allocation caused by stress interference, resulting in even fluid allocation but significantly different fracture geometries. The in situ stress profile and 3D fracture stress interference determine the fracture geometry, and the in situ stress distribution within a perforated stage has a significant impact on the fluid allocation between different perforation clusters.
