Fatigue acid fracturing: A method to stimulate highly deviated and horizontal wells in limestone formation

Kunpeng Zhang et al.

Summary: This study focuses on the application of fatigue acid fracturing technique in limestone formation, finding that fatigue acid fracturing effectively reduces fracture pressure and weakens stress shadow effect. Factors such as inclination degree, weathering zones, and calcite blocks have noticeable impacts on fracture morphology and propagation.

Mechanism study on steering acid fracture initiation and propagation under different engineering geological conditions

Bing Hou et al.

Summary: The study found that steering acid fracturing in carbonate reservoirs is influenced by natural vugs, and high pumping rates may cause changes in fracture direction. Acid etching creates multiple channels with high conductivity rather than etching the entire fracture surface.

Integration of discrete fracture reconstruction and dual porosity/dual permeability models for gas production analysis in a deformable fractured shale reservoir

Qixing Zhang et al.

Summary: This study established a model to compare the effects of different desorption mechanisms on shale gas production and evaluated and optimized fracturing operations and well completions using microseismic hydraulic fracture mapping technology. The results showed that the DPDP model was more accurate than other classical models, and the variation range for hydraulic fractures could reach nearly 5%.

Features of fracture height propagation in cross-layer fracturing of shale oil reservoirs

Wang Yizhao et al.

Summary: The study showed that hydraulic fractures in different sandstone and shale layers exhibit various propagation patterns, including cross-pattern, straight-line, and ladder-shaped fractures. Hydraulic fractures in shale layers are restricted by bedding structures, resulting in smaller height compared to fractures in sandstone layers.
