...Haiyan Zhu; Chuhao Huang; Xuanhe Tang; John David McLennan Summary Temporary plugging technology has been widely applied in multicluster fracturing for the uniform growth of multiple fractures. To investigate the propagation behavior of multiple fractures and explore a better fracturing scheme...

... the laminations have a considerable impact on the effectiveness of the shear slippage on the fracture height growth. Larger shear fracture toughness and smaller spacing of the bedding layers add more resistance to the fracture height propagation and require larger pressure to breakthrough. Additional results show...

...R. S. Seright; Dongmei Wang Summary Associated with the Milne Point polymer flood (on Alaska’s North Slope), this paper explores the unusual shape of hydrolyzed polyacrylamides (HPAM) breakout/propagation during dynamic polymer retention measurements in Milne Point core material. In contrast...

... more complex than the vertical and rectangular shape assumed by 2D models. The experimental studies on the role of height and inclination of natural fractures have revealed some other phenomena (e.g., bypassing process that the fluid-driven hydraulic fracture propagates up the back side of the natural...

... fractures during pumping, (ii) considerable additional upward fracture height growth (~300 ft) after well shut in, and (iii) very complex LF-DAS strain rate patterns for a small fiber-to-stage offset. Advanced geomechanical modeling was performed to simulate the hydraulic fracture propagation...

.... Fracture initiation and near-wellbore propagation from infill horizontal wells drilled with different azimuth from the optimal azimuth in the unstimulated area is poorly understood, largely because of the stress shadow (or induced stress) caused by MSFMP. In this study, we propose an integrated method...

... strength, which further indicates the necessity of the newly proposed TSL. Second, the initial tensile strength, controlling when the cohesive crack starts propagating, has the greatest effect on the hydraulic fracturing among all TSL shape parameters. The effects of TSL parameters become less significant...

... propagation were investigated. Furthermore, fracture propagation was investigated based on post-fracturing fine reconstruction, high-energy computed tomography (CT) scan, acoustic emission monitoring (AEM), and analysis of a fracturing pressure curve. Finally, suggestions on fracturing treatment were proposed...

..., indicating that when the infill well hydraulic fracture (HF) propagated close to the parent well stimulated region, only a main straight fracture was propagating. Also, the number of seismic events diminished abruptly, suggesting some barrier or an attenuation process for the MS. To clarify the mechanisms...

Each region was represented by a single‐porosity system. The DDA propagation...

...Guanqun Yu; Sebastien Vincent-Bonnieu; William R. Rossen Summary Since the 1980s, experimental and field studies have found an anomalously slow propagation of foam (Friedmann et al. 1991, 1994; Patzek 1996), a phenomenon that cannot be fully explained by surfactant adsorption. Friedmann et al...

In this study, our in‐house hydraulic fracturing simulator is used to simulate fracture propagation. The induced rock deformation and corresponding strain‐rate variations along offset...

The objective of this study is to develop a robust model that can capture the dissolution process and wormhole‐propagation phenomena that occur during CFA. This work develops a CFA model using computational‐fluid‐dynamics (CFD) techniques coupled...

Rossen Summary Foam reduces gas mobility and can help improve sweep efficiency in an enhanced‐oil‐recovery (EOR) process. For the latter, long‐distance foam propagation is crucial. In porous media, strong foam generation...
