... Abstract Precipitation of mineral scale in wellbores is a major concern in unconventional shale plays. Mineral scaling can negatively impact well performance, requiring costly well-intervention techniques for scale removal and production downtime. It is crucial to understand types of mineral...

Subsequently, a 3D model of the wellbore and reservoir is assembled to evaluate the distribution of pressure, temperature, and fluid velocity across the annular space, formation matrix, and fractures. drilling operation geology fracture complex reservoir log...

... transient analysis with DTS thermal modelling were combined to provide the production allocations along the wellbore. Cluster efficiency and uniformity for individual stages were computed and assessed from the results. The production allocations along the wellbore show clear variability between individual...

While the lateral lengths of each wellbore vary slightly from well to well, they are all essentially 2-mile laterals. sedimentary rock...

.... As the average slurry velocity reduces from one cluster to another, this leads to proppant settling and higher particle concentration in the lower portion of the wellbore. Also, the slurry makes a sharp turn to enter a perforation and the higher proppant density causes some particles to miss the perforation...

... 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...

... Abstract Liquid loading refers to undesirable accumulation of liquids (oil and water) in the wellbore. This typically occurs in late-life wells as the reservoir pressure declines. However, in unconventional reservoirs, liquid loading is also found to occur in fairly productive oil wells upon...

The wellbore pressure and acoustic emission (AE) activities of each cycle were concurrently measured to monitor...
