... evaluation method of shale reservoirs considering shale fracability-mobility-lithology is established. The weight of these physical parameters in sweet spot is determined by the entropy weight method. Kriging interpolation algorithm is applied to discretize the sweet spot distribution along the wellbore...

... of hydraulic fractures in a horizontal well is more complicated than for natural fractures, however the following items can be evaluated: perforation effectiveness, near wellbore connectivity and far field fracture growth. The production logging can provide downhole flow profile in a quantitative way and yield...

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

As the EF matures with more infill development, the number of frac hit events is set to grow given the increased well density and large completion...

...). Foundation Energy Management (FEM) employed a series of technologies to increase their understanding of the reservoir and its hazards. These technologies include geochemical liquids analysis from wellbore cuttings via Rock Volatiles Stratigraphy (RVStrat), passive acoustic imaging sensors (known as Measuring...

... 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...

.... 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...
