A complete workflow is presented covering: 1) utilization of reference logs, e.g., gamma ray, to correct image log depth using cross correlation and/or dynamic time warping, 2) automated identification of sidewall core cavity in borehole image log using the circle Hough transform, and 3...

... Abstract Previous experimental observations have shown the formation of distinct failure patterns and cavity shapes under different stress and flow conditions. With isotropic stress, spiral failure patterns with localized shear bands are likely to form. On the other hand, under anisotropic...

... Abstract Cavity completions have been widely used to increase productivity from non-conventional sources such as coalbed methane reservoirs and "heavy" oil from weakly consolidated formations. In the 1990s, the technique was applied to conventional wells where massive sand production...

... fractures, generally provide storage space as sinks or sources. Note that vugs and cavities directly connected with fractures (e.g., Figure 3 ) are considered part of the fracture continuum. More specifically, we conceptualize the fractured-vug-matrix system as consisting of (1) "large" fractures...

... Localized tensile type post-failure stabilization During step flow tests, a sudden increase in sand rate followed by a low level of sand rate is observed. Loose sand particles without load bearing exist around irregular perforation cavities and these particles are swept away when the flow rate...

... confining cell. The parameters changed in these experiments were the ratio of grain size to cavity diameter, grain distribution, cavity diameter, oil-water ratio, confining stress and directional stress. A similar experiment was previously conducted by the Colorado School of Minesand IKU, however, the tests...

... The conventional picture of a perforation is of a carrot-shaped cavity surrounded by a region variously described as the "crushed zone" or "damaged zone", containing material weakened by the impact of the shaped charge and characterized by crushed sand grains. The cavity may be at least partly...

The failure analysis of the model is based on the pitting corrosion. A method and revised criteria have been proposed to predict the threshold pressure for a derated tubing...

It predicted the onset of shear failure and the subsequent strain softening initiated from the cavity face and propagated inside the medium. Strain softening proved to be the main mechanism for material...
