...Bin Wang; Jun Li; Binggui Xu; Tao Jia; Hui Zhang Perforation plays an important role in the fracture morphology near the wellbore and the propagation of hydraulic fracturing fractures. Therefore, it is of great significance to find out the fracture morphology and propagation law during perforation...

...Naoto Araki; Nobuo Morita Summary Oil and gas reservoirs are normally completed as either openhole or perforated wells. Although a perforated well has hundreds of perforations, a single perforation is normally used for perforation interaction analysis, assuming the perforations are shot...

... during temporary plugging fracturing, a 2D finite element method (FEM)-discrete fracture network (DFN) model is established. An improved traction-separation law is used to describe the constitutive behavior of fractures under different types of stress. The model is further integrated with the perforation...

...David Cramer; Matt White; Cody Douglas Summary Studies have shown that achieving a consistent perforation hole size in casing (i.e., entry hole) and zero-phase perforation gun orientation led to improved treatment distribution among multiple perforation clusters in plug-and-perf limited entry...

... of an underperforming interval through plug and abandonment (P&A) and perforation of a new interval are traditionally completed with a combination of wireline (WL) and tubing conveyance. An alternative method using enhanced coiled tubing (CT) is presented here; it enables a rigless and efficient workflow...

... are investigated. An artificial neural network (ANN) model is developed to predict proppant distribution in a cluster. The results identify that proppant distribution among perforations is generally toe-biased in a horizontal wellbore due to a high pumping rate. Proppants with large inertia easily miss the heel...
