Aiming to address the difficulties in predicting the collapse strength of sand control screen
pipes with internal corrosion defects under the external pressure in offshore unconsolidated …

Underbalanced perforation can substantially reduce formation damage and improve the
efficiency of production operation. The field in question is a giant oil field in Southwest Iran …

Jet perforating is an important way to improve oil and gas recovery. The metal jet formed by
the traditional perforating method will cause serious damage to the casing, reduce the life of …

The study of oil and gas flow patterns after perforation completion is essential for well
productivity prediction and solutions optimization. Due to the multi-scale flow characteristics …

During oil-well production, there are often cracks, breaks, and perforation corrosion on the
screen pipe that can significantly deteriorate sand control and pipe strength. To repair …

Screen pipes collapse failure occurs frequently under formation confining pressure, which
seriously affects the oil and gas production. However, the unified equation for calculating …

Grey cast iron, prized for its durability and thermal performance in applications like engine
cylinder liners, sees widespread use in defence, engineering, and transportation …

Preventing screen blockage due to sand poses a significant challenge. The article combines
computational fluid dynamics (CFD) and discrete element method (DEM) to establish a fully …
