Some fractures are far longer than others, while their fracture widths close to the wellbore are far smaller. Due to the stress shadows arising from the fracture interactions, some wellbore zones...

One frequent and global cause of stuck pipes is the inefficient removal of formation cuttings from the wellbore while drilling, which is the focus of the developed real-time model. Poor hole cleaning is also a major contributor to other...

..., 2009 ; Dimakopoulos et. al., 2013 ). Abstract Drilling fluid is a yield stress fluid, which can trap invading gas in the wellbore. The entrapment of gas leads to the decrease of ECD and the inaccuracy of wellbore pressure calculation during gas kick. This study established a mathematic model...

... Abstract Solid particles (sand) production in oil and gas wells can significantly affect well productivity. The negative effect can be caused by sanding up of the perforations, tubing and downhole equipment, and abrasive wear of the well completion and surface equipment. The near-wellbore zone...
