Assessment of Wellbore Integrity of Offshore Drilling in Well Testing and Production

Investigation into the dynamic characteristics of downhole perforation tools with multiple shock absorbers

“…His model ignored the effects of shock absorber quality. In 2016, Gao Deli et al [18][19][20] proposed mechanical models from no buckling to plane buckling, and plane buckling to helical buckling. Li et al [21] expounded upon the future direction of research on string mechanics in oil and gas wells and corresponding research methods, indicating directions for future research.…”

Numerical simulation of the thermomechanical behavior of cement sheath in wells subjected to steam injection

“…Several approaches have been proposed to study the stress field in wellbores and their structural integrity under downhole conditions, either based on analytical formulations (eg. Thiercelin et al, 1998;Li et al, 2010;Bui and Tutuncu, 2013;Wang et al, 2016;Zhang et al, 2015;Liu et al, 2017;Zhang and Wang, 2017), or numerical simulation (eg. Ravi et al, 2002;Shahri et al, 2005;Gray et al 2007;Ferla et al, 2009;Fleckenstein et al, 2001;Shen and Beck, 2012;Bai et al, 2015;Guo et al, 2015).…”
