... unconsolidated formations depleted reservoirs wellbore strengthening crosslinking Loss circulation is the root cause of many drilling problems that have challenged the oil and gas sector for many years. The loss of drilling fluid can jeopardize well control and increases tendency pipe sticking which...

...Jia Li; Zhengsong Qiu; Hanyi Zhong; Xin Zhao; Weian Huang The application of wellbore strengthening treatment has less effect on shale formations. Several numerical studies were developed to describe the mechanism, which promoted the development of wellbore strengthening theory. Previous studies...

... and for wellbore strengthening applications in permeable formations. API standard high-pressure-high-temperature (HPHT) filter press in conjunction with ceramic disks is used to quantify fluid loss reduction. Hydraulic fracturing experiments are carried out to measure fracturing and re-opening pressures...

... of this study is to investigate the hypothesis of wellbore hoop stress increase by fracture sealing. Anisotropic stress state has been used with assignment of individual criteria for fracture initiation and propagation. Our results demonstrate that fracture sealing in “wellbore strengthening” cannot increase...
