Considerable lost circulation of oil-based drilling fluid often occurs because of pores and
fractures that develop in formations, which can significantly increase drilling costs. In this …

Over the past few decades, engineering failures have existed, and lack of knowledge, and
safety practices have led to various catastrophic events of blowouts causing countless …

The present work presents CFD-DEM results for filter cake formation under dynamic filtration
in a highly permeable heterogeneous porous medium conceived as a staggered array of …

The stability of the plugging zone has a great impact on lost circulation control and gas
invasion prevention in fractured reservoirs. In this work, the concept of “cavitation‐induced …

Due to the development of shale bedding and micro-fractures, it is very easy to induce
complex downhole accidents such as leakage during the drilling of horizontal Wells, and the …

During the drilling of an oil well, the phenomenon of drilling fluid esca** from the annular
region into the formation is known as lost circulation. Besides the financial and time losses …

Well drilling involves the circulation of drilling fluid, with a notably non-Newtonian behavior,
in contact with the porous boundary of the well-formation system. The presence of …
