Overbalanced drilling is the most common drilling technique; nevertheless, it has several
disadvantages such as formation damage, mud losses, and stuck pipes; challenges that are …

Immense oil and gas reserves exist in the deepwater of the South China Sea, and the first
priority for implementing successful drilling and completion operations without reservoir …

Радиус проникновения фильтрата бурового раствора является одним из характерных
параметров загрязнения пласта. Проникновение фильтрата бурового раствора влияет …

Supercritical carbon dioxide (SC-CO 2) jets are of increasing interest in drilling and
completion engineering due to their superiority over water jets. To understand the nature of …

The paper presents a study on the restoration of permeability of the bottomhole formation
zone after intervasion of the filtrate of drilling flushing fluid. The author conducted a study on …

The wellbore multiphase flow and managed annulus pressure are key issues during drilling
in hydrate reservoirs. In this study, the intercoupling interactions of free gas, drilling fluid …

Drilling and completion processes can often result in reservoir contamination around the
wellbore, leading to decreased oil and gas productivity and significant economic losses for …

Supercharging in the vicinity of a borehole is an important factor that affects formation
damage and drilling safety, and the filter cake growth process has a significant impact on …

The drilling mud-filtrate invades into a reservoir is a dynamical process after a formation was
opened in oil exploration. Since the invasion profiles of formation resistivity vary with time …

When reservoirs are penetrated using water-base drilling fluids, the permeability of the
formation to oil is reduced by the permeability of the formation. Conducting experiments to …
