Gas influx from reservoir into the wellbore during drilling, tripping, or other operations, is a
hazard. In the early stages, the influx may be nearly undetectable, but the kick can rapidly …

Abstract Knowledge of wellbore multiphase flow characteristics is important for early gas
invasion identification and treatment, especially in oil-based drilling fluid. The wellbore …

In this paper, we present a computational fluid dynamics (CFD) model to perform single-and
two-phase fluid flow simulation on two-and three-dimensional perforated porous media with …

As oil and gas exploration gradually advances into deep waters, the combined effects of
various types of gas kick and the accurate calculation of the gas-kick volume have gained …

Under shut-in conditions in deepwater drilling, the gas invading the bottomhole ascends
along the wellbore and accumulates at the wellhead, forming a high-pressure trap …

Brief summary Extended reach wellbores have distinctive behaviors in relation to gas kicks
compared to vertical wellbores requiring different well-control responses. Gas kicks behave …

Well control is an essential part of any drilling operation. Improper well control procedure
may result in blowout, and blowouts must be controlled to ensure a smooth drilling …

Gas kick is an undesirable problem in the drilling process, which can potentially lead to a
blowout. The primary intent of this study is to highlight gas migration and its effect on gas …

Bullheading, a technique often employed in well control operations, involves the forced
injection of fluids to displace unwanted gases or fluids downwards within a wellbore. The …
