An experimental investigation of single Taylor bubbles rising in stagnant and downward
flowing non-Newtonian fluids was carried out in an 80 ft long inclined pipe (4°, 15°, 30°, 45° …

The exploration and extraction of hydrocarbons from subsurface reservoirs rely heavily on
effective wellbore drift flow management. This research delves into the economic and …

Poor hole cleaning is a major concern in coiled-tubing drilling (CTD), and it is often
associated with long nonproductive time that contributes significantly to the operational cost …

Riser gas events during offshore drilling operations are hazardous and challenging to
control. Therefore, knowledge of the gas influx sizes and distributions in a marine drilling …

To improve the pay zone exposure and avoid hazardous interbed, the wellbore trajectory is
necessary to be adjusted in real-time according to the geosteering data in a long horizontal …

This paper presents an innovative study that optimizes drilling operations by integrating
advanced camera systems and computer vision image processing techniques. The core …

The backreaming operation plays a significant role in safe drilling for horizontal wellbores,
while it may cause severe stuck pipe accidents. To lower the risk of the stuck pipe in …

Drilling a series of sinuous wellbore trajectories has emerged as a promising operation,
offering significant advantages in enhancing reservoir contact. Based on various …

Horizontal wells have been frequently used in many oil reservoirs, which has significant
advantages in improving oil development efficiency. During horizontal well drilling, the …
