This study numerically investigates counter-current slug flow by considering the motion of a
Taylor bubble in annular conduits with downward-flowing liquids using the Volume-of-Fluid …

Reducing energy consumption during drilling operations is beneficial to both the
environment and economy. Frictional drag reducers (FDR) are widely used to reduce the …

Early detection and characterization of anomalous events during drilling operations are
critical to avoid costly downtime and prevent hazardous events, such as a stuck pipe or a …

The main goal of cementing is to provide reliable zonal isolation throughout the life of a well.
The integral of cement protects the casing and prevents fluid formation from migration. This …

Plunger lift is effective for dealing with liquid accumulation in gas wells. With the
development of digital plunger control systems and large databases, machine learning has …

Eccentricity of the casing frequently exists in actual drilling process. This is one of the main
reasons responsible for poor mud and cement displacement. In such cases, zonal isolation …

Led by new developments of horizontal drilling and hydraulic fracturing techniques, organic
rich shales have been contributing significantly to a gas production in the US. In drilling …

Automatic prediction of drilling incidents can be conducted through either a purely data-
driven approach or a hybrid approach. In the first approach, the variable space is typically …

Predicting and optimizing the rate of penetration (ROP) is a crucial part of drilling
optimization. While numerous machine learningbased ROP prediction methods exist, their …

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