Closed-loop geothermal systems (CLGS) have been recently proposed as an alternative to
the conventional enhanced geothermal system (EGS) concept to address many of the issues …

Brief summary Multiple supervised and unsupervised artificial intelligence techniques have
been adapted and applied for real-time drilling monitoring and optimization purposes. This …

Deep closed-loop geothermal systems (DCLGS) are introduced as an alternative to
traditional enhanced geothermal systems (EGS) for green energy production that is globally …

Riser gas events appear during offshore drilling operations when there is a presence of gas
in a marine riser above the subsea BOP, which has been recognized as a hazardous …

The high solubility of the invaded gas in oil-based drilling fluids and the heat transfer
between annulus fluids and the surrounding formation make the accurate prediction and …

Two-phase flow modeling is important in well construction field for well planning and real-
time applications. In this paper, a new non-isothermal two-phase flow model is presented …

With ongoing development of oil exploration and techniques, there is a significant need for
improved well control strategies and formation pressure prediction methods. In this paper, a …

Abstract With Managed Pressure Drilling (MPD) becoming increasingly important to oil and
gas well construction, there has been a growing demand for comprehensive models that can …

Improper hole cleaning is a major cause of non-productive time (NPT) in drilling. Current
hole cleaning practices are mostly based on experience, rules of thumb and simplistic …

Non-aqueous drilling fluids (such as synthetic-based mud) are frequently used to drill one or
more sections of an oil/gas well to reduce drilling problems such as shale sloughing …
