The enhancement of the thermal performance of heat exchanging equipment transport
energy at low financial cost by various techniques is presented in this review. Various …

The paper presents an in-depth review of the liquid unloading by vortex tools in the low
production gas wells or hilly pipelines from the perspective of liquid unloading mechanism …

During the drilling activity, in an extended reach well, the deposition of cuttings (solids) in the
annulus can lead to issues such as differential sticking and inefficient hole cleaning. This …

The advent of deep-reading directional electromagnetic logging-while-drilling
measurements brings opportunities in imaging complex formations around the wellbore. In …

Multiphase flow simulations were run in OpenFOAM utilizing InterFoam, a volume of fluid
type solver. A concentric annulus geometry was constructed and periodic boundary …

The underbalanced aerated mud drilling is used more widely in unconventional oil and gas
exploitation to maintain bottom hole pressure below reservoir pressure. However, the three …

Blow-out prevention and formation gas/fluid influx control is a major concern in any drilling
operation. In conventional drilling, the only widely accepted response to a gas influx is to …

Casing Drilling is an innovative drilling method wherein the well is drilled and cased
simultaneously. The small annulus of Casing Drilling can create a controllable dynamic ECD …

Natural gas hydrate (NGH) is a kind of new type green energy source with giant reserves
which has been thought of highly by energy explorers in the world. However, NGH breaks …

Abstract Precise prediction of Equivalent Circulating Density (ECD) is one of the most
important challenges during drilling operations. This becomes more vital in deep-water …
