Natural gas hydrates (NGH) are prone to causing pipeline blockage in flow assurance,
attracting considerable attention in the petroleum industry. This work reviews the significant …

As offshore oil and gas accumulate in deep water environments, the formation of gas
hydrates in water-based drilling mud has become a critical safety problem in drilling …

The hydrate reformation in marine gas hydrate production system can significantly affect the
accuracy control of the production pressure differential and even cause pipeline blockage …

The three–phase gas–liquid–solid flow, caused by hydrate decomposition in cuttings is a
main concern during drilling through gas–hydrate reservoir. In this study, a transient gas …

Recently, the technologies for the global modeling of the process of oil well drilling have
become widespread. Mathematical modeling is used in well design, virtual testing of various …

Natural gas hydrate (NGH) holds great promise as a source of clean energy. It is critical for
acquiring the largest possible in situ NGH core for NGH eigen features and resource …

Gas hydrates are an important sort of strategic energy resource in China because of their
enormous reserves and small contamination compared to traditional fossil fuels. Many …

Wellbore temperature field equations are established with considerations of the enthalpy
changes of the natural gas during the deep-water gas well testing. A prediction method for …

In the development of deepwater crude oil, gas, and gas hydrates, hydrate formation during
drilling operations becomes a crucial problem for flow assurance and wellbore pressure …

Transient-state gas and oil-based mud (OBM) two-phase flow in wellbore annuli will occur
during gas kick. The phase behavior of influx gas and OBM will make the gas kick during …
