The downhole high-temperature problem has become a bottleneck that restricts the efficient
development of deep shale gas resources in China. This study highlights the characteristics …

Downhole tools are at risk of high-temperature failure during drilling operations in deep and
ultra-deep wells. To solve this problem, researchers have developed temperature models for …

Downhole heat damage during drilling seriously restricts the exploration and development
of deep oil and gas reservoirs and geothermal resources. The petroleum industry focuses on …

During the drilling process, the downhole high-temperature problem has considerably
limited the exploration and development of deep oil and gas reservoirs and geothermal …

In this paper, a transient model that describes the heat transfer processes in the wellbore
during circulation is presented. A simulation of the transient effect on these heat transfer …

This paper presents the development and application of a numerical model to predict the
temperature distribution of the vertical borehole system during circulation and shut-in …

Accurate prediction of the wellbore temperature is critical to achieve pressure control in
controlled gradient drilling. In accordance with the mass, momentum, and energy …

High bottomhole temperature can lead to decreased downhole tool life in geothermal and
high-pressure/high-temperature (HPHT) oil and gas wells. The temperature increase is …

In the ocean environment, the riserless mud recovery (RMR) system uses the return line as
the return channel, resulting in the injection and return channels for the drilling fluid …

Both analytical and numerical modeling methods have helped explore power generation by
producing steam with the binary organic Rankine cycle or ORC. A steady-state fluid …
