Assessment of Yield Stress in Oil-Based Drilling Fluids
, 2023 Yield stress is commonly used to describe the rheological properties of drilling fluids. There are various methods to define such yield stress. Some approaches provide yield stress values sufficient to derive a proper fluid mechanical model while other approaches define the fluid properties as comparable matters. Here logarithmic values from shear rate

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs
Deep Underground Science and Engineering, EarlyView.A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Carbon emission assessment of tunnel infrastructures: From construction to operation
Deep Underground Science and Engineering, EarlyView.This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Deep Underground Science and Engineering, EarlyView.The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Well Control Problems Associated With Gas Solubility in Oil-Based Drilling Fluids.
, 1988 Gas contamination of an oil-based drilling fluid during drilling operations, whether it be by the flow of formation gas into the wellbore (gas kick) or by the drilling of gas-bearing formations (drilled-gas), poses a potential hazard to the drilling ...
