An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

25 g of oil sands extracted by dynamic accelerated solvent extraction, yielding 177 mL of bitumen–toluene extract and clean dried solids in approximately 12 min. Abstract Determining the oil, water, and solids (OWS) contents of oil sand is essential to many aspects of the oil sands industry including mine planning, optimization of extraction processes,

ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...

This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.

ABSTRACT Conventional geochemical biomarkers include saturated, aromatic, and carboxylic acid compounds. Saturated and aromatic biomarkers, however, form the foundation of many geochemical studies because of their abundance and intrinsic significance.

Experimental methods in chemical engineering: Electrospinning
Abstract Electrospinning produces micro‐ and nanofibres by forcing a polymeric solution through a fine needle in an electric field that produces a filament that accumulates onto a collector plate. The fibre morphology depends on solution properties, distance between needle and plate, feed rate, and electric field intensity.
