An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

Deep Underground Science and Engineering, EarlyView.
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

Earthquake environmental effects and ESI 2007 of the 6th February 2023 Kahramanmaraş earthquakes along the East Anatolian Fault Zone (Türkiye)

Quaternary International
The February 6, 2023 Kahramanmaraş earthquake doublet resulted in a range of devasting impacts on the built and natural environments. Here the macroseimic intensity of the event is assessed using the Environmental Seismic Intensity Scale (ESI 2007), which considers a range of primary and secondary earthquake environmental effects (EEEs) resulting from ...

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 ...
