Enhanced Oil Recovery Techniques

Bu çalışmada, kireçtaşı ve dolomit türü karbonat kayaçların renk uzayı bileşenleri (RGB: Kırmızı, Yeşil, Mavi; HSV: Ton, Doygunluk, Parlaklık) ile tek eksenli basınç dayanımı (UCS) arasındaki ilişkiler incelenmiştir. Bu kapsamda, açık ocak işletmelerinden temin edilen kayaç örnekleri, önce dayanım testleri için blok ö…

This study investigated the effect of re-refined engine oil bottoms (REOB) on the morphological, chemical, physical and rheological performance of 50/70 penetration-grade bitumen modified with 5% ethylene–vinyl acetate (EVA). REOB was utilized specifically as a balancing agent to mitigate the excessive stiffness and w…

Hot mix asphalt (HMA) performance is significantly influenced by the chemical variability of bitumen, which is closely linked to crude oil origin. These source-dependent variations also affect the response of bitumen to polymer modification. This study investigates the mechanical performance of asphalt mixtures produc…

As the number of new wells is continuously increasing across oil fields to maintain and enhance hydrocarbon production, there is an ever-growing challenge to safely drill near existing wellbores, given their downhole location inaccuracy caused by well surveys with an ellipse of uncertainties up to hundreds of feet. An…

Viscosity reducers are essential additives for water-based drilling fluids (WBDFs), serving to counteract the rheological degradation induced by the high-temperature and high-salinity conditions commonly encountered in deep and ultra-deep well drilling. This paper systematically reviews the research progress in this f…

The western region of the Tarim Basin is a typical deep and ultra-deep oil and gas reservoir with complex geological conditions in China. This area includes a thick salt–gypsum layer, high-pressure brine layers, and other formations with high pressures and a complex pressure system. These geological features present c…

ABSTRACT The fluvial‐dominated deltaic to shallow marine depositional systems were studied by utilizing integrated approach of organic and inorganic geochemistry and petroleum system modeling (PSM). Employing an integrated approach encompassing through scanning electron microscopy (SEM), x‐ray diffraction analysis (XR…
