“…The analysis of saturates, aromatics, resins, and asphaltenes (SARA) was achieved combining solvent microdeasphalting plus thin-layer chromatography of the deasphalted sample, as reported before. 32 One Iatroscan model MK-6 chromatograph was used for the hydrocarbon group-type analysis of the maltene fractions. For upgraded products, Asphaltenes were precipitated from the cracked heavy bottoms, their amounts then corrected by the abundance of the light end (about <250 °C, ∼ nC14−) to calculate their amount for the whole product.…”

“…Bitüm içerisindeki bu bileşenlerin oransal değişimi, bitümün hem reolojik hem de fiziksel özeliklerine belirgin bir şekilde etki etmektedir [7,11,13,33]. Her bir bitüm türü sadece temin edildiği kaynağa bağlı olarak değil, üretim işlemlerine bağlı olarak da bir birlerine göre farklı S-A-R-A içeriği ve buna bağlı olarak fiziksel ve reolojik özelikler sergilemektedir [5,[34][35][36]. İşte bitümün yapısındaki bu farklılıklar polimer ile bitüm arasında uyumluluk problemlerinin oluşmasına eden olabilmektedir.…”

“…With plastic creep characteristics and strong cohesion [1][2][3][4] , bitumen deteriorates the properties of the drilling uid and increases the risk of drill pipe sticking. 5,6 This could reduce the rate of penetration (ROP) and extend the non-productive time (NPT), causing signicant economic losses. Fig.…”

“…A saturate, aromatic, resin, and asphaltene (SARA) analysis has shown that the bitumen formed mainly includes saturates, aromatics, resins, and asphaltenes. [5][6][7] Different subfractions have shown different density and viscoelasticity. 5,8,9 Early studies 10 have found that increasing the content of asphaltene can increase the viscosity of bitumen.…”
