“…This is attributed to the competitive adsorption between the resins and the asphaltene molecules. Asphaltene molecules, as reported earlier, have a dipole moment over the range of 3.3-6.9 D [36]. This signifies the ability of asphaltene molecules to carry a greater charge than resins.…”

Traditional wettability measurement practices, introduced as early as the late 1950s, are still perceived as reliable industrial methods for characterizing wettability. These techniques, in contrast to the contact angle method, provide indices that can quantitatively describe the degree of wetting state. Nevertheless, these approaches can determine the current state of wettability, subject to limitations. By employing the zeta potential measurements technique, a complete wettability profile is derived. In this chapter, the theory behind this technique is discussed. A case study is presented where the wettability of limestone rock is investigated, as crude oil and asphaltenic solutions of varying concentration are added to the limestonewater suspension. Findings of this study are discussed with the possible mechanism in effect when wettability alteration is observed.

“…Two chemicals were selected for benchmarking and comparison purposes: Dodecylbenzene sulfonic acid (DBSA), which has been extensively reported in specialized literature as synthetic Asph dispersant [12,[16][17][18][19][20], and a commercially available Asph stabilizer (CPA) based on polyisobutylene.…”

“…As a result, DBSA is able to reduce the size of asphaltene aggregates to sub-micron scale [8,13], or even nanoscale [14], enhance the precipitation onset [6], and decrease the amounts precipitated [5,15]. However, it is unclear how the interactions between DBSA and asphaltenes affect the structure of asphaltenes.…”
