“…nov. bacteria were able to reduce the pour point of crude oil by up to 24 • C and reduce the crude oil viscosity by up to 70% [66,72]. Recently, polyamine amide from canola oil showed potential as an excellent pour point reducer with small concentration [106]. Akinyemi et al (2018) also reported that Jatropha seeds and castor seed oil were able to reduce the pour point (from 24 • C to 8 • C) and the viscosity of waxy crude oils when a low dosage was used (0.1-0.3 vol %) [18].…”

When crude oil is extracted out of a subterranean reservoir at high temperature and pressure, it is usually transported via a pipeline, where the crude oil experiences radical changes in its physical and chemical properties, instigating numerous complications. Among the various flow assurance problems, wax deposition and build up are among the most commonly found. However, the accurate mechanism of wax deposition is still unclear and is widely debated among researchers. The mechanism under multiphase conditions is also an ambiguity. This review covers the six wax deposition mechanisms, the challenges in multiphase flow conditions, the latest types of chemical inhibitor, and a summary of factors governing chemical inhibitor performance.

Waxy crude oil has become a crucial unconventional oil alternative owing to the depleting conventional oil resources. However, ascertaining flow assurance in a waxy crude oil pipeline at low temperatures is challenging due to the high viscosity and gelation properties of waxy crude oil and wax deposition on the pipeline wall. Researchers and industries use different classes of chemical additives to resolve the flow assurance issues. The current review aims to build a relationship between the structural properties of chemical additives and their flow improvement efficacy. A wide array of compounds reported in the past decade has been critically examined to understand the progress in the field. Polymers form a bulk of these compounds. However, there is a shift toward polymer nanocomposites owing to their better effect compared to pure polymers. Surfactants, organic solvents, and other molecules have also been utilized as additives to ensure flow during waxy crude oil transportation. The presence of different structural properties such as alkyl chain length, aromatic rings, size of aromatic rings, polar groups, and others have been related to their effect on the flowability of waxy crude oil. Moreover, the factors related to scaling of lab-scale results to industry level have been enumerated. The future directions and perspectives related to utilizing structure–efficacy relationships of chemical additives have been discussed. In contrast to the existing literature, special importance has been given to the chemical structures of additives and their molecular interactions with waxy oils. The perspective of the structure–efficacy relationship will help in designing novel additives with greater efficacy and suitability for waxy crude oil.

“…Taking into account the status quo of sustainable development, the problem of heavy oil viscosity and difficult flow must be solved, and environmental protection requirements must be considered. Many researchers have made good progress in selecting non-polluting chemical raw materials and producing products that are green to the environment or that are within the environmental tolerance range [20][21][22][23]. Chen et al used waste glass to synthesize polymethacrylate and polymethacrylamide which have been used in heavy oil mining [24,25].…”

The low flow characteristics of heavy oil have brought many challenges to its exploitation. Looking for a cost-effective crude oil flow improver to reduce the viscosity of heavy oil is currently the most important challenge. Small-molecule crude oil flow improvers meet the above requirements and become an ideal target for oilfield heavy oil production. In this article, three kinds of barium salts of alkylbenzene sulfonates with different lengths of alkyl chains were synthesized from alkylbenzene sulfonic acid and barium hydroxide. Among them, the viscosity reduction effect of barium dodecylbenzenesulfonate (BaDBS) is best as the dosage is 900 mg/L, the viscosity reduction rate is 89.0%, and the pour point is reduced by 5°C. Optical microscopy revealed the eutectic effect of crude oil flow improver and saturated hydrocarbon in heavy oil. FTIR and DSC were used to research the mechanism of small-molecule crude oil flow improver to reduce the viscosity of heavy oil.
