Asphaltene deposition is a major challenge in the petroleum industry, reducing production and increasing costs. Recently, nanoparticles and novel nanocomposites have emerged as an effective strategy for controlling this phenomenon. This review examines the role of nanoparticles in inhibiting asphaltene adsorption, precipitation, and sedimentation, emphasizing common nanomaterial characterization techniques. Analytical methods include XRD, FTIR, SEM, TEM, EDX, and BET surface area analysis. Langmuir and Freundlich adsorption isotherms are also presented to model the interactions. Results show that nanocomposites such as EC-NCs and ZZC exhibit high adsorption capacities (109 and 124 mg/g, respectively) and can reduce asphaltene precipitation by up to 50%. This review provides a fundamental step toward designing efficient adsorbents and optimizing enhanced oil recovery processes.
