Asphaltene Precipitation/Deposition Estimation and Inhibition through Nanotechnology: A Comprehensive Review

Asphaltene precipitation/deposition is considered a problem of formation damage, which can reduce the oil recovery factor. In addition, asphaltenes be deposited in pipelines and surface installations, causing serious complications guaranteeing runoff, decreasing production wells. The precipitation minimized by reducing flowrate or using chemical inhibitors. Analyzing stability trend petroleum vital for guarantee flow. For this purpose, several experimental numerical methods have been proposed. Once risk established, strategies formulated prevention diagnosis deposition problems training. tests performed with dead oil, available wellhead, help understanding behavior asphaltenes. This review aims to present (i) related asphaltenes; (ii) thermodynamic models asphaltene precipitation; (iii) inhibition, control, removal techniques nanoparticles.
