Review on application of nanoparticles for EOR purposes: A critical review of the opportunities and challenges

Deposition and precipitation of paraffin wax in pipelines are major problems in the production, transfer, storage, and processing of crude oil. To prevent complete clogging, it is necessary to minimize and remove deposited wax in pipelines and tubing. Significant research has been done addressing the mechanisms of wax formation and its composition. In this review, the status of research and perspectives on the occurrence and characterization of the paraffin wax that forms in crude oil developing wells and pipelines has been critically reviewed. Several approaches for detecting paraffin wax and managing wax formation damage during oil recovery were discussed. This review also highlighted the effects of temperature and crude oil type on wax formation.

Flow improvers for assured flow of crude oil in midstream pipeline - A review

Polymer flooding is a conventional EOR process. Application of nanoparticle to polymer is the current research area. These paper is aimed at studying the ability of different type’s polyacrylamide Nanoparticle to EOR. Some of the nanoparticles used are Magnesium oxide, Aluminium oxide, Zinc oxide etc. and are treated with silane for solving reservoir problem. Amongst them aluminium oxide, nickel oxide, hydrophobic silicon oxide and silicon oxide treated with silane are good agents for EOR by Ogolo et al. (SPE Saudi Arabia Section Technical Symposium and Exhibition 1–5, 2012) [1]. Ethanol is used as dispersing media for these nanoparticles for solving recovery problem by reducing Interfacial tension between oil and water. By using Aluminium oxide NP we can reduce oil viscosity while silicon oxide NP changes rock wettability. These results indicate that some of these nanoparticles are very effective [2] while used with polymer flooding and can be used to maximize recovery level and boost hydrocarbon production.
