Abstract
A variety of chemicals are used in various stages of oil exploitation to ensure the normal progress of exploitation and improve the efficiency of oil recovery. However, most of the conventional petroleum-based chemicals are non-biodegradable, which will remain as wastes after applying, leading to serious environmental menace. In recent years, cellulose nanomaterials have attracted extensive interest due to their renewable and biodegradable features, as well as excellent chemical, mechanical, and rheological properties. This review comprehensively summarizes recent advances in exploring cellulose nanomaterials for oil exploration applications. Firstly, the preparation and properties of cellulose nanomaterials are briefly introduced. Then, the applications of cellulose nanomaterials in different petroleum exploitation processes, including drilling, cementing, and enhancing oil recovery are systematically discussed. Finally, the perspectives and challenges of cellulose nanomaterials for oil exploration applications are provided. It is expected that cellulose nanomaterials will be developed as promising oilfield chemicals for large scale application.
