Experimental and field applications of nanotechnology for enhanced oil recovery purposes: A review

Hydrodynamic Analysis and Cake Erosion Properties of a Modified Water-Based Drilling Fluid by a Polyacrylamide/Silica Nanocomposite during Rotating-Disk Dynamic Filtration

“…During filtration, solid particles in the drilling mud settle on the borehole wall and form a thin mud cake. The mud cake is the first barrier to prevent the increase of drilling mud filtration due to its low permeability. − Increasing drilling mud filtrates generally causes various problems such as damage to the oil production zones, fluid invasion into water-sensitive layers such as shales, and causing the drill string to be stuck due to thick mud cake formation. , Due to the importance of the topic, researchers have concentrated on nanoparticles (NPs) as a new additive to reduce fluid loss. − …”

Insight into Nano-chemical Enhanced Oil Recovery from Carbonate Reservoirs Using Environmentally Friendly Nanomaterials

“…Oil and gas companies have been attempting to improve oil recovery from mature reservoirs due to the increase in demand for fossil fuels and the reduction of unexplored hydrocarbon reservoirs in the world. , The exploration and exploitation of new reservoirs are riskier and costly compared with using enhanced oil recovery (EOR) methods. , There are primary, secondary, and tertiary methods for producing oil from oil reservoirs. During first two phases of oil extraction, only about 30–50% original oil in place (OOIP) of the crude oil can be produced depending on the characteristics of the reservoir. , Since only about 30–50% OOIP can be extracted from the reservoirs using the primary and secondary methods, tertiary (EOR) methods are given more attention. − There are several techniques for producing oil using the tertiary method, such as chemical injection, gas injection, thermal methods, and microbial methods .…”
