“…Is there another way for the RIEM to reduce the formation permeability besides plugging the pores? It is generally believed that the surfactants in the oil-based mud that invades the rock matrix are capable of changing the natural wetting state from water-wet to oil-wet, thus impeding the flow of hydrocarbons through the rock matrix during production (Chen et al, 2006;Cuiec, 1989;Gant and Anderson, 1988;McDonald and Buller, 1992;Patel and Growcock, 1999;Skalli et al, 2006;Yan et al, 1993;Yan and Sharma, 1989).…”

“…However, these characteristics are detrimental to well completion and workover operations because they lead to difficult filter-cake cleanup, poor cementing, and the retention of oil on cuttings (Davison et al, 2000;Hemphill and Larsen, 1996;Malachosky et al, 1993;Oakley et al, 1991;Saasen et al, 2001;Yan, 2013). Fluids that are highly oil-wetting also tend to alter the wettability of the drilled formation, resulting in formation damage (Ballard and Dawe, 1998;Chen et al, 2006;Cuiec, 1989;Fjelde, 2009;Gant and Anderson, 1988;McDonald and Buller, 1992;Skalli et al, 2006;Yan et al, 1993;Yan and Sharma, 1989). For these reasons, the ability to reversibly control the emulsion and/or wetting characteristics is beneficial to the design of drilling and completion fluids.…”

Formation damage has the potential to impair and weaken reservoir productivity and injectivity, causing substantial economic losses. Oil and gas wells can be damaged by various mechanisms, such as solid invasion, rock–fluid incompatibilities, fluid–fluid incompatibilities, and phase trapping/blocking, which can reduce natural permeability of oil and gas near the wellbore zone. These can happen during most field operations, including drilling operations, completion, production, stimulation, and enhanced oil recovery (EOR). Numerous studies have been undertaken in recent years on the application of nanotechnology to aid the control of formation damage. This review has found that nanotechnology is more successful than traditional materials in controlling formation damages in different phases of oil and gas development. This is facilitated by their small size and high surface area/volume ratio, which increase reactivity and interactivity to the adjacent materials/surfaces. Furthermore, adding hydrophilic nanoparticles (0.05 wt %) to surfactants during EOR alters their wettability from 15 to 33%. Wettability alteration capabilities of nanoparticles are also exemplified by carbonate rock from oil-wet to water-wet after the concentration of 4 g/L silica nanoparticles is added. In addition, mixing nanoparticles to the drilling fluid reduced 70% of fluid loss. However, the mechanisms of impairment of conductivity in shale/tight formations are not consistent and can differ from one formation to another as a result of a high level of subsurface heterogeneity. Thus, the reactivity and interaction of nanoparticles in these shale/tight formations have not been clearly explained, and a recommendation is made for further investigations. We also recommend more nanotechnology field trials for future research because deductions from current studies are insufficient. This review provides more insights on the applications of nanoparticles in different stages of oil and gas development, increasing our understanding on the measures to control formation damage.

“…When cationic surfactant are used in oil-based mud, they absorb onto Smectite clays to allow it to be dispersed in organic media. This treatment prevents the clay from dispersing in water [17][18][19]. Therefore, cationic surfactants are very effective in reducing the dispersion of shale, to increase solid tolerance, reduce high temperature-high pressure filtration properties, improve rheological characteristics, and increase the drilling rate.…”

A new additive cationic surfactant for drilling fluid was synthesized by alkylation of coal tar phenol with tetradecyl alcohol; then, the alkyl phenol reacts with formaldehyde and amine to produce the Mannich base product. This product was reacted with sodium chloroacetate to produce the cationic surfactant; the structure of the synthesized surfactant was confirmed by FTIR analysis, evaluation of the prepared surfactant by surface properties such as surface tension, emulsification power, and wetting power. The prepared cationic surfactant showed good results when utilized in the formulation of both oil-based mud and synthetic-based mud as the primary emulsifier.
