Graphene and its derivatives, with their unique two-dimensional structures and excellent physical and chemical properties, have been an international research hotspot both in the research community and industry. However, in application-oriented research in the oil and gas industry they have only drawn attention in the past several years. Their excellent optical, electrical, thermal and mechanical performance make them great candidates for use in oil and gas exploration, drilling, production, and transportation. Combined with the actual requirements for well working fluids, chemical enhanced oil recovery, heavy oil recovery, profile control and water shutoff, tracers, oily wastewater treatment, pipeline corrosion prevention treatment, and tools and apparatus, etc., this paper introduces the behavior in water and toxicity to organisms of graphene and its derivatives in detail, and comprehensively reviews the research progress of graphene materials in the upstream oil and gas industry. Based on this, suggestions were put forward for the future research. This work is useful to the in-depth mechanism research and application scope broadening research in the upstream oil and gas industry.

“…Enhanced oil recovery (EOR) by waterflooding is considered the most practical and cost-effective way to extract residual oil by manipulating the properties of reservoir rocks and trapped oil. − Some factors including oil saturation, capillary forces, and low sweep efficiency as a result of rock heterogeneities may lead to reduction or failure of EOR methods for oil extraction.

Carbon dots (CDs) as a zero-dimensional family of nanocarbon provide a great potential for enhanced oil recovery (EOR) owing to the outstanding physicochemical and optical properties for manipulation and detection of the water−rock−oil ternary system. Herein, CDs were synthesized with citric acid and urea via an easy and fast microwave-assisted carbonization method and characterized by atomic force microscopy (AFM), dynamic light scattering (DLS), ζ-potential, and thermogravimetric analysis (TGA) to prepare nanofluids as a tracing and flooding agent in the oil field. The as-synthesized CDs with a quantum yield of 35% demonstrated a long-time fluorescence emission stability in a brine solution with 50,000 ppm salt concentration for more than 3 months to be used as a tracer for on-site water monitoring to manage and optimize oil production by following the flow path in the oil reservoir. Moreover, the oil sweeping efficiency of CDs on the carbonate rock reservoir was evaluated by controlling the viscosity, wettability alteration, and interfacial tension, and a displacement mechanism was proposed by following the nanofluid flow on the micromodel pattern. Experimental results showed convenient water traceability and around 33% oil recovery for the prepared nanofluid with a low concentration of CDs (ca., 500 ppm).

“…Even if CQDs are being implemented as tracers in the oil and gas industry, ,,− there are no reports, to the best of our knowledge, of CQDs being produced using a domestic microwave oven and Mortiño ( Vaccinium Meridionale Swartz ) extract, then used as green tracers. As mentioned above, CQDs are potential tracers for the oil industry.…”

The main objective of this study is to develop nanotechnology-based materials, specifically carbon quantum dots (CQDs), as alternative nonpolluting, nontoxic, and easily manipulated tracers for the oil industry using an easy and rapid synthesis from Mortinõ (Vaccinium meridionale Swartz) extract, a process that was evaluated in the laboratory and subjected to a Colombian oil field trial. The CQDs were synthesized using an easy and rapid microwave-assisted carbonization (MWC) methodology involving aqueous natural extraction in the presence of an organic nitrogen precursor. A displacement test at reservoir conditions in a porous media was used for evaluating CQDs retention, and a breakthrough curve with a CQDs saturation of around 1 pore volume injected was obtained, indicating that the CQDs could be completely removed from the porous media with null retention due to a poor interaction with the formation and preferential affinity to the aqueous phase. Fluorescence tests showed that quantification of the synthesized CQDs could be achieved for up to 1 ng L −1 . Coreflooding tests at reservoir conditions were performed under two scenarios: (1) monophase coreflooding (the core was saturated with water) and (2) biphasic coreflooding (at residual saturation of crude oil). The results showed that the CQD S behave excellently within these outlines and are not affected by the presence of crude oil, obtaining a breakthrough that is almost ideal for a tracer. A CQDs field trial in Colombia was conducted by injecting 20 kg of the nanomaterial at a concentration of 500 000 mg L −1 . The CQDs were analyzed in 10 producer wells, showing that they are useful as interwell tracers and the different interconnections between the different wells in the field were stablished. This study places the technology at a technology readiness level (TRL) of around 8, opens a broader landscape for the use of nanotechnology in the oil industry, and maintains Colombia as a pioneer in the application of nanoparticles and nanofluids under field conditions.
