This study initially explores and reports the feasibility of surfactant foams to increase the efficacy of hydrogen storage in porous media. This is an essential field of study, which aims to tackle a primary concern of the future hydrogen-based economy-hydrogen storage, which is essential for the supply of energy during periods of intermittent supply. For this, storage of hydrogen in porous media is explored wherein non-uniform front advance and superior gas mobility reduce storage efficacy. To mitigate this concern, the foam was prepared using compressed air and a non-ionic surfactant, Triton X-100, in a guar gum solution of 4000 ppm. A fabricated sand-pack, prepared from the sand of size 100−180 μm, was used as porous media, in which hydrogen storage was evaluated for a fixed flow rate of 30 mL/h as a function of varying slug sizes. The inclusion of foam as mobility control fluid massively increased hydrogen storage by a factor of 1.5−2.7, with slug size 0.5 PV being the most desirable. Enhanced hydrogen storage was obtained when a slug of 0.3 PV or greater was used. Altering the gas flow rate from 30 to 60 mL/h reduced hydrogen storage by 34%. The presence of crude oil reduces foam stability, and the injection and storage of hydrogen gas in depleted oilfields having high volume of crude oil is thus not recommended. This study promotes the use of surfactant foams for subsurface storage of hydrogen in sandstone media by controlling the mobility of injected gas.

“…rGO with the content of 13–22% could not stabilize the foam, which was different from the results obtained by Liu. This may be due to the high reduction degree of the particles, and the increase of oxygen content would enhance the hydrophilicity and reduce the CO 2 -affinity [ 113 ].…”

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.

Surfactant-based foams have often been proposed as mobility control agents in enhanced oil recovery (EOR); however, their lack of stability under reservoir conditions has limited their field applications. This study aims at enhancing the efficiency of foam EOR by using a nanofluid composed of cocamidopropyl hydroxysultaine amphoteric surfactant and graphene quantum dot (GQD) nanoparticles extracted from Wyoming coal. Macroscale foam flooding experiments were conducted under challenging reservoir conditions (3500 psi, 115 °C, and 200,000 ppm brine salinity) to represent unconventional oil formations such as Bakken. Foam was generated through the coinjection of nanofluid and methane in strongly oil-wet core samples of different lithology (Berea sandstone, Edward limestone, and Minnesota Northern Cream (MNC) limestone), and the impact of foam quality was investigated in each outcrop. The nanofluid resulted in improved bulk foam stability due to the generation of finely structured foam of a low average bubble size (277.83 μm) and thick lamellae (98.91 μm). The in situ formation of stable foam during the core flooding tests was reflected by an improved apparent viscosity that was greatly influenced by the petrophysical properties of the rocks (i.e., pore size, pore size distribution, permeability, and wettability condition). For instance, the process of bubble generation and collapse was significantly noticed in the Edward core sample as a result of its heterogeneous pore size and nonuniform pore size distribution compared to Berea and MNC core samples. On the other hand, foam texture and the number of generated lamellae films were controlled by the fraction of gas injected (foam quality). At 60% foam quality, the foam had a very fine texture, resulting in an increased pressure gradient across the core, reduced gas mobility, and therefore improved oil sweep efficiency by diverting more gas to inaccessible oil-filled pores. As a result, the incremental oil recovery due to foam flooding was 11.5, 16.2, and 7.3% for the Berea, Edward, and MNC core samples, respectively. This study provides an in-depth understanding of the mechanisms that contribute to foam EOR in various oil-wet porous media utilizing novel nanofluid formulations.
