Among the existing enhanced oil recovery (EOR) techniques, the alkali−surfactant−polymer (ASP) flooding EOR technique has been proven to recover an additional 25−30% of the original oil in place, which is relatively higher than that of the other chemical EOR techniques. The field operations involved during the water flooding (WF) and ASP flooding EOR processes are highly CO 2 emissive, leading to increased global carbon footprint. However, due to the uncertainties associated with the operational parameters, the decarbonization of the ASP flooding EOR process becomes unreliable and challenging. Hence, the objectives of the present study are to decarbonize the ASP flooding EOR process using hydrogen and to improve the reliability of the decarbonization process under uncertain conditions. To decarbonize the ASP flooding EOR process, in the present study, CO 2 emissions from all the associated field operations were quantified, and subsequently, the major CO 2 contributing operations were identified for decarbonization. Followingly, to quantify the uncertainty in decarbonization of ASP flooding EOR process, the global sensitivity analysis was performed using Sobol's method. Finally, from these studies, efficient operational strategies were proposed to make the ASP flooding EOR process a low-carbon emissive EOR technique under uncertainty. It was observed that the ASP flooding EOR process emitted 1.95 times more CO 2 than did water flooding process for producing a barrel of oil. The present study also suggests that by using progressive cavity pumps for artificial lift systems and brackish water reverse osmosis water treatment technique can reduce about 24% of total CO 2 emissions during the ASP flooding EOR process. Moreover, it was also estimated that the manufacturing of alkali, surfactant, and polymer chemicals alone contributed 55.3% of total CO 2 emissions during the ASP slug injection stage. From the scenario analysis, it was found that the ASP chemical slug injection stage caused more uncertainty in estimation of CO 2 emissions and hydrogen requirement for decarbonization.

The pulse plasma-based shockwave (PPBSW) technology has become very noticeable across many areas, such as the food, mining, and oil and gas industries. The present study deals with the impact of PPBSW on the pore network and connectivity of rock samples generated through the developed tool. It also provides detailed insight regarding the pore structure using micro-CT analysis. The study was performed on Indian sandstone and Berea sandstone samples under a set confining pressure using the suitable dimensions of the fabricated tool, enabling rapid deployment inside the well. This may assist in deciding the role of this technology in various oil field operations affecting hydrocarbon recovery. Core samples were characterized by mineral content, ultrasonic velocities, physical appearance, and microstructural evaluation before exposure to PPBSW. Core samples were subjected to varying shockwave pulses. Postexposure rock samples were analyzed by using ultrasonic measurements and microstructure evaluation. The results revealed that these shockwave pulses significantly impacted various parameters, such as porosity, ultrasonic velocities, physical appearance, and the microstructure of exposed core samples. The damage factor/coefficient of rocks was affected after the exposure. It was noticed that the impact increased as the number of pulses increased. The physical appearance of the field samples after the exposure revealed that, as the number of pulses increased, the chipping of the matrix, the creation of new voids, and the connectivity of pore space also increased, whereas micro-CT scans of the Berea sandstone samples revealed that porosity and connectivity between the pores were increased as the number of pulses was increased. One of the field samples was exposed to 100 pulses during which fractures were developed. In the presence of natural fractures in the rock, the creation of microfractures could easily connect to them. It may increase the permeability, eventually creating better fluid flow through porous layers and increasing hydrocarbon recovery. Thus, this technology is more suitable for creating voids and microfractures near the wellbore.

Streamer discharge is a very complex multi-scale and multi-physics coupling process, and there is no accurate model that can describe its development. In this paper, a two-dimensional axisymmetric fluid model is established in COMSOL to simulate and study the effects of the applied voltage amplitude, the discharge gap distance, the rising edge of pulse voltage, and hydrostatic pressure on the development of the positive streamer discharge at a needle-plate electrode in water under a nanosecond pulse voltage. The results show that increasing the voltage amplitude, decreasing the pulse rise time, and narrowing the discharge gap all increase the electric field strength of the streamer, thereby affecting the electron density of the plasma channel, among which changing the discharge gap has the greatest effect on the electron density. And under the gap of 3 mm, the peak electron density can reach 3.76 × 1023 m−3; if the discharge gap is narrowed to 1 mm, the peak electron density is reduced to 1.20 × 1023 m−3. In addition, hydrostatic pressure and water molecule spacing are closely linked. Increasing the hydrostatic pressure decreases the electric field strength and the peak electron density in the plasma channel, and its effect on the peak electron density saturates with increasing hydrostatic pressure.
