Microfluidics presents an unprecedented opportunity to understand fluid properties and phase measurements at extreme conditions relevant to energy applications. Since the 1950s, when a simple micromodel system was built to visualize fluid behavior in porous media, microfluidics has matured and has been adapted to help address the biggest fluid challenges within the energy industry. Modern microfluidic systems are robust at high temperatures and pressures and can provide phase property analyses competitive with the most established bulk methods. In contrast to bulk methods, microfluidic approaches offer advantages in speed, cost, control, and sample size. Here, we review and highlight the past and present of microfluidic-based fluid analysis and look ahead to future applications and the opportunity presented by the energy sector transition ahead.

“…In commercial compositional simulators, it has been difficult to accurately determine the residual oil saturation and there is no facility for the user to define a realistic residual oil saturation which does not vaporize. The residual oil saturation affects the accuracy of the oil recovery efficiency and impacts on the statistics and information from the recovery process during design stage [13,15].…”

Recovery efficiency is very important in enhanced oil recovery (EOR) processes as it helps in the planning, design and selection of EOR methods that will be technically and economically feasible. In this study, Simulation on hot CO 2 flooding is conducted using data from Niger Delta heavy oil reservoir. The compositional simulation process was carried out in ECLIPSE 300 compositional oil simulator. The recovery efficiency and injection calculations were modeled and simulated in Matlab. Numerical equations enabled the determination of the residual oil saturation and the consequent calculation of the injection and recovery before and after solvent breakthroughs. CO 2 of 0.095cp viscosity was injected at pressure of 3500 psia and 200°F to heat up the reservoir at payzone and reduce the viscosity of the reservoir oil at in-situ reservoir condition. The reservoir oil initially at 14.23cp at initial reservoir temperature and pressure was heated and reduced to a viscosity of 2cP making the oil mobile and amenable to flow. Results show recovery of the process before and after breakthroughs. CO 2 breakthrough was realized after 221 days of the flooding process. Of the 2461.2 ft distance from the injection wells to the producer well, CO 2 reached only a distance of 100 ft at breakthrough. Out of the 2.77 PV total volume of CO 2 injected in the flooding process, 0.1222 PV of CO 2 was injected as at breakthrough. The recovery efficiency result show that the displacement efficiency at CO 2 breakthrough and at the end of the flooding process are 15.17% and 78.63% respectively while the areal sweep efficiency at CO 2 breakthrough and at the end of the flooding process are 44.02% and 93.32% respectively. The low displacement and areal sweep efficiency at breakthrough were due to early breakthrough of CO 2 which did not allow sufficient period of time for the CO 2 to contact considerable portions of the reservoir given its viscous nature. Furthermore, at CO 2 breakthrough time, the injected hot CO 2 had no sufficient time to soak the reservoir and reduce the viscosity of the oil; as such only a small fraction of the in-situ oil became mobile. An overall recovery efficiency of 73.33% realized in the flooding process signifies favourable flooding design hence is recommended for the development and recovery of Niger Delta heavy oilfield.

The fast flow rate of water through nanochannels has promising applications in desalination, energy conversion, and nanomedicine. We have used molecular dynamics simulations to show that the water molecules passing through a wide single-walled carbon nanotube (CNT) cavity get aligned by flow to have a net dipole moment along the flow direction. With increasing flow velocity, the net dipole moment first increases and eventually saturates to a constant value. This behavior is similar to the Langevin theory of paraelectricity with the flow velocity acting as an effective aligning field. We show conclusively that the microscopic origin of this behavior is the preferential entry of water molecules with their dipole vectors pointing inward along the CNT axis.
