A new fluidics method to determine minimum miscibility pressure

Past, Present, and Future of Microfluidic Fluid Analysis in the Energy Industry

“…113 Other high pressure energy developments and applications include gas-oil ratio measurements of oil samples using microfluidics up to 37.6 MPa and 15 °C, 26 full pressure−temperature phase diagrams up to 6.7 MPa and 90 °C, 114 solubility, diffusivity, extraction pressure, miscibility, and contact angle of CO 2 + oil up to 13 MPa and 50 °C, 27 dew point measurements of CO 2 up to 14.4 MPa and 50 °C, 24 and minimum miscibility pressure measurements up to 35 MPa and 144 °C. 32 The other approach pursued was housing the chip in a pressure tank in which the chip and the interconnect experience relatively low-pressure differentials, with the surrounding hydraulics providing overburden pressure. The first reference of such an approach in the literature dates back two decades by Sohrabi et al 53,54,115,116 Application of a pressure vessel to allow operation of microfluidics at elevated pressures is also reported elsewhere.…”

“…12,163−165 Most notably, the recent commercialized microfluidic platform to measure the MMP can lower the threshold to obtain on-demand relevant data to improve the field operations' efficiency and impact the decision-making on CO 2 -EOR planning. 32,166 However, these tools require some additional development. Specifically with regard to temperature and pressure, CO 2 -based enhanced oil recovery and sequestration operations typically implement in geological formations with high pressure and temperature (∼100 MPa and 200 °C).…”

“…Mostowfi et al used a similar interconnect system with compression fittings and O-ring to study the phase behavior of hydrocarbon systems up to 4 MPa at 22 °C . Other high pressure energy developments and applications include gas-oil ratio measurements of oil samples using microfluidics up to 37.6 MPa and 15 °C, full pressure–temperature phase diagrams up to 6.7 MPa and 90 °C, solubility, diffusivity, extraction pressure, miscibility, and contact angle of CO 2 + oil up to 13 MPa and 50 °C, dew point measurements of CO 2 up to 14.4 MPa and 50 °C, and minimum miscibility pressure measurements up to 35 MPa and 144 °C .

“…Microfluidic measurements have been applied broadly in chemical, biological, and physical processes that are relevant to sensing, such as glass micromodels, capillary electrophoresis, and gas chromatography. In the area of fluid property measurement , microfluidics has enabled high accuracy measurements of phase and thermophysical properties such as bubble and dew points, − solution gas-oil ratios, solubility and diffusivity, − minimum miscibility pressures, , wax crystallization, , and asphaltenes precipitation. − Microfluidics has also been applied to resolve the pore-scale dynamics of in situ reservoir processes such as polymer flooding, , fluid rheology, chemical and foam injection, − gas flooding, − and thermal-solvent processes. − …”
