“…Utilizing either miscible or immiscible gases depends on prevailing conditions in the reservoir, pressure and temperature of the formation, and the combinations of the crude oil. Implementing of hydrocarbon gases, liquefied petroleum gas (LPG), CO2, and N2 are usual for displacing the oil, during this process [57].…”

As we all know, numerous methods have been invented for better managing of the reservoirs to recover the trapped oil from them as much as possible. These techniques included primary techniques that were implemented primarily at the beginning of this industry. As these techniques were not effective enough, secondary techniques, like; water flooding and gas injection methods were created and the amount of recovered oil were increased, as well. On the contrary, the demand for more oil was raised up and it was felt that much more effective techniques are necessary. It resulted to creation of Enhanced Oil Recovery Techniques and these techniques are included; thermal methods (steam injection, steam assisted gravity drainage and in-situ combustion), Chemical methods (alkali flooding, surfactant flooding, polymer flooding, foam flooding, and combination of alkali-surfactant-polymer flooding), and microbial EOR. The most promising technique is microbial EOR because of being cost-effective and ecofriendly. GEMEOR (Genetically Engineered MEOR) and EEOR (Enzyme Enhanced Oil Recovery) are two new trends of MEOR that own potential hopes in petroleum industry.

“…Their main goal is to quantify the asphaltene precipitation, identify the AOP, and verify whether the asphaltene formation process is reversible . The most popular methods to measure asphaltene precipitation and AOP are: (1) the light scattering technique (LST), − (2) the gravimetric method, , (3) the acoustic resonance technique (ART), ,, (4) the filtration technique, , and (5) the solid detection system (SDS). In the LST, the transmittance of near-infrared light is measured when it goes through the CO 2 –oil mixture.…”

“…The asphaltene precipitation measuring capability of the LST is achieved by coupling a HPHT pressure–volume–temperature ( PVT ) cell with an optical microscope. Many investigators have tested the accuracy of the LST for determining AOP. ,− However, verifying reversibility in real-time is impossible because a precipitated asphaltenes sample is taken from the system to the microscope. ,,, …”

Net-zero carbon emission pledges by 2050 are prompting researchers to investigate alternatives to store CO 2 safely. Subsurface CO 2 storage faces many challenges, especially when the geological space is a depleted oil reservoir. A crucial problem is the newly formed asphaltenes during CO 2 injection that could limit or even block the rock-effective zone for gas storage. In this work, a novel pressure−volume−temperature cell and a solid detection system are used to measure the phase behavior, asphaltene onset pressure, and asphaltene precipitation. Results show four different equilibrium phases during the isothermal depressurization processes. Likewise, asphaltene precipitation increases with CO 2 fractions and decreases with temperature, reaching its maximum at the bubble point. More importantly, the redissolution of asphaltene particles back into the solution is observed, revealing the formation process reversibility at certain conditions (25 mol % CO 2 at 60, 90, and 120 °C; 35 mol % CO 2 at 90 and 120 °C). The Peng−Robinson equation of state model is employed to model the fluid phase, while the solid phase equilibrium is modeled with a solid model. A new correlation for the asphaltene molar volume is proposed, which predicts the experimental data with an AARD of 0.7%.
