Innovative Molecular Simulation Algorithm Enhances Oil Recovery Strategies
A pioneering study has introduced a sophisticated algorithm for simulating molecular behavior of oil, which promises to enhance techniques for oil recovery and filtration. This groundbreaking research appears in the journal Colloids and Surfaces A: Physicochemical and Engineering Aspects.
The Importance of Accurate Oil Simulation
Understanding how oil behaves within various environmental contexts, especially porous media, is critical. However, existing models often oversimplify oil composition through single-component frameworks, compromising reliability.
A collaborative team from Skoltech, MIPT, AIRI, and MSU has developed an innovative approach to appropriately model the porous interiors of the Earth. Their focus on determining the contact angle between quartz surfaces when interacting with both oil and water led to an advanced algorithm that incorporates a detailed 15-component representation of crude oil based on empirical data.
Detailed Dynamics of Oil-Water Interaction
The latest algorithm constructs a model mimicking slit-shaped pores created by quartz plates with intermingled layers of water and oil. Research indicates that within these confined spaces, the liquid forms a droplet resembling a flattened cylinder bounded by pore walls. The crucial measurement here is the contact angle at four distinct three-phase interaction points around this droplet; this angle is calculated as an average across these points.
Petr Khoventhal, leading author and Petroleum Engineering Ph.D. student at Skoltech stated: “The innovative approach we’ve developed allows for precise determination of angles throughout each simulation step without requiring adjustment for methane or dissolved substances like water.” He added that this efficiency aids in processing large datasets while maintaining straightforward controls over calculations.
Significance of Multi-Component Inclusion
A standout feature of this research is its incorporation of diverse components found in crude oils—especially asphaltenes alongside methane—ensuring representations mirror real-world molecular interactions more accurately.
Ilya Kopanichuk from MIPT’s Computational Physics Center explained that “Our findings emphasize how vital asphaltenes are when analyzing wettability factors since methane often coexists with oil making it significant even by mass.” Ignoring such key components would skew simulation outcomes significantly compared to actual fluid characteristics.
Diverse Factors Affecting Contact Angle Measurements
The researchers employed their new algorithm to scrutinize various parameters impacting contact angles during simulations involving temperature changes—the results demonstrated that rising temperatures tend reduced angles while increased shale levels contributed larger values reflecting lower wettability tendencies.
Moreover, it was found that high salinity levels lead to sharper decline angles whereas ornate contents coupled with pressure variations were shown to minimally influence measurements overall—indicating there exists intricate dependence on temperature variables along with brine salinity compositions affecting wetting properties practically applicable within operational frameworks like injected brines adjustments.< / p >
