Production Pressure in Complex Socio-Technical Systems: Analysis, Measurement, and Prediction
… systems (STSs). This research mainly focuses on production pressure (PrP) which is considered as one of the main negative outcomes of overprioritizing the efficiency aspect of STSs. This work seeks to introduce novel methodologies for assessing PrP in real time for the purpose of mitigating its …

Experimental and mathematical modeling of foamy-oil evolution and flow in the primary production and CO₂-based cyclic solvent injection
… tests in a PVT cell and differential fluids production (DFP) tests in a sandpacked physical model were performed. The experimental results showed that the solvent exsolution from each heavy oil-solvent system in the porous media occurred earlier than that in the bulk fluids. In addition, the …

Automated monitoring and systemic analysis of workers' safety behavior in construction operations
… factors (e.g., safety program, safety culture, production pressure). Behavior measurement also turns out to be significantly correlated to safety outcomes (e.g., incident rates). To this end, an in-depth understanding of workers’ behavior has tremendous potential to contribute to the prevention …

Experiment Study of Non-Equilibrium Phase Behavior and Effect of External Vibration on Heavy Oil Production
… the influence of external vibration on heavy oil production performance. The first experiment was to use a Constant Composition Expansion and Compression (CCEC) tests to determine the pseudo-bubble point pressure at low (T = 15°C) and high (T = 75°C) temperature environment with three different …

Extraction of turbomachinery loss mechanisms from high-fidelity simulations
… was driven by separation bubbles on both pressure and suction surfaces and structures associated with the separation bubbles were identified to contribute to raising the entropy of the flow at higher rates than the non-structure flow in the same regions. For the case of the impeller, two …

Performance Evaluation of an Enhanced Cyclic Solvent Process (ECSP) for Thin Heavy Oil Reservoirs
… of the ECSP in the laboratory- and field-scale. Pressure-volume-temperature (PVT) tests have been performed for the solvent(s)-heavy oil systems. Then, the PVT properties are simulated by using the CMG WinProp module. For the CH4-C3H8-heavy oil mixture, the swelling factor of heavy oil maintains …
