Sand Production in Oil Wells

The main problem associated with sand production in oil wells is the potential for wellbore instability and sand accumulation, which can lead to reduced oil production and even well abandonment.

Limitations of Numerical Models

Continuum-based numerical models are insufficient for predicting sand production because they do not accurately capture the complex, discrete nature of sand transport.

Advantages of Discrete-Element Methods

Discrete-element based approaches have a key advantage over continuum-based models for predicting sand production, as they can model the discrete behavior of individual sand particles and their interactions.

Thesis Focus and Importance

The primary focus of the Ph.D. thesis mentioned in the text is likely the development of a numerical model for predicting sand production in oil wells.
Studying the sand production process is crucial for hydrocarbon production because it allows for the development of strategies to mitigate sand-related issues and optimize oil recovery.

Research Aim and Methodology

The main aim of the research described in the text was to develop and validate a numerical model for predicting sand production in oil wells.
The research involved the use of the parallel-bond model (PBM), which was significant for capturing the mechanical behavior of the sand-rock interface.
The CFD-DEM model was validated through simulations of small-scale experiments and industrial-scale scenarios.

Funding and Contributions

Part of the research was funded by the [funding agency name].
Dr. Marcos Arroyo and Professor Antonio Gens contributed to the development of the PBM and its application in the research.
