In oil production, sand detached from unconsolidated rock formations may obstruct flow passages, erode surfaces and lodge in equipment mechanisms, leading to malfunctions and inefficiency. This white paper post demonstrates the capability of Rocky DEM to adequately simulate solid retention by standalone screens (SAS) applied in sand management operations.
The study evaluates the efficiency and application viability of premium screens. Simulations performed in the Research Center for Rheology and Non-Newtonian Fluids (CERNN) at the Federal University of Technology – Paraná (UTFPR) with Rocky DEM coupled to Ansys Fluent provide groundbreaking information quantifying the efficiency of each SAS.
The white paper provides approaches on:
- Efficiency of SAS in terms of retained mass, retained particle PSD and filtered PSD
- Reverse Dutch Twill Weaves (RDTW) and Dutch Twill Weaves (DTW)
- Representative Elementary Volume (REV) for particle retention
- Fluid flow simulation
- CFD-DEM coupling
