Latest Patents: Among his recent innovations, Quirein developed a groundbreaking patent on "Permeability Anisotropy Assessment in Subsurface Anisotropic Formations." This invention offers methods and systems for logging data processing to evaluate permeability anisotropy effects. By using a permeability anisotropy model, a relationship is established between formation permeability anisotropy and resistivity anisotropy, applicable to both Transversely Isotropic (TI) and Anisotropic (BA) formations. The implementation allows for an integrated interpretation of resistivity anisotropy measurements alongside conventional permeability logs from various sensors.

Another significant patent is "Near Real-Time Return-on-Fracturing-Investment Optimization for Fracturing Shale and Tight Reservoirs." This system leverages sonic and density data to maximize return-on-fracturing-investment for shale fracturing. It calculates mechanical properties and closure stress of shale rocks to generate rock mechanical models for fracture modeling. The advanced system produces a neural network model that predicts a fracture productivity indicator and calculates return-on-fracturing-investment based on effective propped areas and lengths.
