Chapter 1: Techniques
BPFlux™ employs a multi-faceted approach to analyzing flux damage, integrating several key techniques:
Advanced Reservoir Simulation: BPFlux™ utilizes cutting-edge reservoir simulation software incorporating detailed geological models, fluid properties, and complex flow dynamics. These models go beyond standard simulations to explicitly account for the evolving permeability and wettability changes associated with flux damage. This includes simulating the transport of fines, asphaltenes, and other damaging agents within the reservoir. The simulations are calibrated and validated using production history matching and core data.
Geomechanical Modeling: The system incorporates geomechanical modeling to assess the impact of pressure changes and stress alterations on fracture propagation and closure. This is particularly important in fractured reservoirs where flux damage can significantly impact fracture conductivity. The models incorporate stress-dependent permeability changes and account for the interplay between fluid flow and rock mechanics.
Microscopic Imaging and Analysis: BPFlux™ integrates high-resolution microscopic imaging techniques (e.g., scanning electron microscopy, confocal microscopy) to directly visualize pore-scale damage mechanisms. Image analysis software quantifies pore throat size distributions, surface area changes, and the distribution of damaging agents, providing crucial input for the reservoir simulation and geochemical analysis.
Geochemical Analysis: Detailed geochemical analysis of core samples and produced fluids is used to identify the type and extent of flux damage. This analysis focuses on identifying the chemical composition of fines, asphaltenes, and other damaging agents, as well as changes in the wettability of the reservoir rock. Stable isotope analysis can provide insights into fluid flow pathways and the origins of damaging components.
Chapter 2: Models
BPFlux™ relies on a suite of interconnected models to provide a comprehensive assessment of flux damage:
Damage Propagation Model: This model simulates the spatial and temporal evolution of flux damage within the reservoir, taking into account the factors described in the techniques section. It predicts the changes in permeability and wettability as a function of fluid flow and the properties of the damaging agents.
Wettability Alteration Model: This model specifically addresses changes in reservoir wettability, a crucial factor in flux damage. It incorporates the effects of chemical interactions between fluids and rock surfaces, leading to changes in the oil-water contact and the subsequent impact on permeability.
Fracture Conductivity Model: This model simulates the changes in fracture conductivity due to closure or plugging. It accounts for the mechanical properties of the rock, the stress state, and the presence of damaging agents within the fracture network.
Integrated Model: All individual models are coupled and integrated within a comprehensive framework to provide a holistic representation of flux damage. This allows for a synergistic understanding of how different damage mechanisms interact and influence overall reservoir performance.
