Investigation of coupled thermo-chemo-mechanical processes for safe carbon geological storage
Safe and permanent CO₂ storage in geological formations requires reservoir geomechanical stability. Injection of CO₂ into the subsurface changes the local pore pressure and, further, alters the effective stresses due to ...
A tri-axial electromagnetic induction tool for hydraulic fracture diagnostics
The monitoring and diagnostics of induced fractures are important for the real-time performance evaluation of hydraulic fracturing operations. Previous electromagnetic (EM) based studies show that single backbone tri-axial ...
Fault reactivation and CO₂ migration in carbon storage
Injection of carbon dioxide (CO₂) underground is considered one of the possible solutions to address the increasing concentration of greenhouse gases in the atmosphere. Long-term integrity and practical storage of CO₂ is ...
Investigation of pulse fracturing via peridynamics modeling and simulation
Pulse fracturing is an alternative stimulation technology to enhance production from oil and gas wells, especially ones in fractured hydrocarbon reservoirs. This stimulation generates multiple radial fractures that initiate ...
Experimental investigation of surfactant flooding in fractured limestones
Carbonates are important candidates for enhanced oil recovery, but recovering oil from oil-wet fractured carbonate reservoirs is challenging. Waterflooding bypasses the rock matrix and recovers little oil. Chemical enhanced ...
Experimental investigation of low interfacial tension displacements in oil-wet, fractured micromodels
The objective of this work was to determine, using a microfluidics platform, if surfactants that reduce interfacial tension would produce oil from oil-wet, fractured systems in both static conditions (where no injection ...
Modeling of hydraulic fracture propagation and height growth in layered formations
Microseismic observations and other field data suggest that hydraulic fractures are often not contained within a single layer. Acoustic log data show rock mechanical properties typically vary significantly between layers, ...
Modeling of tubing pickling in conjunction with matrix acidizing treatments
Study of geochemical interactions during chemical EOR processes
Geochemical interactions of injected fluids with reservoir fluids and minerals determine the fate of the injected species in the porous media. In addition, these interactions could result in affecting the properties of the ...
Experimental studies in hydraulic fracture growth : fundamental insights and validation experiments for geomechanical models
Novel experimental capabilities to study hydraulic fracturing in the laboratory are developed and utilized in this research. Fracturing experiments are conducted using two-dimensional (2-D) test specimens that are made ...
