I study fluid flow in porous media by using experimental and mathematical techniques for applications in hydraulic fracturing and enhanced oil recovery. My current research areas include:
Understanding Rock-Fluid Interactions
- Measurement of rock wettability and its correlation with other petrophysical properties
- Characterization of rock pore structure using SEM and AFM analyses
- Visualization of rock- gas -oil interactions at reservoir conditions
- Laboratory simulation of gas flooding and huff ‘n’ puff processes for improving oil recovery from tight oil reservoirs
- Evaluation of gas-oil interactions at the bulk phase conditions using PVT analysis
- Characterizing bulk-phase behaviour of surfactant solutions with oil
- Effect of fracturing fluid formulation on oil recovery from unconventional reservoirs
- Laboratory evaluation of surfactant flooding in low-permeability reservoirs
Complementary Flowback and Post-flowback Production Data Analysis for Uncertainty Reduction in Fracture Characterization
- Analysis of extensive flowback data from multi-fractured horizontal wells
- Development of models and procedures for analyzing water/oil/gas flow rates and pressure measured during flowback operations
- Analysis of flowback rate and pressure data to forecast post-flowback production
- Investigation of the effects of natural/secondary fractures on flowback and post-flowback production
Fracture Characterization by Analyzing Produced Flowback Salts
- Chemical analysis of the water produced during flowback operations
- Development of a comprehensive workflow to characterize the fracture network from the salt concentration profiles
- Investigating the reasons behind poor water recovery after fracturing operations and the possibility of recycling/reuse of flowback water
Development of Rate-Transient Models for Production Data Analysis
- Modelling fluid flow through matrix, secondary fractures, and primary hydraulic fractures
- Extension of the conventional dual porosity models to triple porosity models to account for secondary fractures communicating with the induced hydraulic fractures
