Develop a multilayered ground-surface water model for simulating flow under 500-year flood conditions along the US Army Corps levee network. The model utilized to determine uplift pressure for design of foundation slab of multistory building and to establish the safe basement depth in close proximity to the levee.

Conducted three-dimensional modeling for design of multiple collector wells, each capable of producing in excess of 6 million gallons per day. Transient simulation under normal and dry conditions were conducted in order to assess impacts of pumpage on stream flows, and to determine maximum yield of the high capacity wells.

Developed groundwater flow model of the interconnected alluvial, Memphis, and Wilcox aquifers within the Mississippi embayment aquifer system. Conductive predictive simulations for wellfield design to meet water demand for 25 years, which is expected to triple over current rates.

Constructed groundwater model for designing a dewatering well network to protect interstate highways I-70, I-54, and I-90 from flooding in southeast Illinois. The nineteen million gallon per day well network was designed to maintain safe operating conditions along the highways and associated infrastructure under 500-year flood stage conditions in the Mississippi River.

Developed a regional multi-aquifer groundwater model spanning 19 counties in northeast Florida and southeast Georgia. The model simulates complex subsurface hydrodynamics in four aquifers, which extend to 2,500 feet below ground, and contain water quality ranging from fresh to relict-seawater. The model was used as the primary technical tool by the District for Water Supply Needs and Sources Assessment mandated by the Florida legislature for managing water resources over a 25-year planning horizon.

Prepared all necessary technical documents and project plans in support of an EPA Class VI carbon dioxide injection permit.  Project utilized advanced techniques to characterize the 5,000 feet deep cambrian carbonate reservoir.  Ion composition, molar ratios, biogeochemistry, and isotopic characterization, were used to estimate the competence of the caprock and hydraulic stratification within the injection zone. The biomass concentrations and microbial diversity information was used to validate geochemical findings.

X-Ray Diffraction and Spectral Gamma Ray Analyses (specifically Rhomma-Umma analysis) were utilized for mineralogical characterization of the injection and confining zones. This information was necessary to develop the reaction kinetics for conducting geochemical simulations to establish the sequestration capacity and changes in formation petrophysical properties such as permeability and porosity due to precipitation of minerals.  Helical computerized tomography scans were examined to inspect the texture of the rocks and to detect the presence of minute fractures.  The Nuclear Magnetic Resonance (NMR) and sonic logs were used collectively to estimate the matrix and vuggy porosities.

Conducted multiphase flow and transport simulations using STOMP software to predict the plume size and pressure front.  Carried out geomechanical (poro-elastic) simulations in order to predict land surface deformations in support of (InSAR) satellite based monitoring of pore pressures in the injection zone.  Developed analytical methodologies for predicting the likelihood of inducing earthquakes due to injection.

Worked with U.S. EPA to lower the financial assurance costs, and with re-insurers for obtaining financial coverage in a seismically active area. Established the project Testing and Monitoring Plan and Quality Assurance/Quality Control protocols.  Developed operating plan for safe and efficient injection in order to mitigate operational risks associated with earthquakes and caprock leakage.
