Reservoir Model Optimization Using the Seismic Response to CO 2 Injection and Stochastic Inversion Abelardo L. Ramirez 1 , Kathy Dyer 1 , Donald J. White 2 , Yue Hao 1 , James Johnson 3 1-Lawrence Livermore National Laboratory 2-Geological Survey of Canada 3-Schlumberger-Doll Research Center...

Leakage of CO 2 and brine through pre-existing wellbores is considered to be one of the main potential risks at geologic CO 2 sequestration sites. To assess impacts of this potential weakness, it is critical to accurately estimate leakage rates through failed wellbores. Currently, there is very...

The photochemical reduction of CO 2 in the presence of H 2 O to form CO, CH 4 and other light gases with industrial value is an interesting approach for dealing with CO 2 emissions. This approach can generate tangible revenue to help offset carbon capture and storage costs by generating a product...

This study conducted quantitative kinetic modeling and in-situ and temporally resolved measurements of adsorption, desorption, and re-adsorption of a commercial endoglucanase in lignocellulosic suspensions. The study defined a cellulase adsorption and desorption competition parameter, a pseudo rate...

Ceramic proppant was imaged using x-ray computed microtomography (microCT) in three different geometries: bulk proppant, multilayer proppant pack between Berea walls, and single-layer proppant between shale walls. In all cases, the proppant packs were exposed to a range of confining stresses that...

Hot Melt Extrusion: Identification and optimization of key excipients utilizing high-throughput screening methodology. By utilizing various tool kits available in the chemical engineering toolbox, a case study would be presented on formulation development in an accelerate timeframe for a marketed...

With large proven global coal reserves, it is highly likely that combustion of coal and coal-derived products will remain part of the global energy future. Compared to other fossil fuels, coal-based power yields the highest CO 2 output per energy unit, indicating the critical need for some form of...

A recently-developed lubrication blending model identified formulation-dependent parameters for lubrication sensitivity, β, and lubrication rate constant, γ. The original study examined binary mixtures of common tableting excipients. Therefore, there is a need to determine if the lubrication model...

Thermocatalytic conversion of carbon dioxide to methanol has recently gained considerable attention because it is regarded as an optimal solution to mitigate CO 2 emissions while generating revenues to offset carbon management costs. Currently, commercial synthesis of methanol is accomplished by...

Control of the flow properties of powders during one or more unit operations of a manufacturing process is an essential part of ensuring that the process is well-controlled. It is commonplace to incorporate flow-modifying agents to match the flow properties of the powder to those required by the...
