Complementary Workflows for Analyzing Multiphase Flowback and Post-flowback Production Data In Unconventional Reservoirs
DownloadFall 2017
The application of horizontal drilling and hydraulic fracturing techniques has resulted in the economic production of previously inaccessible hydrocarbon trapped in very-low permeability reservoirs such as Shale gas/oil, tight gas and tight oil. Although the economic production of these...

Osteoporosis is currently the most common metabolic musculoskeletal disease which causes brittle bones with a consequent increase in bone fragility and susceptibility to fracture. This “silent epidemic” is mainly characterized by the loss of bone mass, micro-structural deterioration, and cortical...

Full waveform inversion using simultaneous encoded sources based on first- and second-order optimization methods
DownloadFall 2014
Full waveform inversion (FWI) is an emerging seismic technology engine for estimating subsurface model parameters such as velocity, density and attenuation through local minimization of an objective function. The minimization problem is often performed iteratively via gradient-based method that...

Many geophysical inverse problems are ill-posed and have to be regularized. The most often used solution methods for solving ill-posed problems are based on the use of quadratic regularization that results in smooth solutions. Solutions of this type are not to be suitable when the model parameter...
