... Approximate Gradient (StoSAG) method and the iterative least-squares support regression (LSSVR) proxy method are employed and compared. The optimization (or design) variables could be any combination of the variables like CO 2 injection rate, production BHP, durations of the injection, soaking...

.... Additionally, we develop a novel non-intrusive proxy-based workflow, referred to as SPN (surface pipeline network), to solve the surface network optimization with high efficiency and robustness. Complex situations can be properly addressed including looped network with indeterminate flow directions. Flow...

... ("refrac") candidate selection. The intent of this methodology is to create a proxy for reservoir quality and effective fracture surface area. Our primary objectives were: • Introduce an integrated workflow using fracture modeling and RTA to understand diagnostic signatures (i.e., long-term linear flow...

It appeared that this may have been a natural fracture because of the extreme intensity of the hydrocarbons, 70% higher than the next highest peak...

... Carlo (NN-MCMC) algorithm in the proposed AHM workflow for shale reservoirs. The reason is that MCMC, one of AHM in the Bayesian statistics, has benefits of quantifying uncertainty without bias or being trapped in any local minima. Also, using MCMC with neural network (NN) as a proxy model unlocks...

... 1.0 Abstract This study investigates the validity of geochemical paleoredox proxies in mature organic-rich shales. Classically, Fe-S-C org ternary diagrams and C-S crossplots have been used to differentiate between oxic, dysoxic, and anoxic / euxinic conditions, but should be limited...

... for conducting this analysis has consisted on including a "proxy" stress calculation into reservoir simulators. The caveat, is the incapability of the "proxy" to fully capture the real stress variations, leading to even more uncertain conclusions and riskier decisions. To better capture geomechanical effects...

The chemostratigraphic results reveal that significant stratigraphic variations in %Al (clay proxy), %Mg (dolomite proxy), %S...

... the relationship between complex regional fault systems, and their collective impact on stress fields in a region. The outputs of this modeling workflow can be combined into proxies, and used to investigate areas of the model with stress fields more likely to be perturbed through high-volume injections.

... ambiguous based on GR profiles alone are able to be properly correlated by utilizing surfaces that are recognized within chemostratigraphic profiles. Certain elements act as proxies for local depositional and environmental conditions during sedimentation. The principal elements used in this study...

... that sedimentary nitrogen isotope (d 15 N) measurements can be reliable proxies for determining water column redox state during deposition, as well as for compartmentalization and post-depositional fluid migration during catagenesis. This paper summarizes our investigations into the use of d 15 N measurements...

.... History matching and Monte-Carlo analyses become long and tedious processes. In this paper, a series of efficient reduced-order numerical proxies is proposed to replace these detailed models: – For simple geometries, numerical SRV-bounded or trilinear models are used. These 1-D models are fast...
