Finite difference schemes for the symmetric Keyfitz-Kranzer system

, 2012
We are concerned with the convergence of numerical schemes for the initial value problem associated to the Keyfitz-Kranzer system of equations. This system is a toy model for several important models such as in elasticity theory, magnetohydrodynamics ...

Biomimetic Ion‐Orchestrated Hierarchical Armored Hydrogel Coating for Robust and Multifunctional Surface Protection

Advanced Functional Materials, EarlyView.
Inspired by the skin‐toughening mechanism of marine sponges, an ion‐orchestrated structural engineering strategy is proposed to regulate the surface microstructure of hydrogel coatings, enabling the in situ formation of a robust armor layer that enhances mechanical integrity and provides multifunctional protection by suppressing fouling attachment and ...

New technologies of enhanced oil recovery [PDF]

, 2006
It is known from the literature that up to 27 % of oil in oilfields can be produced using primary and hydration methods. The efficiency of production can be increased by employing more advanced methods, i.e. EOR. The Polish Oil and Gas Company iwork with

Charge Transport in Ternary Charge‐Transfer Solid Solution Single Crystals

Advanced Functional Materials, EarlyView.
This study deconvolutes the roles of indirect (superexchange) and direct electronic coupling on charge transport in single crystals of an organic charge‐transfer molecular semiconductor (OSC). This model system elegantly demonstrates that structural defects introduced by chemical dopants play a significant role in the electronic performance ...

Laboratory Experiments on Enhanced Oil Recovery with Nitrogen Injection [PDF]

, 2007
Based on previous studies, nitrogen injection could recover oil up to 45-90% of initial reserves. Although this method has a very good ability to produce oil, sometimes the operation pressure is higher than leak off formation pressure.

Proteins, Processing, and Properties of Adhesive Fluid Condensates Purified from Mussels

Advanced Functional Materials, EarlyView.
Mussels exhibit an unmatched proficiency for adhering to wet surfaces in salty environments—a remarkable ability that could inspire new biomedical and technical glues. The fluid protein condensates used to form the underwater mussel glue are extracted, reconstituted and characterized with advanced spectroscopy and nanomechanical analysis, revealing ...

Water Shutoff with Polymer Gels in a High-Temperature Gas Reservoir in China: A Success Story

Energies
Gel treatments have been widely applied to control water production in oil and gas reservoirs. However, for water shutoff in dense gas reservoirs, most gel-based treatments focus on individual wells rather than the entire reservoir, exhibiting limited ...

Distribution Of Co2 In Fractured Carbonate Reservoirs [PDF]

, 2017
Deep geologic injection of supercritical carbon dioxide (CO2) for enhanced oil recovery (EOR) has been widely used for improved oil recovery from depleted oilfields since early 1970s. The CO2 injection maintains the pressure, mobilize the oil and release

Chemical Enhanced Oil Recovery

International Journal for Innovation Education and Research, 2021
Enhanced Oil Recovery (EOR) techniques are currently one of the top priorities of technological development in the oil industry owing to the increasing demand for oil and gas, which cannot be fulfilled by primary or secondary production methods. The main function of the enhanced oil recovery process is to displace oil in the production wells by the ...
