Development and performance evaluation of foaming agent for heavy oil development and study on oil displacement mechanism in heterogeneous micromodel

open access: yesJournal of Petroleum Exploration and Production Technology
Due to their high viscoelasticity and excellent plugging ability, surfactant foam systems can mitigate the effects of heterogeneity and have emerged as a key technology in tertiary oil recovery in recent years.

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Standard methods and related techniques for on-line detection of the total sulfur content in natural gas

open access: yesNatural Gas Industry B, 2018
At present, many domestic total sulfur detection methods are accurate and reliable, but they are disadvantageous with a low detection frequency, a long detection period and delayed work.

Strategic Eurasian Natural Gas Model for Energy Security [PDF]

open access: yes, 2011
The mathematical formulation of a large-scale equilibrium natural gas simulation model is presented. Although large-scale natural gas models have been developed and used for energy security and policy analysis quite extensively (e.g., Holz (2007), Egging

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Cross-flow area recognition in fractured oil reservoirs and foam flow characteristics

open access: yesJournal of Petroleum Exploration and Production Technology
Fracture-cavity reservoirs are prone to frequent channeling pathways during foam flooding due to their complex fracture networks, which severely restricts the enhancement of oil recovery and CO₂ storage efficiency.

The World Gas Market in 2030: Development Scenarios Using the World Gas Model [PDF]

open access: yes
In this paper, we discuss potential developments of the world natural gas industry at the horizon of 2030. We use the World Gas Model (WGM), a dynamic, strategic representation of world natural gas production, trade, and consumption between 2005 and 2030.

A bridge to a low carbon future? Modelling the long-term global potential of natural gas [PDF]

open access: yes, 2014
This project uses the global TIMES Integrated Assessment Model in UCL (‘TIAM-UCL’) to provide robust quantitative insights into the future of natural gas in the energy system and in particular whether or not gas has the potential to act as a ‘bridge’ to ...
