Investigation on the effect of active-polymers with different functional groups for EOR

e-Polymers, 2020
Active-polymer attracted increasing interest as an enhancing oil recovery technology in oilfield development owing to the characteristics of polymer and surfactant. Different types of active functional groups, which grafted on the polymer branched chain,

Stability and Behavior of Bulk Nanobubbles Under Reservoir Conditions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Compared with microbubbles, nanobubbles exhibit superior stability, higher specific surface area, and smaller size. These characteristics have increasingly attracted the attention of petroleum researchers. However, existing literature lacks studies on nanobubble concentration and size under harsh reservoir conditions. To address this gap, this

Salinity Effect on the Surfactant Critical Micelle Concentration through Surface Tension Measurement [PDF]

Iranian Journal of Oil & Gas Science and Technology, 2019
One of the tertiary methods for enhanced oil recovery (EOR) is the injection of chemicals into oil reservoirs, and surface active agents (surfactants) are among the most used chemicals.

Study on Natural Gas Decarbonization Process Based on CO2 Desublimation Characteristics

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Natural gas decarbonization is a crucial processing step. In this study, the snow separation technology for removal of carbon dioxide in natural gas based on CO2 desublimation characteristics was introduced. The phase equilibrium calculation of CH4‐CO2 and N2‐CO2 system was carried out by using cubic equations of states (EOSs), and identified ...

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Thermal Energy Estimation by In-situ Combustion in An Abandoned Oil Well

Journal of Earth Energy Engineering, 2021
A downside of producing oil is that it can never be fully recovered. After the end of a well's life span, the residual oil remaining in the reservoir on average can be over 30%.

The paper puzzle as an active learning tool in the teaching of anatomy: A qualitative study of perceptions in students and near‐peer teachers

Anatomical Sciences Education, EarlyView.
Abstract Active learning strategies enhance medical education by fostering self‐directed learning, communication, and problem‐solving skills. The paper puzzle, a game‐based learning approach, provides an engaging way to reinforce anatomical knowledge and promote collaboration.

CO₂ dissolution-diffusion in clay inhibitor/oil systems and synergistic CCUS-EOR effects in strongly water-sensitive reservoirs

Scientific Reports
This study targeted a highly water-sensitive reservoir with high clay content (average 23.87%, mainly montmorillonite and illite), where waterflooding development induces hydration swelling of clay minerals, leading to pore-throat narrowing.
