A Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs

open access: yesJournal of Surfactants and Detergents, EarlyView.
The Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs. ABSTRACT Surfactants with both positive and negative functional groups (amphoteric or zwitterionic) are particularly advantageous in acidic oil reservoirs because they remain stable under harsh chemical conditions, tolerate acidic ...

Characteristics of viscosity-reducer foam flooding in deep low-permeability heavy oil reservoirs

open access: yesYouqi dizhi yu caishoulu
Viscosity-reducer foam flooding combines the advantages of emulsification of viscosity-reducers and selective blocking of foam to further enhance oil recovery in deep low-permeability heavy oil reservoirs during the later development stages. The suitable

Fixing Ill‐Formed UTF‐16 Strings With SIMD Instructions

open access: yesSoftware: Practice and Experience, EarlyView.
ABSTRACT Background We must fix ill‐formed UTF‐16 strings, where surrogate pairs are mismatched. Programming languages such as JavaScript provide functions that replace mismatched surrogates with the Unicode replacement character (U + FFFD). Objectives We seek to accelerate the correction of ill‐formed UTF‐16 strings.

Application of Intelligent Systems in CO2 Management: State of the Art and Future Prospects

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Machine learning (ML) integration is becoming increasingly popular in advancing the 4th industrial revolution, known as Industry 4.0. This review paper examines ML applications in CO2 management stages: emission, capture, and conversion. ML models, including multiple linear regression (MLR), multiple nonlinear regression (MNLR), and artificial

Quantifying the impact of surface roughness on contact angle dynamics under varying conditions

open access: yesScientific Reports
Despite extensive research in recent years to clarify the role of fluid composition on reservoir wettability, understanding the properties of rock and its solid surface characteristics and their effects on wettability and its alteration remains limited ...

Cross-cultural study of intensifiers in face-threatening situations: A gender perspective in English and Bahasa Indonesia [PDF]

open access: yesTraining, Language and Culture
Intensifiers play a crucial role in everyday communication, varying in frequency, function, and socio-pragmatic significance across languages. However, gender-based variation in their use remains underexplored. This study examines intensifier usage among

The role of polar organic components in dynamic crude oil adsorption on sandstones and carbonates

open access: yesCT&F Ciencia, Tecnología & Futuro, 2020
An appropriated wettability characterization is crucial for the successful implementation of waterflooding operations. Understanding how crude oil adsorption takes place on different mineral surfaces and how these processes impact reservoir wettability ...

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

open access: yesComputer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...
