The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

ENABLING PARTIAL UPGRADING IN ALBERTA: A REVIEW OF THE REGULATORY FRAMEWORK AND OPPORTUNITIES FOR IMPROVEMENT

The School of Public Policy Publications, 2019
One of the ways that Alberta can help alleviate its worsening bottleneck in oilexport pipelines is by partially upgrading oil sands bitumen before shipping it to market.

Influence of rejuvenators on bitumen ageing in hot recycled asphalt mixtures

Journal of Traffic and Transportation Engineering (English ed. Online), 2018
The use of reclaimed asphalt pavement (RAP) in new hot mix asphalt (HMA) by means of hot recycling techniques generates the advantage linked to the exploitation of both lytic and bituminous component, consequently leading to the decrease of both virgin ...

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4787-4808, September 2026.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

Exploratory study on bitumen content determination for foamed bitumen mixes based on porosity and indirect tensile strength

Journal of Traffic and Transportation Engineering (English ed. Online), 2017
Optimum bitumen content determination is one of the major aims for foamed bitumen mix design. However, mix design procedures for foamed bitumen mixes are still under development.

Effect of SBS Copolymer Molecular Structure on the Long‐Term Aging and Resilience of Asphalt Binders: A Multiscale Morphological Study

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Vinyl content governs the long‐term ageing resistance of SBS‐modified bitumen. Multiscale AFM, FM, SEM, and FTIR analyses show that low‐vinyl SBS copolymers (L‐SBS, B‐SBS) undergo pronounced bee‐phase growth, stiffening, and network fragmentation after PAV ageing, whereas high‐vinyl variants (HV‐SBS, DB‐SB) retain their morphology and chemistry ...

Molecular investigation of the phylogenetic placement of Kartalinia and a revision of Bituminaria (Fabaceae: Psoraleeae)

TAXON, Volume 75, Issue 4, August 2026.
Abstract The genus Kartalinia was described to accommodate a single, obscure species, Psoralea acaulis, based on its unique morphology and karyology. No concerted molecular phylogenetic studies were available for this species at the time, and therefore its phylogenetic position was uncertain.

Carbonate‐Associated Sulfate Does Not Record Superheavy δ34S in Deep Scandinavian Bedrock Fractures: Implications for Pyrite Formation in the Deep Biosphere

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract In deep bedrock fractures of the Fennoscandian shield, pyrite with “superheavy” δ34S values of up to 147‰ exists together with calcite. The extreme variability and 34S‐enrichment in pyrite indicate that microbial sulfate reduction (MSR) evolved to almost complete sulfate exhaustion in closed‐system microenvironments.
