Published: November 2024

Abstract
In this article, with a focus on improving the framework of seismic hazard assessment (SHA), we propose a link-up procedure between the neodeterministic seismic hazard assessment (NDSHA) and the widely adopted probabilistic seismic hazard assessment (PSHA). We discussed why NDSHA should be linked with PSHA if the former is to play a role in the framework of the existing multilevel fortification strategy against earthquake disasters. The link-up procedure was illustrated by a case study in which scenario earthquake (SE) was the bridge between the two SHAs. Some potential issues related to the proposed procedure, such as the determination of SE, modeling of finite-fault source, and synthesis method of broadband ground motion, were further discussed. The final result is a set of hazard maps with multiple parameters and multiple fortification levels, which is appropriate for application to the seismic design of engineering structures. The improved hazard map highlights the hazards from future large earthquakes near big cities.

Abstract
Field investigations have long been an important component of the scientific response to surface-faulting earthquakes. However, in light of advances in remote data and models, the question arises whether field-based observations of surface rupture remain useful for understanding rupture processes and seismic hazards. We approach this question using a field-based study of the central 2023 Mw 7.8 Pazarcık, Turkey (Türkiye), earthquake rupture, at the intersection of the east Anatolian fault (EAF) and Narlı fault. Our field observations include the surface rupture expression and extent of the central EAF and northernmost Narlı fault in generally forested and steep terrain and 68 measurements of left-lateral surface displacement. These data improve our understanding of the Pazarcık rupture complexity, resolve the surface geometry of the Narlı fault–EAF connection, and exhibit a clear (&gt;2 m) change in surface displacement across this intersection zone that confirms remote-based coseismic slip models. Our study shows that focusing field efforts in areas of obscured or low-resolution remote data can yield essential data for refining rupture extent, documenting perishable on-fault displacement, and improving postearthquake situational awareness. A comparison of similarly large-magnitude continental surface-rupturing earthquakes indicates that displacement uncertainties relate to a complex set of factors, including measurement methods, rupture complexity, and displacement magnitude. Our study validates the need for postearthquake field observations, which, when driven by clear motivating questions and knowledge of methodological strengths and limitations, provide high-resolution rupture data that complement remote-based models.

Heterogeneous long-term and seasonal brine evolution, and Artemia fecal pellet controls on Urmia Lake (NW Iran) salt-crust formation and mineralogy
Authors: Mohammadi Ali 
Published: November 2024

ABSTRACT
Urmia Lake resides as a substantial hypersaline lake characterized by notable fluctuations in water salinity, brine composition, and water level over long-term, annual, and seasonal intervals. Extremely rapid water elevation fall (&gt; 7 m) in the last three decades has caused the formation of a salt crust on the lake floor. A manmade stone causeway divided the lake into two relatively deeper northern parts with minimal water inputs and a shallower southern part with maximal river inflows. Restricted water flow through the narrow water passage of the causeway leads to complex salinity processes, brine evolution, and salt-crust formation in Urmia Lake. This research analyzes the ionic composition of lake-sediment and salt-crust pore water, the mineralogy of salt crusts, and the ionic composition of both surface and deep lake waters during both the wet and dry seasons of 2019. The findings indicate that the northern and southern parts of the lake undergo stratification during wet seasons due to significant freshwater input, whereas they become homogenized during dry seasons through progressive evaporative concentration and water mixing. The spatial and temporal variations in the lake brine type (primary Na-Mg-Cl) and ionic composition contribute to the formation of a halite salt crust (NaCl &gt; 97%) with heterogeneous mineralogy and thickness. In Urmia Lake, the variable thickness and mineralogy of the exposed marginal salt crust suggest rapid salt-crust reorganization by annual and seasonal deposition and dissolution processes. Conversely, the submerged central salt crust, with continuous thickening and constant mineralogy, remains unaffected by seasonal variations in brine type and dissolution processes. It is noteworthy to mention that Artemia (a brine shrimp) controls the mineralogy of the lake salt crust through the deposition of calcium and carbonate ions in the form of biochemical fecal pellets.

Abstract
The Najmah MFS (marine flooding surface), known for its abundant organic-rich clay (2-30% TOC), presents considerable potential as a reservoir for gas, condensate, and light oil. Nonetheless, geosteering poses challenges due to limited seismic resolution and stratigraphic uncertainties, resulting in lateral fluctuations in petrophysical properties and pay-zone thickness. With porosity levels ranging from 2-6% and permeability from 0.01-1.5 mD, the flow-control mechanism relies heavily on a natural fracture network.
A preliminary well model was constructed using data from existing offset wells to evaluate various well-placement techniques. Utilizing a combination of ultra-deep azimuthal resistivity mapping (UDAR) and gamma-ray imaging tools facilitated precise geosteering of the lateral section. The primary objectives were to maintain the well trajectory within the productive zone, anticipate and detect any anomalies in the formation while navigating sub-seismic faults, and enable swift adjustments to sudden changes in formation dip. Additionally, an ultrasonic high-resolution imaging (UHRI) tool was employed in the lateral section to analyze fractures, faults, and borehole geometry, aiming to optimize completion design and improve production efficiency.
The 6-in. lateral section remained within the designated target zone, maximizing exposure to the reservoir while traversing various geological formations, including faults, which were delineated in the resistivity inversions. Combining deep and short-range measurements ensured precise placement of the well within the target area. The resistivity inversion highlighted multiple strata on a larger scale, away from the wellbore, while the gamma-ray image contributed to more accurate steering. Additionally, the UHRI facilitated the refinement of completion design and advanced field development by identifying a total of 426 features, including 342 fractures, 22 faults, and 62 bedding planes. Integrating UDAR with UHRI not only enabled successful horizontal well placement but also supported optimization of the completion design, resulting in enhanced production capabilities from the well.
These findings have provided significant insights into improving future field development strategies and optimizing completion designs. The methodology is highly recommended for application in upcoming well profiles with similar characteristics, aiming to enhance field development in the unconventional Najmah Limestone reservoir of North Kuwait.

Abstract
Both laboratory tests and pilot wells have demonstrated the significant potential of CO2 as an enhanced oil recovery (EOR) medium. Due to the weak pressure conduction and mass transfer of the CO2-oil system, multiple zones are generated between the injection well and production well in ultra-low permeability reservoirs. This work aims to explore the characteristics of these multiple zones and the mechanisms of CO2-EOR by combining experimental results, core-scale analysis, and field-scale simulation.
Long-core CO2 displacement experiments were conducted under different miscibility pressures, with production gas assayed using gas chromatography. The core-scale simulation was aligned with the experimental results, defining four CO2 fronts to distinguish different zones based on pressure, interfacial tension, and CO2 concentration along the long core. The distribution of five zones was upscaled to the field-scale model after pilot well history matching. The final step involved evaluating the miscible zone range value, CO2 injection utilization factor, oil recovery, and CO2 storage efficiency during the CO2 injection process.
Results show that the boundary between the original oil zone and the oil transition zone exists at the CO2 component front, where the CO2 concentration is zero. Additionally, the location of the CO2 component front does not overlap with the contact interface of CO2-crude oil, meaning that the dissolution effect of CO2 in the oil transition zone results in the CO2 component front moving farther. Besides, when the formation pressure is higher than the minimum miscibility pressure (MMP), the distance between the CO2-effective phase front and the CO2-effective component front further expands as the pressure increases, enlarging the miscible zone range. The pressure accumulates around the injection well because of slow pressure conduction. When the average formation pressure reaches 1.1 MMP, the miscible zone range is enlarged by 2.7% higher than that of the near miscible flooding (0.92 MMP), leading to a higher rate of oil recovery by 8.6% and a utilization factor of CO2 by 0.14t/t.
It is for the first time that the range of five zones and the characteristics of four CO2 fronts migration is assessed, furnishing an in-depth understanding of the complicated mechanisms and phase behavior in CO2 EOR in the ultra-low permeability oil reservoir. This work contributes to providing significant information for designing an economic and environmental CO2 flooding strategy and is significant in the improvement of oil recovery and the reduction of CO2 emission.

Published: November 2024

Abstract
Low sweep efficiency during water injection besets the oil production from matured Malaysian fields undergoing waterflood operations. The water conformance issue might cause premature breakthrough in heterogeneous reservoir leading to low oil recovery. In this study, we described comprehensive experimental work to evaluate emulsion stabilized by Pickering particles as conformance control agent considering the reservoir characteristics in offshore Malaysian fields. The Pickering emulsion offers better stability in terms of resistance against mechanical and thermal changes during propagation under reservoir conditions compared to surfactant-based emulsions. In addition, emulsion due to its rheology in comparison to foam and gel have low pumping requirements with minimum chances of formation damage, providing better selective placement and ability to maneuver to deep levels of the reservoir under high temperature, salinity, and pressure conditions. In the case of conformance control applications, the particle-based emulsions provide better pore throat plugging in the high permeability thief zones mostly due to the better adsorption of Pickering particles on to the rock surface.
This study investigated an ecofriendly novel carbon nanocomposite-based Pickering emulsion designed for conformance control in harsh environments of high-temperature and salinity typical of reservoirs in Malaysian fields. The research evaluated the thermal stability, rheological behavior of the emulsion under different temperatures, and salinities. Adsorption behavior of the emulsion on sandstone rock surface was analyzed based on rock-fluid interaction via contact angle measurements. We performed core flooding test to evaluate plugging performance by determining permeability reduction stimulated by the emulsion closely mimicking reservoir conditions.
A permeability reduction of 98.2% was observed showing promising plugging performance with single pill injection and maintaining colloidal stability under dynamic conditions.
The insights from this study can be beneficial to optimize emulsion design during the development phase, leading to improved performance of the conformance control agent with the reservoir. Moreover, the newly developed, ecofriendly emulsion due to its low volume consumption and superior plugging performance can potentially enhance conformance control performance in Malaysian reservoirs by reduction excess water production and consumption, thereby reducing operational costs and increasing oil production from untapped low permeable zones.
Effects of soil saturation and suction on root reinforcement performance: pull-out experiments on six native Australian plants

Abstract

Improving shallow slope stability with vegetation requires an understanding of root reinforcement performance, in addition to consideration of local ecological impacts. Existing root reinforcement models have not accounted for the influence of soil water content, due to insufficient experimental evidence and theoretical understanding. In this study, the root reinforcement behaviour of six Australian native plants (A. costata, B. integrifolia, E. reticulatus, P. incisa, C. citrinus, and M. thymifolia) are examined through vertical pull-out tests under various levels of volumetric water content (VWC) and suction. Additionally, this study employed two root reinforcement models to illustrate the impact of VWC on comparing the performance of these models with experimental results. The study also employs an innovative approach by making an analogy to soil nails or piles and normalising pull-out force against the peripheral surface area of root-soil bundles, defining this as pull-out stress. The results show that VWC and suction have a strong influence on reinforcement, with an roughly linear inverse relationship observed between VWC and pull-out force of root bundles recorded for all species. The pull-out stress followed a non-linear inverse relationship with VWC and suction as the pull-out force. Furthermore, discrepancies between established-model predictions and experimental data widen with increasing VWCs. It is also found that inadequate sampling can also lead to substantial errors in estimating the actual water content of the soil. The study demonstrates that VWC and suction significantly impact root reinforcement performance, with pull-out strength decreasing as VWC increases. The study also highlights the importance of accurately recording soil water content in root reinforcement experiments and modelling.
Exogenous addition of methyl jasmonate and salicylic acid in immobilized cell cultures of Thevetia peruviana: Effect on the biomass, phenolic compounds and cardiac glycosides production

Published: November 2024

Abstract

Thevetia peruvianais an ornamental shrub with ethnobotanical uses related to secondary metabolites, including cardiac glycosides (CG), phenolic compounds (PC), and flavonoids (Fv). Known for its cardiac, antioxidant, anticancer, and antimicrobial activities, this study aimed to culture T. peruviana cells immobilized in calcium alginate and evaluate the effects of exogenous methyl jasmonate (MeJA) and salicylic acid (SA) on biomass and metabolite production. Immobilization was performed with 3% (w/v) sodium alginate and 100 mM CaCl₂ in Schenk and Hildebrandt medium. Cultures were maintained for 20 days, reaching a maximum biomass concentration of 7.45 ± 0.49 g/L on day 10, compared to 13.92 ± 0.34 g DW/L in free cell cultures. Immobilization reduced biomass concentration but increased the production of secondary metabolites at 10-11 days. This suggests that the alginate matrix acts as an abiotic stress factor, directing carbon consumption and energy flow toward the biosynthesis of PC, Fv, and CG. Additionally, treatment with SA (300 µM) and MeJA (3 µM) during the exponential phase increased metabolite secretion at 48-72 hours post-elicitation. SA-treated cultures showed PC, Fv, and CG levels 2.24, 1.66, and 1.37 times higher than controls, respectively, while MeJA increased these levels by 1.24, 1.83, and 1.25 times. Exogenous SA and MeJA stimulate the biosynthesis of secondary metabolites in calcium alginate-immobilized T. peruviana cells; and facilitate the diffusion of metabolites into the extracellular medium. However, further studies are needed to validate this hypothesis.
