Sustainability of a Rainfed Wheat Production System in Relation to Water and Nitrogen Dynamics in the Soil
Authors: Phogat V. , Šimůnek J. , Petrie P. , Pitt T. , Filipović Vilim
Published: August 2023

Nitrogen (N) applications can play a key role in achieving profitable wheat production in the low-fertility soils prevalent under rainfed conditions. The model-predicted N partitioning revealed that ammonia-nitrogen (NH4-N) contributed little to the plant N nutrition, and its concentration in the soil remained below 2 ppm throughout the crop season except immediately after the NH4-N based fertilizer application. Nitrate-nitrogen (NO3-N) gradually increased (maximum 144 ppm) with time, especially in the 0-40 cm horizons, and contributed to most N uptake during both seasons at both locations. The N losses from the soil at the medium rainfall site (3.5-20.5 kg ha-1) were mainly attributed to NH4-N volatilization (Nv) and NO3-N leaching (NL) below the crop root zone. Water productivity (8-40 kg ha-1 mm-1) and N use efficiency (31-41 kg kg-1) showed immense variability induced by climate, water availability, and N dynamics in the soil. These results suggest that combining water balance and N modeling can help manage N applications to optimize wheat production and minimize N losses in rainfed agriculture.
Babul Bark Extraction as Green Corrosion Inhibitor for Brass in Acidic solution: A Voltammetric Approach
Authors: Patel Shakuntal , Mishra Jyotsna
Published: August 2023

The Voltammetric and polarographic methods are proposed to determine the short time corro-sion rates of brass in 1N HCl solution. It should be noted that it is also possible to determine the corrosion rates of each species present in the solution, simultaneously like Cu (II) and Zn (II) in brass. Samples extracted from bark of Babul (ESBB) is used as corrosion inhibitors. The corrosion inhibition efficiency is 96% at 24h after the test started. These results are compared with the av-erage corrosion rates obtained by using gravimetric (PIT) and some electrochemical methods i.e. galvanostatic and potentiodynamic polarization measurements.
High Sensitivity for Detection of Primary Diagnostic Variants in Autism, Including De Novo Variants, with Trio Whole Genome Sequencing and Data Reanalysis
Authors: Bar Omri , Vahey Elizabeth , Mintz Mark , Frye Richard E. , Boles Richard G.
Published: August 2023

Autism spectrum disorder (ASD) is a common condition with lifelong implications and a strong hereditary component suggesting genetic underpinnings. The last decade has seen dramatic improvements in DNA sequencing, bioinformatics, and databases.

We analyzed the raw DNA sequencing files on the Variantyx® (Framingham, MA, USA) bioinformatics platform for the last 50 autism patients evaluated with trio whole genome sequencing (trio-WGS). “Qualified” variants were defined as coding, very rare, and evolutionarily conserved. Primary Diagnostic Variants (PDV) additionally were in genes directly linked to ASD.

A PDV was identified in 34/50 (68%) of cases, including 25 (50%) heterozygous de novo, 3 X-linked, 4 autosomal recessive, 2 autosomal dominant, and 1 heteroplasmic mtDNA variants. De novo variants in genes associated with ASD were far more likely to be Qualified than non-Qualified (control group, P = 0.002), validating that most are indeed disease causal. Only 14/34 (41%) of PDV cases had the variant listed on the laboratory report, and reanalysis increased diagnostic yield from 28% to 68%. The “missed” cases predominately included genes with zero (14 cases) to ≤5 prior reported case reports. Many cases both with and without a PDV had inherited Qualifying variants in known ASD-associated genes, suggesting polygenic inheritance. Thirty-three participants (66%) had treatment recommendation(s) based on DNA analyses.

Our results demonstrate high yield of trio-WGS for revealing molecular diagnoses in ASD that is greatly enhanced by re-analyzing DNA sequencing files. Many are de novo and represent un/under-published conditions.

Authors: Matsufuji Yasuyo , Ueji Kayoko , Yamamoto Takashi
Published: August 2023

Previous studies have indicated that facial expressions can serve as an objective evaluation method for hedonics (overall pleasure) of food and beverages. In this study, we aimed to validate the findings of our previous research, which demonstrated that facial expressions induced by tastants can predict the perceived hedonic ratings of these tastants. Facial expressions of 29 female participants (aged 18-55 years) were recorded using a digital camera while they consumed 12 different concentrations of solutions representing five basic tastes. The facial expressions were then analyzed using the widely-used facial expression analysis application, FaceReader, to identify seven emotions (surprise, happiness, scare, neutral, disgust, sadness, and anger) with scores ranging from 0 to 1. Participants also rated the hedonics of each solution on a scale from -5 (extremely unpleasant) to +5 (extremely pleasant). A multiple linear regression analysis was conducted to develop a formula to predict perceived hedonic ratings. The formula's applicability was tested by analyzing emotion scores for 11 additional taste solutions consumed by 20 other participants. The predicted hedonic ratings demonstrated good correlation and concordance with the perceived ratings, supporting the validity of our previous findings using different software and taste stimuli among diverse participants.
Retrovirus-Derived RTL/SIRH Genes: Their Diverse Roles in the Current Eutherian Developmental System and Contribution to Eutherian Evolution
Authors: Kaneko-Ishino Tomoko , Ishino Fumitoshi
Published: August 2023

Eutherians have 11 retrotransposon Gag-like (RTL)/sushi-ichi retrotransposon homolog (SIRH) genes presumably derived from a certain retrovirus. Accumulating evidence indicates that the RTL/SIRH genes play a variety of roles in the current mammalian developmental system, such as in the placenta, brain and innate immune system in a eutherian-specific manner. It has been shown that the functional role of Paternally Expressed 10 (PEG10) in placental formation is unique to the therian mammals, as are the eutherian-specific roles of PEG10 and PEG11/RTL1 in maintaining the fetal capillary network and the endocrine regulation of RTL7/SIRH7 (aka Leucine Zipper Down-Regulated in Cancer 1 (LDOCK1)) in the placenta. In the brain, PEG11/RTL1 is expressed in the corticospinal tract and hippocampal commissure, mammalian-specific structures, and in the corpus callosum, a eutherian-specific structure. Unexpectedly, at least three RTL/SIRH genes, RTL5/SIRH8, RTL6/SIRH3 and RTL9/SIRH10, play important roles in combating a variety of pathogens, viruses, bacteria and fungi, respectively, suggesting that the innate immunity system of the brain in eutherians has been enhanced by the emergence of these new components. In this review, we will summarize the function of 10 out of the 11 RTL/SIRH genes and discuss their roles in eutherian development and evolution.
Role of Substance P and Neurokinin-1 Receptor System in Thyroid Cancer: New Targets for Cancer Treatment
Authors: Isorna Inmaculada , Gonzalez-Moles Miguel Angel , Muñoz Miguel , Esteban Francisco
Published: August 2023

In recent years, numerous approaches have been developed to comprehend the molecular altera-tions underlying thyroid cancer (TC) oncogenesis and explore novel therapeutic strategies for TC. It is now well established that the neurokinin-1 receptor (NK-1R) is overexpressed in cancer cells and that NK-1R is essential for viability of cancer cells. The binding of substance P (SP) to NK-1R in neoplastic cells plays a pivotal role in cancer progression by promoting neoplastic cell growth, protecting tumour cells from apoptosis, triggering invasion and metastasis through enhanced migration of cancer cells, and stimulating endothelial cell proliferation for tumour angiogenesis. Remarkably, all types of human TC (papillary, follicular, medullary, anaplastic), as well as met-astatic lesions, exhibit overexpression of SP and NK-1R compared to the normal thyroid gland. TC cells synthesize and release SP, which exerts its multiple functions through autocrine, para-crine, intracrine, and neuroendocrine processes, including the regulation of tumour burden. Con-sequently, the secretion of SP from TC results in increased SP levels in plasma, which are signifi-cantly higher in TC patients compared to controls. Additionally, NK-1R antagonists have demonstrated a dose-dependent antitumour action. They impair cancer cell proliferation on one side and induce apoptosis of tumour cells on the other side. Furthermore, it has been demonstrat-ed that NK-1R antagonists inhibit neoplastic cell migration, thereby impairing both invasiveness and metastatic abilities, as well as angiogenesis. Given the consistent overexpression of NK-1R in all types of TC, targeting this receptor represents a promising therapeutic approach for TC. Therefore, NK-1R antagonists, such as the drug aprepitant, may represent novel drugs for TC treatment.

Published: August 2023

To date, recanalization interventions are the only available treatments for ischemic stroke patients, however, there are no effective therapies for reducing stroke-induced neuroinflammation. We recently reported that H+ extrusion protein Na+/H+ exchanger-1 (NHE1) plays an important role in stroke-induced inflammation and white matter injury. In this study, we tested the efficacy of two potent NHE1 inhibitors, HOE642 and Rimeporide, with a delayed administration regimen starting at 24 h post-stroke in adult C57BL/6J mice. Post-stroke HOE642 and Rimeporide treatments accelerated motor and cognitive function recovery without affecting the initial ischemic infarct, neuronal damage or reactive astrogliosis. However, delayed administration of NHE1 blockers after ischemic stroke significantly reduced microglial inflammatory activation while enhanced oligodendrogenesis and white matter myelination, with increased proliferation and decreased apoptosis of the oligodendrocytes. Our findings suggest that NHE1 protein plays an important role in microglia-mediated inflammation and white matter damage. Pharmacological blockade of NHE1 protein activity reduced microglia inflammatory responses and enhanced oligodendrogenesis and white matter repair, leading to motor and cognitive function recovery after stroke. Our study reveals the potential of targeting NHE1 protein as therapeutic strategy for ischemic stroke therapy.
Does Living Near Public Transport Equate to Food (In)security in the United States? – Evidence from the 2020 National Health Interview Survey (NHIS)
Authors: Chandra Shailesh , Naik R. Thirumaleswara , Torres-Aguilera Jose
Published: August 2023

Food security is intrinsically related to health and well-being. This paper investigates the status-quo of food insecurity among the population residing close to transit in various parts of the United States of America (USA). The data from the 2020 National Health Interview Survey (NHIS) collected by the National Center for Health Statistics (NCHS) of the USA are analyzed in this research. Logistic regression is carried out by treating food insecurity as the dependent variable and socioeconomic variables such as age, income, education and dependency on the Supplemental Nutrition Assistance Program (SNAP) as independent variables. Food insecurity is assessed with aggregated information on four aspects of inputs from those respondents who live near a transit: 1) worry food would run out, 2) food didn't last, 3) couldn't afford to eat balanced meals, and 4) cut the size of meals or skip meals. Findings suggest that respondents who live close to transit in the USA and are from large central metro counties of the Northeast, Southern and Western states showed an increase in food insecurity if they were below 65 years of age, had income below country’s median income or their educational attainment was below bachelor’s degree. There was a significant association found between food insecurity of respondents living close to transit and subscribed to using food stamps or SNAP. Policies that could alleviate food insecurity by reducing cost of living near transit are recommended.
A New CNN-based Single-Ingredient Classification Model and Its Application in Food Image Segmentation
Authors: Zhu Ziyi , Dai Ying
Published: August 2023

It is important for food recognition to separate each ingredient within a food image at the pixel level. In this paper, we propose a new approach to segment ingredients by utilizing a CNN-based Single-Ingredient Classification Model. In detail, we firstly introduce a standardized biological-based hierarchical ingredient structure and construct a single-ingredient image dataset based on this structure. Then, we build a single-ingredient classification model based on a novel convolutional neural network (CNN) architecture that utilizes an attention mechanism. Afterwards, we propose a new framework for segmentation using the above single-ingredient classification model as the backbone. In this framework, two methods are involved in segmenting ingredients in the food images. We introduce five evaluation metrics (IoU, Dice, Purity, Entirety, Loss of GTs) to assess the performance of ingredient segmentation in terms of ingredient classification. Extensive experiments demonstrate the effectiveness of the proposed method, achieving an maximal mIoU of 0.65, mDice of 0.77, mPurity of 0.83, mEntirety of 0.80, and mLoGTs of 0.06 on the FoodSeg103 dataset. The results confirm that our CNN-based architecture achieves higher segmentation performance compared to ResNet18 and EfficientNet-B0 when used as the backbone for ingredient segmentation. We believe that our ingredient segmentation approach lays the foundation for subsequent ingredient recognition.

Nerve Structure-Function. Unusual Structural Details and Unmasking of Sulfhydryl Groups by Electrical Stimulation or Asphyxia in Axon Membranes and Gap Junctions
Authors: Peracchia Camillo
Published: August 2023

This review describes and discusses unusual axonal structural details and evidence for unmasking of sulfhydryl groups (-SH) in axoplasmic membranes resulting from electrical stimulation or asphyxia. Crayfish axons contain fenestrated septa (FS) that in phase contrast micrographs appear as repeated striations. In the electron microscope each septum is made of two cross-sectioned membranes containing ~550 Å pores, each occupied by a microtubule. Thin filaments, likely to be made of kinesin, bridge the microtubule to the edge of the pore. FS are believed to play a role in axoplasmic flow. The axons also display areas in which axon and sheath-glial cell plasma membranes are sharply curved and project into the axoplasm. In freeze-fractures, the protoplasmic leaflet (P-face) of the projections appears as elongated indentations containing parallel chains of particles. The sheath-glial cell plasma membrane also contains particles, but they are irregularly aggregated. The axons also display areas where axonal and glial plasma membranes fuse, creating intercellular pores. In axons fixed during electrical stimulation the plasma membrane, the outer membrane of mitochondria, membranes of other cytoplasmic organelles and gap junctions increase in electron opacity and thickness, resulting from unmasking of sulfhydryl groups (-SH). Similar changes occur in asphyxiated nerve cords.

The prevalence of endometriosis is still high and amounts to 10% of women of reproductive age in the population; unfortunately, there is a continuing negative trend towards its increase. Early reproductive losses in endometriosis contribute to the risk of several subsequent obstetric and gynecological complications. The presence of post-traumatic syndrome and some other psycho-emotional disorders in the patients of this cohort demonstrates the need for a thorough and efficient rehabilitation. One of the most effective means of rehabilitation in the post-abortion period, in addition to psychological correction, are dienogestcontaining combined oral contraceptives, which provide a woman with reliable contraception, improve the recovery process before planning next pregnancy, and preserve a reproductive potential. Key words: endometriosis, reproductive loss, abortion, contraception

Published: August 2023

Public sector challenges tend to be translated into more complex job demands which require individual innovation. To deal with the demands, many public organizations implement employee performance management. The current study analyzes the key determinants of employee performance to find a new model as a reference for Islamic banking practitioners, especially in Indonesia. Data were collected by using a questionnaire, developed with Google Forms and disseminated via online social media. It employed accidental sampling technique upon 7 Islamic banks in Indonesia, by distributing questionnaires that followed a six-point Likert scale. Questionnaires were distributed to 356 employees through representatives of Islamic Banks, WhatsApp Group and LinkedIn, by which 350 respondents submitted. Thereupon, the data were tested using Structural Equation Modeling (SEM) Amos 25.0, which resulted in the finding that Work Motivation did not affect Employee Performance, and training also did not affect Employee performance. However, training significantly and positively affected cohesion with the highest path, and cohesion also affected employee performance. This study found that the main effect of employee performance is cohesion, which affirmed the research results of Appelbaum et al. (2020), Williams et al. (2016), and Kearnes (2020). The weakness of this study lied in the sample population which might be inhomogeneous because the research subjects have different organizational cultures. The study results served as a reference model for Islamic Banking directors in improving employee and banking performance, so they concern on the training factor without ignorance over the cohesion factor.

Be a Good Geoscientist First, and the Rest Will Follow
Authors: Roth B. L. , Hills D. J.
Published: August 2023

This paper seeks to demonstrate the application of learnings from the oil and gas industry, specifically in the field of geoscience, as they relate to applications within the growing industry of Carbon Capture, Utilization and Storage (CCUS). Additionally, this paper will highlight how current educational programs are already geared to produce a talent pipeline for young professionals beginning their careers in the CCUS field or for later career professionals who are looking to transition into CCUS.

To demonstrate the stated objectives, the fundamental theories and knowledge required to operate as a successful geoscientist in the oil and gas industry will be presented. This will include a discussion of basic skills and working knowledge as well as an introduction to various software utilized extensively within the oil and gas industry. This provides context illustrating where the geoscience community has been and the prior focus of many geoscience education pipelines. Then, a comparison of the oil and gas workflows to CCUS workflows will be made to demonstrate that the skills and techniques are aligned.

Example workflows from our experience developing CCUS projects will be presented with a focus on the geologic characterization, such as generating subsurface geologic and structural models and developing reservoir models to predict plume migration. It will be made clear that the fundamentals of these workflows and the skills necessary to implement them are essentially the same. Both oil and gas and CCUS workflows utilize the same basic knowledge and geologic understanding (e.g., reservoir porosity, permeability, volumetrics), the same data (e.g., geophysical well logs, seismic reflection surveys, geologic core analysis) and even the same software. This demonstrates the direct application of knowledge and workflows that were previously gatekept by the oil and gas community and highlights their significance in ability to be applied to new opportunities.

The discussion presented in this paper clearly identifies the overlap of experience gained throughout the detailed history of oil and gas exploration and its direct application to the burgeoning world of CCUS from the perspective of geologic characterization. The examples provided herein also demonstrate that the pipeline for creating new talent already exists with emphasis on learning the fundamentals of geoscience, and the specific application of those skills can be enacted seamlessly within the CCUS community.

Published: August 2023

A framework for evaluation of carbon offsetting strategies is presented depicting the journey of a large independent upstream exploration and production company towards making a first investment in the space. The framework for evaluation included three pillars: foundational and macro research of voluntary carbon markets, corporate intelligence, and project evaluation from a quality and strategic fit approach. Data examined included third party research data, public information from registries and other actors in the voluntary carbon market, and publicly available corporate publications. The information was also put into context against future decarbonization and company values to ultimately arrive at a strategy which was successfully deployed in a first-of-a-kind long-term carbon offset agreement with the Government of Guyana. Key observations made during the process were: 1) nature-based carbon offset projects provide a useful and necessary tool for global decarbonization towards a net-zero 2050 by providing private capital to developing nations, filling a gap from public pledges, while protecting important carbon sinks and ecosystems, 2) for independent E&Ps a strategy to secure offsets from high-quality, geographically-relevant, and large-scale projects appears to be optimal, and 3) demand for credits within the voluntary carbon market are likely to grow and reach around 1 billion tonnes per year by 2030 and potentially greater than 5 billion tonnes per year by 2050, outstripping the supply of high-quality credits. The voluntary carbon market is in its infancy. Excluding European majors, oil and gas companies are in the early stages of participating in the market with limited information published on the topic. This paper will present one approach for entering the market.
CO2 Leak Detection and Conformance Verification Using Borehole Gravity
Authors: Walker K. , Garcia A. Posenato , Nunn J. , Lyman G.
Published: August 2023

Borehole gravity measured from a vertical Carbon Capture and Storage (CCS) injection well, or nearby observation well, provides a cost-efficient solution for monitoring the reservoir for CO2 flow and the overburden for leaks. In this paper, two CO2 injection reservoir models using piston flow and Buckley-Leveret theory are built to simulate and evaluate surface and borehole gravity signatures associated with CO2 flow through thin and thick reservoirs in deep and shallow scenarios. The sensitivity of gravity to plume parameters is also analyzed. The results demonstrate that the lateral gradient in vertical surface gravity after a year of injection is effective for monitoring shallow reservoirs over relatively long time periods and ineffective for deep reservoirs. However, borehole gravity after only a few months of injection is sensitive to both time-lapse density variations and the lateral extent of the saturation plume in all reservoir thickness and depth scenarios. A competition exists for the dominant parameter controlling the borehole gravity signal between density contrast and plume radius. At the bottom of the borehole above the reservoir, sensitivity is dominated by density contrast. As one ascends the borehole, the distance to the reservoir below increases, which lowers the gravity while increasingly adding contributions to the vertical component of gravity, resulting in the plume radius becoming the most sensitive parameter. It is shown that this enhanced sensitivity enables inversions of borehole gravity, using weighted damped least squares, to sufficiently image the radial variation in density contrast associated with the CO2 plume. Analysis of survey parameters on inversion accuracy shows the benefit of conducting surveys that penetrate the reservoir. The results also show that while surface gravity is not capable of seeing small leaks, borehole gravity can detect the depth of leaks within hundreds of feet from a wellbore by a distinctive cross over along the gravity profile. The estimated plume radius based on a reservoir filling model and the comparison of that predicted smooth gravity profile to the observed profile that is sensitive to leak cross-overs in the confining zone provides a cost-effective measurement that can trigger higher cost surveys for deeper levels of investigation.

Published: August 2023

Low temperature geothermal resources, ranging from 80° to 120°C, may substantially lower both the cost and the CO2 emissions footprint of CO2 direct air capture (DAC) systems. This paper provides a model for determining a region-specific economic analysis for DAC with solid sorbent (S-DAC) using geothermal resources (S-DAC-GT).

This paper provides a model for calculating estimated cost and carbon emissions for potential S-DAC facilities on a region-specific basis. The paper outlines the necessary region-specific characteristics required as parameters for the techno-economic model. The region-specific characteristics are then applied to an S-DAC energy and cost model based on existing literature to calculate the levelized cost per tonne of CO2 captured and stored. Further, the model provides a reasonable approximation of the carbon intensity of the S-DAC-GT system. These calculations allow selecting and prioritizing regions appropriate for potential S-DAC-GT facilities operating at a scale of ~1 Mt CO2 captured and stored per year.

Existing DAC techno-economic analyses are region agnostic and do not account for geothermal energy as the primary thermal energy source. The novelty of this paper is its deeper technical and economic analysis using geothermal energy as the thermal resource for the S-DAC process. This paper provides a model for customization of the techno-economic model specific to the target region. Further, the paper provides a consistent methodology for differentiating S-DAC-GT costs and carbon intensity by region.
A Novel and Scalable Carbon Management Strategy for a Just Energy Transition
Authors: Buskie S. N. , Visman G. , Dekker M. , Sestak O.
Published: August 2023

A novel carbon credit supply stream at the center of the energy transition is presented that converts future plug and abandonment liabilities into assets. This approach offers unique benefits when compared to industry standard operating practices including reductions in Scope 1, 2 and 3 greenhouse gas emissions (GHG) and reduced methane intensities.

A macroeconomic study of U.S. hydrocarbon production was used to demonstrate the total addressable market and potential impact of the decarbonization strategy if deployed at scale. To facilitate scaled deployment of this carbon management approach the application of distributed ledger technology, a blockchain, is proposed. This technology must be coupled with trustworthy and reliable engineering assessments to satisfy the requirements within the voluntary carbon market. A case study is used to describe the economic and operational assessments an operator may take to apply the approach in practice.

The study shows the opportunity to generate 1 GtCO2e per year of carbon credits while improving the efficiency of U.S. oil and gas production. This is roughly equivalent to the GHG emissions of Japan, or 50% of the anticipated voluntary carbon market volume in 2030. (Crippa, 2022) The adaptation of best practice geoscience and engineering can be used to accurately assess the permanence and quantities of oil and gas eligible for crediting. The use of a blockchain to anchor the outcomes of the approach digitally in a meta-registry not only eliminates the possibility of double counting and provides transparency but also results in the world's first blockchain native carbon credit; a valuable offering within the voluntary carbon market. A case study shows that upstream suppliers of carbon credits could apply this approach and generate carbon credits with competitive breakeven price on the voluntary carbon market, meanwhile reducing their abandonment liabilities on their balance sheet. This novel carbon management strategy coupled with scalable technology deployment defines the future of a just energy transition.

The paper presents the combination of two novel approaches in service of accelerating the energy transition. It is the first of its kind to demonstrate the impact of advancing the cessation of production from oil and gas wells in return for carbon credits. Additionally, by marrying this approach with blockchain technology it provides a unique solution to allow this decarbonization strategy to be deployed at scale while fulfilling the requirements of the voluntary carbon markets.
A Novel Approach to Communicate a CO2 Storage Resources Management System Classification Framework
Authors: Chernik Paul S. , Caniggia Matteo
Published: August 2023

Carbon Capture and Storage (CCS) is a relatively young industry. In 2017 the SPE published the CO2 Storage Resource Management System (SRMS), as a framework for stakeholder communication. In 2022 it published the first SRMS Application Guidelines. However, working examples where the SRMS is used to communicate project status in the public domain are limited.

In 2023 the authors of this paper referred to the SRMS as the standard to complete a Competent Person's Report – a term used in the United Kingdom (UK) for an independent expert report designed to be shared with stakeholders to communicate the risk, uncertainty and commerciality of projects. This was believed to be the first application of the SRMS as a reporting tool to European equity markets.

While applying the SRMS, challenges were identified when using it as a tool for stakeholder communication.

This paper describes innovations developed to relate the SPE SRMS in a UK Competent Person's Report. First, a flowchart was developed to explain a key interpretation of the SRMS. Next a defined framework of technical milestones was developed to assess the maturity of a given technical topic within the SMRS. This was combined with radial data visualization. The combination allowed multiple storage sites to be compared simultaneously, and allowed a stakeholder to quickly identify what the maturity of technical analysis is for any given site.

We conclude that in the rapidly expanding space of CCS stakeholder engagement, the SRMS can play an important role. However, each user of the SRMS may interpret it differently and future implementation gaps will likely be identified. It is recommended that new methods of communicating SRMS challenges to the SPE be adopted, for rapid responses from the SPE to users and more consistent application of the SRMS across the globe.
Fugitive Emissions Study: How to Minimize and Control Methane Emissions While Utilizing Sand Separators

The goal for all oil and gas well sites is to have zero fugitive emissions. This is functionally difficult during flowback and early production operations, however, minimizing and managing fugitive emissions to net-zero is possible with planning and careful production equipment selection.

Sand separators are a critical piece of flowback and early production equipment. The process of removing sand at high pressure through blowing vessels down to atmospheric pressure, provides conditions where fugitive emissions can be created. In order to reduce the unnecessary fugitive emissions, horizontal or low angle Desanders have shown better performance over vertical or spherical sand separators as they have a larger sand holding capacity as well as a reliable sand measuring system resulting in fewer cleanouts and unnecessary releases of fugitive emissions (Wasfy et al, SPE-196142-MS 10). Furthermore, simple changes and additions to the rig-up design can be made to allow for all methane emissions to be captured during the process providing options for how to handle greenhouse gases in order to minimize environmental impact.

Using a spherical separator as a base measurement, for 1 m3 (264.2 gallons) of sand stopped a vertical geometry would produce 94.3% of the carbon emissions of the spherical vessel while the horizontal desander would produce 34.5% of the carbon emissions of the spherical and a low angle tilt would produce 14.7% of the carbon emissions. Also, through leveraging improved rig-up design with Horizontal and Low-Angle Tilt Desander, all methane resulting from the desanding process can be captured and directed to flare or vapor recovery reducing the equivalent CO2 released into the environment to near zero.

With the industry moving to achieve the minimal amount of environmental impact, operators are looking at every aspect of the process to reduce methane emissions, including the flowback process. The implementing of horizontal or Low-Angle Tilt Desanders, the sand measurement system, and the improved rig-up design allows for the elimination of open tanks on location during flowback. Further analysis, design improvements, and technology integration continues in order to achieve the goal of eliminating flaring and to conserve all methane produced by compressing into the pipeline and/or reserving to fuel other completions operations.
