Published: November 2024

Abstract
Blue hydrogen production technologies, derived from fossil fuels and offering high rates of carbon capture, occupy an important position in the climate initiatives ecosystem. By providing a clean, high-energy-density product from abundant, affordable fuels—all while relying on existing infrastructure and knowledge—these solutions fit readily into energy transition narratives. In this paper, a novel oxy-fuel combustion, amine-free, blue hydrogen generation process is introduced and compared against conventional, state-of-the-art performance and cost benchmarks using inputs keyed to the United Arab Emirates (UAE).
Adopting analysis methodologies from a reference study, this ultra-low-carbon (ULC) technology demonstrates a clear advantage over the reference autothermal reforming (ATR) with amine-based CO2 capture plant: namely, a 9.8% increase in effective thermal efficiency, a 6.6% increase in cold gas efficiency, a 26.8% decrease in baseline carbon intensity (CI) score, and a 21.2% decrease in the levelized cost of hydrogen. Oxy-fuel combustion, and the equipment associated with it, enables higher uses of waste heat from the hydrogen purification system. Furthermore, it reduces inefficiencies associated with nitrogen intrusion into the system and air's less ideal thermophysical properties as a thermal medium compared to CO2, thereby intensifying the blue hydrogen production process. The product streams—hydrogen and carbon dioxide—are kept separate throughout the process.
Compared to the amine-based post-combustion capture (PCC) systems conventionally paired with hydrogen production technologies, oxy-fuel combustion offers improved performance parameters and costs for CO2 compression, purification, and storage equipment. This is made possible by the comparatively simple exhaust stream separation process. Composed principally of water and carbon dioxide (avoiding contamination by nitrogen as occurs in processes relying on air-fired heating), the exhaust stream readily separates into process condensate and pipeline-ready CO2. Not only does this simplified CO2 clean-up and export configuration reduce both project capital (CapEx) and operating expenditures (OpEx) versus amine systems, but it also avoids generation of the toxic byproducts (e.g., nitramines and nitrosamines) associated with such systems. The authors expect that as the transition to Net Zero builds momentum, hazardous chemical byproducts like these will become scrutinized in much the same manner as greenhouse gas (GHG) emissions. With their local knowledge and significant capital resources, companies based in energy-abundant regions (e.g., the Middle East) are best positioned to anticipate and respond to such trends by adopting innovative solutions such as the technology discussed herein.
Soil Washing Case Studies within the Remediation Sector
Authors: Wilson Andrew. , Conway Amy. 
Published: November 2024

Abstract
Soil washing is increasingly popular in the remediation sector due to its effectiveness and versatility in treating contaminated soil. It is effective for a variety of contaminants, including organics, heavy metals, hydrocarbons, and pesticides, and allows for the treated soil to be recycled or reused. The growing adoption of soil washing is driven by stricter environmental regulations and advancements in technology, which enhance its efficiency and cost-effectiveness. The process involves assessing the site, excavating the soil, and then using a series of washing and separation techniques to remove contaminants. After treatment, the contaminants are properly managed, and the cleaned soil can be returned to the site or used for other purposes. Soil washing compares favorably to other remediation techniques due to speed of processing, relatively small footprint and ESG credentials. Recent case studies from Long Island, Saudi Arabia, and Kuwait highlight the successful application of soil washing in various settings, showing its effectiveness in managing diverse contamination issues and supporting sustainability goals.
Predicting the Elastic Properties of Anisotropic Reservoirs from Dipole Logging While Drilling Using Machine Learning
Authors: Maalouf E. , Chebli H. K. 
Published: November 2024

Abstract
The presence of a drill collar in logging-while-drilling acoustic instruments complicates the calculation of subsurface formation properties from acoustic logs. The collar's acoustic modes interfere with the formation's acoustic modes, which are essential for determining rock properties, particularly the flexural mode obtained from a dipole source. This interference is more pronounced in slower formations. Furthermore, most formations exhibit anisotropy, yet conventional log interpretation typically captures elastic properties in only one direction. To address these challenges, a method is proposed that overcomes tool effects and accurately calculates the complete set of elastic properties of rocks from the dipole flexural mode. The approach utilizes the modified matrix pencil algorithm to extract the flexural mode with minimal noise and interference, followed by a neural network to calculate the anisotropic velocities of rocks. The results demonstrate that the predicted elastic properties are accurate, and that the method is robust and fast, enabling real-time prediction of formation properties during drilling. This application optimizes the drilling and geosteering of wells for hydrocarbon and geothermal production, as well as carbon sequestration applications. Real-time inference of reservoir properties reduces non-productive time, minimizes drilling risks, and enhances the ability to precisely reach target reservoirs. Overall, this approach improves the efficiency and effectiveness of subsurface characterization, contributing to more sustainable energy exploration and carbon management strategies.

Operational Excellence: Re-Think Beyond Reuse, Reduce, Recycle in the Circular Economy
Authors: Palhares T. 
Published: November 2024

Abstract
The increased demand for remanufactured parts marks a paradigm shift for oil and gas operators. As companies seek to achieve their individual sustainability goals, returning core equipment parts and choosing remanufactured parts are both key tactics to help reduce waste and make sustainability gains. Returned parts and assemblies are disassembled to their piece parts, cleaned and inspected before undergoing processes such as laser cladding, machining, metal deposition and other advanced salvage procedures. The remanufactured parts are then assembled into like-new components with like-new quality and warranty. This enables oil and gas companies to benefit from using high-quality and economical parts while supporting the circular economy.
This paper will share data and examples from the field that illustrate how the responsible use of remanufactured parts impacts the circular economy in the EMEA region.

Abstract
The difficulties in hydrogen storage and transportation have become the main bottleneck that restricts the large-scale development of the hydrogen energy industry. As a solution for hydrogen storage, ammonia has a high hydrogen storage density, provides mild storage conditions, possesses mature and complete conditions for production, storage and transportation, providing a means to address the problem of hydrogen storage and transportation. However, the question such as whether the process is economical is still lack of enough research. This study is aimed to summarize the current development of synthetic ammonia industry and discuss the development path of ammonia in hydrogen energy industry. Based on the upon analysis, we propose thoughts on the development of the world synthetic ammonia industry, and points out four development paths. We analyzes economy of synthetic ammonia made from electrolytic hydrogen as an alternative to coal, cost of ammonia as a carrier for transportation of hydrogen. When the electricity price is RMB 0.2/kWh, the cost of green ammonia production is RMB 2,095/t, which is comparable to the cost of gray ammonia production when the coal price is RMB 900/t; when the electricity price is RMB 0.1/kWh, the cost of green ammonia production is RMB 1,115/t, which is comparable to the cost of gray ammonia production when the coal price is RMB 277/t. Four feasible development paths of China's ammonia industry are proposed. Firstly, integrating green hydrogen into ammonia synthesis plants to expand green ammonia production capacity and reduce carbon emissions. Secondly, consuming renewable energy electricity to produce ammonia. Thirdly, efficiently integrating byproduct hydrogen resources into ammonia production to enhance economic benefits. Last but not least, using offshore wind power to develop distributed and miniaturized ammonia synthesis projects.

Abstract
Petroleum Development Oman PDO has set an ambitious target of achieving net-zero emissions by 2050. In alignment with this goal, this paper showcases how high performance can be achieved while reducing the carbon footprint of well construction.
Petroleum Development Oman PDO achieves high performance through a series of continuous improvement initiatives, known as the "Well Staircase." These initiatives encompass well design optimization, the adoption of new technologies, operational efficiency enhancements, and cementing design optimization. A comprehensive value creation workshop, involving all stakeholders, was conducted to consolidate these initiatives. Furthermore, this workshop quantified the planned cost savings and time reductions. To operationalize Petroleum Development Oman PDO's net-zero emissions aspiration, a new dimension was introduced to these key initiatives - a reduction in Carbon Dioxide CO2 emissions.
Illustrative examples of these initiatives include slimming the well design in the A-field, resulting in an 11% reduction in costs per well, a saving of 9.8 days, and a decrease in CO2 emissions by 245 tonnes. Replacing Motorized Reamers MSRs yielded a 1% reduction in well costs and a 0.4-tonne reduction in CO2 emissions due to transportation. The optimized slurry formulation led to a 15-tonne reduction in CO2 emissions per well. The elimination of round trips by employing a risk-assessed hole condition approach resulted in a cost saving of 1.6% per well, a time saving of 2.5 days, and a reduction in CO2 emissions by 62 tonnes.
This innovative approach demonstrates how high performance can be achieved while simultaneously decarbonizing well construction, providing valuable insights and practical strategies for the industry's journey toward a sustainable future.

Abstract
The southern regions of the Arabian plate in Oman feature remarkable exposures of Ediacaran strata, which hold significance not only for their association with subsurface hydrocarbon reserves but also for hosting evidence of the world's largest negative marine Carbon excursion "The Shuram-Wanoka Anomaly". In contrast, analogous Ediacaran sequences present in the northern sections of the plate within the Kingdom of Saudi Arabia, have yet to reveal their hydrocarbon potential or indication of the Shuram anomaly and this disparity has fueled geological inquires. Our study focused on two well-exposed Ediacaran successions, the "Dhaiqa Basin" being the most northern Ediacaran basin in the Kingdom, and the "Antaq Basin" being the southernmost basin. We have conducted a comprehensive multiproxy characterization including sedimentological, micropaleontological, mineralogical and isotopic measurements. The findings unveiled some distinct depositional characteristics and diagenetic histories in these sediments despite their similar age. In the kingdom of Saudi Arabia, the northern most Ediacaran basin, the Dhaiqa basin exhibit carbonate facies with some microfossils suggesting a shallow-water environment, whereas the southernmost basin in the Kingdom, the Antaq basin is predominantly siliciclastic indicating a terrestrial origin. Stable isotopic results of Carbon and Oxygen further advocate on the isolated nature of these deposits with values diverging significantly from the global sea values as well as values recovered from Oman. The dissimilarity is attributed to the presence of the Najd Fault system in northern portions of the Arabian plate. Although the deposition in Oman is identified as a shallow open marine environment, the sediments in Saudi Arabia indicate deposition mainly in isolated basins influenced by the movements associated with the Najd Fault system. Although certain carbonate lithofacies in northern Dhaiqa Basin contain carbonaceous organic matter, resulting in a fetid odor in freshly broken rock samples, the Total Organic Carbon (TOC) results indicate an overall organic content ranging below 0.2%, classified as type IV. However, akin to their Omani counterparts, the proximity of these sediments to subsurface evaporites in the southern parts of the kingdom suggest a potential prospect for future hydrocarbon exploration.

Significant advancements in seismic imaging of carbonate strata over the past decades have transformed our scientific comprehension of carbonate sediment accumulation and alteration. These breakthroughs have far-reaching implications, extending from hydrocarbon exploration to the fields of geomorphology and the study of paleoclimate changes (Hendry et al., 2021). Through the analysis of 3D seismic data gathered for hydrocarbon exploration, we have gained a deeper understanding of how strata at the carbonate platform margin accumulate, forming patterns that are progradational, aggradational, and retrogradational. These patterns chronicle a long-term history of variations in accommodation space, sediment production, and sediment transport (Dujoncquaoy et al., 2018).
This study was initially conducted to explore the distribution of lower Habshan Formation and its reservoirs, aiming to uncover potential opportunities within the UAE. It offers a comprehensive regional well and seismic based synthesis of the lower Habshan Formation, encompassing nearly all eastern onshore areas of Abu Dhabi. It leverages new interpretations from the latest mega 3D seismic data, various seismic attribute maps, and well data to provide a detailed understanding of the lower Habshan Formation. The regional facies and maps developed for the lower Habshan during this study offer a novel and more precise method for predicting strike-parallel continuity and lateral facies variability in prospective reservoir targets, as well as identifying new play concepts.
Achieving CO2 Emissions Reduction by Overcoming Well Integrity Challenges in High Pressure and Narrow Window Environments: A Case Study of a Giant Middle East Deep Gas Field
Authors: Ovwigho Efe Mulumba , Almuallim Mustafa , AlAwfi Mohammed 
Published: November 2024

Abstract
While drilling the 12″ section, a water bearing formation is encountered prior to reaching the target gas reservoir formation. This formation is sporadically-charged across the field requiring a KMW up to 21 ppg. This poses major well integrity challenges as it becomes critical to avoid losses in the resulting narrow mud window and ensuring proper cement placement. Inability to predict the mud window makes it impossible to define the drilling strategy to implement.
To understand the drilling challenges, in-depth offset wells analysis was performed. Based on mud weights required to drill across the reference formation, the heat-map for historical KMW was created based on confirmed well control events. It was difficult to predict formation-flow potential. Field geomechanics studies was then carried out to correlate the mapping done earlier. Once possibility of encountering abnormally pressured formation is flagged, in order prevent drilling risks such as loss circulation and poor cementing placement, proactive measures such as: Improved influx monitoring, drilling/cementing fluids optimization, liner-and-tieback system implementation, Managed Pressure Drilling/Cementing, optimized casing design were put in place.
The integrated approach led to quick influx detection, proper definition of mud window, i.e. Pore Pressure and Fracture Gradient together, helped to prevent the losses, design of fit-for-purpose bridging strategy to ensure full drilling fluid column at all time while avoiding the cost associated with fluid losses. Drilling the section with Managed Pressure Drilling system (MPD) and low mud weight led to achievement of high ROP leading to substantial time saving. The Liner string was run and Managed Pressure Cementing (MPC) was implemented to manage the equivalent circulating density (ECD), avoid losses and ensure good zonal isolation. Overall non-productive time was reduced by 40% as compared to the offset wells in the area.
Integrated drilling approach delivers great gains when there is good understanding of the well integrity challenges and solutions are tailored to solve identified problems.

Abstract

Calcium signaling is crucial across various cell types, but its spatiotemporal dynamics remain difficult to study due to limited methods. Optogenetics, with its high precision, can address this challenge. In this study, we introduced the channelrhodopsin variant ChR2 XXM2.0, which exhibits high light sensitivity and enhanced Ca2+ conductance in Xenopus oocytes, into bone marrow-derived megakaryocytes through viral transduction, aiming to clarify the poorly understood role of Ca2+ dynamics in these cells. ChR2 XXM2.0 expression was confirmed in megakaryocyte membranes, and its functionality validated through whole-cell patch-clamp and calcium imaging. Localized activation of ChR2 XXM2.0 at the cell periphery induced cell polarization, dependent on localized calcium influx, myosin IIA, and integrin αIIbβ3-fibrinogen interaction. Furthermore, we generated a transgenic mouse line with Pf4-Cre-dependent expression of ChR2 XXM2.0, enabling optogenetic manipulation of anucleate blood platelets via light-triggered calcium signaling. Illumination induced phosphatidylserine and P-selectin exposure in spread platelets. Our results highlight the importance of asymmetric subcellular calcium events in megakaryocyte polarity and demonstrate the feasibility of manipulating platelet function using optogenetics. Taken together, our study introduces the ChR2 XXM2.0 construct and its corresponding Cre-dependent transgenic mouse line as powerful tools for manipulating subcellular Ca2+ signaling, with potential applications for different cell types.
