Abstract
The Oil and Gas (O&G) industry is facing unparalleled challenges in aligning with sustainable practices against the backdrop of increasing global concerns about climate change and social responsibility. This paper introduces the concept of ESG Total Cost of Ownership (ESG TCO) as a transformative framework, facilitating the understanding of Environmental, Social, and Governance (ESG) factors in supplier selection processes within global value chains, ultimately enhancing operational sustainability and ensuring business continuity.
Through a case study developed in an O&G company in the global subsea industry, this paper extracts insights from empirical studies and data analysis. The study's scope interrogates the inadequacies of traditional Total Cost of Ownership (TCO) models to fully account for the broader spectrum of costs incurred by O&G operations. Leveraging a comprehensive literature review, this research explores the integration of ESG indicators into the TCO model, highlighting the challenges and opportunities within complex and interconnected supply chains. It proposes a nuanced methodology for integrating sustainability into cost analysis, addressing the unique obstacles and advantages presented by the sector.
The narrative commences with an examination of the environmental legacy and evolving societal expectations confronting the O&G industry, particularly within the global subsea sector. It assesses the ESG TCO framework's efficacy in offering a holistic evaluation of costs and sustainability building blocks encompassing human Rights, safety and carbon intensity factors. The analysis presents strategic recommendations for companies seeking to enhance their sustainability profiles and navigate the transition towards more sustainable operations. By situating ESG TCO as an essential methodology for industry players, this research contributes valuable perspectives to the academic literature on responsible business conduct within the energy sector, particularly those engaged in the global subsea industry. Also, from practical lenses it underscores the strategic relevance of adopting ESG TCO in fostering sustainability, highlighting its role in guiding companies through the complexities of modern supply chains, regulatory environments, and customer requirements.
Based on the imperative of pursuing financial gains and embracing sustainability in worldwide industries, the adoption of the ESG TCO framework offers a strategic pathway. It advances sustainability within global supply chains, positioning it as a cornerstone for selecting isonomically suppliers based on their sustainable performance, considering future client requirements towards the value chain and fostering resilient business models amidst the dual challenges of adhering to environmental responsibilities and navigating societal pressure.

Authors: Danso D. K. , Bicerano Jozef , Heller Douglas P. , Barati R. G. 
Published: August 2024

Abstract
This paper details the formulation and characterization of a novel nanoparticle system composed of polyethyleneimine (PEI) and dextran sulfate (DS) for direct lithium extraction (DLE) from bulk oilfield brines sourced from North America.
Different mass ratios of solutions of PEI and DS at varied concentrations (1 -10wt%) were prepared in the presence of 150 ppm Li concentration to yield nanoparticle systems that electrostatically entrap the Li ions in the solution. The nanoparticles produced were characterized by their size, zeta potential (charge), polydispersity index, and count rate with a particle size and zeta potential analyzer equipment. Inductively coupled plasma optical emission spectroscope (ICP-OES) and Total Organic Content-Total Organic Nitrogen (TOC-TON) analyzer equipment were coupled to analyze the Li entrapment efficiency within the nanoparticle systems.
Results indicated that the final pH, size, and charge of the nanoparticles were influenced by the mass ratio of PEI and DS. Particle size exhibited a decreasing trend with increasing PEI: DS mass ratios from 1 to 5, while the opposite trend was observed for mass ratios lower than 1. Zeta potential generally became more positive with higher PEI: DS mass ratios. Meanwhile, negatively charged nanoparticles were observed at lower ratios. The extraction efficiency was optimum between 10 and 9 wt.% concentrations of PEI and DS with positively charged nanoparticle systems exhibiting greater entrapment. The maximum observed entrapment efficiency was approximately 48%, achieved through bilayer deposition.
Integrating this innovative nanoparticle-based DLE method into existing lithium treatment processes can significantly enhance lithium recovery rates, either in combination with membrane extraction techniques or as a standalone methodology following the removal of divalent cations in the pretreatment phase.
Measurement of Diffusivity of Supercritical CO2 in Formation Brines at Reservoir Conditions for CCS Applications
Authors: Oyagha Sherry , Ratnakar Ram R. , Dindoruk B. 
Published: August 2024

Abstract
CO2 diffusivity in brines plays an important role in CO2 migration/distribution in CCS processes. Pressure-decay tests are one of the most common methods to determine gas diffusion in liquids. However most of the existing studies are limited low pressure and temperature (PT) conditions. A few high PT studies with NaCl brines exist in the literature. Main objective of this work is to provide novel experimental data with supercritical CO2 and with extended range of salinities at reservoir conditions (i.e., high pressure and temperature). In this article, we extend the methodologies used in previous studies (Ratnakar and Dindoruk, 2015-SPEJ-170931-PA and 2019-SPE-181514-PA) for CO2-brine systems where we perform diffusivity experiments for CO2-brine systems containing only NaCl. The inversion technique is based on the late transient model technique developed in refs. 34 and 35while the effect of reactive nature of CO2 (forming carbonic acids during dissolution) is also discussed. In particular,
The results are presented at 60°C and 1400 psi with the salinity range of 0 – 200,000ppm. The results show that the diffusivity values are aligned with the trends reported in literature. Most importantly, the work and methodology can be extended to any other reservoir conditions and formation brines.
The main novelty of this work lies in the presentation of new experimental data for diffusivity of supercritical CO2 in brine at extended range of salinities and reservoir PT conditions. Additionally, the effect of reactive nature of CO2 on the inversion of the pressure-decay models are included in contrast to the existing work where such effects are not considered.
Feasibility of Using Stranded Wyoming Wind for Hydrogen Production
Authors: Buckhold Sarah , Naughton Jonathan 
Published: August 2024

Abstract
The state of Wyoming features some of the best wind resources in the country. However, much of this resource is currently undevelopable due to its distance from existing electrical interconnects. This results in the wind being deemed a stranded resource, or a resource that is not currently able to be utilized. The production of hydrogen through electrolysis could enable the transport of wind energy through means other than the electrical grid, such as rail, highway, or pipeline. The objective of this study is to investigate the financial feasibility of creating hydrogen from stranded Wyoming wind resources. This is completed by using the Wind Integrated National Dataset Toolkit Long-term Ensemble Dataset (WTKE-LED), a national weather model that covers the continuous United States, Alaska, Hawaii, and offshore regions. The portion of this expansive dataset used in this study includes 20 years of modeled weather data that is output hourly on a 4-km grid to allow for preliminary analysis of wind resources. Wyoming hub height wind speeds from the WTKE-LED are used to map the wind resource of Wyoming. Using the 2023 Annual Technology Baseline (ATB) produced by NREL (Mirletz 2023), wind energy production costs are estimated. Using these energy production costs and corresponding Levelized Cost of Energy (LCOE) for the wind energy, and the DOE Hydrogen and Fuel Cells Program Record titled Hydrogen Production Cost from PEM Electrolysis - 2019 (Peterson 2020), the cost of produced hydrogen via electrolysis is then estimated and visualized. This visualization is then overlayed with potential methods of energy transport such as the electric grid, highway, rail, and pipeline.
Results show that Wyoming has many locations of good, but stranded wind resources. While these resources may not be close to existing electrical infrastructure, some are much nearer to existing rail, highways, or pipelines that could enable hydrogen transport. As wind and hydrogen production technologies mature, as forecasted in the ATB (Mirletz 2023) and the DOE Hydrogen and Fuel Cells Program Record (Peterson 2020), the resultant map shows several areas of the state that may be able to use stranded wind to produce hydrogen for under $2/kg by 2035. This is far under the $4.48/kg estimate found for that year in the DOE Hydrogen and Fuel Cells Program Record. Much of this cost reduction is due to the inexpensive electricity coming from the wind plant due to high wind power capacity factors and lack of costs associated with connecting the wind plant to the grid.
Geomechanical Considerations for Hydro Energy Storage in Fractured Wells
Authors: Al Balushi F. , Taleghani A. Dahi 
Published: August 2024

Abstract
Fractured wells present an innovative opportunity for storing excess renewable energy during periods of low demand by leveraging the elastic deformation of subsurface formations and the lifting of overburden to store and discharge water within hydraulic fractures. The efficiency of these Geomechanical Pumped Storage (GPS) systems heavily relies on the hydraulic connectivity between the wellbore and fractures. This study aims to model various well and fracture configurations to identify optimal designs for enhancing hydro energy storage in fractured wells. We constructed mechanical earth models for both vertical and horizontal wellbores. Injection, shut-in, and production cycles were simulated for varying well/fracture layouts under diverse geological conditions. The presented coupled approach explicitly models fluid flow and rock deformation interactions. In addition, we performed comprehensive sensitivity analyses to evaluate the impact of key parameters including formation permeability, fracture conductivity, fracture geometry, and leakoff coefficient on system performance. Based on this, we determined optimal designs to exploit stored elastic energy and subsurface formation lift by calculating net power output and the associated system efficiency. Simulation results indicate significant GPS performance variations based on wellbore/fracture orientations. Fracture geometry proved critical in determining net power output. Moreover, horizontal wellbores showed higher efficiency due to the larger accessed reservoir volume compared to vertical wellbores. Understanding geomechanical factors during injection/production cycles is crucial for assessing subsurface formations' potential as effective energy storage/release mediums.

Published: August 2024

Abstract
The main objective of this study is to investigate the impact of subsurface conditions on surface networks and vice-versa to highlight correlated challenges and establish best-practice guidelines to be taken into consideration for carbon dioxide (CO2) injection networks to optimize surface and subsurface operations.
This study involved CO2 transport and injection well modelling for a variety of surface and subsurface conditions. This includes the simulation of onshore and offshore transport conditions as well as injection into depleted reservoirs and saline aquifers. Steady state and transient operations were performed on the injection well to investigate the surface and subsurface challenges associated with CO2 phase behavior in the system.
In this work, an integrated CO2 transport and injection network was modelled for various operating scenarios during the life cycle of a CCS project. The challenges encountered in the entire system including Joule-Thomson (JT) cooling, hydrate formation and multiphase flow are highlighted with field case studies presented.
In the context of Carbon Capture, and Storage (CCS) projects, it is essential for CO2 injection wells to meet projected CO2 injection rates for both economic as well as regulatory requirements. The regulatory consequences could be significant, with the operator potentially held responsible for carbon credits until adequate well capacity is attained.
There are several subsurface and surface conditions which impact the performance of either the surface and subsurface operations and these operational scenarios are discussed in an integrated study so that the entire CCS system can be optimized to meet transport and injection requirements.
New Geothermal Gradient Data Allows for Evaluating Applications in Albania and Kosova
Authors: Hoxha B. B. , Soto J. I. , Bega Z. , Zuna A. 
Published: August 2024

Abstract
There is a growing interest in geothermal energy across various applications, including conventional geothermal, Enhanced Geothermal Systems, deep-loop systems, geopressured energy storage, geothermal brine extraction, and the re-utilization of abandoned oil and gas wells. This paper explores new horizons for geothermal applications, specifically assessing suitability for energy-deficient nations like Albania and Kosova. The study employs a joint case study approach, acknowledging the interconnected energy program shared by both countries. Geothermal energy has gained significant traction in addressing the need for low-carbon solutions, with nations increasingly leveraging their natural resources. Despite differing energy mixes, Albania and Kosovo have forged a mutually beneficial energy plan. With both countries facing energy addition challenges and an energy precarity rate of approximately 23-25%, geothermal applications emerge as potential for harnessing abundant, renewable sources. The study delves into novel aspects, including a first-time evaluation of a geothermal gradient in Albania at 7 km depths and an assessment of critical minerals like lithium, radium, and strontium in Kosovo's geothermal brine. The global shift towards sustainable energy sources is evident in many nations’ strategic reevaluation of conventional options, such as fossil fuels. Despite Albania's predominantly ‘green’ electricity production, with 94% hydropower, 3% fossil fuels, and 3% alternative renewables, the country seeks to stabilize its energy mix for self-sufficiency. In contrast, Kosovo heavily relies on lignite, constituting over 94% of its energy sources, with 6% from other resources. Despite efforts to diversify through investments in wind and solar, scaling up remains a challenge.
This study addresses the gap by utilizing previously untapped data and presenting geothermal gradients that identify optimal geothermal applications. For instance, in Albania's Ardenice area, the highest maximum temperature of 113°C is identified, demonstrating the potential for geothermal energy to contribute significantly to the energy mix of both Albania and Kosova. This paper delves into the assessment of geothermal gradients for Albania, exploring suitable geothermal applications for its micro-economic industry rather than energy production. In contrast, critical mineral assessments for Kosovo will be conducted on geothermal brines from the Vardar and Dukagjin basins. These analyses highlight the necessity for tailored technical expertise due to diverse geo- mechanical and operational challenges across regions and applications, paving the way for informed decision-making and sustainable utilization of geothermal resources.

Published: August 2024

Abstract
Leveraging on existing seismic dataset and merging different vintages together to help improve signal to noise ration and image fields that are straddled on different seismic datasets is key and essential for planning infill wells and near field exploration. A merge of three different seismic datasets was done to help better image the Lemur field. After the merge, an optimum velocity model was built, and migration carried out. This led to a better resolved broadband seismic image which is essential in understanding hydrocarbon fields and unlocking more reserves. For proper seismic interpretation to take place, clearly understanding the stratigraphic features to map, in this case, straddling across fields, is key to delivering the structural framework and thus delineating the reservoir architecture. This is tied to having good events continuity and true amplitudes in the seismic dataset. In this paper, reprocessing an already existing seismic dataset with recent technology (broadband processing) have shown more structural and stratigraphic features which were not clear in the legacy seismic of the Lemur field, onshore Niger Delta, Nigeria. The most impacting part of the workflow deployed in this work is the Merge of the different surveys, the broadband processing and accurately estimating the velocity used for migration. On the basis on this new seismic dataset, a new infill production well was drilled in the field with success.
