Subjects: subject: Geometric Topology (math.GT)
subject: FOS: Mathematics

description: Topological quantum field theories with gauge group $\textrm{SU}_2$ associate to each surface with marked points $Σ$ and each integer $r>0$ a vector space $V_r (Σ)$ and to each simple closed curve $γ$ in $Σ$ an Hermitian operator $T_r^γ$ acting on that space. We show that the matrix elements of the operators $T_r^γ$ have an asymptotic expansion in orders of $\frac{1}{r}$, and give a formula to compute the first two terms in terms of trace functions, generalizing results of Marché and Paul.

description: While the pulmonary artery catheter (PAC) is still interesting in specific situations, there are many alternatives. A group of experts from different backgrounds discusses their respective interests and limitations of the various techniques and related measured variables. The goal of this review is to highlight the conditions in which the alternative devices will suffice and when they will not or when these alternative techniques can provide information not available with PAC. The panel concluded that it is useful to combine different techniques instead of relying on a single one and to adapt the "package" of interventions to the condition of the patient. As a first step, the clinical and biologic signs should be used to identify patients with impaired tissue perfusion. Whenever available, echocardiography should be performed as it provides a rapid and comprehensive hemodynamic evaluation. If the patient responds rapidly to therapy, either no additional monitoring or pulse wave analysis (allowing continuous monitoring in case potential degradation is anticipated) can be applied. If the patient does not rapidly respond to therapy or complex hemodynamic alterations are observed, pulse wave analysis coupled with TPTD is suggested.

description: We investigate the possibility that the galactic dark matter exists in an scenario where the phantom field is responsible for the dark energy. We obtain the statically and spherically approximate solution for this kind of the galaxy system with a supermassive black hole at its center. The solution of the metric functions is satisfied with $g_{tt} = - g_{rr}^{-1}$. Constrained by the observation of the rotational stars moving in circular orbits with nearly constant tangential speed in a spiral galaxy, the background of the phantom field which is spatially inhomogeneous has an exponential potential. To avoid the well-known quantum instability of the vacuum at high frequencies, the phantom field defined in an effective theory is valid only at low energies. Under this assumption, we further investigate the following properties. The absorption cross section of the low-energy $S$-wave excitations of the phantom field into the central black hole is shown to be the horizontal area of the central black hole. Because the infalling phantom particles have a total negative energy, the accretion of the phantom energy is related to the decrease of the black hole mass which is estimated to be much less than a solar mass in the lifetime of the Universe. Using a simple model with the cold dark matter very weakly coupled to the "{\it low-frequency}" phantom particles which are generated from the background, we show that these two densities can be quasi-stable in the galaxy.

Global revenues from wild seafood products
Creators: name: Van Der Meer, Liesbeth
Publisher: name: University of British Columbia
Year: 2012

description: The present study quantifies the revenues generated by marine seafood in the retail and restaurant sectors. Also, since one third of total marine catch is used to produce fishmeal, revenues generated by this commodity were calculated based on the percentage of meat products that originated from fishmeal inclusion in compound-feed formulas. In total, wild seafood products generated revenues of US $318 billion in the year 2005. To arrive at this estimate I first developed a global database of seafood retail revenues, which is used to analyze fish retail values per tonne at the regional and global level. This database includes 192 maritime and non-maritime countries. The findings are that in 2005, revenues, from wild marine seafood in the retail sector alone reached US $210 billion. Revenue from seafood restaurants were calculated based on estimations of country GDP expenditures in the hotel and restaurant sector. By analyzing the data on 30 countries (US and EU countries) where primary data on restaurants and hotel were reported separately, I estimate that on average, in the US and the EU countries where data is available, 43 percent of revenues from hotels and restaurants are attributable to restaurant sales. Wild seafood restaurant sales represented 17-25% of global restaurant sales generating revenues of US $94 billion. Finally, in order to estimate the revenues from the fishmeal sector, calculations were made based on farmed fish and animal meats, which include fishmeal in their compound feed preparation. Revenues derived from animal and fish meats were calculated based on their FCR (food conversion ratios) and inclusion rates of fishmeal for each species. I estimate that US$14 billion were generated by the inclusion of fishmeal in meat products.

The first shows that a Kähler-Ricci soliton induced by the homogeneous metric of a homogeneous bounded domain is trivial, i.e. Kähler-Einstein. In the second one we prove that a homogeneous bounded domain and the flat (definite or indefinite) complex Euclidean space are not relatives, i.e. they do not share a common Kähler submanifold (of positive dimension). Our theorems extend the results proved in [A. Loi, R. Mossa, Proc. Amer. Math. Soc. 149 (2021), no. 11, 4931-4941] and [X. Cheng, Y. Hao, Ann. Global Anal.

description: The Canadian jurisprudence relating to subject-matter patentability has developed errors that are inconsistent with over a century of comparatively stable interpretation of s. 27(8) of the Patent Act. The errors are the adoption of a physicality requirement and an approach to identifying the bar against mere scientific principles and abstract theorems that discounts the actual implementation of the invention and focuses instead on the form of the invention by looking for physical components or effects. This approach also is characterized by the failure to separately consider the issues of the bar against mere scientific principles, obviousness, indefiniteness, overbreadth/lack of support and meeting the definition of invention. The historical development of s. 27(8) and s. 2 of the Patent Act is analyzed and the origins of these errors are discussed, including a review of the most recent relevant jurisprudence. A more correct and concise approach to determining subject matter patentability would evaluate s. 27(8), after purposive construction, purely on the basis of whether the invention as claimed recites a well-defined application and specific implementation of the scientific principle or abstract theorem. A more correct determination of whether a claimed invention meets the definition set out in s. 2 would identify whether, after purposive construction, the invention has a utilitarian application for the benefit of humanity that does not fall within the liberal arts or another judicial exception. Separately from these determinations, and in no particular order, the other requirements for patentability may also be considered.

description: The problem with clearance
Clearance is the removal of a substance from blood, expressed as a volume (milliliters) over time (minutes). However, changes in lactate levels are the sum of ongo- ing production and removal from the blood by excretion (e.g., urine, sweat) and its metabolism (e.g., uptake by cells as a direct source of energy, conversion to glucose by the liver). To talk about “lactate clearance” [1] when actually describing a decrease in blood level is wrong and misleading. Following the review of 96 studies, Vincent et al. [1] concluded that given recent evidence, measure- ments every 1–2 h would give clinically relevant data about the decrease in lactate levels.
Doping Dependence of Hall Coefficient and Evolution of Coherent Electronic State in the Normal State of Fe-based Superconductor Ba$_{1-x}$K$_{x}$Fe$_{2}$As$_{2}$

description: We investigated the in-plane transport properties of the Fe-based superconductor Ba$_{1-x}$K$_{x}$Fe$_{2}$As$_{2}$ with a wide composition range $0 \leq x \leq 0.55$. We show that the doping dependence of the Hall coefficient is well-described by the Boltzmann equation for a two-band system with a rigid-band approximation. We successfully deduced transport parameters, which suggested that holes with heavier mass conduct more smoothly than electrons. Moreover, the temperature variation of the Hall coefficient indicated that an anomalous coherent state characterized by heavy quasiparticles in hole bands evolved below $\sim100$ K, predominantly in the optimal and overdoped regions. We argue that this phenomenon can be understood in relation to the pseudopeak structure observed in angle-resolved photoemission spectroscopy.

description: Understanding the dynamics of large-carnivore populations is critical in light of expanding human activities that may alter their natural habitats. In this thesis, I examine the effects of both human-induced disturbances and natural environmental factors, on the population density and habitat use of wolverines (Gulo gulo) in the Canadian Rocky Mountains and the Columbia Mountains of British Columbia and Alberta, Canada. Carnivores, such as wolverines, are sensitive to human-caused mortality and large-scale habitat changes as they roam widely and have low reproductive rates and densities. Human impacts, including overharvest, ecosystem changes due to resource extraction and additional decreases in habitat quality because of recreation, may pose growing challenges to wolverine conservation. I employed non-invasive genetic sampling, remote camera surveys and spatial capture-recapture techniques to assess population trends and offer critical insights into how wolverines respond to both human-caused pressures and natural environmental factors. Sampling at a population scale, my research provides evidence that recreational activities not only impact habitat use, but can have detrimental impacts on wolverine population density, even within protected areas. While protected areas appear to be vital for maintaining wolverine populations, especially if they are harvested on unprotected lands, edge effects and high disturbance levels from recreation may compromise their effectiveness. My work thus suggests that human disturbances have both direct and indirect effects on wolverine density, with female wolverines being particularly impacted. Areas with higher road density and recreational activity exhibit lower population densities, highlighting the need to manage human access if protection is a societal objective. I also investigated the role of bottom-up factors, such as persistent spring snow cover, which is associated with wolverine ecology and reproduction. The interaction between natural and anthropogenic factors creates complex patterns in habitat use, but by identifying key drivers of population decline, I offer important conservation implications, emphasizing the necessity for integrated management strategies that balance human land use with the needs of wildlife species. These findings underscore the broader applicability of my research to other carnivores facing similar threats, providing a foundation for future conservation efforts.

Resuscitation
Septic shock
Lactates

description: Septic shock is a highly lethal condition. Early recognition of tissue hypoperfusion and its reversion
are key factors for limiting progression to multiple organ dysfunction and death. Lactate‐targeted resuscitation is the gold‐standard under current guidelines, although it has several pitfalls including that non‐hypoxic sources of lactate might predominate in an unknown proportion of patients. Peripheral perfusion‐targeted resuscitation might provide a real‐time response to increases in  ow that could lead to a more timely decision to stop resuscitation, thus avoiding  uid overload and the risks of over‐resuscitation. This article reports the rationale, study design and analysis plan of the ANDROMEDA‐SHOCK Study.
Methods: ANDROMEDA‐SHOCK is a randomized controlled trial which aims to determine if a peripheral perfusion‐ targeted resuscitation is associated with lower 28‐day mortality compared to a lactate‐targeted resuscitation in patients with septic shock with less than 4 h of diagnosis. Both groups will be treated with the same sequential approach during the 8‐hour study period pursuing normalization of capillary re ll time versus normalization or a decrease of more than 20% of lactate every 2 h. The common protocol starts with  uid responsiveness assessment and  uid loading in responders, followed by a vasopressor and an inodilator test if necessary. The primary outcome
is 28‐day mortality, and the secondary outcomes are: free days of mechanical ventilation, renal replacement therapy and vasopressor support during the  rst 28 days after randomization; multiple organ dysfunction during the  rst 72 h after randomization; intensive care unit and hospital lengths of stay; and all‐cause mortality at 90‐day. A sample size of 422 patients was calculated to detect a 15% absolute reduction in mortality in the peripheral perfusion group with 90% power and two‐tailed type I error of 5%. All analysis will follow the intention‐to‐treat principle.
Conclusions: If peripheral perfusion‐targeted resuscitation improves 28‐day mortality, this could lead to simpli ed algorithms, assessing almost in real‐time the reperfusion process, and pursuing more physiologically sound objec‐ tives. At the end, it might prevent the risk of over‐resuscitation and lead to a better utilization of intensive care unit resources.

description: Allogeneic hematopoietic stem cell transplantation (HCT) is a curative therapy for hematological malignancies. Two major allo-immune reactions take place in the recipient after HCT: the beneficial graft versus leukemia (GvL) wherein the donor immune cells identify and eradicate the leukemic cells of the recipient and the graft versus host (GvH) where the donor immune cells react against the normal cells of the host causing a debilitating illness called graft versus host disease (GvHD). The primary objective of this doctoral research was to distinguish between GvH and GvL allo-immune reactions by meticulously profiling the immune recovery at multiple time points post-HCT. Immune reconstitution in both adult and pediatric HCT recipients was evaluated at the transcriptomic level via gene expression profiling of 579 immunity-related genes using NanoString technology and at the cellular level through flow cytometric analysis of cell subset counts. Peripheral blood mononuclear cells from HCT recipients were analyzed at Day14, Day28, Day56, and Day84 posttransplant. An immune signature characterized by higher counts of T cells and overexpressed T cell-related genes, was identified in patients who developed acute GvHD grades 2-4 as early as Day14 posttransplant. The gene expression signature showing overexpressed T cell related genes especially CD161 expressing cytotoxic T cells was validated in an independent validation cohort. T cell counts and related transcriptomes were notably higher in cytomegalovirus (CMV) seropositive donor and recipient (D+R+) patients compared to other serostatus groups. The recovery pattern was similar in both adult and pediatric patients. The influence of CMV D+R+ on T cell reconstitution was not significant at early time points (Day 28) but became evident at 2 and 3 months post-transplant. Signatures indicating a lack of GvL response were observed at 3 months (Day 84) post-transplant characterized by downregulated expression of CD8 Tcell genes, including TIGIT and EOMES in patients at high risk of relapse. While this study succeeded in partially differentiating GvH and GvL allo-immune reactions through temporal and differential T cell gene expression profiling, further comprehensive transcriptomic analysis in larger cohorts is essential for a complete understanding of the separation between GvH and GvL.

description: This thesis explores advanced catalysts for energy conversion, focusing on two key projects. The first project explores doped PtRu catalysts to improve CO tolerance in proton exchange membrane (PEM) fuel cells. Using density functional theory (DFT), Pd- and Rh-doped PtRu catalysts were identified as promising due to their resistance to CO poisoning. These findings suggest the potential to enhance PEM fuel cell anode durability and reduce fuel purification requirements, though experimental validation is needed. The second project focuses on nitrogen-doped carbon catalysts for electrochemical CO2 reduction (CO2RR). Jialang Li’s thesis ([86]) demonstrated that nitrogen doping lowers the energy barrier for CO2 reduction, enhancing catalytic activity. In my study, both Vulcan XC 72-R and CIC-85 were investigated. Untreated carbon black (Vulcan XC 72-R) and CIC-85 were found to be inactive for CO2RR. Acid treatment increased the surface oxygen content but did not significantly enhance catalytic activity. However, when acid-treated Vulcan car- bon or CIC-85 was subjected to high-temperature ammonia treatment, substantial nitrogen doping was achieved, as confirmed by advanced surface characterization techniques. My results show that increased oxygen content from acid treatment facilitated greater nitrogen incorporation during ammonia doping, significantly improving CO2RR activity and selectivity. These findings highlight the role of oxygen content in enabling higher nitrogen doping and improving performance for CO2 reduction. These results contribute to both theoretical and experimental advancements in the development of catalysts for sustainable energy applications.

description: The electromagnetic form factors of the proton and the neutron in the timelike region are investigated. Electron-positron annihilation into antinucleon-nucleon ($\bar NN$) pairs is treated in distorted wave Born approximation, including the final-state interaction in the $\bar NN$ system. The latter is obtained by a Lippmann-Schwinger equation for $\bar{N}N$ potentials derived within SU(3) chiral effective field theory. By fitting to the phase shifts and (differential) cross section data, a high quality description is achieved. With these amplitudes, the oscillations of the electromagnetic form factors of the proton and the neutron are studied. It is found that each of them can be described by two fractional oscillators. One is characterized as \lq overdamped' and dominates near the threshold, while the other is \lq underdamped' and plays an important role in the high-energy region. These two oscillators are essential to understand the distributions of polarized electric charges induced by hard photons for the nucleons.

description: Our current understanding of the Universe depends on the interplay of several distinct "matter" components, which interact mainly through gravity, and electromagnetic radiation. The nature of the different components, and possible interactions, tends to be based on the notion of coupled perfect fluids (or scalar fields). This approach is somewhat naive, especially if one wants to be able to consider issues involving heat flow, dissipative mechanisms, or Bose-Einstein condensation of dark matter. We argue that a more natural starting point would be the multi-purpose variational relativistic multi-fluid system that has so far mainly been applied to neutron star astrophysics. As an illustration of the fundamental principles involved, we develop the formalism for determining the non-linear cosmological solutions to the Einstein equations for a general relativistic two-fluid model for a coupled system of matter (non-zero rest mass) and "radiation" (zero rest mass). The two fluids are allowed to interpenetrate and exhibit a relative flow with respect to each other, implying, in general, an anisotropic Universe. We use initial conditions such that the massless fluid flux dominates early on so that the situation is effectively that of a single fluid and one has the usual Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetime. We find that there is a Bianchi I transition epoch out of which the matter flux dominates. The situation is then effectively that of a single fluid and the spacetime evolves towards the FLRW form. Such a transition opens up the possibility of imprinting observable consequences at the specific scale corresponding to the transition time.

description: Non-conventional seed oils are being considered novelty foods due to the unique properties of their chemical constituents. Numerous such seed oils serve as nutritional and functional supplements, making them a point of interest for scholars. Bitter gourd (Momordica charantia L.) seed oil (BGSO) has been widely used in folk medicine worldwide for the treatment of different pathologies, such as diabetes, cancer, and several inflammatory diseases. Therefore, its nutritional and medicinal value has been extensively studied. Considering the potential use of BGSO, it is imperative to have a comprehensive understanding of this product to develop and use its biologically active ingredients in innovative food and pharmaceutical products. An extensive understanding of BGSO would also help improve the economic feasibility of the bitter gourd seed processing industry and help prevent environmental pollution associated with the raw waste produced during the processing of bitter gourd seeds. This review addresses the potential uses of BGSO in terms of food and pharmaceuticals industry perspectives and comprehensively summarizes the oil extraction process, chemical composition, biological activity, and the application prospects of BGSO in clinical medicine.

description: We present the results of the computation of the third order corrections to the ground state energy of the diluted polarized gas of nonrelativistic spin $1/2$ fermions interacting through a spin-independent repulsive two-body potential. The corrections are computed within the effective field theory approach which does not require specifying the interaction potential explicitly but only to characterize it by only a few parameters - the scattering lengths $a_0$, $a_1,\dots$ and effective radii $r_0,\dots$ - measurable in low energy fermion-fermion elastic scattering. The corrections are computed semi-analytically, that is are expressed in terms of two functions of the system's polarization. The functions are given by the integrals which can be easily evaluated using the Mathematica built-in routines for numerical integration.

description: Faced with the challenges of climate change caused by rising greenhouse gas emissions, society is turning to clean energy alternatives. Two key methods being considered are carbon capture, utilization, and storage (CCUS) and geothermal energy. Currently, researchers are focusing on combining these two technologies and this study provides a novel cycle method to integrate CO2 sequestration with geothermal energy production. In the first study, a single well cyclic CO2 injection and hot water production in the Basal Cambrian Sandstone Unit (BCSU), Canada is studied. In the second study, by using cyclic operation, multiple wells with various working modes and operation types are applied in the BCSU for combining CO2 sequestration with geothermal energy production. The third study involves water co-injection with CO2 in both cyclic and continuous modes, aiming to integrate CO2 storage with geothermal energy extraction in the BCSU. In the last study, economic analysis is applied to evaluate the profitability of the designed cyclic and continuous cases with various injection fluid combinations (CO2 and water) in the BCSU. First, the results indicate that in a single well scenario, the designed cyclic system can achieve both CO2 storage and geothermal energy extraction successfully, though the injected CO2 is partially produced along with hot water during the production period due to its high mobility and proximity to the well. Second, the designed multi-well cyclic operation can not only combine CO2 storage with geothermal energy production but achieve net zero emission CO2 storage process during the operation. Third, compared with pure CO2 injection, water injection not only enhances CO2 storage percent significantly with cyclic techniques, but can help achieve net-zero emission cyclic CO2 storage system with geothermal energy production. Fourth, pure geothermal energy production in the BCSU is generally unprofitable, but integrating CO2 injection by using cyclic method can make a satisfactory profit due to successfully sequestering a certain amount of CO2 in the target formation under the positive carbon credit policy. This study evaluates the feasibility of using novel cyclic method to integrate CO2 sequestration with geothermal energy production in the specific formation, which makes contributions for both CCUS and geothermal energy towards carbon neutrality society.

description: We study some properties of the dark degeneracy, which is the fact that what we measure in gravitational experiments is the energy momentum tensor of the total dark sector, and any split into components (as in dark matter and dark energy) is arbitrary. In fact, just one dark fluid is necessary to obtain exactly the same cosmological and astrophysical phenomenology as the LCDM model. We work explicitly the first order perturbation theory and show that beyond the linear order the dark degeneracy is preserved under some general assumptions. Then, we construct the dark fluid from a collection of interacting fluids. Finally, we try to break the degeneracy with a general class of couplings to baryonic matter. Nonetheless, we show that these interactions can also be understood in the context of the LCDM model as between dark matter and baryons. For this last investigation we choose two independent parameterizations for the interactions, one inspired in electromagnetism and the other in Chameleon theories. Then, we constrain them with a joint analysis of CMB and Supernovae observational data.

Critical care medicine

description: Hand-held vital microscopes (HVMs) were introduced to observe sublingual microcirculatory alterations at the bedside in different shock states in critically ill patients. This consensus aims to provide clinicians with guidelines for practical use and interpretation of the sublingual microcirculation. Furthermore, it aims to promote the integration of routine application of HVM microcirculatory monitoring in conventional hemodynamic monitoring of systemic hemodynamic variables. METHODS: In accordance with the Delphi method we organized three international expert meetings to discuss the various aspects of the technology, physiology, measurements, and clinical utility of HVM sublingual microcirculatory monitoring to formulate this consensus document. A task force from the Cardiovascular Dynamics Section of the European Society of Intensive Care Medicine (with endorsement of its Executive Committee) created this consensus as an update of a previous consensus in 2007. We classified consensus statements as definitions, requirements, and/or recommendations, with a minimum requirement of 80% agreement of all participants. RESULTS: In this consensus the nature of microcirculatory alterations is described. The nature of variables, which can be extracted from analysis of microcirculatory images, is presented and the needed dataset of variables to identify microcirculatory alterations is defined. Practical aspects of sublingual HVM measurements and the nature of artifacts are described. Eleven statements were formulated that pertained to image acquisitions and quality statements. Fourteen statements addressed the analysis of the images, and 13 statements are related to future developments. CONCLUSION: This consensus describes 25 statements regarding the acquisition and interpretation of microcirculatory images needed to guide the assessment of the microcirculation in critically ill patients.
Bayesian Variable Selection in a Million Dimensions

description: Bayesian variable selection is a powerful tool for data analysis, as it offers a principled method for variable selection that accounts for prior information and uncertainty. However, wider adoption of Bayesian variable selection has been hampered by computational challenges, especially in difficult regimes with a large number of covariates P or non-conjugate likelihoods. To scale to the large P regime we introduce an efficient MCMC scheme whose cost per iteration is sublinear in P. In addition we show how this scheme can be extended to generalized linear models for count data, which are prevalent in biology, ecology, economics, and beyond. In particular we design efficient algorithms for variable selection in binomial and negative binomial regression, which includes logistic regression as a special case. In experiments we demonstrate the effectiveness of our methods, including on cancer and maize genomic data.

Is there a flatness problem in classical cosmology?

description: I briefly review the flatness problem within the context of classical cosmology and examine some of the debate in the literature with regard to its definition and even the question whether it exists. I then present some new calculations for cosmological models which will collapse in the future; together with previous work by others for models which will expand forever, this allows one to examine the flatness problem quantitatively for all cosmological models. This leads to the conclusion that the flatness problem does not exist, not only for the cosmological models corresponding to the currently popular values of lambda_0 and Omega_0 but indeed for all Friedmann-Lemaître models.

description: We study the Kähler-Einstein manifolds which admits a holomorphic isometry into either the generalized Burns-Simanca manifold $(\tilde {\mathbb C}^n, g_S)$ or the Eguchi-Hanson manifold $(\tilde {\mathbb C}^2, g_{EH})$.

title: Enhanced Oil Recovery from Shale Reservoirs by Huff and Puff Carbon Dioxide and Hydrogen Injection, Safe Permanent Storage of Carbon Dioxide, Temporary Storage of Hydrogen and Life Cycle Assessment: A Contribution to “Net Zero” Emissions

description: Oil production from shale reservoirs has gained attention particularly since the early 2000’s. Oil recovery factors from multi-stage hydraulically fractured horizontal wells have generally been reported to range between 5 and 10% during primary production. This thesis shows that oil recoveries can be significantly improved by conducting huff ‘n’ puff gas injection in shale reservoirs performing under geologic containment, i.e., reservoirs where hydrocarbon fluids are in an inverted position vis-à-vis gravity within the same layer(s) in a given structure. In this research, huff ‘n’ puff CO2, H2, and flue gas injection are investigated using reservoir simulation leading to the following original contributions applicable to shale petroleum reservoirs: (1) a significant increase in oil recovery, (2) safe storage of CO2 on a permanent basis, (3) safe storage of H2 on a temporary basis, and (4) safe storage of flue gas on a permanent basis. In addition, an original multiple sweet spot detection method is developed using a combination of machine learning (ML) and modified Picket plots. All these findings contribute to a possible future with net-zero emissions. The proposed methodology calls for the following procedure (using CO2 as an example): (1) start huff ’n’ puff CO2 injection after the well goes on oil production for 2 or 3 years; thus, the shale reservoir is essentially undepleted, (2) store CO2 gradually in the shale reservoir during the huff periods, and (3) store CO2 continuously once the huff ’n’ puff project is finalized until reaching the initial reservoir pressure. The simulation model includes a history match period with actual production data from a pilot horizontal well of the Eagle Ford Shale in Texas, and forecast periods with huff ’n’ puff CO2, H2, and flue gas injection. The initial reservoir pressure is never exceeded during the life of the project as a safeguard against possible leaks stemming from the creation of new fractures or reactivation of faults. The inclusion of Life Cycle Assessment in the proposed methodology helps to achieve an outcome that is beneficial for improving economics and externalities and consequently helps to balance important pillars of sustainability: society, the environment and economics.
