Emerging infectious diseases are a major threat to biodiversity and an important public health issue. West Nile virus (WNV) is an emerging vector-borne zoonotic arbovirus that is currently broadening its distribution in Europe. The evidence of WNV circulating in resident and migratory species has implications for both animal and public health, and should therefore be studied in depth. An integrated surveillance program, namely in birds, is essential for reducing the risk of infection in human populations within the One Health principles. In the present study, wild birds admitted to wildlife rehabilitation centres in Portugal were sampled. Two-hundred and eight blood samples were assayed serologically to antibodies to WNV, by using a commercial ELISA kit. An overall seroprevalence of 19.6% (95% confidence interval [CI]: 13.7-26.7%) was observed. Antibodies to WNV were detected in 13 (35.1%) different species of wild birds. Accipitriformes (26.7%; 95% CI: 18.5-36.2%) and Strigiformes (26.7%; 95% CI: 14.6-42.0%) were the orders with the highest seroprevalence recorded. There were no statistically significant differences (p = 0.725) between the geographical regions (NUTS II) studied, but statistically significant difference (p = 0.017) was found between gender (male: 34.4%; female: 4.8%). A higher seroprevalence was found in adults (32.1%) compared to juvenile birds (9.3%) (p = 0.014), and age was considered a risk factor to WNV infection in wild birds (odds ratio 1.4; 95% CI: 0.5–4.0). More epidemiological studies are needed in Portugal, since the actual spread of the WNV throughout the country is unknown.

The diversity of plant species found in the Temedak customary forest is relatively high but residents should not use it freely. Residents are prohibited from cutting or taking wood from the forest, they can only take fruit, rattan and bamboo for their own consumption and must have the permission of local traditional leaders. The higher the diversity of plants found in the Temedak customary forest, the higher the threat from outside. This is evidenced by the theft of wood, bamboo and other plants in the Temedak customary forest carried out by irresponsible people. For this reason, conservation attitude profile data is needed to identify categories of each indicator of students' conservation attitudes in protecting and overcoming surrounding biodiversity problems. This research uses quantitative descriptive method. Research participants included housewives, village shamans, local or community leaders. The instruments used are in the form of field notes of interview guidelines and conservation attitude questionnaires. The questionnaire was in the form of 38 statements tested to XI MIPA SMA students consisting of 40 respondents. Based on the results of the study, it was found that the Temedak customary forest has endemic plant species, namely pacat wood (Harpullia arborea) and carrion flowers namely Amorphophallus gigas. There are 57 types of plants that generally used by the people of Keluru Village such as foodstuffs, buildings, medicins, wicker, local technology and art, as well as for the benefit or complement of traditional ceremonies. The results of obtaining student conservation attitudes from 40 respondents showed differences in each indicator.

Background:
The comparative effectiveness of decompression plus lumbar facet arthroplasty versus decompression plus instrumented lumbar spinal fusion in patients with lumbar spinal stenosis and grade-I degenerative spondylolisthesis is unknown.

Methods:
In this randomized, controlled, Food and Drug Administration Investigational Device Exemption trial, we assigned patients who had single-level lumbar spinal stenosis and grade-I degenerative spondylolisthesis to undergo decompression plus lumbar facet arthroplasty (arthroplasty group) or decompression plus fusion (fusion group). The primary outcome was a predetermined composite clinical success score. Secondary outcomes included the Oswestry Disability Index (ODI), visual analog scale (VAS) back and leg pain, Zurich Claudication Questionnaire (ZCQ), Short Form (SF)-12, radiographic parameters, surgical variables, and complications.

Results:
A total of 321 adult patients were randomized in a 2:1 fashion, with 219 patients assigned to undergo facet arthroplasty and 102 patients assigned to undergo fusion. Of these, 113 patients (51.6%) in the arthroplasty group and 47 (46.1%) in the fusion group who had either reached 24 months of postoperative follow-up or were deemed early clinical failures were included in the primary outcome analysis. The arthroplasty group had a higher proportion of patients who achieved composite clinical success than did the fusion group (73.5% versus 25.5%; p < 0.001), equating to a between-group difference of 47.9% (95% confidence interval, 33.0% to 62.8%). The arthroplasty group outperformed the fusion group in most patient-reported outcome measures (including the ODI, VAS back pain, and all ZCQ component scores) at 24 months postoperatively. There were no significant differences between groups in surgical variables or complications, except that the fusion group had a higher rate of developing symptomatic adjacent segment degeneration.

Conclusions:
Among patients with lumbar spinal stenosis and grade-I degenerative spondylolisthesis, lumbar facet arthroplasty was associated with a higher rate of composite clinical success than fusion was at 24 months postoperatively.

Published: May 2024

Abstract
Spontaneous imbibition is of crucial importance in the residual oil extraction from strongly heterogeneous reservoirs, such as in the naturally fractured formations. The relative importance of the two major mechanisms, IFT reduction and wettability alteration, in the early stages of spontaneous imbibition constitutes the focus of this work. In this study, two selected surfactants, SS885 and GS2, had opposite strengths and weaknesses in the two mechanisms, as was confirmed with spinning drop and pendant drop IFT measurements and static contact angle measurements. Four Indiana limestone core plugs of two permeability levels, ~30 mD and ~150 mD, were divided into two groups. The effect of oil-aging was confirmed with NMR T2 distribution changes. After oil-aging, the two plugs in each group were soaked in SS885 and GS2 solutions, respectively. The oil recovery was recorded and compared to support the understanding of the relative contribution in the early stages of spontaneous imbibition in different permeability conditions. Results showed that wettability alteration has more contribution to the oil recovery than IFT reduction in the early stages of the spontaneous imbibition regardless of the permeability difference in the range of 24~167 mD. A higher permeability promotes a faster oil recovery when only IFT reduction occurs. A lower permeability promotes a faster oil recovery when the rock is altered towards water-wet conditions.

Summary
The objective of this study is to develop an explainable data-driven method using five different methods, namely: Recurrent Neural Network (RNN), XGBoost, GMDH, CatBoost and GP to create a model using a multi-dimensional dataset with over 700 rows of data for predicting MMP. In this work, we applied various AI methods (three black box algorithms and two White-box algorithms) to train a model using a multi-dimensional dataset with over 700 rows of data. Moreover, two robust correlations will be developed that can be used for a wide range of parameters. The dataset has 20 variables, and five subsets (labelled SET1 to SET5) were used as input parameters to develop models. The subsets were selected using a feature importance analysis (similar to Gray’s theorem). Among the multiple inputs tested, the model trained with SET1 and SET5 input parameters (including mole fraction of different hydrocarbon and nonhydrocarbon components and reservoir temperature) resulted in the most accurate estimations of MMP (R2 = 0.99). To further improve the explainability of the model, sensitivity and shapely values analyses were conducted on the developed models, and the impact of each individual feature on the output (MMP) was explained. Temperature, volatile/intermediate, and nonhydrocarbon components are the most influential parameters depending on the subset of parameters chosen; moreover, the models developed in this work performed considerably better (25-40% more accurately) compared with three well-known empirical models from the literature. The result of the current study is repeatable; the developed correlations can be readily applied in other scenarios within the scope of the parameters used to develop the models. The vast range of features in the dataset makes it suitable to study the effects of different parameters on MMP in conditions representative of CO2-EOR and CCUS.

Abstract
The strategic target and path to peak CO2 emissions and carbon neutrality, which have been initiated by several countries over the last decade, considerably affected whole energy industry especially oil and natural gas fields. The recoverable shale-gas reserves of Sichuan Basin in China is beyond 1.0×1012 m3. Environmental pollution and carbon emission issues caused by diesel-powered operations cannot be ignored. The electrification of upstream operations has been concerned and applied only in production, processing and transportation. Electrification work towards shale gas was still faced with poor economy when large-power operations such as drilling and fracturing are performed. Due to unpredictable developing progress and high energy-consuming operation, power supply and load demand forecast is quite challenging. Existing operations using coal-based power generation negatively affects environmental-social-governance (ESG) initiatives without green renewable energy.
One ESG path to green production and recommended practices towards electrifying recovery were proposed in this paper. Fully electric-powered equipment (2500HHP to 7000HHP pumping units, blending units, manifold etc.) was widely used with 35kV customized power grids. Due to great hydropower in Sichuan Basin, power generation exhibits seasonal fluctuation and focused on peak electricity consumption for civilian use in summer and winter. The hydropower and energy-storage sharing with data centers was applied to deal with seasonal energy supply and fluctuating load especially fracturing operations with great economic advantages. Electrical load variation and power gap between supply and demand were precisely forecasted through machine-learning algorithms under different conditions of drilling and fracturing.
At the end of 2022 shale-gas production in Sichuan Basin has increased to 1.39×1010 m3. Hydropower proportion has accounted for 72% of power consumption for shale-gas development with 19 newly-constructed transformer substations, 1145.7 km of 35kV grids and 1197 MVA of grid capacity. The fully electric-powered operation reached almost 40% of all operating pads. It was estimated that hydrocarbon fuels of 6.1×105 ton were replaced and CO2 emission reduction reached more than 7.7×105 ton so far. The detailed recommended practices and lessons learnt from electrifying shale-gas recovery were guidable for the recovery of other unconventional resources.

Published: May 2024

Abstract
Due to the large water depth and geological structure, a large amount of nature gas hydrate (NGH) and shallow gas are buried in the shallow layer in the deepwater area of the South China Sea. Conventional deepwater oil and gas well design faces the risk of wellhead subsidence and collapse, which led to a greater risk of well construction in the surface layer. By venting shallow gas, optimizing the wellbore structure design, and using a unique surface cementing slurry system, a set of methods for comprehensively dealing with surface NGH and shallow gas has been established. According to the construction operation process, a set of risk disposal plans for dealing with NGH and shallow gas is established. Before drilling, the method of drilling pilot holes is used to release and spray NGH and shallow gas. Considering the influence of NGH decomposition and shallow gas leakage on the soil, the undrained shear strength of the surface soil is converted, and the minimum depth of the surface conductor to meet the bearing capacity of the wellhead is calculated to be 90.8 m. During the 0.6604 m holes cementing, the cementing quality is not good due to the existence of NGH and shallow gas. Assuming that there is no cement slurry sealing above the NGH and shallow gas layers, the penetration depth 547 m of the 0.508 m and 0.34 m combined surface casing is confirmed safe. The liquid lightening agent and early strength cement slurry system is used for cementing operation, and the suspected NGH layer and shallow gas layer are sealed to ensure the cementing quality. During the actual drilling operation, gas overflow occurred in the pilot hole, and NGH were formed in the subsea wellhead and the lower diversion cover of the blowout preventer (BOP), which confirmed the existence of NGH and shallow gas. Through a series of optimized design and prevention measures, the construction of the surface layer of Well S was successfully completed. A set of shallow operation methods suitable for ultra-deepwater wells are proposed for the shallow geological disasters in the South China Sea. The method effectively reduces the risk of shallow geological disasters, improves the safety of shallow well construction, and provides rich experience for the construction of such wells.

Published: May 2024

Abstract
Surfactant flooding is a well-known chemical enhanced oil recovery (cEOR) technique. However, surfactant surface chemistry and the associated interactions with rock surfaces are complex and have not been fully investigated. Here, we experimentally investigate the surface chemistry of 15 rock surfaces (10 carbonate and 5 sandstones) upon interaction with different types of surfactants, including cationic, anionic, non-ionic, and zwitterionic surfactants at different concentrations (before, at, and after the critical micelle concentration, CMC). The rock samples were examined using Scanning Electron Microscopy (SEM) to investigate their structure and surface morphology. To understand the interactions at the surfactant-mineral interface and surfactant behavior, the zeta potential measurements of surfactant-brine-rock emulsions were performed, while surface chemical functional groups were identified by Fourier-transform infrared (FTIR) spectroscopy.
The zeta potential results show that both anionic (SDS) and cationic (CTAB) surfactants depict better stability, in carbonates and sandstones, compared to the non-ionic (Triton X-100) and zwitterionic (3- (N, N-Dimethylmyristylammonio) surfactants, which is due to the nature of the charge of each surfactant. Also, the FITR results indicate the existence of different chemical bonds and functional groups at different concentrations for each surfactant type, and the magnitude of these bonds differs as a function of rock type and mineralogy. For instance, the rock samples treated with CTAB cationic surfactant reveal the presence of C-O, Mg-C, and Ca-C groups at all concentrations. However, despite being present at all concentrations, these responses show different magnitudes at different surfactant concentrations. The results of this study provide valuable data set to understand the surfactant surface chemistry interactions with different carbonate and sandstone rock surfaces and thus have direct implications for chemical enhanced oil recovery.

Innovative Strategies for Well Integrity in Offshore Top-Hole Cementing: Laboratory-Validated Success in Shallow Gas Mitigation
Authors: Elahifar Behzad , Ibrahimli Javidan 
Published: May 2024

Abstract
This paper primarily aims to address the pressing issue of shallow gas intrusion and gas channeling during offshore top-hole cementing. We seek to introduce and substantiate two novel approaches using the dual gradient drilling system / Riser-less Mud Recovery (RMR) system, emphasizing their practical application in the laboratory and field effectiveness (on jack-up and Semi-submersible, drill Ship, etc.). We applied two different methods of managed pressure cementing (MPC) with RMR in our study. The first method involved confirming the cement at the seabed and then filling the RMR return line with water up to the rig floor. The return line filled with water up to the rig floor including the air gap allowed us to apply extra pressure on the cement during its curing time. The second method involved closing the Suction module (SMO) valve after detecting the cement at the seabed. This trapped the cement in a closed space and prevented any gas from entering during its dehydration time. We tested both methods in laboratory settings to prove the offshore field result.
This study has provided important results and valuable insights, leading to strong conclusions. In the offshore drilling context, the innovative RMR-based top-hole cementing methods have proven highly effective in addressing shallow gas challenges. The first method, focusing on pressure management, consistently exhibited efficacy during field applications and laboratory testing. It entailed the identification of cement placement behind the surface casing, followed by water infusion into the RMR return line, effectively preventing gas channeling during cement curing. The second method, employing the permanent SMO valve to confine cement, consistently delivered commendable performance across laboratory and field conditions. It effectively prevented gas infiltration or channeling during the critical cement dehydration phase. In summary, these findings underscore the potential of these techniques to enhance gas mitigation during top-hole cementing in offshore drilling significantly. Both approaches, substantiated through field and laboratory validation, make a substantial contribution to the body of knowledge in offshore drilling and reinforcing well integrity. They also have the potential to reduce environmental impact and drilling costs.
This paper introduces innovative solutions to tackle the persistent challenge of shallow gas in offshore drilling. These proposed methods, supported by field data and laboratory validation, provide practical insights and strategies for ensuring cement integrity, thereby contributing significantly to the petroleum industry's knowledge base.
