Authors: Lipp Kelly , Casamassimo Paul , Griffen Ann , Smiley Megann , Bryant Jason , Draper John , Kumar Ashok
Published: December 2021

Objective:

This randomized, prospective, blinded study compared pain in children following dental treatment under general anesthesia (GA) using 1 of 2 established analgesia methods.

Methods:

Patients age 4 to 7 years were randomly assigned to a control group (intravenous [IV] analgesics) or experimental group (IV analgesics and intrapapillary local anesthetic infiltrations) between July 2017 and February 2018. During recovery from surgery, Faces, Legs, Activity, Cry, and Consolability (FLACC) scores were recorded upon regaining consciousness and reassessed every 15 minutes until discharge. Overall pain occurrence (FLACC ≥1) and moderate/severe pain occurrence (FLACC ≥4) were analyzed using mixed effects logistic regression (N = 88).

Results:

The experimental group had a 17% lower overall pain occurrence than the control group (16 vs 33%; p = .02). Moderate/severe pain occurrence between the groups was not significant (9 vs 22%; p = .23). The dental treatment subjects received (number of completed stainless steel crowns, extractions, and/or pulpotomies) did not significantly affect pain occurrence.

Conclusion:

Local anesthesia intrapapillary infiltrations around stainless steel crowns decrease overall pain occurrence but not moderate/severe pain occurrence following dental treatment under GA in pediatric patients.

This paper aims to evaluate the simultaneous elections and view the legal politics of separating the implementation of the simultaneous national and local elections for strengthening democracy in Indonesia. This study uses a normative juridical research method with a statutory and conceptual approaches. The results of the study show that the implementation of simultaneous elections in 2019 provided problems for organizers and voters. One of the suggestions for reforming the elections is to separate local and national elections. The the legal politics objectives of separating the elections consist of two, namely the level of organizers and voters as well as aspects of the election process and the quality of election results. This separation is expected to remove voter pragmatism, and focus more on the vision and mission of the candidates. Political parties will also carry out their functions optimally, be focused, and be able to carry out political education as they should.

Introduction

Unintentional falls are a leading cause of injury-related hospital visits among Canadians, especially seniors. While certain meteorological conditions are suspected risk factors for fall-related injuries, few studies have quantified these associations across a wider range of age groups and with population-based datasets.

Methods

We applied a time-stratified case-crossover study design to characterize associations of highly-spatially-resolved meteorological factors and emergency department (ED) visits for falls, in Ontario, among those aged 5 years and older during the winter months (November to March) between 2011 and 2015. Conditional logistic models were used to estimate the odds ratios (ORs) and their 95% confidence intervals (CIs) for these visits in relation to daily snowfall accumulation, including single-day lags of up to one week before the visit, and daily mean temperature on the day of the visit. Analyses were stratified by age and sex.

Results

We identified 761 853 fall-related ED visits. The odds for these visits was increased for most days up to a week after a snowfall of 0.2 cm or greater (OR = 1.05–1.08) compared to days with no snowfall. This association was strongest among adults aged 30 to 64 years (OR = 1.16–1.19). The OR for fall-related ED visits on cold days (less than −9.4 °C) was reduced by 0.05 relative to days with an average daily temperature of 3.0 °C or higher (OR = 0.95; 95% CI: 0.94, 0.96), and this pattern was evident across all ages. There were no substantive differences in the strength of this association by sex.

Conclusion

Snowfall and warmer winter temperatures were associated with an increased risk of fall-related ED visits during Ontario winters. These findings are relevant for developing falls prevention strategies and ensuring timely treatment.
Programs and interventions promoting health equity in LGBTQ2+ populations in Canada through action on social determinants of health
Authors: Higgins Robert , Hansen Brian , Jackson Beth E. , Shaw Ashley , Lachowsky Nathan J.
Published: December 2021

Sexual and gender minorities (SGM) experience a number of health inequities. That social determinants of health drive these inequities is well-documented, but there is little evidence on the number and types of interventions across Canada that address these determinants for these populations. We conducted an environmental scan of programs in Canada that target SGM, and classified the programs based on their level of intervention (individual/interpersonal, institutional and structural). We found that few programs target women, mid-life adults, Indigenous people or ethnoracial minorities, recent immigrants and refugees, and minority language speakers, and few interventions operate at a structural level.
Effect of hydrogen peroxide solutions on growth of micromycetes Saprolegniaceae on egg membranes of beluga (Huso huso) embryos and on indicators of its embryonic development during incubation

Published: December 2021

The article describes the data of the experimental works on assessing the influence of hydrogen peroxide so-lutions (0.05, 0.10, 0.20, 0.30, 0.40%) in different concentrations on the growth of the micromycetes Saprolegniaceae on egg membranes of beluga embryos and its embryonic development. In conditions of increasing intensification of aquacultures there is an acute problem regarding to the shortage of approved drugs for treating a common disease in fish farming - saprolegniosis. This disease is caused by species of different genus, the most common of which are the genus Achlya and Saprolegnia belonging to the biological kingdom Chromista (Stramenopila), the Oomycota phylum, the Oomycetes class, the Saprolegniales order, the Saprolegniaceae family. The impact of experimental hydrogen peroxide solutions on the beluga embryonic development and infection with saprolegnial micromycetes was assessed by fish-breeding biological indicators: the number of inseminated oocytes, number of survived embryos and hatched prelarvae, number of embryos infected with the micromycetes Saprolegniaceae and abnormally developing fish. Histological analysis of embryos at different stages of development was also carried out. The experimental works were carried out under production conditions in an incubation apparatus of “Sturgeon” type. The experimental groups were formed in accordance with the experimental solutions’ concentrations. Upon the result of the studies it has been inferred that using a 0.05% hydrogen peroxide solution with a 10-minute-exposure proves effective. This solution sup-pressed growth of micromycetes Saprolegniaceae without any negative impact on the embryonic development. Other experimental solutions had a negative impact on beluga (Huso huso) embryonic development of in most cases, causing the increased mortality and, as a consequence, the increased infection rate.

Published: December 2021

The paper presents the results of research conducted in 2020 on the impact of amateur fishing on the aquatic bioresources of Lake Tsatsa, which is part of the Sarpin Lakes located in the Volgograd region. On the basis of field studies (direct accounting), the number of amateur fishermen who visited the lake, as well as the qualitative and quantitative composition of their catches, was established. According to the data obtained, the total catch of fish by amateur fishermen, as well as the average catch per fisherman, was estimated. The size and weight composition of amateur fishing catches was determined based on the analysis of 2912 fish species. During the observation period 9 fish species were marked as part of amateur fishermen’s catches. The assessment of compliance of aquatic biological resources catch by amateur fishermen with the norms of the current Fishing Regulations was carried out. An assessment of the scale of amateur fishing impact on the aquatic bioresources of Lake Tsatsa is given, according to the analysis of the collected data. The catch of amateur fishermen in 2020 in Lake Tsatsa is amounted to 8.8232 tons, which can

account for up to 15% (about 65-70 tons) of the total stock of commercial fish species in the lake. The forecast values of the production volume for industrial fisheries, for which the total allowable catch (TAC) is established and the species for which the recommended catch is determined, are 5.9 and 18.6 tons, respectively. Out of the forecast volumes amateur fishermen additionally catch fish species for which the total allowable catch (TAC) is established (carp, bream, pike)

in the amount of 2.858 tons, and species for which the recommended catch value is determined as 5.643 tons.
Premature death in dogs with nontraumatic hemoabdomen and splenectomy with benign histopathologic findings
Authors: Millar Stephen L. , Curley Taylor L. , Monnet Eric L. , Zersen Kristin M.
Published: December 2021

OBJECTIVE

To determine whether premature death occurred among dogs with nonmalignant splenic histopathologic findings after splenectomy for nontraumatic hemoabdomen.

ANIMALS

197 dogs with nontraumatic hemoabdomen that underwent splenectomy and histopathologic evaluation between 2005 and 2018.

PROCEDURES

Information was obtained from electronic medical records, dog owners, and referring veterinarians to determine patient characteristics, histopathologic findings, survival information, and cause of death. Dogs were grouped based on histopathological diagnosis and outcome, and median survival times (MSTs) and risk factors for death were determined.

RESULTS

Histopathologic findings indicated malignancy in 144 of the 197 (73.1%) dogs with nontraumatic hemoabdomen. Hemangiosarcoma was diagnosed in 126 dogs (87.5% of those with malignancies and 64.0% of all dogs). Nine of 53 (17%) dogs with nonmalignant histopathologic findings had an adverse outcome and premature death, with an MST of 49 days. Risk factors for this outcome included low plasma total solids concentration, an elevated hemangiosarcoma likelihood prediction score, and a medium or high hemangiosarcoma likelihood prediction score category.

CONCLUSIONS AND CLINICAL RELEVANCE

This study showed that there is a group of dogs with nontraumatic hemoabdomen due to splenic disease that have nonmalignant histopathologic findings after splenectomy, but nonetheless suffer an adverse outcome and die prematurely of a suspected malignancy. Further evaluation of potential at-risk populations may yield detection of otherwise overlooked malignancies.
Single-injection caudal thoracic paravertebral block improves pain control and recovery quality in female dogs undergoing unilateral radical mastectomy: a randomized controlled trial
Authors: Santoro Francesco , Debidda Pasquale , Franci Paolo
Published: December 2021

OBJECTIVE

To test clinical and analgesic effects of a single-injection caudal thoracic paravertebral block (TPVB) after localization of the thoracic paravertebral space with a loss-of-resistance to air injection technique in female dogs undergoing unilateral radical mastectomy.

ANIMALS

14 client-owned dogs.

PROCEDURES

Dogs were premedicated with methadone, anesthetized with propofol and sevoflurane, and randomly assigned to receive a TPVB or no block preoperatively. Rescue analgesia with fentanyl and methadone was provided on the basis of cardiovascular responses during surgery and postoperative pain scores assigned with a validated pain scale. Required dose of rescue opioids; mean end-tidal sevoflurane concentration; episodes of hypotension, bradycardia, and other complications; quality of recovery scores; and postoperative pain scores were compared between groups.

RESULTS

Median intraoperative fentanyl doses were 0 µg/kg (range, 0 to 2 µg/kg) and 4 µg/kg (range, 2 to 6 µg/kg) for the TPVB and control groups, respectively. Median postoperative methadone doses were 0 mg/kg (range, 0 to 0.2 mg/kg) and 0.6 mg/kg (range, 0.4 to 0.6 mg/kg) for the TPVB and control groups, respectively. Recovery scores and pain scores assigned at the time of and 1 hour after extubation were significantly lower in the TPVB group than in the control group.

CONCLUSIONS AND CLINICAL RELEVANCE

A single-injection caudal TPVB improved pain control and recovery quality in female dogs undergoing unilateral radical mastectomy. Because the TPVB involves only a single injection, does not take long to perform, and requires only readily available low-cost equipment, the technique may be a valuable option in both referral and first-opinion practice.

Authors: Jihad Ghaith H.
Published: December 2021

In this paper, ferric oxide nanoparticles) Fe2O3 NPs( were synthesized directly on a quartz substrate in vacuum by pulse laser deposition technique using Nd:YAG laser at different energies (171, 201,363 mJ/pulse). The slides were then heated to 700o C for 1 hour. The structural, optical, morphological, and electrical properties were studied. The optical properties indicated that the prepared thin films have an energy gap ranging from 2.28 to 2.04 eV. The XRD results showed no lattice impurities for other iron oxide phases, confirming that all particles were transformed into the α-Fe2O3 phase during the heating process. The AFM results indicated the dependence of nanoparticles size on the laser energy. As the laser energy increased, the average grain size increased from 72.6 nm to 79.02 nm. Hall effect measurement indicated that the film was an n-type semiconductor.

Przyczynek do dziejów działalności kapeli bernardyńskiej w Budsławiu
Authors: Godek Andrzej Edward
Published: December 2021

Kultura muzyczna oo. Bernardynów stanowi ciągle zagadnienie nowe w polskich badaniach muzykologicznych. W większości swoich klasztorów wykonywali oni w XVIII i XIX w. repertuar jednogłosowy, a niekiedy również wielogłosowy oparty na równoległych tercjach i sekstach (tzw. śpiewy pseudochorałowe). Na tym tle wyróżnia się więc klasztor w Budsławiu (obecna Białoruś), w którym w 1756 r. Barbara Skorulska ufundowała kapelę muzyczną. Zespół działał na zasadzie bursy muzycznej, a jego liczebność w różnych latach wynosiła pomiędzy 12 a 20 uczniów-muzyków wywodzących się z okolicznych ubogich rodzin szlacheckich. Jest to jednocześnie unikalny jak dotychczas przykład takiej formy muzykowania w klasztorach bernardyńskich.
Obrzęd konsekracji dziewic i sakrament małżeństwa – różne, a jednak bliskie rzeczywistości. Analiza syntetyczna

Published: December 2021

Sakrament małżeństwa i obrzęd konsekracji dziewic to celebracje należące do dwóch światów,  które wydawać się by mogło nie mają punków stycznych. Sama konsekracja dziewic jawi się jako coś starożytnego i egzotycznego jednocześnie, a zainteresowanie jej znaczeniem jest nadal nikłe. Niniejszy artykuł to syntetyczne przedstawienie badań, jakie zakończyły się w kwietniu 2021 r.,  czego efektem jest praca zatytułowana: Nupcjalny charakter sakramentu małżeństwa i konsekracji dziewic. Studium analityczno – porównawcze. Dostrzeżenie owej oblubieńczości badanych obrzędów, tak w całości, jak w ich poszczególnych elementach, przy jednoczesnym komentarzu dokumentów Stolicy Apostolskiej oraz Ojców Kościoła, dobitnie przemawia za tym, że te rzeczywistości są sobie bardzo bliskie, a nawet wzajemnie się uzupełniają.

Słowa kluczowe: sakrament małżeństwa, obrzęd konsekracji dziewic, nupcjalność, przymierze, oblubieńczość.

Enhancing the Inhomogeneonus Photodynamics of Canonical Bacteriophytochrome

Published: December 2021

The ability of phytochromes to act as photoswitches in plants and microorganisms depends on interactions between a bilin-like chromophore and a protein. The interconversion occurs between the spectrally distinct red (Pr) and far-red (Pfr) conformers. This conformational change is triggered by the photoisomerization of the chromophore D-ring pyrrole. In this study, as a representative example of a phytochrome-bilin system, we take biliverdin IXα (BV) bound to bacteriophytochrome (BphP) from Deinococcus radiodurans. In the absence of light, we use an enhanced sampling molecular dynamics (MD) method to overcome the photoisomerization energy barrier. We find that the calculated free energy (FE) barriers between essential metastable states agree with spectroscopic results. We show that the enhanced dynamics of the BV chromophore in BphP triggers nanometer-scale conformational movements that propagate by two experimentally determined signal transduction pathways. Most importantly, we describe how the metastable states enable a thermal transition known as the dark reversion between Pfr and Pr, through a previously unknown intermediate state of Pfr. Here, for the first time, the heterogeneity of temperature-dependent Pfr states is presented at the atomistic level. This work paves a way toward understanding the complete mechanism of the photoisomerization of a bilin-like chromophore in phytochromes.
A Complementary Silicon Quantum Dot-Enzyme Platform for Selective Detection of Nitroaromatics Compounds
Authors: Milburn Leanne , Robidillo Christopher Jay , Dalangin Rochelin , Veinot Jonathan
Published: December 2021

To address the issue of poor selectivity in nanotechnology-driven, portable nitroaromatics sensors, we have coupled a ratiometric photoluminescence sensor based on silicon quantum dots and fluorescent proteins with a colorimetric enzyme-based sensor. Together, the sensors allow differentiation of nitroaromatic compounds – specifically, distinguishing acetylcholinergic nerve agents from the explosive compounds explored herein. The combined system can detect 2,4,6-trinitrotoluene, 2,4-dinitrotoluene and 4-nitrophenol with micromolar detection limits and affords subsequent differentiation from the nitro-containing nerve agent paraoxon. This demonstrates the advantage of merging elements of materials chemistry and biochemistry to devise customized sensors which can accurately identify hazardous chemical species.
Cuckoo male bumblebees perform slower and longer flower visits than free-living male and worker bumblebees
Authors: Fisogni Alessandro , Bogo Gherardo , Massol François , Bortolotti Laura , Galloni Marta
Published: December 2021

Cuckoo bumblebees are a monophyletic group within the genus Bombus and social parasites of free-living bumblebees, upon which they rely to rear their offspring. Cuckoo bumblebees lack the worker caste and visit flowers primarily for their own sustenance and do not collect pollen. Although different flower-visiting behaviours can be expected between cuckoo and free-living bumblebees due to different biological constraints, no study has yet quantified such differences. Here, we provide the first empirical evidence of different flower-visiting behaviours between cuckoo and free-living bumblebees. We recorded the flower-visiting behaviour of 350 individual bumblebees over two years in a wild population of the entomophilous plant Gentiana lutea, of which they are among the main pollinators. In cuckoo bumblebees (28.9% of the total), we only found males, while we found both workers and males in free-living bumblebees. Cuckoo bumblebees visited significantly more flowers for longer time periods than both free-living bumblebee workers and males within whorls, while differences at the whole-plant level were less marked. Free-living bumblebee males visited more flowers and performed slightly longer flower visits than workers. Behavioural differences between cuckoo male bumblebees and free-living bumblebee workers are likely related to different foraging needs, while differences between cuckoo and free-living bumblebee males may be caused by differences in colony development and a delayed mating period of free-living bumblebees. The longer visits made by cuckoo male bumblebees will likely negatively affect plant reproductive success through increased within-plant pollen flow.

Published: December 2021

The issues of well-posedness of linear inverse coefficient problems for multi-term equations in Banach spaces with fractional Riemann – Liouville derivatives and with bounded operators at them are considered. Well-posedness criteria are obtained both for the equation resolved with respect to the highest fractional derivative, and in the case of a degenerate operator at the highest derivative in the equation. Two essentially different cases are investigated in the degenerate problem: when the fractional part of the order of the second-oldest derivative is equal to or different from the fractional part of the order of the highest fractional derivative. Abstract results are applied in the study of inverse problems for partial differential equations with polynomials from a self-adjoint elliptic differential operator with respect to spatial variables and with Riemann – Liouville derivatives in time.

Here, amphiphilic molybdenum disulfide (KH550-MoS2) nanosheets were synthesized using a hydrothermal approach. The physicochemical properties and potential EOR of ultra-low concentration KH550-MoS2 nanofluids were systematically investigated under reservoir conditions at Changqing Oilfield (China) (temperature~55℃ and salinity~7.8×104 mg/L). Interfacial tension (IFT), wettability change, and emulsion stability were measured to evaluate the physicochemical properties of the KH550-MoS2 nanofluids. The results showed that ultra-low concentration of KH550-MoS2 nanofluid (50 mg/L) could decrease IFT to 2.6 mN/m, change the contact angle (CTA) from 131.2° to 51.7° and significantly enhance emulsion stability. Core flooding experiments were conducted to determine the dynamic adsorption loss law and the oil displacement efficiency of KH550-MoS2 nanofluid. The results indicated that the ratio of cumulative produced KH550-MoS2 nanosheets to the total injected KH550-MoS2 nanosheets (CNR) reached 91.5% during flooding in low permeability reservoirs. Moreover, ultra-low concentration KH550-MoS2 nanofluid can increase the oil displacement efficiency by 14% after water driven. This study shows the physicochemical properties of the KH550-MoS2 amphiphilic nanofluid and offers a novel high- efficiency amphiphilic nanoﬂuid for EOR

Published: December 2021

Shallow heavy oil in Indonesia is one of undeveloped resources with high potential that require breakthrough in unconventional production technology. Iliran High Field, located in South Sumatera, has this potential and been conducting several production method for optimum production since 2011. The depth of the potential formation is 10 – 500 ft with range of viscosity 200 – 600 cp at reservoir temperature. Production methods including steam injection, radial jetting, chemical injection and variety in borehole size have resulted in low production rate. Major technical challenge is the reservoir have naturally very low reservoir pressure thus limiting possibility for further stimulation. Finding the production solution for this field would require technology that is not limited by pressure, which ultimately leads Medco to explore the opportunity of oil mining. Oil mining has been done for producing the shallow depth oil sand and has proven effective with high recovery factor. Since this is novel in Indonesia, preliminary studies were conducted. The studies conducted in laboratory use conventional core with the objective of selecting optimum extraction method and parameters. High recovery factor of > 94% was achieved by means of selecting solvent extraction method and parameters such as solvent type, ore to solvent ratio and ore size. The high recovery factor result concluded that oil-mining method is highly feasible and interesting for development. For the next step of this journey, larger scale of study is planned which includes real excavation result and further study of economic analysis. The positive result could be the solution for optimally produce the shallow heavy oil potential.

Published: December 2021

Tunu is a mature giant gas and condensate field locate in Swamp Area on Mahakam Delta, East Kalimantan, Indonesia. The field has been in developed for more than 40 years and considered as a mature field. As mature field, finding an economic well has become more challenging nowadays. The deeper zone of Tunu (TMZ) has no longer been considered profitable to be produced and the focus is shifted more on the producing widespread shallow gas pocket located in the much shallower zone of Tunu (TSZ). Facing the challenge of marginal reserves in the mature field, Pertamina Hulu Mahakam (PHM) take two approaches of reducing well cost thus increase well economics, improving drilling efficiency and alternative drilling means. Continues improvement on drilling efficiency by batch drilling, maxi drill, maximizing offline activities and industrialization of one phase well architecture has significantly squeezed the well duration. The last achievement is completing shallow well in 2.125 days from average of 6.5 days in period of 2017-2019. Utilization of Swamp Barge Drilling Rig on swamp area had been started from the beginning of the field development in 1980. Having both lighter and smaller drilling unit as alternative drilling means will give opportunity of reducing daily drilling rate. Hydraulic Workover Unit (HWU) comes as the best alternative drilling means for swamp area. In addition, fewer and smaller footprint equipment requires smaller barges with purpose of less civil works to dredge the river and preparing well location. Drilling with HWU project has been implemented at Tunu area with 5 wells has been completed successfully and safely. HWU drilling concept considered as proven alternative drilling means for the future of shallow wells development.

Published: December 2021

BH field is one of the Globigerina limestone gas reservoir that exhibits strong seismic direct hydrocarbon indicator (DHI). This field is a 4-way dip faulted closure with Globigerina limestone as the main reservoir objective. The field was discovered back in 2011 by BH-1 exploration well and successfully penetrated about 350ft gross gas pay. BH-1 well was plugged and abandoned as Pliocene Globigerina limestone Mundu-Selorejo sequence gas discoveries. The laboratory analysis of sampled gas consists of 97.8% of CH4 and indicating a biogenic type of gas. This is the only exploration well drilled in this field and located on the crest of the structure. Seismic analysis both qualitative and quantitative, are common tools in delineating and characterizing reservoir. These methods usually make use of seismic data and well log collaboratively in the quest to reveal reservoir features internally. The lack of appraisal well in the area of study made the reservoir characterization process must be carried out thoroughly, incorporating several seismic datasets, both PSTM and PSDM, seismic gathers and stacks. Bounded by appraisal well limitation, this research looks into Gassmann's fluid substitution modeling, seismic forward modeling to confirm the DHI flat spot presence in the seismic, as well as seismic AVO analysis. Meanwhile, for quantitative analysis, model-based seismic post-stack inversion and simultaneous seismic pre-stack inversion were conducted in order to delineate the distribution of Globigerina limestone gas reservoir in BH Field. Through comprehensive analyses of qualitative and quantitative methods, this research may answer the challenge on how to intensively utilize seismic data to compensate the lack of appraisal well data in order to keep delivering a proper subsurface reservoir delineation.
The Power of Predictive Analytics in Oil Field Development: Integrating Machine Learning with Reservoir Hydrocarbon Data to Enable Enhanced Oil Recovery of Hugin Formation within the Theta Vest Structure
Authors: Hardanto L. T.
Published: December 2021

Machine learning is an algorithm based on pattern recognition and the concept that computers can learn without being programmed to perform specific tasks. Machine learning applications that are commonly used in the oil and gas companies are petrophysical estimation and well log classification, seismic structural identification, production forecasting, and artificial intelligence tasks. The goal of this study is to integrate machine learning workflows to evaluate how reservoir hydrocarbon distribution can help prospecting, field development, and production optimization, especially 4D seismic studies. Also to observe the ﬂuid ﬂow and to detect bypassed oil pockets changes during the production. The workflow consists of three phases: planning, execution, and delivery. The first phase consists of collecting and preprocessing wells, seismic and interpretation data. Once the plan is considered satisfactory, it will be followed by the execution that is started with data cleaning, processing, classification, and data validation. Machine learning methods are then deployed to build an electrofacies and reservoir distribution model for the Hugin Formation using Multi-Resolution Graph-Based Clustering (MRGC). After these models reach a satisfactory level, seismic attribute analysis is performed using Principal Component Analysis (PCA) and Democratic Neural Network Association (DNNA) to create a facies probability volume. The last step in this phase is to detect geobodies of oil sand and propose an infill well or injection strategy to enable the enhancement of the oil recovery. Once the machine learning results are satisfying, tthe status of the workflow will change from execution to the delivery phase to create the final project presentation. In our study, DNNA has demonstrated excellent prediction and facies classification to image a large volume encompassing some wellbores, changes in the fluid flow during production between baseline, and monitoring seismic surveys with a good Matthews correlation coefficient of 0.849554. It allows the operator to observe the dynamic processes in and around the reservoir to help the placement of infill wells more effectively, increas development and production success, reduce risk when following proposed infill wells. The integration of machine learning can also improve the understanding of hydrocarbons in the field. It shapes E&P business strategies in a way that may increase profit revenues, such as enhanced oil recovery of an effective and efficient infill well and optimizing an injection strategy.
