Published: August 2020

AbstractWe propose a template-matching workflow capable of improving detection sensitivity of a seismic network and demonstrate its performance on the local seismic network comprising Texas Seismological Network installations in West Texas. We use three earthquakes from three clusters as our templates. Template matching is applied to each station independently. Then, SeisComP3 scanloc associator groups the obtained picks into seismic events following moveouts between stations consistent with a velocity model. In comparison to short-term over long-term average detection workflow, the number of “new,” previously undetected events more than doubles. The events detected by the template-matching workflow are registered on a set of stations, thus allowing for their absolute location. Template matching improves local network sensitivity. Among network parameters, station noise conditions appear to have the highest influence on the effectiveness of the workflow.

Authors: MAISSE G. 
Published: August 2020

Une revue d’un certain nombre de travaux portant sur le sperme de salmonidé permet d’en dégager les particularités : l’absence d’acrosome, l’immobilité dans le fluide séminal liée à la présence de l’ion potassium dont la dilution est la première condition de l’activation, la faible durée de la motilité qui est due à l’incapacité de la mitochondrie à compenser rapidement les pertes en ATP, la dépendance vis-à-vis des conditions de milieu (température, pH, oxygène). Ces caractéristiques entraînent un certain nombre de recommandations au niveau de la pratique piscicole, et la mise au point de dilueurs de fécondation, de conservation à court terme et de congélation.

Published: August 2020

Highly porous and stable materials, such as alumina, silica, carbon, zeolite, and bentonite, are well known and have been used as metal ion adsorbents. However, the use of biogenic carbon as adsorbent is relatively rare. The adsorption of copper(II) onto activated carbon extracted from Salcaca zalacca peel was studied. The effect of initial copper concentration, contact time, and a series temperature was studied. Adsorption was carried out in a batch technique. The adsorption equilibrium was reached after 60 minutes of contact time. The adsorption data had a better fitting line for the Langmuir isotherm model. The Langergren and also Ho and Mc Kay equations were used to predict the adsorption kinetics. The adsorption process obeyed a second-order kinetics model. The Thermodynamic parameters were ∆H°= -42.4180 kJ/mol; ∆S°= -0.0843 kJ/mol; ∆G°<0. These values indicated that the adsorption was exothermic and spontaneous. The low ∆G° value revealed that the main mechanism controlling the adsorption process was physisorption.

Curcuminoids are the main component found in many Zingiberaceae family plants. The aim of this study was to characterize curcuminoid and its activity test as an antioxidant and antibacterial. Dryed powder of C. xanthorrhiza (1 kg) was macerated with ethanol for 24 hours at room temperature. Ethanol extract of C. xanthorrhiza was subsequently fractionated with n-hexane and chloroform to take the yellow or orange indicated contain of curcuminoids. Analysis of total phenolic levels was carried out by the Follin-Ciaocalteau method. The isolation of curcuminoid componens from this fraction was carried out by chromatographic method and the structure elucidation was performed by interpretation of spectroscopic data, including UV, IR, 1H and 13C NMR 1D and 2D. The antioxidant activity test used the DPPH (2,2-diphenylpicrylhydrazyl) method, while the antibacterial activity test used Kirby Bauer test diffusion method. The results showed that the curcuminoid fraction yield was 10.06% from ethanol extract C. xanthorrhiza. The total phenolic content of curcuminoids fraction was 745.45 ± 18.5 mg galic acid (GA)/g extract. Curcuminoids fraction was isolated a known compound desmethoxycurcumin (1). The content of demethoxycurcumin (1) in curcuminoid fraction is 20.97 %.The antioxidant activity of curcuminoids fraction showed strongest activity with IC50 24.98 µg/ml. Antibacterial activity against of the four pathogenic bacteria showed medium activity. The study suggests that curcuminoids extract from C. xanthorrhiza rhizome have potential compounds could be suitable for antioxidant and the treatment of various infections caused of microbial.

An experiment was designed to study the effects of curcumin and thyroxine hormone supplementation in the diet to improve the reproductive performance of catfish broodstock by improving egg quality that eventually increases the production of seedlings. Catfish used in this experiment were supplemented with curcumin and thyroxine hormone through their feeds for 12 weeks. The results showed that there was no significant difference (p > 0.05) in the hepatosomatic index (HSI), gonadosomatic index (GSI), percentage of gonad maturity, total cholesterol concentration in the spawned eggs, high density lipoprotein (HDL) concentration in the spawned eggs, fertilization rate of spawned eggs, and hatching rate of fertilized eggs. However, there were significant differences (p < 0.05) in the concentration of vitellogenin in the spawned eggs, egg diameter of the spawned eggs, and the triglycerides contents of spawned eggs. It was concluded that curcumin and thyroxine supplementations of African catfish increased vitellogenin concentrations and diameters of spawned eggs that have great potential to improve the reproductive performance.

Published: August 2020

Background and Objectives:
This study aims to investigate the strength of the association between socioeconomic, maternal and environmental determinants and under-five mortality in Ghana.

Methods:
We utilized data from the 2014 Ghana Demographic and Health Survey, a population-based cross-sectional study, which included 4151 children born alive to women aged 15-49 years. The primary outcome variable was under-five mortality. Descriptive statistics and multivariate logistic regression were applied to assess the relationship and relative association of the independent variables with the outcome variable.

Results:
Children of women with secondary education and above and women within the middle wealth status were 0.593 and 0.886 less likely to experience under five deaths compared to women with no education and women of low wealth status (OR=0.593; 95% CI 1.690 to 2.063; p< 0.01) (OR =0.886; 95% CI 1.48 to 1.63; p<0.01). Women who had their first child between the ages of 20-29 were 0.764 less likely to have children die before age 5 compared to those women who had their first child between the ages of 15-19. (OR= 0.764; 95% CI 0.994 to 1.191; p<0.0l). Children born in households with pit toilets were more likely (OR= 1.51; 95% CI 1.20 to 2.30; p<0.01) to die before age five compared to children born in households with flushed toilet. Women who used borehole/well-water were more likely (OR= 1.686; 95% CI 2.94 to 3.01; p< 0.05) to experience under-five deaths compared to women who used piped water.

Conclusion and Implications for Translation:
This study identified the determinants that significantly predicted under-five deaths and the magnitude of the influence on under-five deaths in Ghana. It accentuates the need for increased maternal education, delayed childbearing age, provision of improved drinking water and toilet facilities to reduce under-five deaths in Ghana.
Canadian Oil Sands Output Cut 1 Million B/D What Could Go Wrong?
Authors: Rassenfoss Stephen 
Published: August 2020

When Matt Fox, chief operating officer for ConocoPhillips, was asked about how the company is managing its 100,000 B/D reduction at its Surmont project, the response was reassuring.
“We’re not doing anything that’s going to take any risk either from a reservoir or wells or facilities perspective. That’s why … in Surmont, we’re going down to a minimum rate, so that we can still provide enough heat and temperature to the steam chambers to keep them intact,” Fox said during a recent call with stock analysts.
To be clear, he is not saying there is no risk. ConocoPhillips and others are using various methods to turn down production that maintain the heat and pressure they spent years creating in reservoirs where pairs of wells are used to inject steam to heat bitumen. Gravity then drains the melted bitumen down to the production well in a process known as steam-assisted gravity drainage (SAGD).
While what they and other companies in the oil sands are doing is commonly described as shutting in wells, they are actually slowing the production from those wells. Some use reduced steam injections in a well pair, alternate cyclic injection among wells, or injections of gas to maintain the pressure.
“It is a good test case,” said Scott Norlin, a research associate at Wood Mackenzie. The geologist who used to work in the oil sands said shutting in wells is not a good description of how they are cutting production.
“It is almost like cooking a turkey for Thanksgiving,” and dinner is delayed, so “you turn the temperature down. You’re not throwing it back in the freezer,” he said.
Future productivity in wells that have been turned down requires maintaining the temperature and pressure at levels high enough to preserve the steam chamber - the area above the injection where the water vapor thins peanut-butter-thick bitumen so it can flow.
Keeping it hot enough to maintain the steam is critical because if it is allowed to condense into liquid form, it will cause a pressure drop which can open the door for serious trouble.
The minimum safe injection level will vary based on factors ranging from a water layer next to the steam chamber to the age of the well.
Years of steam injections warm the rock around the productive zone, slowing cooling if the injections are stopped or reduced. If there is a water zone in contact with the production zone, too little steam may allow an influx of water, which would quench the steam chamber.
“If we cut the steam rate, but keep it high enough to supply the heat loss, and thus maintain the steam temperature (which means pressure), the production rate will go down, but the steam chamber will continue to exist without resaturation,” said S.M. Farouq Ali, a distinguished professor at the University of Houston Cullen College of Engineering.
Technology Focus: Health, Safety, and Environment (August 2020)
Authors: Knode Tom 
Published: August 2020

One year ago, this editorial communicated the exciting progress within the SPE health, safety, and environment (HSE) discipline and shared a preview of the 2020 SPE International Conference on HSE and Sustainability, which was to be held in Bogota, Colombia, in March.
The high-level focus of our discipline’s flagship biennial event is “Generating Pride and Enabling Engagement,” and the 100-person-strong program committee spent months building an excellent balance of papers and speakers. What we did not know at the time was that, shortly before our conference was to start, our industry would find itself coping with a historic drop in oil prices and society would be fighting a global pandemic.
SPE responded by postponing this and other conferences to protect the health and safety of our members. The good news is that the 2020 HSE and Sustainability conference will go ahead at the end of July 2020 as one of the first fully virtual conferences and exhibits offered by the SPE. As you read this edition, its participants will be wrapping up what will undoubtedly have been another successful knowledge-sharing event.
Our industry has had a swift response to the pandemic by deploying mitigation processes several weeks before the World Health Organization even declared it a pandemic. A study from the University of Houston entitled “The Energy Workforce and COVID-19: Data-Driven Policy Recommendations” indicates that the industry has taken appropriate actions. Planning is a key element to managing any emergency, and there will be many lessons learned to share as we recover from this threat. One paper included in this section covers the response to infectious diseases in offshore operations.
A new Safety Leadership Academy, webinars, and other training courses, as well as conferences and regional and local events, can and will serve as the means for development in HSE. In this low-oil-price era, with pressure to reduce costs, it is of the utmost importance that we have engaged and well-informed HSE leaders across the industry.
2019 also saw the arrival of a new strategic initiative - the Gaia Program. It is a nonhierarchical multistakeholder community enabled by SPE and other professional associations with the basic premise of helping ensure oil and gas comes out on the right side of history - valued for its contributions, yet agile and imaginative enough to evolve with changing expectations of its role in society. SPE Live, which can be found on SPE’s LinkedIn page, regularly features Gaia Talks, if you’d like to join and learn more.
This selection of technical papers focuses on all aspects of HSE and sustainability. A library of technical papers can also be found in OnePetro and on the HSENow online publication.
Machine-Learning-Assisted Closed-Loop Reservoir Management Using Echo State Network for Mature Fields under Waterflood
Authors: Deng Lichi , Pan Yuewei 
Published: August 2020

Summary
Closed-loop reservoir management (CLRM) consists of continuous application of history matching and optimization of model-predictive control to maximize production or reservoir net present value (NPV) in any given period. Traditional field-scale implementation of CLRM by using a large number of reservoir models, in particular when uncertainty is accounted for, is computationally impractical. This presented machine-learning-assisted workflow uses the echo state network (ESN) coupled with an empirical water fractional flow relationship as a proxy to replace time-consuming simulations and improve the computational efficiency of the CLRM. The ESN, under the paradigm of reservoir computing, provides a specific architecture and supervised learning principle for recurrent neural networks (RNNs). ESNs, with randomly generated and invariant input weights and recurrent weights, greatly minimize the computational load and solve potential problems during typical backpropagation through time in traditional RNNs while it still obtains the benefits of RNNs to memorize temporal dependencies. Also, the linear readout layer makes the training much faster using analytical ridge regression. Field-level well control and production-response data are fed into the workflow to obtain a trained ESN and fitted fractional-flow relationship, which will represent/reproduce the dynamics of the reservoir under various well-control scenarios. Further production optimization is directly applied to the matched models to maximize reservoir NPV. The optimized well-control scenario is applied, and further observation is obtained to update the models. History matching and production optimization are performed again in a closed-loop fashion. The previously mentioned advantages make ESN a very powerful tool for CLRM, with both history matching and production optimization quickly accomplished, and make near-real-time CLRM possible. In this paper, two case studies will be presented to prove the effectiveness of the proposed workflow.
