This study investigated upscaling current data caching and prefetching strategies for online databases in Nigeria, with a focus on practical implications. The research design adopted for this study was the descriptive survey. The population comprised of all undergraduate’s library students in public tertiary institutions in Ekiti State. A simple random sampling technique was adopted to select 200 library students from Ekiti State University in the study area. The instrument used for data collection was a structured 4 Likert type questionnaire. The questionnaire was distributed to the respondents to find out the effectiveness of caching and prefetching techniques on online databases. The instrument was both face and content validated by two experts from the department of Library studies in Ekiti State University, Ado-Ekiti State. The reliability of the instrument was ensured using Pearson Product Moment Correlation formula which yielded a coefficient of 0.99. The data collected were analyzed using descriptive statistics such as mean and standard deviation. The result showed that the current caching and prefetching techniques employed in online databases are highly effective; the different access patterns have effect on the effectiveness of caching and prefetching techniques in online databases and there are impacts of cache coherence mechanisms on the efficiency of caching and prefetching techniques in online databases. It was therefore recommended that the inclusion of caching and prefetching in curriculum is important across all educational level in Nigeria, with a clear emphasis on the practical implications. In addition, caching and perfecting have come under fire for focusing mostly on computer science.

Iron (Fe) is one of the many nutrients found in kelakai. Lemon acid treatment (Citrus lemonade) is used in the processing of kelakai tea powder as an effort to increase the nutritional value of the plant. The aim of this research is to determine how temperature and brewing time affect the iron (Fe) content in kelakai leaf tea (Stenochlarna palutris) prepared with lemon acid (Citrus lemonade). This research used a 2 factorial completely randomized design (CRD) and was experimental. There are two factors: the first is the temperature at which the brewing is done (40, 50 and 60 degrees Celsius), and the second is the brewing time (1, 5 and 10 minutes) with three repetitions. Two-Way Analysis of Variance (ANOVA) was used in data analysis, along with an additional 5% Honestly Significant Difference (BNJ) test. These findings show a very significant influence of brewing temperature, brewing time, and the combination of temperature and brewing time. The results of the research show that moderate temperatures produce high iron (Fe) levels, moderate brewing results in high iron (Fe) levels. The brewing temperature treatment T2 (50oC) had the highest amount of calcium at 2.73778 ppm. Iron (Fe) levels are low at temperature T1 (400C) of 1.42000 ppm. The effect of brewing time on high iron (Fe) levels at F2 time (5 minutes) is 2.73778 ppm. The lowest iron (Fe) content was located at the longest brewing time, namely F3 (10 minutes) at 1.12267 ppm. T3F2 (600C, 5 Minutes) with iron (Fe) content of 3,707 ppm. The treatment that produces the lowest iron (Fe) content is T2F3 (500C, 10 minutes) with a value of 0.702 ppm

Hess’ ‘Drainage’ Wells Show Strong Production but Face Cost and Spacing Challenges
Authors: Jacobs Trent 
Published: September 2024

A new kind of horizontal well has emerged from an experiment in North Dakota’s Bakken and Three Forks shales.
It uses an uncemented slotted liner to produce hydrocarbons by intercepting fractures that originate from offset wells.
Hess Corp. revealed the concept over 2 years ago, confirming at an SPE conference that crude was flowing from the pilot well. The New York City-headquartered oil company also announced that additional trials were in progress, though it withheld specific production figures.
The wait for those key details is now over.
At the recent Unconventional Resources Technology Conference (URTeC) in Houston, Hess presented its first technical paper on the augmented drainage development (ADD) pilots which it claims have proven the approach to be, at the very least, a technical success.
In URTeC 4044110, the company’s authors underlined their optimism in noting that ADD wells “could lead to a step change in productivity and recovery in unconventional developments.”
Hess acknowledges that economic and technical hurdles currently stand in the way of that vision.
But the upbeat assessment is backed by impressive production data from its inaugural pilot launched in 2021.
Placed about 240 ft between two actively stimulated Middle Bakken wells, the first drainage well exceeded expectations, averaging nearly 1,700 B/D of crude in the first 8 days of flowback.
Output fell to about 1,500 B/D over the next few days as the nearest actively stimulated well—called a “standard well” by Hess—began its flowback. This was one of several confirmations that the wells were in direct communication.
“A lot of bets were lost on this well—maybe not by me, but by a lot of people,” remarked Craig Cipolla, a principle completions engineering advisor for Hess.
Cipolla presented the company’s findings at the conference this past summer. He said the ADD well also pumped out about as much frac sand as is seen in a typical shale well, which in addition to tracer data, verified that it was well propped.
During the initial production period, the first ADD well achieved about 85% of the output of the offsetting standard wells on the pad. Although this figure eventually dropped to just over 40% over the next 2 years, it was enough for Hess to consider the concept validated.
Based on the results from all three pilots, Hess estimates ADD wells in the Bakken can be expected to achieve 10 to 45% of the output of typical hydraulically fractured horizontal wells.
On the low end, the oil recovered from distant and low-conductivity fractures likely won’t justify drilling even a wellbore as barebones as the ADD concept calls for.
Conversely, if a drainage well produces too much oil it is a sign that well spacing is too tight and that it is overly competing for resources with more-expensive offsets. This is likely the story of why the first ADD well came on so strong.
Fervo Showed Fractured Geothermal Works, Now Must Do It Bigger, Cheaper, and Soon
Authors: Rassenfoss Stephen 
Published: September 2024

Earlier this year, one of the founders of Fervo Energy announced that the geothermal innovator had reached its “Mitchell moment.”
Jack Norbeck, chief technology officer for Fervo, likened a test where it used a pair of fractured wells to create water hot enough to generate electricity to the time when Mitchell Energy adopted slickwater fracturing to economically extract large amounts of gas from the ultratight rock in the Barnett Formation.
“We have derisked all those core challenges, we reached the Mitchell Energy moment for geothermal,” Norbeck said.
By doing all that and supplying 3.5 MW of electricity to the local grid that powers Google facilities, he announced that the firm’s enhanced geothermal system (EGS), had reached the highest level of technical readiness.
Now comes the hard part—proving that technical triumph can be turned into something really big.
The Mitchell moment in 1997 is remembered because it led to a series of innovations that allowed hydraulic fracturing and horizontal drilling to add enough oil and gas production to move global markets.
What has been learned about fracturing in the decades since allowed oil industry veterans at Fervo to effectively use those tools to do what others had failed to accomplish—create high-volume EGS capable of generating power.
One big difference between the moments is that Houston-based Fervo’s next step looks like a leap compared to Mitchell’s.
After Mitchell’s moment, no innovation was required to sell shale gas from the Barnett or find the oilfield services needed to develop and produce it. Plus, it could learn from the many other companies working in tight rock plays.
Its moment was the culmination of years of innovations by oil and service companies who continued finding ways to build on that advance. The endless arguments over who can claim credit for the innovations behind the Mitchell moment are evidence of the size of that support network.
Today, Fervo’s efforts are also supported by the oil industry’s service sector and supply chain.
Oil company Devon Energy, drilling contractor Helmerich & Payne, and pressure-pumping specialist Liberty Energy are among its early backers. And Fervo is benefiting from the government-funded research and site-evaluation work at the Utah Frontier Observatory for Research in Geothermal Energy (FORGE) site, which is the key site for geothermal testing funded by the US Department of Energy (DOE).
But unlike Mitchell, the path to commercial success will require Fervo and others to show they can create large operations to convert the heat they harvest into a cost-competitive commodity in a fast-changing, highly competitive industry.
Sage Geosystems recently was added to the short list of geothermal startups with big projects, signing a deal with Meta to build a 150-MW plant somewhere east of the Rockies. Also high on the list is Eavor whose first commercial project will use its closed-loop heating technology for home heating and electric generation in Germany.
Technology Focus: Reservoir Surveillance (September 2024)
Authors: Khan Muhammad Navaid 
Published: September 2024

In today’s oil and gas operations, surveillance technologies have undergone a revolution, reshaping how facilities, wells, and reservoirs are monitored. These advancements not only have increased the scale at which these technologies are deployed but also have led to an unprecedented influx of data. The sheer volume of data, however, poses a significant challenge to traditional analytical methods, overwhelming their capacity to derive actionable insights effectively.
To address this challenge, the industry is rapidly advancing toward automated solutions powered by artificial-intelligence (AI) -driven analytics. These systems automate data ingestion and use machine-learning algorithms to sift through massive data sets, identifying anomalies and prioritizing actionable insights. By automating routine surveillance tasks, engineers can focus on critical actions that deliver substantial operational benefits.
For example, in paper IPTC 23912, operators successfully optimized production operations by harnessing real-time field data through smart systems, effectively managing operations with complex near-critical fluids. Similarly, in paper SPE 218470, researchers proposed a novel workflow integrating virtual flowmetering and permanent downhole gauge data for pattern recognition to enhance real-time monitoring and decision-making in petroleum and geothermal industries.
Nevertheless, ensuring effective surveillance of operational assets requires a strategic approach. A valuable tool in crafting such strategies is the value of information (VOI) assessment. This method systematically evaluates how acquiring specific information can influence decision-making and operational outcomes. For instance, paper SPE 215318 highlights a field operator’s systematic approach to VOI assessment, aiming to optimize daily operations and guide future development activities.
In essence, while surveillance technologies have inundated operators with unprecedented data flows, advancements in automation and AI-driven analytics offer the promise of unlocking this data’s true potential. By embracing these technologies, the oil and gas industry can navigate the complexities of the modern energy landscape with greater agility, precision, and cost-effectiveness.

Reliability analysis of 50000 kN hydraulic support test bench under shrinkage test conditions
Authors: Jiang Biao , Han Liguo , Zhao Lijuan , Pang Qingqing , Gao Qizhang , Du Na 
Published: September 2024

The large mining-height hydraulic support test-bed serves as a crucial tool for heavy hydraulic support factory inspections and type testing. With the successful development of the ZY29000/45/100D hydraulic support, the need for a large high-mining hydraulic support test-bed has become evident. This paper combines the theory of rigid-flexible coupling in virtual prototypes and ADAMS multi-body dynamic simulation technology to analyze the strength of the 50,000 kN hydraulic support test-bed. ANSYS classic modules were employed to address the flexibility of key components within the test-bed. The fatigue life of the test-bed was analyzed using NSOFT software, the von Mises yield criterion, and the Goodman modified curve. The S-N curve of material parameters for the test-bed components was used to conduct a shrinkage test. The results indicate that the lowest position is the most vulnerable during the shrinkage test. Among the key components, the stress on the pin bearing is 356.6 MPa, which is 167.9 %, 123.3 %, and 41.6 % higher than that of the pillar, movable beam, and base, respectively. The fatigue life of the base under low, medium, and high shrinkage conditions is1.1×107, 4.0×108, and 1.7×108, with damage values of 8.8×10-8, 2.5×10-9, and 5.7×10-9, respectively. The base’s life under low shrinkage conditions is the shortest, followed by that under high shrinkage conditions. These research findings provide technical guidance and an optimization foundation for the successful development of a 50000 kN hydraulic support test-bed. They also offer a new method and approach for analyzing and predicting the fatigue life of key components in large-scale industrial and mining equipment operating under complex conditions, with promising practical applications.

Published: September 2024

Abstract

Background
There is a shortage of competent health professionals in managing malnutrition. Online education may be a practical and flexible approach to address this gap.

Objective
This study aimed to identify essential competencies and assess the effectiveness of an online course on pediatric malnutrition in improving the knowledge of pediatricians and health professionals.

Methods
A focus group (n=5) and Delphi technique (n=21 health professionals) were used to identify 68 essential competencies. An online course consisting of 4 educational modules in Microsoft PowerPoint (Microsoft Corp) slide form with visual aids (photos and videos) was designed and published on the Syrian Virtual University platform website using an asynchronous e-learning system. The course covered definition, classification, epidemiology, anthropometrics, treatment, and consequences. Participants (n=10) completed a pretest of 40 multiple-choice questions, accessed the course, completed a posttest after a specified period, and filled out a questionnaire to measure their attitude and assess their satisfaction.

Results
A total of 68 essential competencies were identified, categorized into 3 domains: knowledge (24 competencies), skills (29 competencies), and attitudes (15 competencies). These competencies were further classified based on their focus area: etiology (10 competencies), assessment and diagnosis (21 competencies), and management (37 competencies). Further, 10 volunteers, consisting of 5 pediatricians and 5 health professionals, participated in this study over a 2-week period. A statistically significant increase in knowledge was observed among participants following completion of the online course (pretest mean 24.2, SD 6.1, and posttest mean 35.2, SD 3.3; P<.001). Pediatricians demonstrated higher pre- and posttest scores compared to other health care professionals (all P values were <.05). Prior malnutrition training within the past year positively impacted pretest scores (P=.03). Participants highly rated the course (mean satisfaction score >3.0 on a 5-point Likert scale), with 60% (6/10) favoring a blended learning approach.

Conclusions
In total, 68 essential competencies are required for pediatricians to manage children who are malnourished. The online course effectively improved knowledge acquisition among health care professionals, with high participant satisfaction and approval of the e-learning environment.
