This study explores the influence of mindfulness and self-efficacy on the emotional regulation of high school students. Emotion regulation is the ability of individuals to manage and control their emotions effectively, which is very important in students' psychological development. Along with the increasing academic and social demands among high school students, mindfulness and self-efficacy are essential to help better regulate emotions. This study uses a quantitative survey method. The research population was 139 high school students, with a sample of 104 students using the Proportionate Stratified Random Sampling technique. Data were collected through questionnaires tested for validity and reliability and then analyzed using multiple regression techniques to test the influence of mindfulness and self-efficacy on emotional regulation. The study showed that mindfulness and self-efficacy positively and significantly affected students' emotional regulation. Mindfulness, which includes full attention to the physical body, feelings, and mind, has been proven to help students be more aware of their emotions and manage them more effectively. Self-efficacy, as an individual's belief in their ability to overcome challenges, is significant in helping students cope with difficult emotional situations.

Where is the Anchor? Explaining the Endurance of the American-Turkish Partnership, 1927-2024
Authors: Erpul Onur , Kirişci Kemal
Published: January 2025

Once considered a model partnership, the American-Turkish relationship now
elicits ambivalence among scholars and policymakers, calling into question the
fundamental interests and assumptions that once undergirded the relationship.
Critics attribute the negative trends in the relationship to geostrategic and
value-based incompatibilities, but relatively few have examined both factors
longitudinally across the entire relationship. This paper does not aim to
provide a grand theory of American-Turkish relations. Instead, its goal is to
develop a framework illustrating the vital role that strategic, ideational, and
domestic political factors have played in shaping macro-level outcomes in the
partnership’s cohesion at various junctures. Overall, our paper identifies the
positive role of foreign policy bureaucratic elites on both sides acting as an
“invisible hand” providing an anchor for the relationship even in the absence of
other commonalities. Yet, we also observe the weakening of this hand in recent
times as both countries become domestically transformed.

En un entorno empresarial altamente competente, las competencias digitales emergen como un componente crucial para el avance de la productividad laboral en las estructuras empresariales. En este estudio se propuso como objetivo determinar la relación entre las competencias digitales y la productividad laboral del área comercial en una entidad financiera de Lima-Perú, 2023. Con la finalidad de realizar un análisis más detallado, se desglosaron la variable competencias digitales en tres dimensiones: la comunicación, seguridad y resolución de problemas, asimismo la variable de productividad laboral se fraccionó en otras tres dimensiones: la eficiencia, efectividad y adaptabilidad. La investigación se realizó con un enfoque cuantitativo, con un alcance correlacional y se empleó un diseño no experimental transeccional; los colaboradores fueron 58 asesores del área comercial de una entidad financiera en cuestión a quienes se les administró un cuestionario tipo Likert conformado por 24 ítems para recopilar datos. Los resultados revelaron que las competencias digitales se relacionan significativamente en la productividad laboral, con un coeficiente de Spearman de 0.533. De esta manera, se identificó una relación directa de dicha variable en la resolución de problemas con coeficientes de Spearman de 0.650. Sin embargo, existe una brecha en la capacidad de los asesores entre la comunicación y la seguridad respectivamente (coeficiente de Spearman de 0.341 y 0.364) lo que evidencia la necesidad de perfeccionar los métodos de adquisición de habilidades. Se destaca especialmente el papel esencial de las competencias digitales en el ámbito privado, ofreciendo valiosas perspectivas para orientar futuras políticas y prácticas.

Published: January 2025

Gas reservoirs in deep formations, with low pressure and low permeability, present a significant production challenge due to the low conductivity of the rock. The hydraulic fracturing technique has been used historically to increase the flow area available to produce hydrocarbons in this type of reservoir.

Particularly, the case of Piedemonte area in the Llanos basin in Colombia, presents additional challenges for stimulation due to the high capillary pressure required by the water-based fluids to be able to move through the small pore throats, causing restriction for their injection and difficulty to flowback to surface. This causes retention of the liquid phase in the rock matrix and trapping mechanisms that prevent obtaining the full benefit of the stimulation technique.

To address this problem, fracturing fluids assisted/energized with CO2 are usually used, whose benefits are focused on: 1) reducing the volume of water injected and mitigating blockage; 2) mitigate the reservoir filling effect associated with fracturing diagnostic tests; 3) reduce the burst pressure due to the cracking by low temperatures; 4) improve the geometry of the fracture due to the greater efficiency of the CO2 fluid carrying and placing the proppant; 5) capture of CO2 from the refining processes and its integration back into the reservoir to increase stimulation efficiency.

This article presents a compilation of the stages performed for the job, from its planning and design, through the assurance of the stimulation fluids with specialized laboratory tests and finally, its execution and results.

Research was made on similar cases around the world, taking the best practices and recommendations for the work. Next, multiple tests were executed in the laboratory such as rheology with the base fluid seeking to reduce the concentration of the polymer and ensuring its performance under the reservoir conditions. Moreover, a low risk of asphaltene precipitation was identified in the hydrocarbon/ CO2 interaction and displacement tests in a representative core achieving 100% regained permeability.

Finally, in March 2024, the first CO2 -assisted fracturing pilot was executed in Floreña field. The well is currently in the cleaning process and is pending production evaluation. The work not only describes the best practices used, but also aims to establish improvement criteria for future jobs.
Predicting Stage Isolation in the Vaca Muerta Formation Using Surface Pressure Diagnostics
Authors: Verrastro F. , Bonapace J. C. , Rodriguez M. B. , Goñi L.
Published: January 2025

This work presents a workflow applied to 27 wells of the Fortin de Piedra Field in Vaca Muerta that can determine the likelihood of isolation problems during fracture stimulation by analyzing pump-down data and comparing fracturing pressures within the same well, providing a practical method to evaluate zonal isolation without specialized downhole instrumentation.

The approach involves a simple workflow that has been applied to analyze 796 plug-and-perf jobs and 11 plugs from different vendors. It starts by categorizing the pressure morphology of pump down diagnostics (water hammer, isolation confirmation, breakdown pressure) to accurately predict if a given job is likely to exhibit lower-than-expected treating pressures and thus, isolation issues. These were tailored with different options based on the available time to have no impact on the efficiency of the operations. Complementary diagnostics such as step-down rate tests and pre/post frac water hammer analysis was also conducted to corroborate the findings.

By applying this consistent workflow, the authors were able to determine with 81% accuracy whether a given job was likely to exhibit isolation issues. This assessment was made solely based on diagnostic data collected during pump-down operations, without the need for specialized downhole monitoring equipment. A simple calculation for the limited entry designs employed suggests that the most likely source of the difference between expected and real treating pressure during the job must be an increased flow area inside the casing, indicating potential plug failure.

With this method, the authors were able to get an early warning when the proportion of stages with isolation problems became higher than usual. Surface tests carried out on those plugs confirmed these findings. Additionally, parent wells showed higher intensity Fracture Driven Interactions from stages where isolation issues were identified.

This paper presents a cost-effective workflow to evaluate zonal isolation in unconventional wells without the need for advanced downhole diagnostics. By applying this workflow, operators can better select and identify the most suitable plug for their operations, improving effectiveness of fracture stimulation treatments.
Monitoring the Effectiveness of a Bullhead Refrac Using Temporarily Deployed Fiber Optic Cable
Authors: Traweek R. , Rice J. , Gattis T. , Chamberlain C. , Del Zoppo M. , Van Buskirk P. , Dutta P.
Published: January 2025

Bullhead refracturing (refrac) treatments in horizontal wells with multiple entry points historically have been particularly challenging to characterize and interpret during the secondary stimulation. Lateral coverage and success are typically measured after the completion of the refrac. This has limited our industry’s ability to connect surface delivery techniques with subsurface responses on a per well basis. This paper presents a unique low-cost approach to monitoring bullhead refracs using a temporarily deployed fiber optic cable focused on real-time data gathering and immediate feedback.

The well development project presented an opportunity to deploy a temporary (single use disposable) fiber optic cable into a newly drilled, uncompleted child well. Disposable fiber optic cable was deployed successfully to the toe of the new drill, which paralleled a series of parent wells of which two were candidates for refracs (Figure 1). Data gathered in the monitoring program included Distributed Acoustic Sensing (DAS) and Distributed Strain Sensing (DSS). The primary focus of the project was to deploy fiber successfully into the child well and monitor the effectiveness of the refrac treatment of each subsequent parent well as it progressed.

Once in place, DSS data was streamed live allowing for a continuous visual of strain across the full lateral section and spanning the full treatment time period of each well. This allowed for identification of lateral coverage during the pressure sink mitigation (PSM) and bullhead refrac treatment, as well as duration of hydraulic connection to the formation at each point along the lateral. The data gathered and simultaneously displayed, provided instant feedback as to surface execution decisions and subsurface impacts. This approach allowed the key personnel to optimize the completion by identifying the time period of maximum effectiveness to end the treatment at that point, resulting in a savings of material and pump time. Additionally observed fracture-driven interactions from parent well refracs to the child well allowed for further child well treatment analysis once the child well’s primary completion was executed. Within acreage containing simultaneous refrac and new drill programs, this approach can be used to maximize the efficiency of both programs by characterizing the treatment of both depleted and non-depleted reservoir.

Multi-stage stimulation has become a cornerstone of unconventional reservoir development. Enabling enhanced hydrocarbon recovery through precise zonal stimulation and achieving 100% isolation between stages is critical to ensure the success of these operations. Effective isolation prevents cross-flow, ensures even distribution of fracturing fluids, and enhances the effectiveness of proppant placement within targeted zones This results in maximum reservoir contact, minimizes fluid loss, and reduces the risk of premature screen-outs or pressure interference between stages. Furthermore, robust isolation improves well productivity, optimizes resource utilization, and reduces operational costs. The use of frac plugs plays a pivotal role in achieving reliable isolation under varying downhole conditions. This paper will describe the significance of 100% isolation in enhancing stimulation efficiency and discusses challenges associated with achieving it. By highlighting the operational and economic benefits of complete isolation, this study emphasizes isolation as a fundamental requirement for successful multi-stage stimulation in modern oil and gas practices.
Slicing the Onion of Multi-Variate Unconventional Stimulation Optimization

The optimization of unconventional oil and gas assets requires simultaneous consideration of fracturing and porous media flow phenomena. Many recent works have demonstrated that a fully coupled fracturing and flow modeling workflow can be used for a variety of applications (McClure et al., 2023; Fowler et al., 2023, Pearson et al., 2022). By coupling fracturing and production physics, solutions implicitly reconcile the impact of fracturing designs on well productivity and resource recovery.

In order to optimize fracturing design for a pad of upcoming wells in their Bakken development, Liberty Resources constructed a coupled model which was calibrated and used in an optimization workflow and documented in URTeC paper 4043244 (Pearson et al, 2024). The presented dataset was calibrated against a five well development program in a 2x1 mile spacing unit – one parent well followed by 4 infill wells drilled after 3-/1/2 years of production.

Single-variate analysis of a non-optimized dataset was shown to be significantly inferior to a multi-variate optimization process to develop a "cloud" or "onion" of datapoints allowing the operator to select an economic optimum that either focused on Discounted Profitability Index (return of capital) or Present Value created.

The scope of this paper is to take the multivariate datasets presented in URTeC 4043244 and to dissect them for the individual single variate components. A genetic-algorithm multi-variate optimization procedure was used on the history matched dataset. The first generation used a space-filling design, sampling all regions of the design parameter space (where each completion/stimulation design variable is a parameter). Subsequent generations goal-seek the optimal objective value based on the results of the prior generation. The overall result of the process is a cloud or "onion" of optimization points as a function of the economic parameter being considered. This paper presents the optimized results as sliced datasets which immediately allows the completions engineer to visualize the dependence of the multivariate optimization on the individual components in the completion design.

Limited entry design has been utilized to enhance distribution of fracture fluid and proppant across clusters in multi-stage fracture stimulation for horizontal wells. The concept uses limited perforation diameter/number to generate perforation frictional pressure drop to control fluid distribution through perforations, and the goal is to evenly distribute fracture fluid over all clusters. However, in today's field practice, high injection rate and large volume of proppant injection often lead to severe erosion of the perforations, resulting in reduced perforation friction and lower fracturing efficiency. Distributed Acoustic Sensing (DAS) positioned behind the injection wellbore monitors acoustic vibrations generated by slurry injection at the clusters in real time. This enables monitoring and evaluating of the dynamic changes in perforation size and slurry distribution, as indicated by the decay of the DAS signal.

This paper presents a methodology that qualitatively determines the fluid distribution and perforation size for individual clusters using field DAS data. A correlation between the perforation diameter, flow rate and the induced sound pressure intensity are developed based on Computational Fluid Dynamics (CFD) acoustic simulation results. By integrating the acoustic correlation and the wellbore energy balance equation, slurry distribution and perforation size at clusters are simultaneously calculated at every time step in a multi-cluster stage. This calculation is repeated until the end of the treatment, and the cumulative fluid allocation and the post-fracture perforation size are estimated.

The correlation is applied to a field DAS data set. The estimated eroded diameters are compared with post-fracture perforation images taken by a downhole video camera. The estimated cumulative fluid volumes are compared with the interpretation of Distributed Temperature Sensing (DTS). In both datasets, the overall trends are consistent. Two clusters where the perforations were heavily eroded are identified by the DAS interpretation.

These comparisons and the agreements of the results support the validation of the new acoustic correlation and the new DAS interpretation methodology. The DAS interpretation methodology helps observe the process of perforation erosion and understand its mechanism, leading to an improvement of perforation design.

In this study, we construct and calibrate simulation models of four field-scale datasets: two from the Bakken, one from the Delaware Basin, and one from the Midland Basin. The datasets include diagnostics such as: offset pressure observation wells, cross-well and injection-well fiber, interference tests, post-frac perforation imaging, and production data. For each dataset, we build a list of ‘key observations’ and then vary model parameters to match each observation. The pressure observation wells and the interference tests provide strong constraint on far-field pressure depletion. The calibrated models provide more confidence in the spatial and temporal evolution of fracture conductivity over time. Key conclusions are: (a) fractures are finite conductivity, exhibiting large and persistent pressure gradient during long-term production, (b) fracture conductivity diminishes with distance from the well, (c) fracture conductivity decreases with pressure drawdown, and also, fracture conductivity decreases as a direct function of time, (d) proppant ‘immobilization’ (or, ‘trapping’) caused by fracture roughness is a key determinant of the propped length, (e) the magnitude of proppant trapping appears to a function of both formation properties and mesh size, (f) more speculatively, the magnitude of proppant trapping may also be related to fluid velocity/rate per cluster, and (g) it is advantageous to perform fracture injection testing to measure the pressure and stress profile above the pay zone, especially in formations where significant pore pressure variability is suspected above the target zone.

This paper demonstrates how the integration of multi-physics downhole imaging with machine learning techniques provides a step-change in perforation erosion analysis. We present a novel approach that improves measurement accuracy, consistency, and turnaround time. We reveal how this benefits the fields of completion design and optimisation of hydraulic fracturing, and how this enables gains in productivity and reduction in cost in the development of unconventional wells.

Downhole data is acquired from an integrated array video and phased array ultrasound sensor system. The video is analysed by a two-stage artificial intelligence process to identify perforations within the well and measure their geometries. High quality optical image results are used to train a third artificial intelligence algorithm that identifies and analyses the same perforation geometries from the corresponding ultrasound dataset.

This approach reveals trends in erosional metal loss induced by proppant flow through perforations. This quantitative evaluation of proppant placement and analysis of its uniformity enables engineers to compare the effectiveness of completion designs and the frac operations.

Through experimental data, real-world case studies, and comparisons with conventional workflows, we demonstrate:

Acceleration of the analysis process through automation Improved data quality and consistency by minimizing human error and subjectivity How the use of the video data, with a resolution ten times greater than the ultrasound sensor, as a ground truth and training parameter has been used to dramatically improve the correlation of the two datasets, creating a highly reliable determination of perforation geometries in the widest possible range of well conditions.

Specific case studies included within the paper are as follows:

The application of downhole video measurements, and the evolution of machine learning-enhanced processing. We chart the speed, accuracy and consistency of results from conventional and machine learning-enhanced processes. The integration of video and ultrasound measurements, the correlation between datasets, and the improvements in data integrity resulting from a multi-physics approach. The application of artificial intelligence to optimise measurements from the ultrasound sensor trained using video measurements, and the improvements in the accuracy and reliability of the resulting dataset.

Analysis techniques have been refined and training algorithms developed using both controlled surface tests and a database of over 100,000 perforation images obtained from hydraulically fractured wells. This paper presents the first publication of this unique three-tier artificial intelligence approach, and the results obtained from its application in the field.
