Authors: Sánchez-Yarmas Elsa M.
Published: October 2021

La presente investigación tuvo como propósito analizar la relación entre la adicción a internet, la resiliencia y el rendimiento escolar en adolescentes de los distritos de Yarinacocha y Callería, ciudad de Pucallpa, en la región Ucayali (Perú). Esta región se caracteriza por concentrar la población de adolescentes con los niveles más bajos en rendimiento académico y que no estudian ni trabajan. El estudio es descriptivo, correlacional y comparativo. La muestra de estudio fue de 519 estudiantes de tercero, cuarto y quinto de secundaria, en edades de 14 a 18 años. Los instrumentos fueron la Escala de Resiliencia de Wagnild y Young, adaptada por Novella (2002), el Test de Adicción a Internet de Young, adaptado por Matalinares et al. (2012) y las calificaciones, brindadas por las instituciones educativas. Se hallaron correlaciones positivas pero bajas entre adicción a internet y resiliencia, y correlaciones negativas bajas entre adicción a internet y rendimiento, con tamaños de efecto pequeños o insignificantes. Se concluye que la resiliencia no parece ser un factor importante en el desempeño académico en este grupo y que es necesario desarrollar estudios posteriores en adolescentes que están fuera del sistema educativo a fin de contrastar con los presentes hallazgos.

Abstract

The existence of public open space on the banks of the Musi river, Palembang has not been used optimally, such as the 7 Ulu courtyard area in the Kapitan Village area which is empty of visitors. Utilization of the function of river banks into public open spaces is not accompanied by the development of adequate infrastructure facilities. Through this research, it will be studied about the need for facilities, service levels and the economic value of developing facilities in the courtyard area of ​​7 Ulu. To be able to find out what needs to be improved, it is necessary to observe the physical setting and activities, the weighting of the existing facilities based on the waterfront design character criteria using the Likert scale method, analysis of the level of service in the yard and the need for facilities using the level of service method. The investment value of the added facilities was analyzed using net present value, payback periods, internal rate of return and depreciation. From the analysis of the investment value, it is known that the planning of tourist pier facilities, culinary, and billboards makes the planning of the 7 Ulu facility worthy of investment. Improvement of public service standards such as reaching the courtyard, supporting facilities and security must be contextual with the character of the area so that the arrangement of the courtyard can support the 7 Ulu conservation area

Installation resilience in cold regions using energy storage systems
Authors: Callaghan Caitlin , Peterson Danielle , Cooke Timothy , Booker Brandon , Trubac Kathryn
Published: October 2021

Electrical energy storage (EES) has emerged as a key enabler for access to electricity in remote environments and in those environments where other external factors challenge access to reliable electricity. In cold climates, energy storage technologies face challenging conditions that can inhibit their performance and utility to provide electricity. Use of available energy storage technologies has the potential to improve Army installation resilience by providing more consistent and reliable power to critical infrastructure and, potentially, to broader infrastructure and operations. Sustainable power, whether for long durations under normal operating conditions or for enhancing operational resilience, improves an installation’s ability to maintain continuity of operations for both on- and off-installation missions. Therefore, this work assesses the maturity of energy storage technologies to provide energy stability for Army installations in cold regions, especially to meet critical power demands. The information summarized in this technical report provides a reference for considering various energy storage technologies to support specific applications at Army installations, especially those installations in cold regions.

Published: October 2021

Pepper yellow leaf curl virus (PepYLCV) infection transmitted by silverleaf whitefly (Bemisia tabaci [Gennadius]) can decrease chili pepper yield up to 100%. At this moment, there is no chili pepper variety resistant to PepYLCV available. Genome editing approach through CRISPR/Cas9 is an effort to develop variety resistance to the viral infection. The purpose of this study was to obtain M2 lines developed by CRISPR/Cas9 system on proliferating cell nuclear antigen (PCNA) gene for resistance to PepYLCV. A total of four M2 lines (C47-7, L84-2, L84-23, and L120-19) consisting of 60 chili plants were tested for their resistance to PepYLCV. PCR analysis was performed to detect the presence (infection) of the virus. The results showed that a total of 35 plants derived from the four lines were resistant to PepYLCV. They consisted of 7 plants from C47-7 line, 11 plants from L84-2 line, 9 plants from L84-23 line, and 8 plants from L120-19 line. PCR analysis confirmed that the resistant plants obtained from this study were negatively infected by the virus. Since not all tested plants were resistant to virus infection, the PCNA gene allele in these resistant lines were most likely heterozigotes. Sequencing of PCNA gene of the resistant lines is needed to confirm that the resistance phenotypes obtained was due to mutation of the gene. Therefore, further selection needs to be performed to obtain stable and PepYLCV-resistant lines.
Heavy Weight Cement System for Corrosive Environment: Preventing Strength Retrogression and H2S Corrosion

Well cementing in high temperature and hydrogen sulfide (H2S) corrosive environment presents challenges in preventing cement compressive strength retrogression and selecting weighting agents inert to H2S.

This paper presents the development of a cementing system for high pressure high temperature (HPHT) well with bottom hole static temperature in excess of 165°C, a drilling fluid density of 2.19 SG and a high concentration of H2S. A major operator in the Caspian Sea region accepted the cement design and successfully used it on the production liner section of the HPHT well.

Cementing of the production liner was complex due to the requirement for a high-density cement system, narrow margin between the pore pressure and frac gradient, HPHT conditions and 18% H2S concentration in the formation fluid. Comprehensive laboratory testing was performed to evaluate the properties of the cement system including measurements of thickening time and compressive strength evaluation using a UCA and destructive method using ultra-HPHT curing chamber for cube sample curing.

The presence of H2S limited the use of conventional weighting agents such as hematite and hausmannite, and the high temperature environment dictated the need for quartz silica. These factors required a nonstandard approach to cement blend formulation and flowability assessment.

During cement system optimization, the target slurry density was achieved using barite which has a lower density compared to other common weighting agents and significantly reduces cement content in the blend but also is inert to H2S corrosion.

A further challenge encountered during cement system optimization was strength retrogression that could not be prevented by the conventional approach of adding 30-40% quartz silica by weight of cement into the system. To overcome strength retrogression, much higher concentrations of silica were required. As a result, the low cement content led to insufficient compressive strength development at liner hanger depth. A solution was found by adding a Vinylamide/Vinylsulfonated polymer (VA/VS) polymer in a certain proportion to the slurry design. Thus, at elevated temperatures, it was observed that the VA/VS polymer tended not to delay compressive strength development while still extending the slurry thickening time.

The developed heavy weight cement system was successfully implemented to isolate the 7-in liner on HPHT well. All the stages of job planning, design and execution, along with the slurry optimization process are presented.
Optimized Coiled Tubing Approach in Offshore Multi-Stage Hydraulic Fracturing Project
Authors: Rahimov K. , Correa P. , Sharipov R.
Published: October 2021

Operator at the Russian segment of the Caspian sea offshore, engineered a project to drill and complete four experimental horizontal extended reach wells with very aggressive trajectories, into tight Oil & Gas bearing formations with further mission to complete them with multiple hydraulic fracturing. This resulted in a selection of complex completion design with multiple shifting sleeves to allow efficient multistage frac treatment and subsequent production of each zone.

Technical challenge of the project was to deliver enough force into shifting sleeves to manipulate them with close-open-close cycle, in a horizontal extended reach wellbore with average 2800mMD (1900mTVD) with anticipated excessive proppant accumulation after each treatment, and it was expected to further restrict the required force delivery in extended reach wellbore.

Challenges were addressed during well design stage, by using a proprietary engineering simulation software to analyze the large spectrum of the Coiled tubing string with different mechanical properties. Additionally, feasibility study, considered the application of downhole aids to overcome wellbore cleanout issues, helical buckling and friction lock-up, to deliver required force to the shifting devices.

A critical part for the effective delivery of the operations was the time spent designing each intervention individually. Having the expertise to perform proper project management, provided the opportunity to identify several potential challenges that could appear during the campaign. Numerous simulations of tubing force analysis were performed, considering different string configurations, in the intent of overcoming the difficulties resulting from the unconventional trajectories of the wells. One important selection made, was the extended reach auxiliary options, which could aid in reaching the target depths with enough WoB to shift the sleeves. The feasibility study also included extensive simulations on options to remove solids from the wellbore on an efficient manner

This paper details out the design specification of the Coiled Tubing technologies selected for the projects as well as address the engineering and operational challenges and solutions proposed to deliver the successful offshore campaign. First time use of the large 2 5/8" OD coiled Tubing string in Offshore Caspian sea and related operational and logistical challenges are the novelties discussed in this paper. Paper also highlights the operation sequence and success of the selected pipe design and downhole approach.
Combined Application of Deep Boundary Detection Tool, Multilayer Data Inversion and 3D Visualization of Seismic Data in Real Time for Geosteering on the Oilfield in the Russian Federation

Published: October 2021

Currently drilling of horizontal wells is a common enhanced oil recovery method. Geosteering services are often used for accurate well placement, which makes it possible to achieve a significant increase in production at relatively low cost.

This paper describes the result of using seismic data in three-dimensional visualization for high-quality geosteering using a deep boundary detection tool and multilayer inversion in real time.

Crossing the top of the reservoir while drilling horizontal sections at the current oilfield is unacceptable, due to the presence of reactive mudstones. In case of crossing the top of reservoir, further work on running and installing the liner becomes impossible due to instability and may lead to well collapse.

Based on prewell analysis of the structural data, the well was not supposed to approach the top of the target formation along the planned profile. However, while preparing geosteering model and analyzing seismic data it became possible to reveal that risk, elaborate its mitigation and eventually increase the length of the horizontal section.

Such integrated analysis made it possible to maintain the wellbore within the target reservoirs, as well as to update the structural bedding of the top based on the multilayer inversion results.
Petroleum Systems Modeling and Hydrocarbon Migration and Oil Potential Assessment of the Southern Side of Pre-Caspian Basin, Kazakhstan
Authors: Urmanova Dilyara
Published: October 2021

An active oil system is recognized from the data in the Tengiz-Primorsky uplift zone of the southern edge of the Pre-Caspian Basin in stratigraphic ascending and structural traps of the Famennian carbonate reservoir. This area is considered one of the most high-yeilding gas provinces in Kazakhstan. However, the timing of the displacement and migration of hydrocarbons depending on the formation of traps remains unclear. To reduce this uncertainty, an attempt was made to analyze a cross-sectional model that takes into account seismic structural interpretation and data from the Ansagan 1 well to simulate history, temperature, sourcerock maturity and pressure regimes over geological time. The displacement of hydrocarbons from the original rocks and further HC migration were modeled using 2D reservoir fluid flow modeling based on the Darcy flow equation. The main blocks of the source rocks correspond to the Devonian complex with the influence of algal lipids or organic matter enriched in lipids (type I kerogen). The maturity trend increases from east to west due to higher burial.

The general objectives of this article were to set goals and determine the level of detalization of the research; selection and preparation of input data, filling the model with information, restoring the basin immersion history, calculating the thermal model, and determining the maturity of source deposits, calibrating the thermal model, calculating HC emigration; assessment of migration routes.

Published: October 2021

This article presents the results of fingerprinting and biomarker analysis of 254 oil samples derived from 11 different fields and structures in Aryskum downfold of the South-Torgay depression for genetic classification of oils and prediction of petroleum migration pathways. According to the oil fingerprinting results based on patented Shell technology, 12 groups of oils were found: oils in reservoirs of central part of Nuraly field form the first group, while oils in the producing horizons of Western Nuraly, Southern Khayrgeldy, Akshabulak East and fluvial beds of Central Akshabulak fields form the second group. The oils related to the third group were found in the wells exploiting producing horizon I in the north dome of Central Akshabulak, while the oils from wells penetrating lower producing horizons(III-IV-V) of Central Akshabulak, upper producing horizons in South dome of Central Akshabulak and of all producing horizons of the north dome of Akshabulak South constitute the fourth group.

The fifth group includes only one oil sample of different genesis from well № 37, which penetrates the paleo-channel №13 at South Akshabulak. The genetic difference of this oil from other oils was also confirmed by its biomarker composition. Most of oil fingerprinting star plots in Aksay field are identical and form the sixth group, although the seventh group comprises only one oil № 47 in Aksay. Sample set with №8 was discovered in the pay zones of Taur field and well № 75, exploiting the same horizon in the northern part of Aksay. The ninth oil group was identified in cretaceous producing layers of the Khairgeldy South-West field and Jurassic beds of the Khargeldy North field, while the identical composition of the cretaceous oil from the Khairgeldy North and Khairgeldy fields forms the tenth group. The last eleventh group includes oil from well №. 12 on South-west Khairgeldy, although it has some similarities with Taur oils.

For 20 oil samples was carried out biomarker analysis, according to the results of which all studied oils were formed in terrigenous (shaly) OM, deposited in lacustrine environment. Oils from central Nuraly are more thermally mature and lighter in density than those from western Nuraly. Oils of Akshabulak East are thermally less mature than oils of Central Akshabulak and Akshabulak South despite its deeper deposition.

Based on the performed analysis, in the conclusion were presented 5 prospective hydrocarbon accumulation zones for increasing hydrocarbon reserves in the future. But the results of the performed studies provide valuable information only when integrated with confirmed geological and seismic data.

The 74th step of "100 Concrete Step of Nation Plan" initiated by the first president of the Republic of Kazakhstan (RoK) Nursultan Nazarbayev states that Kazakhstani reserves reporting system must be changed to the international standards. One of them actively proposed is the SPE-PRMS. Therefore, the main goal of the paper is to show challenges of the transition, discuss possible problems, their solution and, eventually, advantages for the companies.

In the paper the main aspects of the current State Committee of Reserves (SCR) system or well-known as GKZ system inherited from the Soviet system and used in Kazakhstan are reported. Especially, we try to highlight the reserves categories of A, B, C1 and C2 and their impact on further field development in details. Also SPE-PRMS and SEC rules are shown in terms of differences and similarities with the current system. Importantly, authors demonstrate how the SPE-PRMS standards are wide-spread around the globe. Finally, details of planned shift, some recommendations and simplification of reporting process are exhibited.

As the result of the study the following points are investigated. Firstly, what will be with reports just recently approved by the SCR. Especially, for the big fields whose preparation takes up to several years. Secondly, what the frequency is for the reporting. Thirdly, whether the reports will be handled through several approval stages or just submitted. Moreover, how close to SPE-PRMS the new system should be adopted taking into account Kazahstani realities and if the reports should be composed in English along with Russian, since the main purpose of the transition is to be clear and transparent for the foreign investors. Otherwise, unfamiliar language and big deviation from the well-known standards may ruin the efforts. Despite the complexity of these issues the benefits of the new system are obvious and there are several reasons. The main advantage is that the SPE-PRMS is all about economically recoverable reserves without any ties with fixed recovery factor. In addition, report is done in short time and less volume. Finally, if the norm of the report's submission without going to tedious approval process is accepted, that will ease work of the subsoil users’ because it accelerates further preparation of field development project.

The study is done due to recent changes of the RoK subsoil usage regulations, where the requirement for reserves reporting system's transition to the new international standards is mentioned. However, the issue is not much highlighted in technical publications from the operating companies’ point of view. Thus, having experience with GKZ, SPE-PRMS and SEC systems the authors take this opportunity to show challenges and benefits of the decision.

Proactive well diagnostic surveillance helps with safe delivery of production by effective well management and risk mitigation. The objective of the paper is to demonstrate the data analytics approach utilizing passive acoustic technology in combination with conventional methods of detecting low magnitude dynamic events behind single or multiple casing strings. The results of integrated interpretation of passive acoustic wireline technology with the data from different sources helped to make optimal decision.

Traditional well integrity diagnostic includes temperature and passive acoustic data analysis that are associated with high uncertainty. A newer generation of array passive acoustic technology with enhanced sensitivity capabilities was deployed offshore Azerbaijan. A combination of array passive acoustics data, single point temperature and distributed fiber optic data have been acquired during a multi-well campaign. Extensive review of well integrity history, downhole and surface gauge data incorporated with passive acoustic data from arrays of spectral sensors in time and depth domain helped to refine the process and evolve into a unique interpretation methodology.

The comprehensive interpretation accounted for integration of all available static and dynamic data such as: fluids and formation pressure distribution along the borehole, cement bond logs evaluation, annuli pressure and temperature, production and downhole gauge measurements, fibre optic data, temperature and passive acoustic logs. This helped to understand the low scale dynamic events behind the casing and make an informed decision on safe and reliable well operations. The sensitivity of array passive acoustic technology proved successful in detecting subtle acoustic events where conventional methods failed or had limited success. Successful results have been achieved by customizing the logging program using a multiple well evolutionary approach that improved data quality and saved rig time. Interpretation and decisions derived from each well involved multi-disciplinary well review panel sessions with specialists from subsurface & geohazards, drilling & completions, production & operations departments.

Case studies presented in this paper describe the interpretation approach of highly sensitive array passive acoustic sensors in combination with available static and dynamic point and distributed data. The logging program and interpretation approach used in this article could be considered as a basis for future applications in wells with similar design.

Field production constrained with surface facilities on gas handling have to deal with well rates optimization by reducing gas oil ratio of the field production. This means the best way of reducing gas oil ratio on field level is not by closing wells with the highest gas oil ratio but chocking back wells where gas breakthrough occurred and GOR of a well is rate dependent [1].

In this paper, authors modeled and analyzed wells with gas breakthrough in single porosity and dual porosity sector models. The analysis showed single porosity models underestimate severity of gas breakthrough and fail to predict rate dependent GOR of a well in the field.

Also, based on the sector model using machine-learning technique an empirical equation was developed to estimate rate dependent GOR of a well which can be further used in field level production optimization exercise to reach maximum liquid production under gas processing constraints.

Oil production forecasting and well intervention planning require an accurate estimation of the remaining oil in place (ROIP). The problem of ROIP maps generation can be solved using commercial software; however, in the case of large fields, this requires significant computing resources and takes a big amount of time to prepare and adapt the data. Mathematical models for getting a quick solution to these issues have not been sufficiently elaborated. In this work a physical and mathematical model is proposed for building ROIP, oil saturation and water cut maps. The model was used to develop a tool for well stock managing, new wells drilling planning and detection of behind casing fluid flow by comparing the actual water cut of the well with the calculated water cut map.
