AbstractIn this work, we present the development and deployment of high activity liquid polymer that improves logistics for field deployment in supply chain constrained locations. Such polymers show superior performance in terms of dissolution times, increased neat polymer stability, and improved injectivity during tertiary oil displacement in comparison to traditional emulsion polymers. The initial screening process comprised of testing for viscosity yields in the desired brine, filterability, and long term injectivity corefloods in surrogate rocks. Additional tests included long term aging studies with contaminants to measure shelf life of the neat polymer. Finally, yard scale tests were conducted to identify mixing configuration and system pressures for optimal mixing conditions to scale up for field deployment. The liquid polymer developed for this application shows superior performance with rapid viscosity yields both in lab scale and yard scale mixing tests. Long term injection shows good injectivity (stable pressure for greater than 25 PV injected). Aging tests demonstrated the improved shelf life and higher stability of the neat material in the presence of iron. Application of mechanical shear and imposing temperature vaiations to the neat polymer did not affect the quality of the diluted polymer solution. QA/QC of field supplied batches indicate consistent quality of commercial scale polymer production thus demonstrating the applicability of liquid polymer for piloting at the field scale. The developed liquid polymers improve upon the limitation of traditional emulsion polymers with higher activity, better injectivity, faster dissolution times and better neat polymer stability. These features combined lead to enhanced product performance thus further de-risking polymer flooding in logistically challenging environments.

Published: February 2022

Abstract
An innovative BHA was designed to fit slim extended reach wellbore profiles. Precise BHA design was essential to reach the bottom of the well with a scrapper and circulate to clean the hole efficiently for enabling fracking operations with Plug & Perf technology to be performed in extended reach horizontal wells in Bahrain.
Plug & Perf operations for multistage fracking required to run plugs through a cased extended horizontal section with an internal diameter of 4" to isolate the different stages to be stimulated. The max OD of the plug was 3.625 in leaving a marginal clearance between the plug and the casing, making hole cleaning the primary risk to deal with.
For hole cleaning it was important to design the slim BHA with a maximum OD of 3.125 in and ensure reaching bottom. Torque & drag simulations were run using Extended Reach Architect software specialized for drilling ERD wells. This innovative use of the program required creating a fictional section in the well schematic where the new BHA design was simulated. During the execution phase, the simulations proved their accuracy while pointing out the depths where the string weight is lost, and a change in pipe diameter and weight is crucial to continue running in hole.
This unconventional BHA design met not only the technical requirements, but also the logistics challenges coming from the current working pipe inventory. The team looked for alternatives by designing several BHA scenarios, changing the position, amount, weight, and diameter of pipes to be used.
Innovation and accurately applied well engineering created a BHA design process that unlocked the possibility to perform the completion operations of ERD horizontal wells. Ultimately 6 ERD wells were successfully prepared for fracking operations. The implementation of this BHA design workflow decreased the number of clean out runs from 5 attempts to 1 successful run in every well, therefore reducing the operational time by 12 days per well, in overall saving 75 days. Helping to bring oil production faster in Bahrain.
First Successful Deployment of Nonmetallic Casing Strings: A Case History

Published: February 2022

Abstract
For the first time, two different sizes of nonmetallic casing strings were installed in water wells to cover shallow potable aquifers. This paper describes the reasons for deployment, planning and design, logistics, operational challenges, lessons learned, and the way forward for this newly deployed technology.
In the initial stages of the project, fiberglass-reinforced thermoset resin (RTR) pipes manufactured locally were evaluated in terms of ratings, dimension, and method of connection and feasibility for downhole applications. Two nonmetallic casing strings, 19.7″ and 11″, were selected to be run in hole. Design consideration also included compatibility with available casing running and handling tools to ensure safe and efficient field handling and running. At this stage, carbon steel casings were still needed to connect the nonmetallic casing to the surface wellhead equipment and to the float equipment at the bottom of the string. Specially designed crossovers were manufactured and tested prior to enabling combination of nonmetallic and carbon steel casing. All manufactured casing joints and crossovers were tested based on the best available criteria for the nonmetallic industry.
Different challenges were encountered in the design stage, such as overcoming the buoyancy force while running and cementing the nonmetallic casing, all of which to be tackled. Cement slurry design and casing accessories were modified based on the simulations scenarios that were run. These designs were subsequently modified in response to issues, i.e., total losses, encountered while drilling.
Successful evaluation of the nonmetallic casing deployment was conducted from multiple aspects, including running efficiency, casing wear, and cement quality. Drillpipe protectors were utilized to reduce the possible casing damage due to wear.
The nonmetallic casing joints were connected through crossovers to a top metallic casing and float equipment at bottom. Both casing strings were successfully run to depth and cemented in place.
Both casings were pressure tested successfully after performing the logging jobs that indicated the level and quality of cement pumped around the strings. Logs showed no considerable change in both nonmetallic casing thickness.
The well was completed with open hole, tested and flowed naturally to surface. A conventional power water injector wellhead was installed before release.
The design, review and assessment processes, as well as several lessons learned from the first ever deployment of the nonmetallic casing in a water supply well, are the key takeaways from this paper.
Langmuir Parameters Prediction: New Insights into the Porosity of the Nanoporous Media of Organic Media of Organic-Rich Shale

Published: February 2022

Abstract
Shale is a type of unconventional reservoir with a significant potential for storing natural gas attributed to its ability to host hydrocarbons as both free and sorbed phases. However, modeling this multi-physics storage capacity requires redefining some macroscopic parameters such as the porosity to capture the adsorption behavior and pore compressibility, which changes over the entire production life of the asset. Besides, a distinct confining stress phenomenon occurs in a reservoir with a different faulting system and degree of stress heterogeneity. Such mechanisms at nanoscale are complex and difficult to isolate through conventional experimental approaches. Alternatively, computational frameworks like molecular simulation can provide a proxy to accurately describe such intervening mechanisms. The study starts with recreating realistic organic matter structures from a given macromolecule kerogen unit using a molecular dynamics protocol. The created structures were subject to adsorption analysis and mechanical properties assessment while tracking the changes in porosity and pore size distribution. The analyses were used to redefine the porosity considering the adsorption behavior, mechanical properties, pore, and confining pressures. Furthermore, a correlation between stress-induced porosity and Langmuir quantities was developed to predict the Langmuir parameters. The logarithmic function-based model showed that a 33.3% change in stress-dependent kerogen porosity could result in a Langmuir amount, pressure and maximum adsorbed gas density variation of around 100%, 100%, and 50% respectively. Consequently, nanoporosity influence on Langmuir parameters should be critically understood as it plays a significant role in adsorbed gas storage and molecular transport processes in organic-rich shale.

Одной из задач, стоящих перед нефтяной промышленностью, является устойчивое обеспечение потребностей республики в углеводородном сырье, решение которой существенно зависит от ускорения научно-технического прогресса отрасли. Это предполагает увеличение уровня добычи нефти и попутного газа не только за счет ускоренного ввода в разработку новых месторождений, но и широкое использование прогрессивных методов воздействия на пласт, обеспечивающих увеличение дебитов скважин на разрабатываемых залежах.Одним из основных методов повышения эффективности добычи нефти является физико-химическое воздействие на призабойную зону пласта с целью увеличения ее проницаемости и обеспечения связи забоя скважины с пластом, среди применяемых растворов наибольшее распространение получила грязевая кислота и гидрофобные кислотные эмульсии на её основе.
One of the tasks facing the oil industry is the sustainable provision of the republic’s needs in hydrocarbon raw materials, the solution of which depends significantly on the acceleration of the scientific and technological progress of the industry. This implies an increase in the level of oil and associated gas production not only due to the accelerated commissioning of new fields, but also the widespread use of progressive methods of stimulating the formation, ensuring an increase in well flow rates in the developed deposits.One of the main methods of increasing the efficiency of oil production is the physicochemical impact on the bottomhole formation zone in order to increase its permeability and ensure the connection of the wellbore with the formation; mud acid and hydrophobic acid emulsions based on it are the most widely used solutions.

Na Zona Costeira Sul do estado da Paraíba (ZC-Sul/PB) ocorrem os maiores índices pluviométricos do estado. As bacias hidrográficas na região apresentam rios perenes e, por conseguinte, há diversas captações de água para alguns usos. Ademais, há preocupação com a vulnerabilidade ambiental, referida à perda de solos, decorrente do uso e ocupação. A existência de informações divergentes acerca das tendências de séries de precipitações na região, anuais e das quadras chuvosas (QC), motivou a elaboração deste trabalho relativo a uma investigação sobre a existência de tendências. Foram realizadas verificações sobre a aleatoriedade dos valores das precipitações componentes das séries pluviométricas, o que poderia indicar oscilações e tendências. Os métodos utilizados foram os não paramétricos de Mann-Kendall, para verificar se há tendências positivas e negativas das séries pluviométricas, e o teste de frequência de fases de Wallis e Moore, buscando examinar se a sequência dos elementos da série é aleatória, considerando o nível de significância de 5%. Os resultados não revelaram haver tendências estatisticamente significativas nas séries temporais de precipitação dos postos estudados. Similarmente, o exame dos arranjos dos valores das séries indicou aleatoriedade nas séries de precipitação, do que se presume não haver tendências ou periodicidades.Palavras-chave: séries temporais de precipitação, mudanças climáticas, análises de tendências. Trend and periodicity analysis of pluviometric series in the South Coastal Zone of the State of ParaíbaA B S T R A C TThe highest rainfall indexes in the state of Paraíba occur in the Southern Coastal Zone (ZC-Sul/PB). In the watersheds of the region several perennial rivers occur and there are several abstractions of water for diversified uses. Furthermore, thre is the concern with environmental vulnerability, referring to soil loss, arises mainly from use and occupation. The existence of divergent information about the rainfall series trends in the region, annual and rainy season (QC), led to the elaboration of this work concerning an investigation in the ZC-Sul/PB about the existence of trends. Thus, checks are made on the randomness of rainfall values component of rainfall series, which could indicate oscillations, as well as trends. The Mann-Kendall nonparametric method was used to check for the existence of positive and negative rainfall trends and the Wallis and Moore phase frequency test to examine whether the sequence of the series elements is random, taking into account the significance level of 5%. The results did not reveal statistically significant trends in the rainfall series of the studied stations. Similarly, examination of the arrangement of the series values indicated randomness in the precipitation series, and it is assumed that there are no trends or periodicities.Keywords: precipitation time series, climate change, trend analysis.
