De Soweto à Ceilândia: siglas de segregação racial
Authors: Lemos Guilherme Oliveira 
Published: January 2018

A proposta desse trabalho é pensar relações comuns ou, pelo menos, aproximadas sobre os processos e os instrumentos de segregação urbana racial, generificada e social nas cidades de Soweto (Joanesburgo - África do Sul) e Ceilândia (Distrito Federal - Brasil) durante as décadas de 1950 e 1970. Para tanto, comparamos os dois processos de remoção das populações dos centros para as periferias e a (re)invenção dos tipos corpóreos (“candango”, “black”, “african”, “coloured”) destinados a ocupar os limites da não-vida, ou seja, as chamadas cidades satélites. Metodologicamente a pesquisa, de caráter inicial, fez-se através da análise indiciaria e comparativa de documentos oficiais, relatos orais e bibliografias referentes às duas cidades. A aproximação analítica/histórica entre esses casos se tornou possível através do conceito de necropolítica e da correlação entre escravidão, colonialismo e apartheid: três eventos imaginados historiograficamente como distintos, mas onde a dissociação do ser ao direito de sua própria vida rompem as barreiras do tempo e, no caso Soweto-Ceilândia, as fronteiras do Atlântico.

Estamos em meio a um acontecimento histórico que ainda merecerá muitas análises por nos demandar uma reflexão cuidadosa e consequente que não nos capture em meio a uma dispersão construída milimetricamente pela mídia que divide “baderneiros” – com suas pará-frases promovendo indistinções e sobreposições – e “manifestantes pacíficos” – um monobloco que apaga na unidade. Tão simples quanto. Mas é uma dispersão que toca também o real da língua e da história (Pêcheux e Gadet, 2004). Buscar flagrar este real (ORLANDI, 1999) vem sendo o projeto acadêmico-científico-político deste Laboratório de Estudos Urbanos que publica, desde 1995, a revista RUA. Uma revista multidisciplinar que procura fazer circular artigos que toquem, em suas especificidades disciplinares, teóricas e epistemológicas, as diferentes formas de significar e significar-se no espaço urbano. É o que estes onze artigos que compõem a seção Estudos, o vídeo apresentado na seção Artes, e a resenha proposta sobre o Cypherpunks fazem acontecer neste primeiro volume do número 19 da revista RUA.

Published: January 2018

Summary
For accurate determination of asphaltene flow assurance, the importance of asphaltene-onset pressure (AOP) as direct information from live oil is undisputed. For this purpose, the standard has been to use a single-phase bottomhole sample, even though this is expensive. This fluid sample stores information most closely representing in-situ asphaltene conditions. Because of its costly collection, the handling and examination of such samples are conducted carefully to avoid inconclusive results and/or wastage; however, unexpected experimental difficulties sometimes result in the failure of AOP detection. In our AOP-measuring experience, the most modern method—laser light scattering (LLS)—has been applied because of its convenient and quick procedure. Our measuring equipment consists of a solid detection system (SDS) that uses LLS to determine AOP using the power-of-light-transmitted (PLT) function. In addition to the SDS, the apparatus also consists of other simultaneous measuring functions: high-pressure microscopy (HPM), which can be used to visually observe asphaltene particle count and size, and a densitometer and viscometer to investigate fluid kinetics. In this work, the HPM and viscometry measuring functions were demonstrated as useful supporting techniques to determine AOP in cases when SDS PLT results cannot be used alone. This work demonstrated that data acquisition should be maximized and as much information as possible should be obtained from the costly sample. AOP interpretation that is based on each type of data can be aligned in an order related to the asphaltene particle size and growth because the detection limits of each measurement are reflected in the AOP interpretation. In summary, comprehensive interpretation can achieve a higher-quality estimate of AOP: Different measurements give different interpretations that can be used in a synergistic manner.
Accurate Modeling of Surge and Swab Pressures of Yield Power Law Fluids in Concentric Annuli

Published: January 2018

Abstract
Accurate numerical modeling of surge and swab pressures in concentric annuli is proposed. The numerical scheme is developed for the laminar flow occurring during the drillstring axial movement. The model incorporates Yield Power Law (YPL) fluids, which is a good representation of the most of the drilling fluids. A commercial computational fluid dynamics (CFD) package is used to validate the developed numerical model. Also, the mathematical model and CFD analysis are compared with the existing models from literature.
A high order finite difference numerical model is developed that accurately captures the physics of laminar flow due to surge and swab phenomena in concentric annuli. The numerical scheme is prepared such that it accounts for both Newtonian and non-Newtonian fluids. YPL model is incorporated in the proposed scheme, and it accurately estimates the drilling fluid behavior in both high and low shear rates. CFD analysis is conducted using a commercial software to validate the accuracy of in house developed numerical model. The velocity profiles across the annulus are compared in order to verify the precision of the model.
The proposed model for the surge and swab pressures is more accurate than narrow slot approximation model which is most commonly used in the drilling industry. With this proposed modeling, the physics of surge and swab pressures are better captured, because it accounts for the effect of curvature in annular geometries. The model is well-validated with the CFD analysis and the velocity profile comparison of the numerical solution and CFD analysis yields less than 5% average absolute percent error. With this work, dimensionless velocity profiles are presented which better explain the flow during surge and swab in concentric annuli, while the inner pipe is reciprocating in steady-state.
Pulling out or running tubulars in the vertical section, or running casing with centralizers approximates the position of tubular to concentric. It is very important to accurately calculate these pressure losses to avoid fracturing the formation or having an influx from the formation. Therefore, CFD analysis and mathematical modeling of surge and swab pressures presented in this study has potential to optimize the tripping operations that will help avoid hole problems.
Proppant Performance in Marcellus Shale Fractures Under Experimental In-Situ Stress Conditions
Authors: Elsarawy Ahmed M. , Nasr-El-Din Hisham A. 
Published: January 2018

Abstract
Hydraulic fracturing is a key treatment for economical production from shale formations. High surface pressure is used to fracture the formation, and proppant is pumped to prevent fracture closure after the pressure is removed. The ability of proppant to maintain high fracture width and permeability controls the flow of the hydrocarbon fluids towards the wellbore, and, hence, the behavior of different proppants at in-situ conditions is critical to the success of fracturing operations in shale formations. The objective of this paper is to experimentally evaluate the performance of two widely used proppants in Marcellus shale at elevated stress conditions.
A proppant-crushing test between two samples of Marcellus shale was performed to evaluate the proppant performance at different closure stress values up to 10,000 psia. Two types of proppants were tested: sand and sintered bauxite at different concentrations. This work used a digital microscope to measure the width of the fracture at each closure stress; a series of photographs of the propped fracture were taken, and an image analysis software was used for fracture width measurements. The amount of crushed proppant and induced formation fines due to embedment were also quantified after each test.
The results indicate that with partial monolayer proppant, both proppants experience a significant reduction in the fracture width at elevated closure stresses, reaching as high as 48% at 10,000 psia. Proppant physical properties were found to affect the initial fracture width even though the proppant concentration was the same. The use of multiple layers of bauxite proppant reduced the loss of fracture width to 14% at 10,000 psia closure stress. Results reveal that sand proppant shows a high degree of crushing at 0.05 and 0.25 lb/ft2 proppant concentrations. On the other hand, the use of bauxite results in a higher amount of formation fines due to proppant embedment, which could cause severe damage to the fracture conductivity.
The paper contributes to the understanding of how proppants behave at in-situ conditions of shale hydraulic fractures. Results can be used to optimize proppant and fluid selection, and reduce the sources of damage to fracture conductivity to maximize well productivity.
Drilling Control Rooms of the future
Authors: Botnan Espen 
Published: January 2018

Abstract
The driller, or well execution engineer, as some call it, is now responsible for a bigger part of the overall drilling process as automation and mechanization on rigs increases and the market moves toward performance-based, as opposed to day-rate, contracts. More information must now be absorbed and analyzed; hence, the driller is more important for safe and efficient drilling processes. Due to this, it is more critical than ever to ensure that the well execution engineer has an optimal working environment. This paper outlines several new technologies to help ensure that the working environment and process is more streamlined and comfortable.
Several innovations in the driller's control room (DCR) are outlined, such as new window and display technology, as well as new sophisticated communication systems.
Additionally, new drilling software is developed to ensure constantly high performance through autopiloting.
Overall, these new products improve the working environment and overall efficiency, which also results in more cost-effective well construction and safer operations for the rig crew.
Perforating Vertical Smart Well Completions Using Tubing-Conveyed Perforating Gun Assemblies: Case History
Authors: Wood Stuart , Comb Lachlan , Singh Mandeep Kuldeep , Lavery Joshua , Biddle Matthew , Hyatt Paul 
Published: January 2018

Abstract
Smart well completions include downhole gauges, sliding circulation valves, open/close safety valves, control lines, and fiber cables or a combination of these. One method for deploying this downhole equipment is achieved by affixing it to the outside of the casing and permanently cementing it in place; however, a challenge with external-casing equipment is helping to prevent damaging the installation if perforating is the chosen method to establish effective communication between the wellbore and formation. This challenge is further magnified when the well is drilled near-vertical and run on the outside of a large-diameter casing.
This paper discusses the execution of an engineered design of service to perforate a 7-in. diameter production smart well completion using 4 5/8-in. tubing-conveyed perforating (TCP) gun assemblies. As part of the completion design, the TCP gun assemblies were hung below the bottomhole assembly (BHA). A fiber-optic (FO) package was run external to the casing, and the well had a deviation less than 5°, preventing the use of high-side logging tools.
Various options, discussed later in this paper, were considered to locate the azimuthal orientation of the fiber cables, including a new-to-market technology tool. Ultimately, a method was devised to engineer an ultrasonic logging tool to be deployed in conjunction with a north-finding gyroscope tool to accurately determine the location of the external-casing equipment. TCP guns were then hung below the tubing string, which included a fixed-point orienting sub that could be used to confirm the direction of all the planned perforations. To achieve operational and economic objectives, the TCP assembly was dropped to the bottom of the well so that the well could be immediately placed on production without killing the well or retrieving the spent perforating guns.
The well was successfully perforated without damage to the external-gauge equipment, showcasing that collaborating with the operator, and understanding their value drivers, led to an engineered solution that maximized the asset value of the well.
Curing Losses in Vuggy Carbonate Formations
Authors: Alshubbar G. D. , Nygaard R. 
Published: January 2018

Abstract
Despite the preventive wellbore strengthening (WBS) approach, lost circulation (LC) followed by well control events have been encountered where thousands of barrels of mud were lost to a formation resulting in long periods of shutdowns. The aim of this paper is to identify the LC mechanism in this formation and propose conventional loss circulation materials (LCM) treatments that stand a higher chance of curing the losses based on experimental investigation of irregular shaped openings to mimic vuggy porosity.
A review was conducted to identify the depositional and diagenetic processes for the "A" formation. The study concluded that touching vugs type of porosity, created through massive dissolution, is the main LC mechanism. To propose a treatment, four stainless steel disks with different irregular opening shapes and sizes, to mimic the reported vugs in the "A" formation, have been developed. As vugs reportedly have wider openings than what anticipated in fractures, an equivalent vug diameter was defined as the maximum width along the longest vug axis. As an initial screening stage, these disks were used in a low-pressure LCM apparatus (LPA) with different LCM additives to identify if the concentration and particle size distribution (PSD) are able to form a seal. The integrity of the seal was then investigated using a high-pressure fluid loss apparatus.
Synthetic rubbers and calcium carbonates were specifically sized to meet the needed PSD and effectively initiated a seal. Other commercially available products, such as synthetic & acid soluble fibers and reticulated foam, were successful when mixed with other LCM to meet the need PSD. Several combinations of the LCM additives have been successfully identified to form a seal at high pressure differential reaching up to 3000 psi. Such a seal integrity would make a very good potential candidate treatment for "A" formation.

Abstract
Today's data is tomorrow's oil and gas. Only the data can tell us right or wrong, but not the experience or feel. The real-time logging data conforms to the 6V features of the Big Data (Velocity, Variety, Volume, Veracity, Visualization and Validity). As a result, the drilling operations efficiency is significantly improved by the Big Data mining of real-time logging.
The Big Data mining helps recognize the drilling operations automatically and identify the invisible non-production time (INPT). Firstly, the real-time logging data is acquired by the comprehensive logging unit. Secondly, the drilling operations are recognized by applying restrictions to drilling parameters. Thirdly, the daily time and the total time is breakdown based on the above logging data and operations categories. Finally, the INPT is identified by setting the target value based on the Big Data mining and learning curve.
The savings potential, which is determined by the average and target, is critical to improve the operations efficiency. On one hand, the Normal Distribution is established by setting the specific operation time (such as slips connection time, etc.) to the X-axis and the operation count to the Y-axis. The average and covariance of the Normal Distribution is calculated. On the other hand, the target value is based on the Big Data mining by the Bayesian network model and the total-time learning curve of batch wells. As a result, the real-time drilling efficiency can identify the best-performing operations, crews and rigs. The crew-based operational performance comparisons are effective to identify the best-performing crews and to indicate where best to focus training and crew supervision efforts in the future. And the real-time drilling efficiency can measure the rig performance in order to make INPT visible. At last, the real-time drilling efficiency yields cost and time savings on both deep-water and complex wells. The method is successfully applied to BD gas field in Indonesia which is HTHP and LW oil field in South China Sea which is in deep-water. Application shows the INPT represents about 32%.
The Big Data mining of real-time logging significantly improve the drilling operations efficiency, detect and minimize the INPT. As a result, the Big Data mining yields cost and time savings for tomorrow's market.
