Published: September 2021

Após a saída de reclusão da moça púbere, ao longo das brincadeiras rituais, o moça é apresentada e exposta pelas demais mulheresa a vários "predadores" encenados pelos homens. Em um jogo de espelhamentos e inversões, ela é posicionada como uma isca para atrair os predadores e constituir-se como uma armadilha, uma emboscada, na qual o predador seduzido pela possibilidade de sujeitar ou devorar sua presa, só pode cair e ser morto, . O Jara, o branco, é geralmente o último predador a chegar. Figura mais elaborada dessa etapa do ritual, é a única que se torna objeto de chacota das mulheres e das crianças, antes de ser surrada e destruída a pauladas por estas. Este ensaio etnográfico procura analisar o humor e o grotesco no contexto ritual paumari vinculando-o a dinâmica de inversões posicionais que estes operam entre o ponto de vista da presa e do predador, como vetor da aniquilação simbólica do poder e à luz de outra figura ritual, a do parasita. Figura que configura ideal parasitário, onde os patrões acabariam acoados em suas posições dominantes, à mercê da captura e do consumo por seus parasitas. Mas não em um movimento de simples inversão ou anulação de posições, e sim atravessando a relação assimétrica, criando assim uma abertura possível para traçar alguma linha de fuga. Abrindo a possibilidade para que os patrões sejam forçados a assumir a posição de eternos provedores, não só de bens manufaturados, mas de tudo aquilo que se considera indispensável para estar no mundo: parentes, nomes, alimentos, trocas e inimigos.

Published: September 2021

It has been shown that the immune system and mental status are interrelated. Psychoneuroimmunology is a field that studies these two relationships, one of the most studied is the relationship between the immune system and depression. Psychological stress can substantially increase inflammatory activity and increase risk for various health problems. Socioal-environmental conditions trigger biological responses that may lead to an increase in the proinflammatory phenotype which is hypothesized to be a key phenomenon driving the pathophysiology and relapse of depression, as well as the overlap of depression with several somatic conditions such as rheumatoid arthritis, chronic pain, cardiovascular disease, and neurodegeneration. The immune system and depression have a bidirectional link that influences each other. Exposure to chronic stressful situations can cause a maladaptive response by the immune system, which will be involved in the pathophysiology of depression.

Surface Tubing Temperature Transducers Reduce Damage to Downhole Equipment Following a Downhole Gauge Failure
Authors: Zihlmann Livia , Parker Mike , Malsam Luke 
Published: September 2021

Abstract
Downhole sensors gather vital data for the health of an ESP system. Not only do the sensor readings help indicate the flow pattern; they also help indicate further issues such as plugging and degradation of the ESP system. Once a system has grounded on a single phase, sensor readings are lost, and operators must rely on current and frequency for the system to operate efficiently. In unconventional applications of ESP, operators see a small difference between no load, no flow and gas locking conditions. This small difference is due to the de-rating of motors used in order to get the fluid to surface in the severe applications. When the sensor readings typically are lost, operators are no longer able to accurately diagnose the reason for a shutdown. Adding the Tubing Temperature Transducers (TTT's) helps regain an indication of motor temperature along with load on the system. When operators have a drop in the tubing temperature this indicates the system is not able to get as much fluid to surface either indicating gas locking or a no-load condition which results in heating of the downhole system, particularly the motor. All these possible scenarios cause degradation of the ESP equipment and can cause pre-mature failure. If the system is set up with TTT's operators can shut-in the well to avoid extended periods of excessive heating caused by either gas locking or no flow conditions. Single phase to ground conditions occur frequently, however this paper does not address the root cause of a single-phase grounds, rather it addresses what the operator can do to operate efficiently when a unit has grounded out a single phase.

Abstract
The paper reports on the integrated approach for the Brazil Deepwater BC-10 Electrical Submersible Pump (ESP) Operation without Downhole ESP gauges to safety operate the system and surveillance on light to heavy viscosity fluids and two phases, liquid – gas flow. The Electrical Submersible Pumping (ESP) system uses in Brazil are multistage centrifugal pumps for high rate and high boost applications inside a vessel system (caisson) powered with Pressure and Temperature gauges in each caisson, Venturi flowmeter at the discharge of the pump and a Motor POD located at the bottom of the motor that provides internal motor winding temperature (MWT), ESP vibration and Motor External Pressure for safety operation and to help predict ESP performance.
To operate Brazil ESP systems without downhole gauges, an integrated analysis was performed to understand the more important and minimum acceptable variables required to operate the system, substitutions for the essential gauges and bypassed for non-critical gauges for ESP operations. Extended study and analysis were performed to cover in detail each of the alarms to allow running the ESP but maintaining the capacity to protect the system which will be the focus for this paper. All possible scenarios were considering and modelled for TRIP alarms such as out of range MWT, vibration, boost pressure, flow, pressure and temperature at the discharge to ensure capability functions for the critical variables were still available for the safety operation of the system. Low/High flow is a condition that may lead to ESP performance problems, in case of prolonged operation, a correlation from Gasmer Testing (1) based on ESP Boost and VFD current is proposed to calculate pump flowrate for safety operation to avoid ESP failures.
The main technical contributions of this work are the detail approach, modeling and analysis for safety field operation without downhole gauges for predicting pump and motor performance. This study determines the minimum number of acceptance variables required and substitutions, as well variables that can be bypasses for non-critical gauges for ESP operations.
Defining a New Era for Induction Motors
Authors: Escobar Katherine , Radov Maxim , Vasilache Cristina 
Published: September 2021

Abstract
Induction motors have been widely used in the ESP industry for decades. Motor operation, control, and optimization are well-understood topics among providers and final consumers, who strive to get the most efficient electrical machine in the well to reduce power consumption and, consequently, operating expenses.
This paper presents a case study for a newly redesigned induction motor and changes made in its design and construction. A field trial of two wells deployed with the new motor and a comparison with a well deployed with the standard motor are described. Field and simulated data are used to analyze the electrical performance and power consumption. The test results included are from wells in the US Rocky Mountains. Additionally, some of the motors in this test were manufactured with a high-performance thermally conductive and electrically insulative windings encapsulation, which is further discussed in the paper.
The increased efficiency was achieved through an optimized electromagnetic design that helped to reduce the motor total losses. Efficiency gains were measured against standard motor design through laboratory testing, and the result showed 2.2 to 2.5% higher efficiency for the newly developed motor. With the higher power density, the motor length was shortened from 20 to 25% during the field trials, reducing the total length of the string. In addition to the optimization of motor length, the newly redesigned motor generates a lower core temperature when compared to a previous motor of the same length and subjected to the same load. This fact allows the motor to be loaded up to 25% above its nameplate rating, improving the horsepower rating and opening a new era for highly flexible induction motors.
The gathered results showed that the newly redesigned motor provides higher efficiency and lower total electrical power consumption compared to the standard induction motor that would have been used in those applications. Both results were evidenced in controlled laboratory testing and field trials. A further comparison of similar ESP equipment configuration running with former motor versions is also provided, as well as design comparison cases between the expected results of the previous and the newly designed motor.

Abstract
Electrical submersible pump (ESP) is the main artificial lift system in Shushufindi field. These systems besides facing high gas production, high scale and corrosion tendencies, also have to deal with surface fluid handling and electrical power limitations which combined impose challenges to optimize the ESP system. In perspective, the digitalization initiative has been key to integrate data in order to have a big picture of the actual field condition and ultimately to enhance oil production.
Various dashboards have been created using the business intelligence tool to provide real time information. ESP dashboard shows opportunities to optimize the ESP unit by integrating real time and manual entry data to optimize frequency, surface equipment, opportunities for pump upsizing, and re-designing the ESP downhole equipment. The result of this analysis is derived from ESP simulation, nodal analysis, chemical treatment monitoring and real time surveillance of the ESP parameters. Dashboards of water handling, electrical power, and chemical treatment are utilized to support process analysis providing current field status, with also the feedback from operational and engineering recommendations.
Comprehensive real time monitoring resulted in average of 500 bopd less production deferment in the last 12 months as the result of early detection and a proper operational optimization (chemical treatment, gas flaring, and choke optimization) of the unstable wells. Strategic decisions have been executed to ensure the availability of water handling capacity and electrical power for each production station such as stimulating disposal wells, cleaning injection flowlines, and repairing power generations. Up to 3,000 bopd total incremental has been generated in the last 12 months as the result of 17 upsizing operations, optimizing frequency in 68 wells, and optimizing surface equipment in 35 wells. The associated mean time between failures (MTBF) of ESP system has increased over the time from 224 days in 2013 to 674 days in 2020.
Digitalization is a game changer for optimizing the oilfield production and to reduce associated operation risks from features as of real time surveillance, EDGE computing, remote actuation, and big data intelligence. This paper will elaborate in detail on how digitalization can be valuable in optimizing ESP system with a successful case study in Shushufindi field.
First Application of Rigless Electrical Submersible Pump Technology in the Gulf of Mexico

Published: September 2021

Abstract
An operator planned to install ESPs to overcome high water cut and minimize the gas supply risk for a gas lift completion at a platform in the Gulf of Mexico. The platform is an oil collection point and its continuous operation is essential during any rig-assisted interventions. To maintain platform operation, three wells were selected for deployment of rigless electrical submersible pump (ESP) replacement systems to avoid the future use of a workover rig. The challenge was to allow a single-trip ESP deployment using the crane facilities with existing height limitations.
A special surface connection system was designed to allow long ESP sections to connect under pressure at the wellhead. The technology is based on a propriotery system and method of connecting long strings at the surface using a surface lubricator and an adapted deployment stack. The system elements are located between the pump intake and protector seal sections of a standard ESP string that can easily and economically sourced in most locations. This new technology reduces the number of wireline/slickline runs needed, and the system features allow verification of mechanical connection integrity at the surface prior to deployment in the well.
The successful deployment and commissioning of a rigless ESP replacement system in the SM 130 A-26 well in the Gulf of Mexico was completed in October 2019 without incident. Prior to the deployment of the rigless ESP replacement system, it was decided to perform hydraulic stimulation operations to improve the well productivity. This operation resulted in higher than expected well inflow with increased water cut. At the time of writing this paper, the ESP system had recently failed to start due to stuck pump (possibly scale related). Due to the ability to perform a rigless system upgrade for the unanticipated well inflow conditions, the operator is planning for the first rigless replacement of the existing ESP to achieve higher flow rate during the last quarter of 2021.
The successful deployment of the alternative ESP deployment technology demonstrated the potential to improve the economics of the existing production facilities by reducing production deferment, minimizing health, safety, and environment (HSE) exposure; and improving the asset value. This paper discusses the engineered solution and application of the technology required to deploy long ESP strings, modifications required for the specific well conditions, and the lessons learned during the first successful deployment of rigless ESP technology in the Gulf of Mexico. Due to the performance and capability demonstrated in the first successful installation, Talos Energy has recently installed its second rigless ESP replacement system in a recompleted zone and is planning for installing its third system in the SM 130 field in 2022.
Development and Implementation of an Automated ESP Failure Database and Reliability Analysis Platform
Authors: Rabbitt Robyn , Chacin Jesus 
Published: September 2021

Abstract
Identifying and prioritizing reliability improvement opportunities for ESPs, requires proper consideration of hundreds of parameters that include equipment characteristics, operational conditions, and root cause analyses results (Brookbank, E. B., 1997). One of the main challenges is that this data typically resides in a variety of commercial software products used internally by ConocoPhillips Canada as well as various other repositories such as spreadsheets, PDFs and numerous other internal databases and usually needs to be manually integrated for analysis. A second challenge is how to easily and consistently data mine such an extensive dataset.
This paper presents the approach taken, hurdles faced, and results obtained to effectively address both challenges above. First, a failure database was designed to automatically capture time continuous data flows from various data streams, many of them flowing from commercial software tools but also some via email. To address the second challenge, an advanced visualizations and data analytics layer was developed to mine the database, in order to estimate various reliability and optimization metrics, uncover trends and generate forecasts instantaneously.
Our solution was to create a unique cradle to grave ESP tracking and visualization integrated system, supporting the complete ESP reliability engineering workflow. It includes vendor to operator ESP equipment data transfer, database and nomenclature structure, operational data capture during the life of the ESP and RCA results data capturing via a 3rdparty low-code application development platform (LCADP). A visualization layer for data analytics and reliability metrics was seamlessly integrated through the use of a commercial software analytics and visualization platform (AVP).
Results to date are very encouraging, both in terms of efficiency gains and quality of analysis and results. Consistent use of reliability metrics when used by different members of the production team have been achieved.
Lessons learned during the development and specific examples on how the system is being used are presented, including AVP based trend visualization and failure forecast estimations. Key examples of the value captured with this Failure Database and Visualization Platform are also presented, including improved data quality, increased analytical capabilities and enhanced understanding of reliability improving options. The overall net benefit being optimized ESP life cycle costs.
This development has the potential to be easily extended to other downhole production equipment such as fiber optic strings, liners, flow control devices, steam splitters and other artificial lift methods utilized in SAGD such as progressing cavity pumps.
