Authors: Cunha Nascimento Dahan Da , Rocha Silva Cristiane , Prestes Jonato
Published: March 2019

Procedimentos de comparações múltiplas ou post hoc são fundamentais em pesquisas no âmbito na saúde, esporte, educação e lazer. No entanto, a escolha do teste mais adequado por praticantes de estatística na área das ciências da saúde ainda gera dúvidas. O teste utilizado deve promover proteção contra o erro do tipo I, considerar o número de comparações ou grupos e deve ser conservador. No entanto, se o procedimento é muito conservador, diferenças genuínas podem ser negligenciadas ou aumentar o erro do tipo II. Com isso, o objetivo da presente revisão é apresentar um guia com mais de dez diferentes testes de comparações múltiplas e sugestões para o uso mais adequado desse tipo de estatística

THE OVERCOMING OF DISCRIMINATION AGAINST WOMEN AND PROTECTION OF THEIR RIGHTS DY INTERNATIONAL ORGANIZATIONS (1945-1967 YEARS)
Authors: Vlasova А.
Published: March 2019

"Women's issue" in French society remains unresolved after granting of voting rights to women which actually made them equal with men. Discrimination on the basis of gender in France took place in traditional thinking, the main thesis of which was the stereotypical perception of women as second-rate persons and weak individual in the family and society. So, women needed protection and approval of their rights. International organizations took the responsibility to protect women from discrimination and pursue policies to improve conditions of their life. Several declarations, conventions, pacts were adopted by the Organization of the United Nations and the International Labour Organization. They have been directed to change the relationship between members of society by providing equal rights in all spheres of life regardless of their gender, nationality, religion, property belonging or any other possible human characteristics. Formation of the French public policy conducted in accordance with the decisions of international organizations, in which she was a permanent member. Overcoming discrimination policy of women was aimed for destruction stereotypical attitudes that concern the role of women in French society, economic, social, political and daily life.

Authors: KARADAĞ Hasan , EROĞLU Emine , KIRILMIŞ Cumhur
Published: March 2019

In this work, effects of concentrations ranging
from 0 to 500 mg/L of some 2-aminothiazole derivatives such as
4,4’-(disulfanediylbis(methylene))bis(thiazol-2-amine) dihyrochloride (DMTA)
and 2-amino-4-(chloromethyl)thiazole hydrochloride (ACT) on glutathione
reductase from baker's yeast (Saccharomyces
cerevisiae) (GR) were investigated. With exposure of 25, 50, 100, 250 and
500 mg/L concentrations, % GR activity changes were calculated as -5.29 ; -3.85
; -2.40 ; -6.73 and -10.58 in DMTA applications, while these changes were
calculated as +0.98 ; 0.00 ; -0.49 ; -2.45 and 0.00  in ACT applications, respectively. This work
indicated that there was a slight decrease in GR activity with the increase of
DMTA concentrations and there was no significant change in GR activity with the
increase of ACT concentrations.  But
according to control activities, no statitistical changes were observed in GR
activities with exposure of these 2-aminothiazole derivatives (p > 0.05,

Curcumin-Loaded Bio-Based Electrospun Polyurethane Scaffolds
Authors: HORZUM POLAT Nesrin , ARIK KINALI Nehir
Published: March 2019

Polymeric
electrospun fibers present well-design scaffolds for wound healing
applications. Here, the fabrication of biobased polyurethane (PU) blend fibers
containing curcumin (Cur) was reported. Not only polymer concentration but also
curcumin concentration affects the morphology, diameter, and contact angle
values of the fibers. Morphological investigations revealed that the diameter
and hydrophilicity of the PU fibers increased upon addition of curcumin. Effect
of process parameters (applied voltage, flow rate, and tip-to-collector
distance) on the average diameter and the hydrophilicity of the PU and PU/Cur
fibers were examined. Optimum conditions to obtain uniform and bead-free PU/Cur
fibers were determined as 12.5 kV, 1
mL/h, and 17 cm. This study demonstrates that the electrospinning process
provides a simple way of obtaining bioactive agent loaded fibrous scaffolds, as
well as contributing to a better understanding of the effect of process
variables in the fabrication of PU/Cur blend fibers for wound healing
applications.

Assessment of Gluten-Free Food Sourced Heavy Metal Accumulation for Celiac People
Authors: SOYLAK Mustafa , DURAN Ali , YILMAZ Erkan
Published: March 2019

This paper shows an evaluation to the study of
some heavy metals in certain gluten-free foods for celiac people marketed in
Kayseri, Turkey. The concentration values of Cu, Mn, Co, Pb, Cr, Zn, Ni, Cd and
Fe in eleven different gluten-free food samples are reported. The
determinations were carried out by flame atomic absorption spectrometry after
wet digestion method. The average metal concentrations of all the analyzed
samples were determined in the range of 0.45-5.12, 1.84-12.2, 1.29-22.5,
0.60-3.01, 0.08-0.18, and 4.61-79.6 mg kg-1 for Cu, Mn, Zn, Ni, Cd and Fe, respectively. The
accuracy of the method was confirmed by the analysis of a standard reference
material (SRM 1570a Spinach Leaves). Metal pollution index was also calculated
to examine the overall heavy metal levels in all analyzed samples. The
concentrations of the analyzed metals are equivalent to 7.55-35.3% compared to
the daily intake offered by international decision authorities. For this
reason, the nutritional quality index for gluten-free food products with
respect to all the metals seems to be relatively low.

Authors: Kuzminykh Tatyana U. , Borisova Vera Yu. , Nikolayenkov Igor P. , Kozonov Georgy R. , Tolibova Gulrukhsor Kh.
Published: March 2019

Hypothesis/aims of study. Myometrial relaxation and contraction require synchronous cellular interactions. At present, it has been established that the coordination of myometrial contractile activity is carried out by a conduction system constructed from gap junctions with intercellular channels. There are no clinical data on inhibiting (nitric oxide synthase) and activating (connexin-43) factors of uterine contractile activity in the myometrium during pregnancy and parturition in the published literature. This study was undertaken to measure the expression levels of nitric oxide synthase, adhesion molecules CD51, CD61, and connexin-43 in the myometrium during pregnancy and parturition; and to assess the role of inhibitory and activating factors in the development of uterine contractile activity.
Study design, materials and methods. An immunohistochemical study of myometrial biopsy specimens obtained from the lower uterus segment during cesarean section was performed in eight women with a full-term physiological pregnancy, in another eight individuals in the active phase of uncomplicated parturition, and in eight patients with uterine inertia. Integrins (CD51 and CD61 proteins) were used as markers of cell adhesion. Localization and the number of intercellular contacts were assessed by measuring the expression level of connexin-43, with the intensity of oxidative processes assessed by nitric oxide synthase activity.
Results. In the myometrium, in the active phase of physiological parturition, a three-fold increase in the expression of activating (CD51, CD61, and connexin-43) factors of uterine contractile activity and a five-fold decrease in that of inhibitory (nitric oxide synthase) ones occur compared to those in full-term physiological pregnancy.
Conclusion. In the pathogenesis of uterine inertia and resistance to labor induction, an important role is played by the decreased expression of adhesion molecules (CD51, CD61) and connexin-43 and the increased expression of nitric oxide synthase in the myometrium.

Published: March 2019

Purpose: Local anesthetic agents have been widely used in dentistry for several decades. Administration of local anesthetics at body temperature has been reported to shorten the onset time and reduce pain during injection. The aim of this study was to compare the effect of the local anesthetic at body temperature and room temperature before wisdom tooth extraction in terms of injection pain and onset of anesthesia.Materials and Methods: Forty-six adult patients, who were undergoing wisdom tooth extraction, participated in this split-mouth study. To the one side of the patient’s jaws warmed anesthetic solution and to the other side anesthetic solution at room temperature was injected.Results: There was no statistically significant difference between two groups. Mean onset time of anesthesia and VAS scores during injection were similar for room temperature and warmed anesthetic solution groups. None of the patients exhibited any complications during and after injection.Conclusion: Further studies, which include large number of samples, may indicate the effectiveness of warmed anesthetic especially with regard to reducing pain during injection.
Prevalence and determinants of breast self-examination in Karabuk, Turkey
Authors: KARAHAN Nazan
Published: March 2019

Purpose: The aim of this study was to evaluate the awareness of women about breast self-examination and to examine the factors affecting thisMaterials and Methods: This was a descriptive and analytical study, conducted on female patients presenting at the Karabuk University Training and Research Hospital between 15 October 2015 and 15 February 2016. The study sample comprised 483 females willingly participating, with no cognitive problems and no diagnosis or treatment of breast cancer and no history of breast surgery. Results: While 63.8% of the participants stated that they knew about breast self-examination, only 8.5% performed it regularly and 50.9% stated that they examined themselves occasionally. When the relationship between status of performing breast self-examination and variables were examined, a significant difference was observed in respect of age, level of education, employement, marital status, history of breast cancer in family/friends. It was determined that women of a younger age, with a higher level of education, fewer children and who were employed, had greater knowledge of breast self-examination and application rates, whereas the majority of those who did not perform breast self-examination were worried that they would get breast cancer and thought that they would not be able to detect a mass in their breast.Conclusion: These findings indicate that there is a need for widespread community-based education and the target group for this education should primarily be older women, with low education, a greater number of children and who do not work outside the home.

Este documento muestra una medición cuantitativa de corte descriptivo, del análisis de datos secundarios suministrados por las fuentes de información oficiales propuestas por el CONPES 140 y que responden a una serie de 58 indicadores no aleatorios de medición socioeconómica de los Objetivos de Desarrollo del Milenio (ODM) para el Departamento de Sucre (Colombia). Luego de explicar la relevancia del estudio y otras disposiciones, se muestran los resultados, ODM por ODM, y analizados frente a las metas esperadas. El principal hallazgo es que, gran parte de los indicadores propuestos no tienen una herramienta de medición precisa al nivel sub nacional, en consecuencia, su gestión no puede describirse estrictamente ni contrastarse con los resultados nacionales; hasta tanto ajustar las métricas e indicadores originales. Finalmente, se plantea discusión sobre la pertinencia de implementar la nueva Agenda de Desarrollo Sostenible 2030, cuando a 2018, no se tienen resultados actualizados sobre fenómenos trascendentales como la pobreza y la cobertura de necesidades básicas insatisfechas; así como tampoco se conoce el desempeño la participación de las regiones en los resultados ODM nacionales, publicados en 2015.

Authors: Jindal Sanchali , Garg Preeti
Published: March 2019

Background: Self medication is an important component of primary health care. It involves treatment of common ailments on ones own initiative or on the advice of a pharmacist. With the easy accessibility to information regarding use of drugs, there is an alarming increase in the self medication practices. Medical students, during their course of study gain considerable knowledge of drugs and it may have an influence on their self medication practices. The present study was designed to gather the knowledge, attitude and behavior of medical students towards self medication and whether an increased knowledge of drugs further promoted self medication.Methods: A questionnaire based study was carried out on students of 2nd semester students relating to their knowledge, attitude and practice of self medication.Results: Though the knowledge regarding drugs is quite comparable in both the first and third year medical students, 39% students in group A took the medicine without doctors’ advice in the last month whereas 58% 5th semester students in group B did the same.Conclusions: The frequency of self medication is higher among third year students as they believe that the medical training makes them capable enough to self medicate easily without any harm. Hence, there is need to promote rational self medication practice to bring awareness about irresponsible self medication.

Authors: Megreya Ahmed Maher , Elgammal Ahmed S. , Shahin Mahmoud A.
Published: March 2019

Background: The use of splenic ﬂexure mobilization (SFM) for rectal cancer surgery is still controversial. SFM includes division of the splenocolic, phrenocolic, gastrocolic and pancreaticomesocolic ligaments, which is time-consuming. The aim of present prospective study of low anterior resection in case of cancer rectum was to compare splenic ﬂexure mobilization (SFM) carried out by an extended medial approach with that by a lateral approach.Methods: A prospective study was carried out in General Surgery Department, Menoufia University, Egypt between October 2017 and December 2018. Patients were allocated randomly into two groups in which first group (group A) allocated to medial mobilization of splenic flexure and the second group was allocated into lateral approach of splenic flexure. The extended medial involved continuing the medial to lateral approach upwards to enter the lesser sac over the pancreas, thus permitting detachment of the splenic ﬂexure. However, lateral approach involves dissection of retroperitoneal fascia.Results: Thirty patients, including 20 undergoing a lateral SFM and 10 an extended medial SFM, were evaluated. Mean number of lymph nodes in lateral and medial approach are (17.7±5.6, 24.3±6 respectively) with significant (P-value=0.04). Interestingly, Intra-operative blood loss in lateral approach is more than medial approach (175±25.3, 160.1±30 respectively) with significant (p-value=0.02). The interval to oral intake (3±0.3 days extended medial, 4.1±0.7 lateral, P=0.14).Conclusions: An extended medial approach for SFM during low anterior resection of rectal cancer appears to be an improvement over the previously used lateral approach because it may provide a shorter operation time and higher number of harvested lymph nodes with less intra-operative blood loss.

Published: March 2019

O objetivo deste artigo é caracterizar o Projeto Pedagógico do Curso de Licenciatura em Educação do Campo (PPC/LEdoC/UFPI) e suas interfaces com a prática educativa. Realizou-se pesquisa de abordagem qualitativa e de caráter descritivo, procedendo à observação de fatos e fenômenos exatamente como ocorrem em contextos reais. Utilizou-se análise documental do PPC e observação simples, como procedimentos de produção de dados. Os resultados apontam que existem avanços, desafios e possibilidades para essa formação. Os avanços referem-se ao delineamento, execução e contribuição para uma formação crítica e transformadora, bem como a ampliação do número de matrículas no Ensino Superior. Os desafios principais são as longas distâncias que separam a Universidade e as comunidades rurais em que os educandos residem, dificultando o acompanhamento e a orientação dos estudantes pelos professores e o fato de a maioria dos docentes não conhecerem a organização do trabalho pedagógico por meio da alternância e área do conhecimento, necessitando, portanto, de contínuos processos formativos e autoformativos, que favoreçam a compreensão e execução dessa proposta. No que se refere às possibilidades, a principal é a formação de novos perfis de professores, cuja dimensão política possibilite a construção de uma visão crítica sobre as contradições vividas na realidade e a capacidade de intervenção, a partir da relação teoria e prática.

Evolution of the account of Duke Godfrey’s deed of hewing the enemy through the middle with a single blow during the siege of Antioch by the First Crusade. A source study
Authors: Dźwigała Bartłomiej
Published: March 2019

The article contains research on the narratives describing the battle of the Bridge Gate (March 6, 1098), which took place during the siege of Antioch by the Crusaders. It focuses on the scene which is the climax of the above-mentioned tale, when the duke Godfrey of Bouillon hews the Turkish warrior through the middle with a single stroke of the sword in a duel on the bridge in front of the city. The study is divided into three parts. The first one includes views of historians regarding the accounts of hewing the foe through the middle by Godfrey as well as an analysis of the earliest stage of shaping the literary tradition of the studied scene, which in the opinion of the author of the article consists of descriptions created by Crusade participants: Raymond of Aguilers, Peter Tudebode and that included in the chronicle of Albert of Aachen. The second part focuses on the modifications and transformations of the earliest accounts introduced by chroniclers from Capetian France in the first two decades of the 12th century. The last part is devoted to an analysis of the later versions of the scene and their connection with earlier accounts. Research showed that the most popular and vivid version of the tale was created by Robert the Monk, yet there are clear connections with the earlier versions of the account even in the case of authors writing at the end of 12th century and later.
‘The most momentous epochs in Jewish life’. American Jewish Congress in Philadelphia (December 15–18, 1918)
Authors: Jeziorny Dariusz
Published: March 2019

The American Jewish Congress began its activities as an organization established to represent all Jews living in the United States during the Congress in Philadelphia. On December 15–18, 1918, a meeting of 400 delegates representing all Jewish political parties and social groups in the USA took place. It aroused great hopes because new opportunities were opening up for the Jews to resolve the Palestinian question, the main Zionist project, and to guarantee equal rights for Jewish minorities in East-Central Europe. The article answers questions about how the American Jewish Congress was convened. How did the main political groups of Jews in the USA respond to it? What was the subject of the debate? What decisions were made? And then how were they implemented and what was the future of the initiative launched in Philadelphia? Answers to these questions will allow us to draw a conclusion as to the importance of the December congress in the history of Jews in the USA and whether it fulfilled its tasks.

Tie-System Calibration for the Experimental Setup of Large Deployable Reflectors
Authors: Cammarata Alessandro , Sinatra Rosario , Rigato Riccardo , Maddio Pietro Davide
Published: March 2019

The tradeoff between the design phase and the experimental setup is crucial to satisfy the accuracy requirement of Large Deployable Reflectors. Manufacturing errors and tolerances change the RMS of the reflecting surface and require careful calibration of the tie rod system to be able to fit into the initial design specifications. To give a possible solution to this problem, here two calibration methods, respectively for rigid and flexible ring truss support, are described. Starting from the acquired experimental data on the net nodal coordinates, the initial problem of satisfying the static equilibrium at the measured configuration is described. Then, two constrained optimization problems, for rigid and flexible ring truss support, are defined to meet RMS accuracy of the reflecting surface modifying the tie lengths. Finally, a case study to demonstrate the validity of the proposed methods is presented.
Volatility Spillover from Global Container Freight Indices to Port Throughputs in Turkey
Authors: AÇIK Abdullah
Published: March 2019

The purpose of this
study is to determine the relationship between the container freight rates and
the volume of container handled at Turkish ports. To do this, causality in
variance analysis is used which enables to determine the volatility spillover
from global container freight indices, which are Shanghai Containerized Freight
Index (SCFI) and China Containerized Freight Index (CCFI), to container volume
handled in Turkish ports. The data set used in the study consists of 93
observations on a monthly basis covering the dates between November 2010 and
July 2018. According to the results obtained, a significant volatility
spillover has been only detected from the CCFI variable to the container
volume. In addition, it has been found that the container volume in Turkish
ports has reacted negatively to a positive shock in China container freight
index. It is hoped that these results will help the port operators in the
policy development stages by providing a leading indicator.

Acoustic Telemetry Network Provides Real-Time Downhole Data Transmission During Drilling, Cementing and Completion Installation for Use in Depleted Reservoirs and During Managed Pressure Operations
Authors: Hawthorn Andy , Groves Duncan
Published: March 2019

The last several years has seen an increasing trend toward more depleted reservoirs and more challenging wells with tighter mudweight windows. Managed Pressure Drilling has been employed in these challenging well conditions, however industry take up has been slow for a number of reasons including technical, economic and deployment related. Those wells that have utilized Managed Pressure Drilling have tended to focus on the drilling related aspects of well construction. However, other areas of well construction such as casing and liner running and cementing and completion installation are equally and in some cases even more technically challenging. One area that has potentially hindered the uptake of Managed Pressure Drilling is that in general, and in particular in the well construction operations outside of on bottom drilling there has been no access to real-time downhole data. In particular this is related to real-time pressure data. Whilst cementing, displacing or completing then multiple fluid types and densities may be circulating both inside and outside the drillpipe, leading to significant challenges in simulations and models derived from surface data.

To overcome this a new acoustic telemetry and measurement network is being deployed in depleted reservoir and managed pressure drilling operations to provide real-time downhole and along string measurements of pressures, temperatures and weights. Real-time data case histories will be shown from the Gulf of Mexico and the North Sea illustrating how this is being used to drive real-time decisions during drilling, cementing and completion installation operations in tight margin windows, depleted reservoir conditions and under managed pressure drilling operations.

MPD techniques have being applied to drill zones with major fluid losses or narrow operational window. Nevertheless, subsequent operations are not yet at the same stage of development: Wireline logging, running casing and cementing are still challenging and need further development when it comes to DP rigs. Therefore, after drilling a well with hydrostatically underbalanced fluid and surface backpressure, it is necessary to replace the drilling fluid in order to continue the operations. Although, in nearly all MPD wells it is possible to do this, the major challenges are zones with absent drilling window and severe losses where PMCD technique is required. In these cases, it is not possible to use overbalanced drilling fluid. This paper presents a solution for wireline logging while using MPD techniques on DP rigs with underbalanced drilling fluid. At first, it shows the planning phase and its discussion, then the execution phase with its difficulties.

This paper presents design, testing, installation, and lessons learned with the world's first completely integrated managed pressure drilling (MPD) control system on a deepwater drilling rig. While previous MPD installations have included driller-operated systems, they all include additional human machine interfaces (HMI) and standalone control network components with limited use of rig data and limited to no interfaces to other critical drilling machines on the drilling rig.

For the installation described in this paper, all MPD control functions were permanently installed on the main drilling control network of the drilling unit, providing direct access to high speed data from other drilling machines that influence the wellbore pressure. This includes the rig's mud pumps, top drive, and drawworks. Moreover, the MPD control system has the ability to actively control the drilling machines, thereby optimizing performance through coordinated control of mud pump, top drive, and MPD chokes during drilling and connections.

During the development phase, the specific drilling control system for the vessel was replicated in a hardware-in-the-loop environment, including all the main PLC software for the drilling machinery and supporting subsystems such as logging servers. This approach greatly reduces the risk of errors during installation, commissioning, and operation.

The most essential MPD parameters and control set-points are included in the standard drilling screen for immediate overview and monitoring, with the ultimate goal being a robust and advanced, but low OPEX MPD deployment, delivered by the drilling contractor.

In 2015, while coring in the carbonate reservoir in the second appraisal well on an oil and gas discovery in the Barents Sea (386 m water depth), the drill string fell 2 meters and a total mud loss was experienced leading to a well control incident. As a result, since 2016, the operator has introduced and used the Controlled Mud Level (CML) system. To date this system has been used on seven wells including two further appraisal wells on the same field and five exploration wells in the area.

In 2017 it was decided to drill a horizontal well in the same carbonate reservoir and to perform an extended production test in close proximity to the original loss well. Since it is not possible to predict where large voids (karsts) and natural fractures could be encountered, contingency to handle high losses, had to be implemented for the horizontal well. During the well planning, further risk reducing measures were implemented, including the use of wired drill pipe to improve the management of the wellbore pressure profile. This paper describes the planning processes leading up to the operation and the highlights of the operation itself together with the lessons learned. It elaborates on how wired pipe, used in combination with the CML system, added value to the operation. It shows how it was possible to drill the reservoir section with a low overbalance while managing severe losses associated with open karsts and natural fractures and still maintaining the fluid barrier. Despite the severe losses encountered it was possible to safely drill and complete the well without any well control event by use of the CML system.
Development of a Practical Tool to Generate Influx Management Envelopes IME for MPD Field Operations
Authors: Helmi Mohamed , Cadd Michael
Published: March 2019

To safely plan and execute MPD Influx Control operations, the limits of the primary barrier envelope must be communicated and understood. These safe operating limits have historically been represented with an MPD Operations Matrix. More recently, the development of the Influx Management Envelope (IME) has provided a means of communicating the primary barrier limits with improved accuracy and clarity. However, the generation of the IME currently requires performing a series of complex well control simulations with specialist engineering support. Because drilling operations are dynamic in nature, a practical method to generate the IME boundaries at the wellsite is required so that changes to mud weight, flowrate, surface and bottom hole circulating temperatures, trajectory, and bit depth can be accounted for, and the IME kept up to date.

This paper describes the development of a novel tool to quickly and automatically generate IMEs at the wellsite without the need for sophisticated modelling software and specialist personnel. The single bubble derivation that was originally presented by Culen et al was analysed further to obtain a more accurate and explicit relationship rather than an implicit one, which forms the basis for the calculations. The IME can be updated based on any well parameter changes, which allows field engineers to maintain an up to date and accurate IME throughout MPD operations.

Manage Pressure Drilling is not a new technology, but the transition from land operation to floaters is still recent. This created a situation where drilling contractors and operators are still learning what the true capabilities of the technology are.

MPD technology adoption on floaters can be divide it in 3 different phases: Use for Early Kick Detection and wellbore stability improvement;Introduction of Hydrostatically Underbalanced fluid;Influx circulation through the MPD system;

In the first phase most of the procedures and barrier concepts stay untouched.

After eliminating initial skepticism, second phase commences. Hydrostatic pressure exerted by the fluid is inferior to the formation pressure. Primary barrier concept alters. The technology can be applied to drill wells with narrow operational windows, unviable conventionally.

Finally, third phase starts with very limited volumes being allowed to be circulated through the MPD system. After first successful influx circulations through the MPD system, increased volumes may be encouraged to be circulated through the primary barrier.
Using Managed Pressure Drilling and Early Kick/Loss Detection System to Execute a Challenging Deepwater Completions Job in the Gulf of Mexico

Managed Pressure Drilling (MPD) technology was used to successfully drill challenging hole sections, and to run and cement casing strings for a deepwater campaign in the Gulf of Mexico. Because this technology offered the advantages of precisely manipulating the annular pressure using a statically underbalanced mud weight within a narrow pressure window, MPD was also employed along with real-time downhole measurements (from XACT), to run the lower completion assembly into the drilled production interval and perform downhole operations.

For this specific case, the prognosed pressure operating window was around 100 psi, however; the actual window was found to be 50 psi when losses were encountered while drilling the openhole section through the target reservoir. Consequently, the completions operations required the most accurate modeling and planning to keep losses at an acceptable rate while avoiding an influx or formation collapse. MPD was utilized to precisely manage downhole pressures while running the lower completions assembly, displacing the drilling mud with completions fluids in the openhole section, and monitoring losses during the breaker acid job.

A complex pump schedule was created by analyzing the pressure at several critical points in the open hole. Through back pressure management and high-resolution losses rate seen through the Coriolis flow meter, these losses were kept at a reasonable level to avoid breaching the pore pressure gradient and the wellbore stability limit. This paper describes the planning and execution processes that made this deepwater managed pressure completion job a success.
