and their relationship to nitric oxide production by endothelium.

Design and methods.The study involved 141 patients with hypertension, including isolated hypertension, and associated with coronary heart disease and type 2 diabetes mellitus. Methods of investigation included the evaluation of clinical and conventional instrumentation and laboratory parameters with the additional study of heart rate variability. To assess endothelial function we determined the level of the final stable metabolites of nitric oxide: nitrite and nitrate anions (NO2 - and NO3 -) in blood plasma.

 Results and conclusions.According to the analysis of heart rate variability we found apparent disturbances of heart rhythm regulation in hypertensive patients: decreased overall heart rate variability, decreased amplitude of parasympathetic, sympathetic and humoral waves, reduced proportion of sympathetic, parasympathetic waves and increase of humoral waves. Co-existing diabetes mellitus led to more apparent disturbances of autonomic regulation of heart rhythm. High heart rate and low heart rate variability in hypertensive patients are associated with an increase of the final metabolites of nitric oxide in the blood plasma.

Published: December 2018

Objective. To study and compare indicators of systemic inlammation and red blood cells glutathione redox potential by chronic oxidative stress (OS) in patients with coronary heart disease (CHD), type 2 diabetes mellitus (T2DM) and the combination of both diseases.

Design and methods. The study included 35 patients with CHD and newly diagnosed T2DM, 109 patients with CHD, 19 patients with T2DM, and 89 healthy individuals. Systemic inlammation indicators were measured including concentration of interleukin (IL) 6 and 8, myeloperoxidase (MPO) and OS in plasma, oxidized (GSSG) and reduced (GSH) glutathione, as well as their ratio and redox potential (E), the activity of glutathione reductase (GR) and glutathione peroxidase (GP) in red blood cells.

Results. Signiicant growth of systemic inlammation (IL-6, IL-8, MPO) indicators on the weakening antioxidant defense enzyme has been registered in patients with a combination of CHD and T2DM, a 3,4-fold reduction of GSH level, 5,8-fold of 2GSH/GSSH in red blood cells and E values towards the oxidized state at 36,3 mV were noted. These changes were less pronounced in CHD group and were absent in T2DM group. All subjects showed a decreased activity of GP and increased level of glycosylated hemoglobin. The correlation of E and activity GR have been found in patients with carbohydrate metabolism disorder. High positive relationship between IL concentration and red blood cells GR, E indicators has been identiied in patients with CHD and T2DM. There is a need to control and correct cellular redox potential in patients with CHD and T2DM.

Conclusion. The combination of CHD and T2DM contributes to the decrease of red blood cells redox status glutathione secondary to the increased systemic inlammatory response and chronic OS indicators.

Objective. To study interconnection between hyperleptinemia, the quality of life (QOL) and the severity of metabolic disorders in patients with essential hypertension with metabolic syndrome (MS).

 Design and methods.We have examined 46 patients with essential hypertension (blood pressure < 180/110 mm Hg), accompanied by MS. Along with complete clinical, laboratory and instrumental examination, customary in a specialized cardiologic clinic, the QOL research was carried out using MOS SF-36questionnaire. Besides, the concentration of leptin in blood serum was determined.

Results and conclusions. Patients with essential hypertension with hyperleptinemia show higher intensity of clinical and laboratory markers of MS, higher activity of the systemic inlammatory response and increased QOL. A statistically signiicant inverse correlation between serum leptin level and QOL scales (SF-36) was detected.
HYPERHOMOCYSTEINEMIA AS A FACTOR OF FIBRINOLYSIS DISTURBANCES IN PATIENTS WITH ACTIVATED INTRAVASCULAR COAGULATION
Authors: Subbotina T. F. , Zhloba A. F.
Published: December 2018

Background. High blood concentration of D-dimer is a reliable marker of activation of intravascular coagulation, but does not provide unambiguous information about the functional potential of the ibrinolytic system.

Objective. To determine the contribution of hyperhomocysteinemia (HHcy) in ibrinolysis disturbances in patients with activated intravascular coagulation.

 Design and methods. Plasma samples of 141 patients with activated intravascular coagulation of various etiologies [82 women (58,2 %) and 59 men (41,8 %), mean age 53,2 ± 7,8 years] with the level of D-dimer > 500 ng/ml were studied. The level of total Hcy (tHcy) was determined by high-performance liquid chromatography. In 57 samples ibrinolytic capacity was investigated by turbidimetric global coagulation and ibrinolysis test using as inducers thrombin and tissue plasminogen activator, respectively. 20 samples of donors matched for age and sex served as a comparison group.

 Results. In 52 patients (36,9 % of the total sample) tHcy level was greater than 12 µM, thus a modest HHcy was observed. In 29 patients (50,9 % of the patients tested for ibrinolysis capacity) the activation of intravascular coagulation was combined with hypoibrinolysis, and the frequency of HHcy in this group reached 58,6 %. A strong correlation between the time of ibrinolysis and tHcy concentration was found (Rs = 0,564, p = 0,0001).

Conclusion. Thus, it appears that moderate HHcy is not only one of the risk factors for the activation of intravascular coagulation, but also causes inhibition of ibrinolysis in this pathology.

Published: December 2018

Objective. To estimate clinical status, quality of life (QOL), physical activity, structural and functional pe-  structural and functional penal peculiarities of the heart in patients with chronic heart failure with preserved ejection fraction (CHF-PEF).

Design and methods. Seventy-two patients with CHF-PEF (age 47–77 years) were examined. Clinical status, QOL by Minnesota questionnaire, 6-minute walk test, heart ultrasound, serum N-terminal brain natriuretic propeptide level were assessed in all patients.

Results. Main complaint was dyspnea at physical activity in patients with CHF-PEF (95,8 %). Structural and functional myocardium changes were more expressed in patients with higher functional class. General total score by Minnesota questionnaire was 21,5 [14,5; 40,0] in men and 48,5 [36,0; 59,0] in women. Tolerance to physical activity influenced QOL.

Conclusions. All patients had echocardiographic signs of left ventricular diastolic dysfunction. The higher functional class of heart failure was associated with the more pronounced myocardial hypertrophy, decreased QOL and physical activity. QOL was higher in men, than in women. Diabetes mellitus, ischemic heart disease were associated with the clinical progression of CHF.
Posttraumatic Growth as a Mediator of Self-Blame and Happiness in the Context of Interpersonal Violence
Authors: Moschella Elizabeth A. , Turner Sidney , Banyard Victoria L.
Published: December 2018

Sexual assault (SA) and intimate partner violence (IPV) occur at alarming rates in the United States. Prior research indicates that victims of traumatic events frequently experience both positive and negative changes as part of their recovery process. The present study aimed to further existing research by examining the relationship between self-blame, posttraumatic growth (PTG), and happiness when controlling for posttraumatic stress and time since victimization. The current study analyzed 357 women who had experienced at least one incident of SA or IPV. We found that PTG partially mediated the relationship between self-blame and happiness, suggesting that PTG only somewhat explains the impact of self-blame on victim happiness. Implications of these findings and directions for future research are discussed.
William Frantz Public School: One School, One Century, Many Stories
Authors: Schaffer Connie Lynn , Brown Corine Meredith , White Meg , Viator Martha Graham
Published: December 2018

William Frantz Public School (WFPS) in New Orleans, Louisiana, played a significant role in the story of desegregation in public K-12 education in the United States. This story began in 1960 when first-grader, Ruby Bridges, surrounded by federal marshals, climbed the steps to enroll as the school’s first Black student. Yet many subsequent stories unfolded within WFPS and offer an opportunity to open the discourse regarding systemic questions facing present-day United States public education - racial integration, accountability, and increasing support for charter schools. In this article, these stories are told first in the context of WFPS and then are connected to parallels found in other schools in New Orleans as well as other urban areas in the United States.
Educational Administrators’ Perspectives of Democracy and Citizenship Education: Interviews with Educational Leaders.
Authors: Long Jordan
Published: December 2018

Little is known about public school educational administrators’ perspectives of democracy and citizenship education and how those perspectives shape the learning that occurs in the schools they lead. This paper presents findings of a qualitative study that used semi-structured interviews of public school educational administrators’ perspectives of democracy and citizenship education in the province of Alberta, Canada. Four participants’ detailed responses were analyzed using an interpretive phenomenological methodology and coded into four themes. While all four participants felt that democratic and citizenship education were important, their conceptualizations varied widely and only one participant was found to lead in a way that encouraged democratically desirable education. Findings suggest that some educational administrators do not necessarily understand their role or responsibility in the education of democracy and citizenship within the schools they lead. Moreover, this study suggests that factors that hinder democratic and citizenship education are: school administrators’ preference to remain obedient to a top-down approach of school management; resource taxing administrative obligations and; a misunderstanding of ‘thick’ democracy. Factors that were found to facilitate democratic and citizenship education include: physical school and learning program design and; democratic school leadership.

J. S. Bach em português: a escolha textual de Furio Franceschini e Martin Braunwieser para a Johannespassion BWV 245
Authors: Gabriel Ana Paula Dos Anjos
Published: December 2018

A realização de performances em português de música coral estrangeira era prática bem estabelecida na cidade de São Paulo do início do século XX à década de 1960. Entretanto, as traduções caíram em progressivo desuso ainda na segunda metade do século XX, constituindo atualmente um repertório pouco discutido pelos estudos de performance e práticas interpretativas no Brasil. Nesse contexto, este artigo faz uma discussão crítica a respeito da presença de traduções para o português de obras corais nas práticas musicais brasileiras do século XX, a partir de performances em português da Johannespassion BWV 245, de Johann Sebastian Bach, feitas por Furio Franceschini e Martin Braunwieser em São Paulo entre as décadas de 1940 e 1960. Referenciada na história da performance musical enquanto campo, nossa discussão é fundamentada em um conjunto de fontes documentais relacionadas aos concertos e em bibliografia composta por Mahraun (2016), Stauffer (1997), Goehr (1992) e Doyle (1980). Tanto a investigação bibliográfica quanto a investigação documental mostram que o uso de traduções foi uma escolha interpretativa diretamente relacionada à concepção de obra dos próprios maestros, como também a tradições de performance desse repertório provenientes da Europa e das conjunturas culturais e políticas de âmbito local. Em última análise, este artigo evidencia a presença desse repertório em São Paulo, sua importância histórica, seu valor artístico e suas aplicações práticas, a despeito de um contexto de crescente autoridade da obra musical sobre as práticas musicais dos séculos XX e XXI.

Communities That Care (CTC) es un sistema preventivo que busca disminuir comportamientos problemáticos en adolescentes. En Colombia, este sistema ha sido adaptado bajo el nombre de Comunidades Que se Cuidan (CQC). Este estudio validó las asociaciones entre los factores de riesgo y protección (FRP) para el uso de sustancias psicoactivas (SPA) medidos por CQC y las prevalencias de consumo de estas en adolescentes colombianos. Entre 2012 y 2016, se aplicó una encuesta a gran escala en jóvenes de 10 a 19 años (N = 50,946) pertenecientes a 23 comunidades de Colombia. Se analizó de forma transversal la asociación entre los FRP con el consumo de alcohol, cigarrillo, marihuana y otras drogas ilegales en los últimos 30 días, año y alguna vez en la vida. Se realizaron regresiones logísticas, ajustando por edad, sexo y sus interacciones con cada FRP. Todas las asociaciones de los 14 FRP evaluados fueron significativas (p < .001). De los efectos observados, 3,0% se consideraron efectos muy pequeños (0,70 ≤ OR ≤ 1,43), 51,7% pequeños (0,70 ≥ OR ≥ 1,43), 42,6% medianos (0,40 ≥ OR ≥ 2,48) y 7,1% grandes (0,23 ≥ OR ≥ 4,27). Se encontraron asociaciones significativas para edad, sexo y sus interacciones con los FRP para la mayoría de FRP. Los hallazgos demuestran la validez de los FRP estudiados para la planificación, el desarrollo y la evaluación futura de sistemas preventivos comunitarios como CQC, los cuales se basan en datos epidemiológicos para la toma de decisiones locales.

This study evaluated the patterns of substance use in a large sample of male-to-female (MtoF) and female-to-male (FtoM) transsexuals. A total of 251 transsexual subjects (163 MtoF and 88 FtoM), attended in the Catalonia Gender Unit, completed self-administrated questionnaires on consumption of alcohol, tobacco, cannabis, cocaine, opioids, and designer drugs. Results were compared with the general population in Catalonia using data from the National Health Service (EDADES 2013 study). Current consumption of alcohol (70.1%), tobacco (46.2%), and cannabis (16.3%) among transsexuals was similar when compared with men (72.1%, 42.1%, 12.8%) and increased when compared with women (57.6%, 35.2%, 5%); the consumption between MtoF and FtoM subgroups was similar.  The use of cocaine was almost ten times more prevalent in the MtoF subgroup than in the FtoM subgroup (1.1%), and in general population (less than 1%).  Only a few reported uses of opioids and designer drugs. In conclusion, the substance use among transsexuals, except for the use of cocaine, was similar between MtoF and FtoM subgroups, and resembled the consumption prevalence among men in the general population. The proportion of cocaine consumers in the MtoF subgroup was up to ten times higher than in other subgroups.

Religious court as forefront in economic sharia dispute resolution in litigation has not ideal place to perform their duty since there are still regulation conflicts such as implementation of encumbrance right execution which still becomes a domain in district court. As explained, this article discusses phi-losophical foundation of Religious Court competence to resolve economic sharia issues. In regard to this, conceptual approach, law approach and historical approach are respectively used. Based on the analysis, basic competence of religious court is Islamic personality principle which carries the use of Islamic law elements (sharia principle) in its legal relationship. From the analysis the implication is drawn that as long as a dispute belongs to economic sharia, then it is Religious Court which is com-petent to handle including court decision.Keywords: law enforcement, economic sharia dispute, absolute competence, court decision implementation
CONFISCATION ON STATE-OWNED ENTERPRISES (BUMN) ASSETS IN THE PERSPECTIVE OF TAXATION LAW
Authors: Muttaqin Zainal
Published: December 2018

Regime of the State Finance Law as stipulated in Law Number 17 Year 2003 and Law Number 1 Year 2004 classify separated state finances as State-owned enterprises (BUMN) capital into the definition of state finances of which assets are free from confiscation. The problem is in terms that BUMN as taxpayers do not pay the tax debt, thus is it possible for BUMN to be enforced by law in the form of confiscation of its wealth? This paper aims to analyze the above issues based on applicable legal doctrine. From a legal perspective, State-owned enterprises is a separate legal entity from the owner of capital (state). Thus, the capital sourced from the state in the State-owned enterprises is not the property of the state anymore yet a wealth of state enterprises as legal entities as well as taxpayers. As a result, Law Number 17 Year 2003 which explained that state assets separated in BUMN including state assets is inconsistent with applicable legal theory. Accordingly, Article 50 paragraph (1) of Law Number 1 Year 2004 should have not been applied to State-owned enterprises.Keywords: BUMN, Confiscation, Legal Entity, State Finance, Tax.

Modeling and Mechanical Design of an Active-Caster Omnidirectional Mechanism with a Ball Transmission
Authors: Kato Kosuke ,   Tokyo University of Agriculture and Technology 2-24-16 Naka-cho, Koganei-shi, Tokyo 184-8588, Japan, Wada Masayoshi
Published: December 2018

This paper presents kinematic and static analyses of an active-caster robotic drive with a single-layer ball transmission (ACROBAT-S). On the basis of the analyses, a single-wheel prototype is designed, and fundamental experiments using the prototype are conducted. The proposed ACROBAT-S includes a ball transmission that transmits power to a wheel axis and steering axis of an active-caster wheel in an appropriate ratio to produce so-called “caster motion.” The power distribution is realized mechanically rather than by complicated computer control algorithms. Therefore, the angle sensor for detecting the wheel orientation, and the control calculations for coordinated control of the wheel and steering motors of a conventional system are eliminated. Thus, the proposed mechanical design, which transfers a part of the control function to the mechanism, contributes to simplifying the overall control system. The results of the analyses and experiments with a prototype confirm that the proposed active-caster mechanism, ACROBAT-S, can realize the expected omnidirectional motion with simple motor control, such as Point-To-Point control.

Authors: Covert Hannah , Sherman Mya , Miner Kathleen , Lichtveld Maureen
Published: December 2018

Objectives. To establish a validated, standardized set of core competencies for community health workers (CHWs) and a linked workforce framework.

Methods. We conducted a review of the literature on CHW competency development (August 2015), completed a structured analysis of literature sources to develop a workforce framework, convened an expert panel to review the framework and write measurable competencies, and validated the competencies (August 2017) by using a 5-point Likert scale survey with 58 participants in person in Biloxi, Mississippi, and electronically across the United States.

Results. The workforce framework delineates 3 categories of CHWs based upon training, workplace, and scope of practice. Each of the 27 competencies was validated with a mean of less than 3 (range = 1.12–2.27) and a simple majority of participants rated all competencies as “extremely important” or “very important.”

Conclusions. Writing measurable competencies and linking the competencies to a workforce framework are significant advances for CHW workforce development.

Public Health Implications. The standardized core competencies and workforce framework are important for addressing health disparities and maximizing CHW effectiveness.

Published: December 2018

In response to increasing violent attacks, the Stop the Bleed campaign recommends that everyone have access to both personal and public bleeding-control kits. There are currently no guidelines about how many bleeding victims public sites should be equipped to treat during a mass casualty incident.

We conducted a retrospective review of intentional mass casualty incidents, including shootings, stabbings, vehicle attacks, and bombings, to determine the typical number of people who might benefit from immediate hemorrhage control by a bystander before professional medical help arrives.

On the basis of our analysis, we recommend that planners at public venues consider equipping their sites with supplies to treat a minimum of 20 bleeding victims during an intentional mass casualty incident.

Objectives. To examine the perceived benefits of and barriers to law enforcement agencies providing increased access to voluntary and temporary firearm storage.

Methods. We surveyed 448 police chiefs and sheriffs in 8 US Mountain West states about firearm storage practices, benefits of and barriers to storage, and related attitudes and beliefs. Data collection occurred during the spring and summer of 2016.

Results. Nearly three quarters of agencies reported that they are already providing storage and perceive relatively few barriers in doing so. Agency characteristics were not associated with current provision of firearm storage. Among the barriers identified included state laws, limited space, training needs, and community perceptions. Benefits of storage included being perceived positively by the community and supporting health care workers.

Conclusions. Engaging with law enforcement agencies in suicide prevention efforts and addressing their perceived barriers to providing temporary firearm storage have promise as part of a comprehensive suicide prevention approach.
How Close is too Close? Well Spacing Decisions Come With Risks

There is no formula for properly spacing wells in unconventional plays. When a reservoir consultant recently described conversations with clients about how many wells they could drill per acre, it sounded like a doctor advising a patient considering back surgery.

“I am not trying to tell you what your spacing should be,” said Miles Palke, management senior vice president for Ryder Scott, adding that the modeling and production history matching his company offers is “a process to help you inform your decision.”

The cautious approach was understandable in his talk at the recent SPE Hydrocarbon Economics and Evaluation Symposium. Well-spacing decisions are increasingly tricky because of the potential downsides, from damaging hits to older parent wells to production from new child wells falling short of the old wells.

A recent technical paper authored by Schlumberger (SPE 191799), based on data from the Wolfcamp shale play in the Permian’s Delaware Basin, found that when a new well is drilled within 1,000 ft of an older well, the older parent well outperformed the child well 66% of the time. When the results were adjusted for the bigger, more expensive completions now common, 79% of the older wells performed better.

It is getting harder to avoid the issue of well spacing. In its recent earnings call with investment analysts, Schlumberger said that 70% of the wells drilled in the Eagle Ford are infill wells, as are 50% of those wells drilled in the Permian.

While there is a lot of agonizing about fracs hits when wells are closely spaced, wider spacing also has its risks. Schlumberger predicted that even when the wells are 2,000–2,500 ft apart, the parent wells perform better 61% of the time when the production was adjusted for the larger volumes of proppant per foot now commonly used. As wells get farther apart, there is a growing chance that productive rock in between will never be stimulated.

Well interactions are a constant reminder that fracturing does not create networks of producing fractures shaped like shoe boxes that can be lined up neatly on a shelf. Fracturing the maximum volume of a reservoir requires dealing with the contact that comes when wells with irregularly shaped fracture networks are located side by side.

“People talk about well interference and bring it up as if it is a bad thing,” said Erdal Ozkan, SPE’s reservoir technical director. The petroleum engineering professor at Colorado School of Mines added that overlapping production “has always existed between two wells in the same field. There will be interference. If you reduce the drainable area, you reduce productivity of each well.”
Fewer Grads + More Jobs: A Winning Formula for Job Hunters
Authors: Rassenfoss Stephen

The 2019 graduating class of petroleum engineers will mark the last gasp of a boom before a steep drop in the size of future graduating classes coming out of US universities.

After a class of nearly 2,000 petroleum engineering graduates next spring, the graduation rate over the next 3 years will fall to less than 1,000 per year, according to an annual survey of US petroleum engineering programs by Lloyd Heinze, a professor at Texas Tech University. The survey includes primarily US universities. The numbers are a direct reflection of the sharp downturn in oil prices that began in 2014 and caused large downsizing among oil and gas operators and service companies.

For young engineers looking for jobs after college, it represents a welcome change from the rocky job market faced by graduates after the industry switched into job-cutting mode. For employers used to having their pick of the top students since the bust began in 2015, it could mean being one of several bidders for a shrinking pool of graduates.

Professors on campuses are seeing signs of improvement, but they caution that the evidence is more anecdotal than numerical.

“A good number of seniors have jobs and a lot do not. One thing is that it is a big senior class,” said Karsten Thompson, department chair for the petroleum engineering program at Louisiana State University (LSU). It is too early for hard numbers but “there are more companies on campus with more students having internships and job offers.”

“Internships went quite well this year. It looks like the recovery is under way. Students are much more comfortable,” said Erdal Ozkan, a professor at Colorado School of Mines.

The job market is much improved, said John Lee, a professor at Texas A&M who also sees improved internship opportunities.

Graduating Boomers

The class of 2019 is made up of the last big crop of freshman enrolled back in the fall of 2014 when the bust killed the assumption that $100/bbl oil was a given. The nearly 2,000 seniors in the 2018–2019 class is considerably smaller than the past two, which exceeded 3,200, but it is double the size of three classes that follow.

Texas Tech has 77 seniors now, compared with a peak total of 227 in 2014, and only 43 juniors following them. The junior class is 80% lower than the 2015 peak. That drop is an indication of Texas Tech’s decision not to limit petroleum engineering enrollment during the boom—only a few schools including Texas A&M and the University of Texas capped enrollment—and the quick reactions of a “population of students and parents who were faster to realize the downturn” because so many live in West Texas where the industry is all around them.

Between the boom in the early 1980s—where schools provided a generation’s worth of exploration and production professionals—and the recent boom that produced many more grads, was a long, deep slump.
Technology Focus: Mature Fields and Well Revitalization (January 2019)

Technology Focus

Mature brownfields contribute significantly to global oil production. A study of the papers presented during the past year at various SPE conferences reveals a continuation of the trend to put in massive effort to minimize decline from mature brownfields. This has been attempted through several means, such as improving well integrity and judicious well interventions to restart production from idle wells. One paper discusses a conceptual platform where all stakeholders (operator and service providers) can share and formulate a win/win strategy wherein operational efficiency and success rate of an activity are the main drives.

As an offshoot of such well-intervention activities, low-resistivity pay zones, either shallower or deeper with respect to the main pay and hitherto considered unattractive, have been identified and contribute significantly in sustaining production decline. There is an all-around emphasis on characterizing highly compartmentalized and difficult reservoirs that have thin reservoir sands defying well-to-well correlations because of a lack of marker shales. In some cases, the presence of conductive minerals such as pyrites or siderites further masks the presence of hydrocarbons in conventional log analysis.

In addition to efforts on improved reservoir characterization, optimizing ongoing waterfloods is an area where focused efforts are yielding rich dividends. These involve locating the bypassed oil and addressing unswept areas through reservoir surveillance and modeling. Some operators also have focused on innovative enhanced-oil-recovery techniques in mature brownfields to enhance production.

Managed-Pressure-Drilling Equipment Augments Deepwater Well Control
Authors: Carpenter Chris
Published: December 2018

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 186331, “Augmenting Deepwater Well Control With Managed-Pressure-Drilling Equipment,” by Austin Johnson, SPE, Brian Piccolo, Henry Pinkstone, SPE, Bo Anderson, and Justin Fraczek, SPE, AFGlobal, prepared for the 2017 SPE/IATMI Asia Pacific Oil and Gas Conference and Exhibition, Bali, Indonesia, 17–19 October. The paper has not been peer reviewed.

This paper describes how a technique known as applied-surface-backpressure managed-pressure drilling (ASBP-MPD) can alleviate the limitations of conventional deepwater well control. The paper discusses equipment design and operating philosophy, outlining actions that can be taken to respond to an influx while remaining within the primary well barrier.

Conventional Well Control: Background and Limitations

Industry personnel are trained to follow conventional well-control-response steps when securing a well and closing a subsea blowout preventer (SSBOP) once an influx is detected. The steps are logical from the perspective of adhering to the operating requirements of existing well-control equipment. While variations in procedures exist between companies, the logic behind these steps remains consistent across the industry. The conventional steps are as follows:

Stop rotating; pick up off bottom and space out

Stop the mud pumps

Conduct a static flow check

Close the SSBOP

Conventional well-control response is limited by the design and operating philosophy of conventional well-control technology. The challenges associated with these constraints include a significant drop in bottomhole pressure (BHP), increased influx volume before the well is finally secured, and the amount of time needed to detect an influx. The initial confirmation of an influx can take a substantial period of time because of a variety of factors that can influence the return flow rate and mud-pit volumes.

On a deepwater rig, the interpretation of pit-volume and flow-rate changes can be subjective. To complicate matters further, conventional drilling rigs often are equipped only with inaccurate paddle flowmeters on the main flowline to measure flow out of the well; these do not offer a precise flow measurement.

The conventional well-control-response procedure does not seem adequate for the deepwater drilling environment when evaluated in terms of influx detection and response time, total influx volume, and reservoir drawdown. Furthermore, after the SSBOP is closed, the conventional well-control response is subject to significant residual risks in the form of stuck pipe, lost circulation from chokeline friction, and the exceeding of kick tolerance. Finally, closing the SSBOP does not address an influx that has been circulated into the riser undetected.
