Setting Training Standards For Emergency Response: A Case Study Of Training Rescue Teams In Remote Areas
Authors: Case G.. , Davis Gordon , Daher E.. 
Published: June 2015

Abstract
A safety company was tasked with training and certifying a rescue service for a major oil and gas facility in Southern Africa. In developed regions, the training criteria and requirements for emergency response workers are set by government legislation. Industry associations also play a lead role in setting training standards. The provision of a highly trained rescue team without the benefits of state-of-the-art equipment and facilities is a challenge in remote areas.
As a best practice, the safety company followed the National Fire Protection Association (NFPA) standards and training procedures employed in North America. Due to the remote location of the site, the confined space training had to be done using simulators and mock-up training towers. To ensure that safety standards were in place and not “watered down” for the field, rescue managers conducted a thorough review of industry best practices and brainstorming sessions with peers before and after trial runs.
The operator needed to see proof that the safety company and its local personnel were up to the task. The company had training facilities for other operations on the base. A well jacket simulator with a hatch in the landing deck area made a great location for the high angle practice and vertical confined space. Sea containers with plywood partitions and man ways cut out allowed for horizontal confined space practice. To support the project, the operator provided mockups of actual working structures and situations including a twenty-foot high representative section of a crude tower constructed from scaffold and plywood and wrapped in landscape fabric. A section of the deethanizer tower was also fabricated to ensure the rescue team could extract someone from what some were calling an impossible rescue situation. After a series of trial runs, the safety company successfully trained a team of local personnel with the same skill sets that would be expected in any part of the world. A demonstration of the final rescue procedure assured the operator that local personnel are now equipped to handle emergency rescue and are prepared to meet all situations at any time.
The lack of proper training facilities and legislation governing certification does not have to lead to rescue services that are not up to par with international standards. This paper discusses the standards an operator should expect from its emergency services regardless of location. With a strong commitment to safe work practices and a little creativity from the trainers, operators should not have to settle for anything but best-in-class emergency response utilizing local labor resources.
Drilling Wastewater Post-Treatment by Reverse Osmosis Method. Discussion and Practical Results.
Authors: Chávarro Roa M. R. 
Published: June 2015

AbstractDuring the last years, drilling operations have increased into areas where water resources have been affected by different natural phenomena and where strikes and social conflicts have been generated by drilling activities. In addition, current government protocols are more limiting about fresh water abstraction and their use, and wastewater disposal methods. For those reasons, environmental sustainability has become in one of the oil and gas industry's main concerns.For drilling operations a large volume of water is required, including domestic and industrial processes. Thus, taking into account several experiences in diverse Colombian oil drilling fields operated by Ecopetrol, show that the average of drilling water consumption per drilling rig is roughly 400 barrels of water per day and the wastewater volume to be disposed by different methods is coming from mud dewatering process followed by a physical and chemical treatment. That volume of wastewater contains dissolved salts such as chlorides and sulphates which make it impossible the re-use the water into the drilling mud process due to high content of salts that affects directly the polymers reactions of the drilling mud causing an inadequate fluid rheology.To tackle that situation, a wastewater management was designed to create a closed loop minimizing the environmental impact in terms of fresh water abstraction and wastewater discharge. Therefore, reverse osmosis process was implemented in those fields located in areas where water resources or disposal methods have been restricted by the environmental licences. As consequence of this wastewater technology as post-treatment step has permitted to re-use, in some cases more than 90% of the wastewater for preparing new drilling mud, fluids dilution and industrial uses. On the other hand, an important decrease of water abstraction was achieved as result of the reverse osmosis implementation.A discussion about reverse osmosis process as eco-friendly technology and cost-effective management of the drilling wastewater production has been provided, summarising some relevant results obtained in different oil drilling fields operated by Ecopetrol in Colombia. In addition, it is important to show how Ecopetrol is committed with environmental and sustainable development reducing the impact from the drilling operations.

Abstract
Process Safety… Beyond Personal Safety in Drilling
Various events in oil well drilling led to the development of control and prevention systems for low-probability, high-impact events that can affect lives, ecosystems or the integrity of equipment.
A low-impact loss of containment event on the surface during fracturing operations in the Colombian Piedemonte Llanero region highlights the need for a process safety management system that goes beyond a successful culture focused on personal safety. Operators in particular, supported by hydrocarbon service companies, adopted various approaches in the pursuit of process safety for the highest-impact risks in the value chain, within upstream, midstream and downstream activities. Process safety includes the service provided or scenarios of credible major risks such as control for wells, falling objects and spills.
In addition, companies providing services associated with exploration and production, such as BHI, focused their efforts on the mitigation of events or failures in tools, products or services that may contribute to loss of well control.
Ensuring suitable synergy, in terms of methods and controls, can be developed in projects such as those implemented in high-impact locations such as the Colombian Piedemonte Llanero, wherein the use of the service procurement method developed by Equion Energy, makes it possible to manage process safety through the models of both the operator and the service companies.
This paper presents the experience in harnessing this synergy, and emphasizing the methods adopted by Equion Energy and Baker Hughes. The paper highlights the creation of a process safety culture, which is reflected by the industry with personal safety through the utilization of advances in management systems.
Developing a culture of process safety is the starting point and culmination of strategies focused on identifying the greatest hazards, determining the reliability of barriers and preparing for emergency response and continuous learning, to consistently reduce hazards associated with the loss of hydrocarbon containment during the lifecycle of a well.
Water Management: What We Have Learned and What We Need to Consider for Developing a Shale Play in Argentina

Published: June 2015

Abstract
Hydraulic fracturing has been active in Argentina since the 1960s. The first jobs were performed using oil-based fluids. Throughout the years, new water-based fluids were introduced to replace alcohol-based fluids and foams based on reservoir requirements, economics, and safety and environmental issues. Currently, more than 95% of hydraulic fractures performed in the country are made using aqueous-based fluids.
Recently, exploration and development of resource shale plays, such as the Vaca Muerta, have begun. To achieve commercial production, this type of reservoir must be stimulated by hydraulic fracturing using large volumes of water. From 2009 to present, various exploration techniques have been performed in different shales, such as Los Molles, Vaca Muerta, Agrio (Neuquén Basin), Cacheuta (Cuyo Basin), and the D-129 (Golfo San Jorge Basin).
This paper discusses aspects of water logistics necessary during the well completion phase, fracture treatment designs applied in Vaca Muerta, and laboratory studies performed on flowback and produced waters to help evaluate the potential for water reuse.
The focus is on three different phases of water cycles for these projects. Water sources and stimulation: information for vertical and horizontal wells based on physical-chemical characteristics of various freshwater for stimulation, volume of water used, type of fracture treatment, and fracture fluid and additives used.Logistics: evolution of different water storage and transport options used for shale projects on single or multiple well pads.Reuse of flowback and produced water: laboratory tests on different flowback and produced water and/or blends (freshwater-flowback-water), treated and untreated including:–Physico-chemical characteristic of water (flowback and produced) from different wells.–Formation sensitivity tests with different water sources and usage possibilities.–Fracture fluids, conventional borate fluids, and a new low-residue CMHPG-metal formulated fluid using no traditional water treated and untreated with high total dissolved solids (TDS).
Cardio Renal Syndromes 2015: Is there a Silver Lining to the Dark Clouds?
Authors: Jamboti Jagadish 
Published: June 2015

Kidneys have a pivotal role in maintaining our homeostasis. Kidneys and heart work in tandem to maintain volume homeostasis. Heart failure impacts renal function in many ways including renal hypo perfusion but also due to increased venous pressure along with stimulation of various neuro-humoral responses. Renal failure induces cardiac damage and dysfunction by causing volume overload, inflammation and cardiomyocyte fibrosis. Concomitant comorbidities like Hypertension and Diabetes also play important role resulting in Cardiorenal Syndrome (CRS). Acute Dialysis Quality Initiative, 2007 recognized the bidirectional nature and different manifestations of CRS in acute and chronic settings.
Diuretics are the most common drugs to treat the most common symptoms of CRS i.e., peripheral edema and pulmonary congestion. Diuretics could nevertheless contribute to worsening renal function (WRF). Initially it was accepted that WRF during the course of treatment of acute decompensated heart failure (ADHF) uniformly resulted in worse prognosis. However, in view of a few recent studies, the significance of WRF early in response to treatment of ADHF is being debated. The optimal dose and method of delivery of diuretics is still undecided.
Isolated ultrafiltration does not improve renal function in patients with CRS despite the early promise. A large, multicentre trial ruled out any survival benefits with Recombinant Brain Natriuretic Peptide (Nesiritide). Despite good physiological basis and early promise with smaller studies, many drugs like Dobutamine, Rolofylline and Tolvaptan failed to show survival benefit in larger studies. However, two recent studies involving Relaxin and Neprilysin have shown good survival advantage. There had been little progress in treatment of CRS until studies involving Relaxin and Neprilysin inhibitor combination with ARB were published.
There may after all, be a glimmer of hope in the field of CRS bogged by multiple negative studies.
Lack of early inbreeding depression and distribution of selfing rates in the neotropical emergent tree Ceiba pentandra: Assessment from several reproductive events
Authors: Lobo Jorge A. , Jiménez Dennis , Solís‐Hernández Wendy , Fuchs Eric J. 
Published: June 2015

• Premise of the study: Selfing and mixed mating systems are prevalent in many flowering plants. Purging of genetic load can occur in these species, reducing negative effects of selfing. Long‐term studies of the temporal and spatial variation of selfing rates and inbreeding depression at the individual level are necessary to understand the forces that maintain selfing as a mating strategy in these species.• Methodology: We used microsatellites to estimate selfing rates in seeds and seedlings over 6 years in a population of Ceiba pentandra in southwestern Costa Rica. We studied the correlation of selfing with early seedling vigor variables to test for inbreeding depression.• Key results: Selfing rates varied widely among maternal trees. However, we found high consistency of selfing rates for individuals among years. Selfing rate did not influence early fitness traits, suggesting a lack of inbreeding depression at this stage. Maternal effects were a predominant source of variation for early vigor variables.• Conclusions: Variability in selfing rates among trees may be partly explained by genetic variation in a late‐acting self‐incompatibility system or low, early‐acting genetic load in some individuals. This population did not show evidence of early inbreeding depression in traits related to seed vigor probably from complete or partial purging as a result of repeated selfing of a fraction of the population or from strong maternal effects. Expression of genetic load at later developmental stages or in more stressful natural conditions may explain differences in inbreeding levels between seeds and adults.

• Premise of the study: Phylogenetic and morphological studies have helped clarify the systematics of large and complex groups such as the tribe Crotoneae (Euphorbiaceae). However, very little is known about the diversity, structure, and function of anatomical features in this tribe. Crotoneae comprises the species‐rich pantropical genus Croton and six small neotropical genera. Here we characterized the anatomy of leaf secretory structures in members of this tribe and explored their function and evolutionary significance.• Methods: Young and mature leaves of 26 species were studied using standard anatomical light microscopy techniques. Three sections of Croton and one representative of Brasiliocroton and Astraea were sampled.• Key results: We identified five types of secretory structures: laticifers, colleters, extrafloral nectaries, idioblasts, and secretory trichomes. Laticifers were present in all species studied except Croton alabamensis, which instead presented secretory parenchyma cells. Articulated laticifers are reported in Crotoneae for the first time. Colleters of the standard type were observed in the majority of the sampled taxa. Extrafloral nectaries were present in section Cleodora and in B. mamoninha, but absent in section Lamprocroton and Astraea lobata. Idioblasts were spread throughout the palisade and/or spongy parenchyma in most of the studied species. Secretory trichomes were restricted to Lamprocroton except for C. imbricatus.• Conclusions: This study revealed a high diversity of secretory structures, including novel ones, in one of the largest clades of Euphorbiaceae. Our results are promising for investigations on the anatomical and ecophysiological bases of species diversification within Euphorbiaceae.

Objective.To determine whether the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) is valid in identifying patients who had a clinically important overall improvement with no worsening in other descriptors/systems.Methods.Consecutive patients with systemic lupus erythematosus with active disease who attended the Lupus Clinic between 2000 and 2012 were studied. Based on the change in the total SLEDAI-2K scores on last visit, patients were grouped as improved, flared/worsened, and unchanged. Patients showing improvement were evaluated for the presence of new active descriptors at last visit compared with baseline visit.Results.Of the 158 patients studied, 109 patients had improved, 38 remained unchanged, and 11 flared/worsened at last visit. In the improved group, 11 patients had a new laboratory descriptor that was not present at baseline visit. In those 11 patients, this new laboratory descriptor was not clinically significant and did not require a change in disease management.Conclusion.The SLEDAI-2K identifies improvement in disease activity overall without concealing clinically important worsening.

Published: June 2015

Objective.Research on psoriatic arthritis mutilans (PAM), the most severe form of psoriatic arthritis, is impeded by the lack of an accepted classification criteria. We performed a systematic review of the literature to identify and synthesize clinical and radiographic features associated with the definition of PAM.Methods.A systematic literature search limited to human studies was conducted without language restriction. Abstracts were independently screened by 2 investigators and studies that reported information on patients with PAM were included. A standardized form was used to independently collect clinical and radiographic items defining PAM, patient’s demographics, disease characteristics, and outcomes.Results.There were 8570 citations searched to identify 112 articles for full review and 58 articles for data abstraction. We identified 8 definitions of PAM that were used in 283 subjects with a mean age ± SD at diagnosis of PsA of 33.9 ± 8.2 years. Disease manifestations (prevalence) included dactylitis (29–64%), enthesitis (29–32%), axial disease (14–27%), and nail lesions (47%). PAM definitions include 1 (n = 2 studies) or more (n = 14 studies) joints involving interphalangeal, metacarpophalangeal, or metatarsophalangeal joints. The most prevalent PAM clinical features were digital telescoping (34%), digital shortening (33%), and flail joints (22%). The most prevalent PAM radiographic items were bone resorption (41%), pencil-in-cup change (16%), total joint erosions (14%), ankylosis (21%), and subluxation (7%).Conclusion.We have identified 8 definitions of PAM, and synthesized the clinical and radiographic items that are important for the classification of PAM. We have established the groundwork for future development classification criteria for PAM.
L’élément ludique de la culture. À propos de Homo ludens de Johan Huizinga
Authors: Dewitte Jacques 
Published: June 2015

Si les animaux jouent déjà, ne peut-on faire l’hypothèse que la culture humaine suppose l’existence d’un champ premier, irréductible à la simple fonctionnalité et à l’utilité, auquel participent tout à la fois les animaux et les hommes ? Cette hypothèse d’un « champ ludique », qui précède la culture et dont elle procède, conduit alors à reconnaître au jeu une dimension transcendante qui englobe et enveloppe toutes les activités humaines. À l’instar du don, le jeu manifeste, par son archaïsme même, les conditions anthropologiques sans lesquelles la vie sociale serait impossible. Pour autant, le jeu n’est-il pas voué à ne devenir qu’une simple survivance dans nos sociétés contemporaines tant celles-ci semblent devenir comme étrangères à cette alliance de la règle et de la liberté, constitutive de l’esprit du jeu ?
Jeux d’écriture : la tragédie de l’ethnographe
Authors: Illouz Charles 
Published: June 2015

Dans Homo ludens , Huizinga étudie le rapport existant entre poésie et situations ludiques agonales. Sous la variété des genres qu’elle connut dans l’histoire, la poésie relève du jeu et du don dès lors que chaque nouvelle production met ceux qui s’y risquent ensuite en dette de nouvelles formes à créer. Toute société fait circuler parmi ses membres une forme de savoir qui repose sur l’expertise de ceux qui suscitent l’enthousiasme ou la critique cinglante. Anticipant la « riposte » d’un auditeur ou d’un lecteur faisant autorité, tout auteur évolue ainsi, selon la remarque de Clifford Geertz visant l’ethnographe, dans un « théâtre de langage ». S’appuyant sur la définition de la « fonction-auteur » de Foucault, cet article définit une fonction-acteur pour décrire le jeu agonistique inhérent à l’écriture anthropologique.
