Between foreign and self: concepts of Hispanic American literature/Entre lo ajeno y lo propio: concepciones de la literatura hispanoamericana
Authors: Freja de la Hoz Adrián Farid 
Published: June 2015

El presente artículo de reflexión, resultado de la primera parte de la investigación sobre literatura tradicional palenquera y literaturas nativas en Colombia y Latinoamérica, titulado “La literatura oral de San Basilio de Palenque: poética de la literatura oral, popular y tradicional palenquera”, presenta un breve estado del arte sobre las distintas concepciones de la literatura hispanoamericana y latinoamericana por parte de importantes críticos y teóricos de la literatura en el siglo XX. El objetivo principal es develar los contrasentidos y paradojas que se tejieron alrededor del anhelo de una literatura “propia” de nuestro continente. El análisis es de tipo cualitativo interpretativo y como resultado se expone la manera en que algunos autores (Ángel Rama, Roberto Fernández Retamar y Pedro Henríquez Ureña) presentaron propuestas que van en contra de todas aquellas manifestaciones de los pueblos y culturas nativas del continente. Asimismo, se muestra la manera en que estos grandes pensadores latinoamericanos construyeron un imaginario de literatura hispanoamericana a partir de formas y concepciones artísticas propias de la tradición literaria de Europa.

Time-Dependent Initiation of Multiple Hydraulic Fractures in a Formation With Varying Stresses and Strength
Authors: Bunger Andrew P. , Lu Guanyi 
Published: June 2015

Summary
The premise of classical hydraulic-fracture-breakdown models is that hydraulic-fracture growth can only start when the wellbore pressure reaches a critical value that is sufficient to overcome the tensile strength of the rock. However, rocks are well-known to exhibit static fatigue; that is, delayed failure at stresses less than the tensile strength. In this paper, we explore the consequences of delayed failure on axially oriented initiation of multiple hydraulic fractures. Specifically, given a certain breakdown pressure, we investigate the conditions under which subsequent hydraulic fracture(s) can begin within the time frame of a stimulation treatment in regions of higher stress and/or strength because of delayed-failure mechanisms. The results show that wells completed in shallower formations are more sensitive to variations in strength, whereas wells completed in deeper formations are more sensitive to variations in stress. Furthermore, cases in which all hydraulic fractures break down according to the same pressurization regime—that is, all are “fast” (nonfluid-penetrating) pressurization or else all are “slow” (uniformly pressurized fluid-penetrating) pressurization cases—are highly sensitive to small stress/strength variability. On the other hand, if the first hydraulic-fracture initiation is in the “fast”-pressurization regime and subsequent fracture(s) are in the “slow”-pressurization regime, then the system is robust to a much-higher degree of variability in stress/strength. Practically, this work implies that methods aimed at moderately reducing the variability in stress/strength among the possible initiation points (i.e., perforation clusters) within a particular stage can have a strong effect on whether multiple hydraulic fractures will begin. In addition, this analysis implies that pumping strategies that encourage “fast,” nonpenetrative breakdown of the first initiation point followed by the opportunity for fluid-penetrating, “slow” breakdown of subsequent initiation points could be effective at encouraging multiple-hydraulic-fracture initiation.
Management in Ergonomics. A Tool to Enhance Results in Engineering Projects. Industry Case: Petrochemical in Colombia
Authors: Gil J. L. , Córdoba J. E. , Quintana L. A. , Nisperuza O. Bernal 
Published: June 2015

Abstract
Develop and manage a project seeking an optimum control of resources to achieve a series of objectives is a multidisciplinary task. Engineering seeks to align said management to a global trend to ensure that the specific capacities, limitations, demands and requirements of human beings have been taken into account from the initial concepts of design through ergonomics. This discipline, used as a managing tool and commonly known as Human Factors Engineering (HFE), allows an early approach that systematically outlines the problem to solve, focusing all efforts to the control of the source and not on future corrective solutions. Several industrial sectors have estimated the costs associated to ergonomic shortcomings in social terms (health of employees, occupational diseases) economic terms (low productivity, corporate restructuring, design and construction of facilities), and in the worst case scenario loss of life, permanent disability, days of healthy life lost and significant material damage in facilities. The following article presents the case of how successful the application of a system of ergonomics management was for the Colombian oil company, Ecopetrol SA, emphasizing on the development of this system in early project management. Presented below are the most important findings related to revision of projects of different nature and type of business, including transportation, production and refining for industrial and non-industrial facilities. The results have been presented as opportunities for improvement that allow corroboration and may even be subject to impact measurement as the projects progress. The steps presented in the following paper may be applied in engineering project in general.
Dispersion of Relief and Leaked Hazardous Gases on Offshore Facilities

Published: June 2015

Abstract
Hazardous gases, such as H2S and CO2, present high risks for health, safety, and environment on and near offshore facilities. In recent years, it has become more important to evaluate the pollution and process safety for dispersion of the leaked and relieved hazardous gases during an offshore operation. The primary focus of this work is to estimate the dispersed gas concentration levels around the potential release sources on offshore facilities. Computational fluid-dynamics (CFD) simulations were performed to study H2S/CO2 dispersion behavior. In the simulations, the Realizable k-є model for turbulence was used for the multicomponent gas flow, and the species-diffusion equation was solved for the gas-dispersion calculation. Parallel simulations were used to accelerate the computing time because system meshing generally has 1 to 2 million nodes. A series of scenarios was designed for the potential leak and relief locations, such as surface well testing (SWT) areas, relief lines (overboard), and flare boom, and with different wind directions, speeds, and gas-leak rates. The worst case scenarios were further studied. The results yielded 3D gas concentration distributions, including critical safety-concentration level profiles, pollution coverage area, and height.

Published: June 2015

Abstract
After experiencing massive lost circulation in an exploratory well in Colombia, it became necessary to drill without returns and stop the job upon various occasions of waiting for water. Upon completion of the job, water uptake limits were exceeded and various community relation issues were encountered, increasing both operational costs and nonproductive time (NPT). By the next well, the operator decided to develop a strategic plan to drill the well with the same scenario in the same location, but using a comprehensive strategy to help reduce the volume of water uptake while managing community relations and associated costs. The operator achieved a drill section in the well from the surface to 2,800 total ft, without additional water uptake, in less time. The logistical plan was executed in the field successfully, complying with the allowable uptake water permitted by the licensure without exceeding uptake limits. No NPT or health, safety, or environmental (HSE) incidents occurred during operations. No penalties or breaches of licensure were committed. No damage to the environment occurred. The community felt fulfilled that operational management protected its resources and the operator achieved a savings of nearly USD one million compared to the previous well. This strategy allowed analyzing a drilling fluid system alternative involving the use of aerated fluids to improve the operation and minimize the necessity to uptake water. The logistical plan developed helped build structures that currently support the operations of nearby wells, providing operational savings to execute drilling operations in the same area. Using the lessons learned from this operation, the operator successfully drilled two additional wells in the same area, implementing similar strategies (use of aerated fluids system) and complying with outlined environmental regulations. This helped the operator reduce operational costs. All personnel involved during operations were mindful of environmental impact and the importance of compliance with outlined environmental regulations.
Solving Delays, Inefficiencies And Increased Safety Risks In Facilities: A Breathing Air Case Study
Authors: Dowd D.. , Wallace T. J. , Daher E.. 
Published: June 2015

Abstract
The industry faces a number of challenges related to breathing air systems. Most high capacity breathing air systems typically have a large footprint and take up valuable real estate in an already crowded facility. Some operations require breathing air to support a large number of people simultaneously. Conventional cascade systems need to be replaced frequently with new, full cascades. This increases congestion and can potentially shut down work while the units are swapped out. There is also a high potential for costly accidents during transportation and when lifting cascades off the ground to elevated locations.
Conventional low volume breathing air solutions have very limited flexibility. This is a case study of a compact ten ft. by ten high pressure breathing air system that holds up to 68,000 standard cubic feet (scf) of breathing air. It was designed to enable fill-in-place technology. It also has high pressure lines that distributed breathing air to workers at elevated worksites. Through the fill-in-place technology, the system was able to eliminate work disruptions during air replacement. The cascade was refilled even as far as 300 ft away while personnel were using the system.
This case study presents an analysis of conventional and newer breathing air solutions and discusses in detail the significance of this innovation on how to deal with limitations and challenges facing the industry today. The case study outlines how to make facilities safer and more efficient by minimizing downtime, improving tool time and maintaining worksite safety at the highest possible levels.
Development of Bio-Oil Emulsion to Allow Realistic Testing of Oil Spill Control Equipment

Published: June 2015

Abstract
Accidental release of oil to the sea poses may have dire ecological consequences and serious economic ramifications, as recent events have shown. Spill control equipment as: booms, skimmers and oil trawls may protect sensitive areas and remove floating oil. This is subject to continuous technological development and innovation.
To support such development there is a pressing need to test new equipment under realistic conditions; in other words by release of oil to find out if can be successfully removed. Intentional release of crude oil to the sea will usually be taboo. If the crude is replaced by edible oil, reasons for restrictions are far less.
Subjected to wavy sea, most crudes will develop stable non-Newtonian emulsions of considerable stiffness. Using soybean oil and an emulsifier, stable bio-emulsion with similar density and rheological properties were developed. Microscopic image analyzes showed that the emulsions consisted of water droplets in the typical range 5-20 microns, surrounded by a thin oil film. The droplet approximately followed the lognormal distribution. The water content could be up to 70%, yet the emulsions were oil-continuous and very stable.
Obviously, the potential benefits of using such emulsions for equipment development and verification are high and the environmental impact probably small and possibly beneficial. So permission for limited tests at sea in August has been given by Norwegian authorities and was performed in north of the Vesterålen islands in September 2014.
Applied Advanced Control Systems for Electrostatic Dehydrators in the Upstream Oil Industry
Authors: Perez H. D. , Grandas G. Grandas , Perez-Rodriguez H.. 
Published: June 2015

Abstract
A linear unconstrained model predictive control (MPC) scheme has been designed to optimize the operation of dual frequency electrostatic dehydrators in the Colombian Rubiales and Quifa oil fields. This multi-objective controller optimizes operation by maximizing the amount of daily oil production, while maintaining the base sediment and water (BS&W) specification at the exit of the electrostatic dehydrator at or below 1.0%.
The designed controller uses models that describe the dynamics of the dehydrator system to meet the objectives described above. The model of the entire system consists of two empirical sub-models: one for the crude-steam heat exchangers upstream of the electrotreater and one for the treater. Each of these models is used to design an MPC controller for the corresponding subsystem. The electrotreater MPC works as the master controller, dictating crude temperature setpoints to the exchanger MPC. The exchanger MPC then adjusts the vapor flow valve opening to obtain the optimum temperature for the outlet BS&W specification. The electrotreater controller also adjusts the treater inlet/outlet flows and the transformer voltage setpoints to meet the desired objectives.
This control scheme allows for 1) less variability in the output BS&W, 2) maximized daily crude oil production, and 3) tighter control. The decrease in BS&W variability helps ensure that the product quality control and increases the rate of oil production by minimizing the need for further oil dehydration steps. In terms of OPEX, financial benefits are obtained by optimizing the dehydrator operation due to the reduction in the amount of costly emulsion breaking chemicals used in this and other stages of the dehydration process to ensure an effluent BS&W specification of 1.0%. In terms of CAPEX, this control scheme minimizes the need for additional infrastructure necessary to further dehydrate the oil produced to pipeline specifications.
This is the first time such a control scheme is known to have been developed for oil dehydration facilities. The approach proposed in this paper makes further implementation of advanced control systems an intriguing and promising venture that includes benefits such as increased oil production and decreased operating and capital costs.
Understanding, Bringing Closer, Integrating: Integration and Early Territory Articulation Model
Authors: Rojas Prada G. I. 
Published: June 2015

Abstract
Through this model, Ecopetrol seeks to understand how the territories of interest function, defining actions that make it possible to establish timely and effective liaison processes and integration, framed within the principles of Sustainable Development, generating relationships built upon legitimacy and trust.
In addition, the model seeks to built long-term regional visions on a collective basis to support the liaison process with stakeholders, identifying projects, managing alliances, strengthening the communities' capabilities; collaborating with the value chain's sustainability and contributing to the territories' sustainable development.
The model contemplates several tools to reach its objectives, which are developed in three processes: Reconnaissance, which carries out a comprehensive study of the company's territories of interest, contemplating the ecosystemic, economic, sociocultural and political dimension, delimiting and enabling a multidimensional interpretation through system dynamics; Integration, which forms part of the reconnaissance of territory and of plans that both the community and the company have visualized for the future. This vision is materialized by means of short, medium and long-term plans promoting the region's sustainable development through prospective exercises; Monitoring, which obtains a system to conduct a follow-up, by means of indicators, of the transformation of territory dynamics that could affect the company's activities, as well as the implemented strategies.
Through the application of this model in the southern part of the country, we are building alliances with regional organizations around our joint interest to achieve the sustainable development of the territory, which are articulated to long-term projects through territorial liaison processes based on social dialogue and the strengthening of the stakeholders' capabilities.
Modeling and simulating the dynamics in the territories where the organization's projects are carried out promote the understanding of the functionalities thereof through multidimensional and multiscale analyses, systemically focusing the management of the company's different departments on the different dimensions (ecosystemic, political, sociocultural and economic).
Challenges in Managing Solid Waste from Remote Sites in the Operation and Maintenance of the Pipeline Transportation System - Camise, Perú
Authors: Hernani J.. , Sulca G.. , Schuler M. Soria 
Published: June 2015

Abstract
The Camisea Pipeline Transportation System (PTS) crosses along three regions clearly differentiated in its 730 Km: forest, mountains and coast. Each of them has particular high social sensitivity and biolgocial diversity.
During pipeline operation and maintenance, different wastes are generated which must be disposed of in authorized sanitary or security landfills. There are not many and are remotely located from the generation points.
Waste management from remote generation points to authorized places involve a challenge from the logistic viewpoint, time, social and environmental responsibility, mainly due to the fact that operations in the forest are carried out under offshore conditions: carrying by air personnel, materials and wastes, thus complying with the access control plan of highly sensitivie social and environmental sectors of native communities, thus achiving compliance with the highest international standards related to the project.
Management of wastes at different work sites of the Right of Way starts with proper seggregation at the source. They are classified, labelled and registered, and then, they are transported to one of the 5 central storages strategically located along the three working sectors. Several air and/or land transportation means are used to move over 900 tons of hazardous and non hazardous wastes generated in the project.
An important factor implemented in waste management is compacting, which allowed for a reduction of over 30% of wastes transported, resulting in savings for the company.
Reception and conditioning in central storages follow safety and occupational health guidelines that allow to guarantee risk minimization and prevention.
Another strategy implemented as part of waste minimization is the implementation of fertilizing latrines, used in remote áreas to take advantage of waste water in organic matter environmentally usable.
Initiatives were implemented for reusing almost all organic wastes by transforming compost, reducing by 90% said waste, together with community development projects by using compost as raw material in agricultura in the areas of influence of the company.
