Capturing the Reservoir Uncertainty by Optimizing Gas Well Clean-Up Design in Deep Water Channel Slope Environment, Kutei Basin, Indonesia - A Case Study
Authors: Pradja Kurnia , Cook Dave , Budi Imam , Kurniawan Dian , Beretta Enzo 
Published: October 2015

Abstract
In 2009, a Gas reservoir discovery was made in the Deepwater of the Kutei Basin offshore East Kalimantan, Indonesia. The appraisal campaign continued through 2012 delineating both a main field (Jangkrik) and a satellite field to the north (Jangkrik NE). Three well tests were conducted during the appraisal phase confirming good permeability and high gas deliverability. Geologically, the field is characterized as a slope channel turbidite deposition system made up of many separate reservoirs. Some of the reservoirs amalgamate together in a channel complex system. The development scheme entails eleven subsea wells tied-back to a FPU for offshore processing of gas and condensates. The project is currently in execution phase and the development drilling and completion campaign is ongoing.
In October 2014 the first development well was drilled. The well was drilled from one of four drill centers in the north of the main field targeting for development two reservoir segments. Both segments will be completed using smart completion and frac pack to manage the potential for sand production during the production. This paper describes the integrated approach to model the clean-up design to optimize the cross discipline objectives and make critical decisions during the operational clean-up on the rig.
The clean-up design has been carried out to capture all possible reservoir risks related to the type of depositional. Not only the standard well testing software tool has been used, but also a 3D reservoir model has been developed to be able to predict the reservoir behavior during the clean-up and the build-up period. Furthermore as a validation the reservoir modeling is implemented to compare these two results using the well testing software. As the conclusion, this analysis helps the operators determine the best and proper way to operate the well and to prepare for the commissioning phase.
Deepwater gas development projects require reliable and consistent gas well deliverability to satisfy gas production targets and gas sales commitments. The clean-up of the high rate gas wells is critical after a successful completion to both establish the actual deliverability but also to minimize the production of completion fluid through the subsea system and to the FPU facility. The clean-up design was developed to meet all objectives for the project.
Development of Deepwater gas fields in Indonesia is in its early stages. The project is challenging due the number of different and separate reservoirs to be developed. Each well is designed to intersect and complete at least two reservoirs isolated and monitored separately through two Down-Hole Gauges (DHGs) that are installed in the intelligent completion design. The clean-up phase will utilize the intelligent completion equipment to clean-up and to test each reservoir independently.
An Analysis of Global Safety Trends in the Oil and Gas Industry - Impacts and Challenges in the Years Ahead
Authors: Daher Elie 
Published: October 2015

Abstract
This paper examines the safety trends influencing and shaping the oil and gas industry. From rising local content requirements to increasing shortage of skilled workers, rise in unconventional Oil and Gas to an increasing number of frontier oil producing countries, the growing role of Operational Excellence and the most common causes of incidents in the Oil and Gas sector, this paper will discuss facts, figures and case studies from around the world.
The paper was developed using secondary research based on industry reports such as the International Association of Oil and Gas Producers' (IOGP) Annual Safety Performance Indicators report to provide an analysis of fatal incident rates, total recordable injury rate, and lost time injury frequency. The research also referred to country profiles published by the US Energy Information Administration (EIA) including energy outlooks, analyses and projections. Information was culled from annual reports of international oil companies, technical papers published by the Society of Petroleum Engineers (SPE) as well as white papers by industry leaders, think tank groups and consulting firms.
While the presentation offers a bird's eye view of the safety industry at large, it delves deeper into safety issues outlining the scope of the various challenges and how they influence Health, Safety and Environment (HSE) management. It highlights the importance of heeding lessons learned from catastrophic incidents as well as the adoption of industry best practices and integration of Operation Excellence into the core business operations to prevent disasters. Concerns on unconventional production and the need for regulatory frameworks in emerging countries indicate that regulatory bodies need to catch up and fast track research efforts to regulate the unprecedented growth and expansion of the industry. When taken together as a whole, the global safety trends indicate that investments on safety or the lack thereof has a huge impact on business continuity and sustainability.
This paper was developed to give safety practitioners a better overview of the challenges, opportunities, new developments and trends shaping the global Oil and Gas industry.
Schmidt-Wenzel and Peng-Robinson Equations of State for CO2-Hydrocarbon Mixtures: Binary Interaction Parameters and Volume Translation Factors
Authors: Deo M. D. , Nutakki R. , Orr F. M. 
Published: October 2015

ABSTRACT
Two- and three-phase equilibria in binary mixtures of carbon dioxide with hydrocarbons have been studied using the Peng-Robinson equation of state [PREOS] and the Schmidt-Wenzel equation of state [SWEOS]. The CO2 - hydrocarbon mixtures studied include examples with normal alkanes, cycloalkanes and a number of aromatic compounds. Particular attention has been paid to the representation of the phase behavior of mixtures containing aromatic and naphthenic compounds. Phase compositions and densities for a variety of binary mixtures reported in the literature have been calculated, and some systems exhibiting three-phase behavior [L1-L2-V] have been modeled. Using a nonlinear least squares algorithm, optimum binary interaction parameters for a number of CO2-hydrocarbon systems were determined for both the SWEOS and the PREOS.
The interaction parameters for the PREOS and the SWEOS were very similar except in the case of n-alkanes heavier than C19. For alkanes lighter than heptane, the interaction parameter increases with temperature; for the intermediate alkanes (up to nonadecane) it remains constant with temperature and for heavier alkanes decreases with temperature. For aromatics and naphthenics no definite trend is observed. For n-alkanes, as the carbon number is increased the interaction parameter decreases (up to carbon number 10), levels off (carbon number 19) and begins to decrease again. With regard to the effect of structure and size of aromatic and naphthenic compounds, no specific trend was discerned.
After the phase compositions were matched using the optimum interaction parameters, a volume translation technique was used to match the liquid phase densities. SWEOS performed much better than PREOS in predicting the liquid phase densities for mixtures with heavy hydrocarbon components. With SWEOS, the volume translation was required only for mixtures containing hydrocarbons heavier than C16. For the PREOS volume translation was required for hydrocarbon components greater than C8.
Effect of Heterogeneity on Buckley-Leverett Displacement
Authors: Chang J. , Yortsos Y. C. 
Published: October 2015

ABSTRACT
The Buckley-Leverett (B-L) equation has been routinely used for the description of immiscible displacement in laboratory operations, and for parameter estimation and prediction. The recent resurgence of interest on effects of heterogeneity, however, has led to a serious challenge of the validity of many of the traditional theories. For the case of B-L displacement, most studies have examined heterogeneity effects originating from viscous fingering phenomena.
In this paper we present a numerical investigation of the effects of capillary heterogeneity, induced by a variation of the permeability in the direction of displacement. It is shown that for a medium of rapid enough permeability variation, the associated capillary effect is not negligible, even at the relatively high rates, where the B-L theory is typically valid. This effect manifests itself as a position-dependent addition to the fractional flow curve, and contrary to ordinary capillary effects, it is not limited to the saturation shock front.
We study the resulting equation for a variety of heterogeneity forms, including uncorrelated and correlated variations. It is found that, although it has a negligible effect on the recovery variables, heterogeneity affects significantly the saturation profiles. The latter closely follow the permeability variation at the points of heterogeneity, and conform to the B-L predictions, otherwise. The saturation response is found to be higher for more unfavorable mobility, oil-wet conditions and for less spatially correlated heterogeneity. The results may be useful in the interpretation of laboratory saturation profiles, in the identification of heterogeneity, and in the estimation of parameters such as relative permeabilities, in heterogeneous systems.
A New General Pressure Analysis Procedure for Slug Tests
Authors: Peres A. M. M. , Onur M. , Reynolds A. C. 
Published: October 2015

Abstract
A new method for determining formation flow capacity and skin factor from slug test data is presented. The new procedure is based on an exact deconvolution equation that converts the measured slug test pressure data into an equivalent pressure response that would be obtained if the well were produced at a constant surface flow rate. The new technique does not require the knowledge of the sandface flow rate and does not depend on the flow regime which exists within the reservoir. This procedure also yields the equivalent pressure derivative of the constant surface flow rate wellbore storage and skin pressure solution without applying numerical differentiation. After the constant surface rate pressure data and its derivative are generated by our procedure, the converted data can be analyzed by using existent wellbore storage and skin type curves for the particular reservoir model represented by the data. Therefore, slug test type curves are no longer needed. However, if the duration of the slug test is short, most of the converted data will fall on the unit slope line of the conventional constant rate wellbore storage and skin type curves, and thus, it will be difficult to obtain a unique type-curve match. For such cases, it is shown that the well known rate normalization procedure can be applied to greatly improve the reliability of the analysis. It is also shown that once the flow geometry is properly identified, the traditional superposition method (convolution) can be applied to the converted pressure data. A field case illustrating the reliability of the new method and its advantages over the traditional slug test analysis procedures is presented.
This paper is dedicated to Dr. Henry J. Ramey, Jr. in deep appreciation of his profound and inspirational contributions to the fields of pressure transient analysis and reservoir engineering.
Conservative Reporting and Securities Class Action Lawsuits
Authors: Ettredge Michael L. , Huang Ying (Julie) , Zhang Weining 
Published: October 2015

SYNOPSIS
Positive accounting theory predicts that conservative financial reporting averts GAAP-based litigation. However, very little empirical evidence addresses whether and how accounting conservatism provides these benefits. Using a sample of lawsuits against public companies for alleged violations of U.S. GAAP, we examine the association of accounting conservatism with subsequent initiation of lawsuits and with four litigation outcomes: market reactions to lawsuits, duration of lawsuits, dismissals of lawsuits, and penalties approved by courts. We find that firms with greater degrees of conditional conservatism experience more favorable consequences on all five dimensions of litigation occurrence and outcomes. Several measures of unconditional conservatism are not associated with the litigation variables. Our study provides new empirical evidence supporting Watts's (2003a) litigation explanation for accounting conservatism.

Abstract
Objective—To describe the outcome of full-thickness skin grafts used to close skin defects involving the distal aspects of the limbs in cats and dogs and identify factors associated with outcome.
Design—Retrospective case series.
Animals—20 cats and 32 dogs with a skin defect involving the distal aspect of a limb that received 58 full-thickness skin grafts between 2005 and 2012.
Procedures—Data regarding patient signalment, location and cause of the skin defect, surgical and anesthetic duration, and postoperative bandaging protocol were obtained from the medical records. Graft outcome was assessed by interpreting descriptions in the records; skin viability over ≥ 75% of the graft area between 7 and 14 days after surgery was considered a successful outcome.
Results—For 4 of the 58 grafts, graft outcome could not be determined from the medical record. For the remaining grafts, success rate was significantly higher for grafts placed in cats (17/22 [77%]) than in dogs (12/32 [38%]). The overall complication rate was 50%; complications included skin graft failure, donor site dehiscence, and bandage-induced sloughing of skin adjacent to the graft recipient site. In addition to species, anatomic location of the skin defect was identified as a prognostic indicator of graft outcome.
Conclusions and Clinical Relevance—Full-thickness skin grafting had a higher success rate in cats than in dogs. Skin grafts applied to the antebrachium, compared with other locations on the distal aspects of the limbs, were associated with a poorer prognosis.
Transmit/Receive (T/R) Modules—Key Elements for Phased Array Antennas
Authors: Oppermann Martin , Schroth Joerg , Thurow Felix 
Published: October 2015

Modern active electronically steered antennas (AESA) operate in different platforms and systems. Inside EADS/CASSIDIAN, the focus on X-band antennas today is on airborne and fighter nose radars, in satellite based SAR antennas (synthetic aperture radar) for earth observation, and ground surveillance and security radars.
Active antennas are assembled with hundreds or even thousands of transmit/receive modules. This paper will describe an example of a so-called standardized module solution based on LTCC package technology. State-of-the-art modules are assembled with active components such as MMICs realized in GaAs technology, for example, the low noise amplifier (LNA) and the high power amplifier (HPA), silicon based devices, and passives. Assembly technologies are optimized for high yield series production inside CASSIDIAN MicroWave Factory. New semiconductor technologies, such as GaN (gallium nitride) are enablers for a new transmit/receive module generation. GaN/SiC based MMICs with higher power density compared with GaAs-based devices are technological challenges for innovative thermal management solutions and assembly alternatives. GaN power devices are soldered on modern heat sink materials with high thermal conductivity and matched CTE (between the MMIC and the heat sink).
The results of thermal simulations comparing different heat sink materials in combination with soldering techniques will be discussed and an optimized solution will be shown. Another type of transmit/receive module technology based on RF-PCB and packaged MMICs will be discussed. Future applications of ground-based security radars, active antenna products with a one-dimensional array, and the need for cost-effective solutions seem to be a good fit for SMD-based products. Different packages, for example, QFN (quad flat pack no lead) and ceramic based (HTCC), mainly for power devices will be shown and compared.
Handwriting Without Tears®: General Education Effectiveness Through a Consultative Approach
Authors: Donica Denise K. 
Published: October 2015

Abstract
OBJECTIVE. This study explores the effectiveness of the Handwriting Without Tears® (HWT) kindergarten printing curriculum in general education through a consultative approach with occupational therapy.
METHOD. One cohort of students was the control (n = 19), whereas two other cohorts were experimental groups learning printing through the HWT curriculum (n = 20 each). The Test of Handwriting Skills–Revised (THS–R) was used to collect end-of-year legibility scores for all cohorts.
RESULTS. Both experimental groups individually and both experimental groups combined into one group outperformed the control group on all 10 of the THS–R subtests—scoring significantly higher (p &lt; .05 using analysis of covariance controlling for age and gender) on 6 of the subtests for the former and 7 for the latter—and on overall score. Large treatment effects were found for the standard score for each experimental group (d = 0.81, 1.03, and 1.00).
CONCLUSION. This study supports the consultative role of occupational therapy with teachers in general education for handwriting curriculum implementation and the success of HWT for printing instruction.
The Ride Down Mt. Morgan: Miller's Critique of Libido through Ibsen's Method of Causation
Authors: Livesay Lewis 
Published: October 2015

Abstract
The impetus for The Ride Down Mt. Morgan issues from Miller's divided subjectivity in the fifties. Timebends portrays its author responding to social rejection by temporarily living for self, immersed in the instinctive life of libido. Lyman Felt grows out of that memory of inexorable, excessive passion. Lyman represents the Nietzschean Superman, living beyond good and evil. While most interpreters criticize Lyman's duplicity, a consensus identifies with Lyman's refusal to conform to the strictures of conventional society. Adopting various strategies of paradox, ambiguity, or undecidability, interpreters find Ride to diverge from Miller's earlier works in suspending judgment and celebrating openness. I do not. Ride is driven as relentlessly as Miller's early plays by Ibsen's law of causality. Innate within this dramatic theory of temporal justice lies a critique in which Ride judges Lyman as intently as Salesman judges Willy for a betrayal of those who deserved but were denied love.

Rastreando corpos, produzindo sexos: a inserção da hiperplasia adrenal congênita no teste do pezinho
Authors: Freitas Janaina , Machado Paula Sandrine 
Published: October 2015

<p>O presente artigo busca refletir sobre o modo pelo qual as intersexualidades estão sendo produzidas e manejadas em um contexto em que as novas biotecnologias constituem ferramentas cruciais no processo de remodelação dos corpos e de produção de subjetividades. Para tanto, a partir de uma “etnografia de arquivo”, são analisados artigos científicos nacionais oriundos da área biomédica que abordam a triagem neonatal da Hiperplasia Adrenal Congênita (HAC), citada na literatura médica como a causa mais recorrente de intersexualidade, e sua inserção no Programa de Triagem Neonatal (Teste do Pezinho) no Brasil. Os resultados até então obtidos apontam para uma série de controvérsias em relação à inserção dessa condição nos programas de triagem, tais como um elevado número de casos “falso-positivos” e o fato de a mesma não representar necessariamente um risco à vida dos sujeitos (um dos critérios importantes para inclusão nas triagens).</p>

Vontades e leis naturais – liberdade e determinismo no positivismo comtiano
Authors: Lacerda Gustavo Biscaia 
Published: October 2015

<p>Nas Ciências Sociais, o "positivismo" de modo geral implica naturalismo, <em>i</em>. <em>e</em>., objetivismo e determinismo. No Positivismo comtiano, porém, as leis naturais são compatíveis com subjetividade e historicidade, devido a uma série de motivos: (1) pressupõe-se a intervenção humana (afinal, conhecem-se as leis para melhor agir); (2) as Ciências Sociais, ou melhor, na terminologia comtiana, a Sociologia é uma das mais complexas ciências e, portanto, é uma das mais modificáveis em suas aplicações e manifestações concretas; (3) o acúmulo teórico, metodológico, histórico e moral da Sociologia permite-lhe e até a obriga a modificar os métodos e as teorias das Ciências Naturais. Assim, há amplos vínculos entre Epistemologia, Sociologia e política prática, em particular via idéia de "liberdade de ação", o que ordinariamente resulta na dicotomia determinismo-vontade. Interessa aí o conceito comtiano de "vontade positiva": vista inicialmente como teológico-metafísica, ela foi introduzida na fase mais madura de Comte, em que a preocupação não era estabelecer as condições de cientificidade e as características da Sociologia, mas já elaborar os termos concretos da intervenção humana na sociedade e no mundo. Dessa forma, o presente artigo apresentará as etapas do conceito comtiano de "vontade", conforme exposto acima, relacionando-o também com o conceito de "liberdade filosófica" (ou seja, a própria possibilidade de intervenção humana no mundo). </p>
