Integrated reservoir modeling has become an important part of day-to-day decision analysis in oil and gas management practices. A very attractive and promising technology is the use of time-lapse or 4D seismic as an essential component in subsurface modeling. Today, 4D seismic is enabling oil companies to optimize production and increase recovery through monitoring fluid movements throughout the reservoir. 4D seismic advances are also being driven by an increased need by the petroleum engineering community to become more quantitative and accurate in our ability to monitor reservoir processes. Qualitative interpretations of time-lapse anomalies are being replaced by quantitative inversions of 4D seismic data to produce accurate maps of fluid saturations, pore pressure, temperature, among others. Within all steps involved in this subsurface modeling process, the most demanding one is integrating the geologic model with dynamic field data, including 4Dseismic when available. The validation of the geologic model with observed dynamic data is accomplished through a "history matching" (HM) process typically carried out with well-based measurements. Due to low resolution of production data, the validation process is severely limited in its reservoir areal coverage, compromising the quality of the model and any subsequent predictive exercise. This research will aim to provide a novel history matching approach that can use information from high-resolution seismic data to supplement the areally sparse production data. The proposed approach will utilize streamline-derived sensitivities as means of relating the forward model performance with the prior geologic model. The essential ideas underlying this approach are similar to those used for high-frequency approximations in seismic wave propagation. In both cases, this leads to solutions that are defined along "streamlines" (fluid flow), or "rays" (seismic wave propagation). Synthetic and field data examples will be used extensively to demonstrate the value and contribution of this work. Our results show that the problem of non-uniqueness in this complex history matching problem is greatly reduced when constraints in the form of saturation maps from spatially closely sampled seismic data are included. Further on, our methodology can be used to quickly identify discrepancies between static and dynamic modeling. Reducing this gap will ensure robust and reliable models leading to accurate predictions and ultimately an optimum hydrocarbon extraction.

<p>Syftet med vår undersökning är att undersöka hur invandrare beskriver sina upplevelser under sina första år i den svenska skolan. Datainsamlingen har skett genom intervjuer med fyra</p><p>elever, fyra lärare samt fem föräldrar.</p><p>Studien utgår från följande fråga:</p><p> Hur integreras eleverna med utländsk bakgrund i den svenska skolan?</p><p> Hur bidrar läraren till att elever med utländsk bakgrund ska få en bra integration?</p><p> Hur hjälper föräldrar sina barn att integreras i den svenska skolan?</p><p>Resultaten från undersökningen visar att elever med utländsk bakgrund har skilda upplevelser från integration i svenska skolan. Några elever och föräldrar ansett det var enkelt och andra betydligt svårare. Skillnaden mellan de elever och föräldrar vi intervjuade är att vissa accepterade det nya landet och kulturen ganska omgående då de började i skolan, medan de andra hade svårare att acceptera det nya landet. För dem som var positiva, gick språket enklare att lära sig och det gjorde att eleven fick en bättre integration i skolan. Däremot för eleverna som beskrev sin integration lite svårare, tog det längre tid att acceptera det nya landet och på så sätt tog det även längre tid att behärska det svenska språket och alla andra viktiga aspekter i skolan som t.ex. mat, regler och schema.</p>

<p> </p><p>RECODER is a Java framework aimed at source code analysis and metaprogramming. It works on several layers to offer a set of semi-automatic transformations and tools, ranging from a source code parser and unparser, offering a highly detailed syntactical model, analysis tools which are able to infer types of expressions, evaluate compile-time constants and keep cross-reference information, to transformations of the very Java sources, containing a library of common transformations and incremental analysis capabilities.</p><p>These make up an useful set of tools which can be extended to provide the basis for more advanced refactoring and metacompiler applications, in very different fields, from code beautification and simple preprocessors, stepping to software visualization and design problem detection tools to adaptive programming environments and invasive software composition.</p><p>The core system development of RECODER started in the academic field and as such, it was confined into a small platform of users. Although a powerful tool, RECODER framework lacks usability and requires extensive and careful configuration to work properly.</p><p>In order to overcome such limitations, we have taken advantage of the Eclipse Integrated Development Environment (Eclipse IDE) developed by IBM, specifically its Plugin Framework Architecture to build a tool and a vehicle where to integrate RECODER functionalities into a wide-used, well-known platform to provide a semi-automated and user-friendly interface.</p><p>In this bachelor thesis we will document how we have integrated RECODER into an Eclipse plug-in to perform a “proof of concept” transformation of an Eclipse Java Project, directly mapping the Eclipse-generated configuration of the project into RECODER's to automate the tedious task of manually configuring RECODER.</p><p> </p>
