Physics-Guided Data-Driven Production Forecasting in Shales

Saputra, Wardana 11 1900 (has links)
In the early 21st century, oil and gas production in the U.S. was conjectured to be in terminal-irreversible decline. But, thanks to the advancement of hydraulic fracturing technologies over the last decade, operators are now able to produce two-thirds of U.S. oil and gas output from almost impermeable shale formations. Despite the enormous success of the ‘shale revolution’, there are still debates about how long shale production will last and if there will be enough to subsidize a meaningful transition to ‘greener’ power sources. Most official pronouncements of shale oil and gas reserves are based on purely empirical curve-fitting approaches or geological volumetric calculations that tend to largely overestimate the actual reserves. As an alternative to these industry-standard forecasting methods, we propose a more reliable, ‘transparent’, physics-guided and data-driven approach to estimating future production rates of oil and gas in shales. Our physics-based scaling method captures all essential physics of hydrocarbon production and hydrofracture geometry, yet it is as simple as the industry-favored Decline Curve Analysis (DCA), so that most engineers can adopt it. We also demonstrate that our method is as accurate as other analytical methods and has the same predictive power as commercial reservoir simulators but with less data required and significantly faster computational time. To capture the uncertainties of play-wide production, we combine physical scaling with the Generalized Extreme Value (GEV) statistics. So far, we have implemented this method to nearly half a million wells from all major U.S. shale plays. Since the results of our analyses are not subject to bias, policy-makers ought not to assume that the shale production boom will last for centuries.

Transit Objekt

Prinz, Bobi January 2012 (has links)
Transit Objects   In the Master Essay I argue around two existing levels in the works presented at the graduation exhibition. On the one hand, it is about influence; on the other hand it is about the phenotypes of purpose-ness. In the introduction, I describe the relationship between the shapes that I have come to call Transit objects, and their on the one hand ideological superstructure; on the other hand, the different aspects of their shapes regarding the imitation I, in creating the objects, performed. In the case with the objects shape-aspects, I stand on the thoughts that I found during my bachelor's work, that is, to express the phenotypes of purpose-ness. When it comes to influence, I speculate about how linguistics, and particularly a branch called neuro-linguistics, illustrates how the arguments that make up our world can be transformed. I use a meta-model and a conversation model as a tool to illustrate this. When I, like that, illustrate the plasticity of meaning, and cognition, I note Catherine Malabous taught (in her book What Should we do with our brain?) on the plasticity of the brain in relation to the neo-liberal systems of capitalism. She argues for how the brain has come to stand model for the organization of different types of networks. I hint the link to a future scenario where the desire to influence takes new forms and uses the latest brain research challenges, more specifically the use of ultrasound for the treatment of pain and other similar conditions. This also can be used as generating various types of seizures, pleasant or unpleasant. The next section in my text goes into the background of the artworks on display. I describe here my process. I also here describe the background to the proposal for public art in Gävle. Now follows a more detailed description of the series of works that I created during the Master's program. I begin with a description of the Phantom Objects 001-004, 2011, which basically is more linked to the bachelor's work. I describe this in the text because many of the aspects are still relevant in the series of works my master work consists of. Then I describe the EUR-pallet in Rosewood, 2011, presented at the graduation exhibition. EUR-pallet in Rosewood, is a work in which I shifted the scale of a Euro pallet to a scale of 1:2. In this way, it has moved into a “gray area” when it comes to its purpose. This is reinforced when the material is, unlike an ordinary Euro-pallet, here elevated to the veneer in Rosewood. I have "gilded" this very common design. EUR-pallets are included in global trade, or streams. They are durable and robust object with a distinct function. They are transit objects constantly in transit or waiting for new loads. I do these things manageable, further reified, and transparent. In this way, I open their innermost being and essence, the functional, and move it into a different light for a clearer sense of their mystery, clearer sense of their tangible presence and function in space and time. I give the shape a more open body language when the burden of function is eased. Which does not mean that the function is plundered, it is partially retained, inherent in the construction design, but stripped of its anonymity, strength and the standardized measure that makes it an effective part in a logistic machinery. Then I describe the work Billboard (STEALTH-monument for Joe Hill), 2012. This work is my proposal for public works in Gävle during the collaborative project between the Konstfack College of Arts and Gävle Art Centre (The collaboration is called Hello Gävle). It is presented as an advertising pillar, which measures approximately 15x30 centimetres (scale approx. 1:13) that I have sculpted and cast in aluminium. I emphasize this in Sweden common structure used for messages and announcements, and displaces the shapes purpose; I illustrate, unmask, isolate or "exalt" in this way it’s (in all its frivolity) concrete, concentrated form. In case of construction, the shape, in one copy, be at a scale of 1:1, that is about 3 meters tall and with each side about 1.3 meters wide. Then a description of the piece container, 2012. I saw a picture in a newspaper. I was dazed and said when I saw the picture, how beautiful it was the landscape of thousands of containers in different colours. For me there was something human and inhuman at the same time in that port. I do these constructions manageable, transparent and thus their enigmatic choreography and interior approaches me. Containers exist for transporting objects from different physical locations. The global circulation these constructions are organized in are well-planned and for an outsider hard to grasp. It is a diverse duplicated place where different actors meet and negotiate. Although there is something buried inside the container. It is ubiquitous, but at the same time exclusionary. This is almost the same inaccessibility as when it comes to the celestial bodies’ cyclical paths. Is there not something demanding, a form with such a clear function. A desire to be used in accordance with its intended context. As with the message, for example, from a billboard, it call to be understood in line with the context, but the global container flow are speaking without a sender. The clear bright colours. Red, blue, green, reminiscent of stained glass windows in churches. Are these containers, in fact, the holiest of places? One room, while at the same time thousands of rooms. The doors are opened and closed, and there is delivered a flood of heard prayers. One room, which in its variety is endless. A flexible place. A capitalist utopia. Next, a description of the work Carbon-bars, 2012. During the manufacturing process for Billboard (STEALTH-monument for Joe Hill), I made some experiences that made me interested in carbon as material in a future work. I imagined doing a variation of the billboard in coal. But after consideration and new experiences, I was aware of the bars. It was during my visit to the casting-industry where I saw the bars. Thereafter, the work was ready for fabrication The Carbon-bars are manufactured in an opposite logic than that of the EUR-pallet in Rosewood. Instead of "gild" the object I have here, "charcoaled" it, a form that can directly be read as being a bar. It is a paradoxical play with symbols of value. On the one hand the bar is generally associated with gold, on the other hand, the carbon for me associated with transience and uselessness without value. The human body consists of a number of kilograms of carbon. In the global economy, I am considering the "coin base" for a human. It seems in the banking crisis and its oil's wake consists of a 'charcoal-base", a "coal-human base." A man in the global market is priced for the weight in coal. In the final discussion I argue about my interpretation of the contemporary global flow of messages and objects in relation to Brian Holmes, Edward Bernays, Slavoy Zizek, Rosalyn Deutsche, Walter Lippman and Adam Curtis. From need to desire is a general explanation of how capitalism manages a market where basic needs are satisfied and hence, according to the logic of capitalism (but perhaps also human logic) new has to be created. Edward Bernay (who coined the term public relations as a euphemism for propaganda) was a genius when it came to this type of business: to create a "friendly arrangement” between the companies and the public. The amicable agreement Bernay talking about is, I think, in fact, the The Phantom Public Walter Lippman define. It's a public with the phenotypes of public working for a friendly agreement and arrangement between the consumers/ population and the profit hungry companies/ mafia. Brian Holmes points out Thomas Frank who argues that fashion designers and advertisers have their own existential interest in transforming the system, and that "… the result…” at least during the sixties, “…was a change of 'the ideology by which business explained its dominant position in national life"'. Here sounds Bernays amicable agreement again. An agreement continuously produced and as a result of the production is accompanied by Transit Objects.

Activation of lung epithelial cells by group 2 mite allergens

Österlund, Camilla January 2012 (has links)
Throughout many parts of the world house dust mites (HDM) are considered as a major source of indoor aeroallergens and they are powerful inducers of allergic diseases. Proteolytic HDM allergens are recognised as being able to directly activate respiratory epithelial cells and thereby actively participate in innate immune responses. Although several major HDM allergens lack proteolytic activity, their possible ability to similarly interact with epithelial cells is not known. The overall aim of this thesis was therefore to elucidate if and how major non-proteolytic group 2 allergens from different mite species interact with respiratory epithelial cells. The effects of the structurally related Der p 2, Der f 2 and Eur m 2 from different HDM species as well as the storage mite allergen Lep d 2 were studied in vitro using human respiratory epithelial cells. Also the non-proteolytic, but structurally dissimilar, Fel d 1 from cat, Can f 2 from dog, Bet v 1 from birch and Phl p 5a from timothy were studied. In this thesis evidence that major group 2 mite allergens activate bronchial epithelial cells is presented. Following allergen exposure the secreted amount of the inflammatory mediators G-CSF, GM-CSF, IL-6, IL-8, MCP-1, MIP-3α and sICAM-1 was increased. Surface expression of ICAM-1 was also increased following allergen exposure. Moreover, Fel d 1 and Can f 2 induced secretion of the same mediators from bronchial epithelial cells, representing two additional protein structures being able to directly induce cell activation. In experiments using specific inhibitors and siRNA transfection, it was shown that the mite allergens engage TLR4 and activation through MyD88, MAPK and NF-κB signal transduction pathways. In conclusion, the novel findings in this thesis provide knowledge on how major aeroallergens, in addition to their ability to provoke specific adaptive immune responses, may aggravate a respiratory airway disease by adjuvant-like activation of inflammatory responses in bronchial epithelial cells. This differs from previously reported allergen-induction of epithelial cells by the clear independency of proteolytic activation.

Comparison of Emperical Decline Curve Analysis for Shale Wells

Kanfar, Mohammed Sami 16 December 2013 (has links)
This study compares four recently developed decline curve methods and the traditional Arps or Fetkovich approach. The four methods which are empirically formulated for shale and tight gas wells are: 1. Power Law Exponential Decline (PLE). 2. Stretched Exponential Decline (SEPD). 3. Duong Method. 4. Logistic Growth Model (LGM). Each method has different tuning parameters and equation forms. The main objective of this work is to determine the best method(s) in terms of Estimated Ultimate Recovery (EUR) accuracy, goodness of fit, and ease of matching. In addition, these methods are compared against each other at different production times in order to understand the effect of production time on forecasts. As a part of validation process, all methods are benchmarked against simulation. This study compares the decline methods to four simulation cases which represent the common shale declines observed in the field. Shale wells, which are completed with horizontal wells and multiple traverse highly-conductive hydraulic fractures, exhibit long transient linear flow. Based on certain models, linear flow is preceded by bilinear flow if natural fractures are present. In addition to this, linear flow is succeeded by Boundary Dominated Flow (BDF) decline when pressure wave reaches boundary. This means four declines are possible, hence four simulation cases are required for comparison. To facilitate automatic data fitting, a non-linear regression program was developed using excel VBA. The program optimizes the Least-Square (LS) objective function to find the best fit. The used optimization algorithm is the Levenberg-Marquardt Algorithm (LMA) and it is used because of its robustness and ease of use. This work shows that all methods forecast different EURs and some fit certain simulation cases better than others. In addition, no method can forecast EUR accurately without reaching BDF. Using this work, engineers can choose the best method to forecast EUR after identifying the simulation case that is most analogous to their field wells. The VBA program and the matching procedure presented here can help engineers automate these methods into their forecasting sheets.

Ekonomická analýza měnového páru EUR/USD / Economic analysis of currency pair EUR/USD

Peťura, Michal January 2016 (has links)
This thesis deals with the relationship of exchange rate theory regarding the currency pair EUR / USD. The theoretical part defines the fundamental issue of exchange rates, exchange-rate regimes and the foreign exchange market, where the exchange rates are made. The crucial part of the theory is devoted to economic theories causing currency movements. In conclusion of the theoretical part attention is also given to econometric methods and statistics time series analysis. The analytical part of the thesis examines the short and long term relationships of purchasing power parity, the theory of parity of interest rates and monetary approach to the exchange rate for the currency pair EUR / USD. A regression analysis is used for investigating short-term relationships, and is applied to the relative changes in the value of the currency pair EUR / USD and the changes in the relative values of the theory of exchange rate determination. The long-term equilibrium relationship is analyzed by using a cointegration analysis, specifically the Engle-Granger and Johansen tests. The estimated results are evaluated and discussed in the final part of the thesis.

Oprávněnost intervencí ČNB na devizovém trhu

Hynková, Marie January 2018 (has links)
Hynková, M. The eligibility of the CNB interventions in the foreign exchange mar-ket. Diploma thesis. Brno: Mendel University in Brno, 2018. This diploma thesis deals with the monetary policy of the Czech National Bank after the financial crisis. The monetary policy of the CNB is compared with doings of the Federal Reserve and the European Central Bank. Attention is paid to the monetary policy of the CNB and to the reasons why the CNB has provided inter-ventions on the foreign exchange market in order to depreciate the CZK/EUR ex-change rate. The diploma thesis described in detail foreign exchange interventi-ons, which the CNB acceded on November 7, 2013, and subsequently abandoned them on April 6, 2017. The CNB wanted to influence the impending deflationary development in the country, so the diploma thesis also deals with the consequen-ces caused by the use of this non-conventional tool. The work also evaluates the benefits and costs of foreign exchange interventions. The empirical part of the diploma thesis demonstrates the relationship of inflation and the exchange rate CZK/EUR. There is also an appreciation of factors influencing the development of inflation during the intervention period.
