Gas hydrate accumulations at the Alaska North Sloge: total assessment based on 3D petroleum system modeling

The Alaska North Slope comprises an area of about 400,000 km2 including prominent gas and oil fields. Gas hydrates occur widely at the Alaska North Slope. A recent assessment by the USGS estimates 0.7-4.47 x 1012 m3 of technically recoverable gas hydrates based on well data and drilled hydrate accumulations. In spring 2012 a production field trial, testing CO2/N2 injection and depressurization, was conducted by USDOE/JOGMEC/ConocoPhillips at the Ignik Sikumi site. The 3D geological model of the Alaska North Slope developed by the USGS and Schlumberger is used to test the new gas hydrate module in the petroleum systems modeling software PetroMod®. Model results of the present extent of the gas hydrate stability zone (GHSZ) are in good agreement with results from well data. The model simulations reveal that the evolution of the GHSZ over time is primarily controlled by the climatic conditions regulating the extent of the permafrost during the last 1 Myr. Preliminary model runs predict the highest gas hydrate saturations near the major faults and at the bottom of the GHSZ, where thermogenic methane gas accumulates after migration through the most permeable stratigraphic layers (e.g. Sag River Sandstone Fm, Ivishak Fm). Gas hydrate saturations predicted for the Mount Elbert Stratigraphic Test Well and the Ignik Sikumi sites are basically controlled by the alternation of layers with different permeability and the fault properties (time of opening, permeability, etc). Further results including a total gas hydrate assessment for the Alaska North Slope will be presented during the conference

Приложение будет включать в себя пять блоков: развитие внимания, развитие логического мышления, изучение окружающего мира, изучение русской речи, изучение математики. Каждый блок отвечает за выполнение определенной функции и содержит в себе ряд заданий, представленных в игровой форме.The work is aimed at creating a correctional developmental application for mentally retarded children aged 7-12 years. The application will allow children with mental retardation to consolidate the knowledge gained in school in a playful way, learn basic actions with a computer, gain self-control skills, develop symbolic and planning functions of thinking and speaking. The application will include five blocks: the development of attention, the development of logical thinking, the study of the surrounding world, the study of Russian language, the study of mathematics. Each unit is responsible for performing a specific function and contains a number of tasks presented in a game form

Landform Evolution Modeling of Sedimentary Processes on Icy Worlds: the Cases of Hyperion and Helene

Sedimentary activity (erosion, transportation and deposition) is a major landscape-shaping process on many icy worlds of the outer solar system for which an understanding of this process is central to their geologic characterizations. Several recent studies, lead by the authors, have identified the effects of sedimentary activity on icy satellite landforms and recognized the role of mass wasting and volatile loss and redistribution in the evolution of these features. We apply state of the art, physics based, landform evolution modeling to icy satellite sedimentary landforms in order to fully quantitatively characterize how their morphologies change with time, and what their present appearances imply for the initial abundance and distribution of loose material, volatiles, and refractories in original pristine landforms. We will present results of our landform evolution modeling to the development of the landscapes of the Saturnian moons of Hyperion and Helene. Our current conclusions for Hyperion are that its unique appearance can be explained in part by the loss to space of ballistic ejecta during impact events. In order to create the smooth surfaces and the reticulate, honeycomb pattern of narrow divides between old craters, appreciable subsequent modification of crater morphology must occur through mass-wasting processes accompanied by sublimation, probably facilitated by the loss of CO2 as a component of the relief-supporting matrix of the bedrock. This mass wasting effectively destroys small craters, at least in part accounting for the paucity of sub-kilometer craters on Hyperion. Helenes unusual morphology consists of broad depressions (modified large craters) and a generally smooth surface patterned with streaks and grooves. The streaks appear to be oriented down-gradient, as are the grooves. This pattern suggests intensive mass-wasting as a dominant process. Our initial modeling of this surface suggests a Bingham-like rheological behavior for the loose down-slope moving material. Interestingly, as a Bingham flow, the models indicate that aperiodic "intermittent" behavior to be present, suggesting that periods of quiet steady landform evolution are punctuated short periods of active surface readjustment

Designing the Mission Operations for the Pointable Radiometer for Observation of Volcanic Emissions (PROVE) Pathfinder Payload

The PROVE Pathfinder CubeSat payload is a 2U Visual and TIR imaging payload optimized for observation of volcanic ash clouds for 3D reconstruction. Three of the main challenges for the mission operations of payload are optimization of the observation geometry (num. images, angles, etc.), data management of a high data rate payload, and observation scheduling for sporadic eruptions. Example solutions to these problems are presented belo

Recommendations for collecting and analysing migration-related determinants in public health research

Background: According to the definition of the German Federal Statistical Office, about every fourth person living in Germany has a so-called migration background (MB), i.e., the person or at least one of their parents was born without German citizenship. However, MB has been defined differently in many studies. Also, the MB summarises people in different living situations, making differentiated analysis in health science more difficult. This article formulates recommendations for the collection and analysis of migration-related, as well as social and structural, determinants of health. Indicators for capturing relevant determinants of health: As part of the Improving Health Monitoring in Migrant Populations project (IMIRA), the previous approaches to operationalise and measure migration-related determinants were revised based on literature research and exchange formats, such as workshops, meetings, congress contributions, etc. Instead of MB, the country of birth of the respondents and their parents, duration of residence, citizenship(s), residence status, and German language proficiency should be recorded as minimum indicators and analysed as individual variables. Further social and structural determinants, such as socioeconomic position, working and housing conditions, or self-reported discrimination, should be included. Conclusions: In order to describe health inequalities and to specifically identify the needs of people with a history of migration, a mutual and differentiated consideration of migration-related and social determinants of health is essential

The impact of ‘stop-go’ demand management policy on Britain's consumer durables industries, 1952-65

This article examines the impacts of British government ‘stop-go’ policy on domestic sales of consumer durables over the period 1952–65, via hire purchase restrictions and punitive Purchase Tax rates. Our analysis includes a general review of contemporary evidence regarding the impacts of these measures, a more detailed study of the television sector, and time-series econometric analysis for both televisions and a representative high-ticket labour-saving consumer durable: washing machines. We find that the restrictions had devastating impacts on Britain's consumer durables industries, preventing firms from fully exploiting economies of scale, reducing output growth and international competitiveness, and eroding industrial relations. Government officials were aware of these problems, but considered them a price worth paying to facilitate moves towards sterling convertibility and the re-establishment of the City as a leading financial and trading centre
