Reservoir simulations are used to forecast the long-term gas production from hydrate reservoirs. In present work, we explore different well placements and configurations analyze strategy for an oceanic, unconfined, class-2, reservoir using in-house three-dimensional finite volume simulator. past, depressurization in unconfined class-2 reservoirs, isolation of aquifer zone by placement is sugges...

Original manuscript received for review 15 December 2010. Revised manuscript received for review 12 May 2011. Paper peer approved 15 July 2011. Summary Subsurface geology is highly uncertain, and it is necessary to account ...

The adequate location of wells in oil and environmental applications has a significant economical impact on reservoir management. However, the determination of optimal well locations is both challenging and computationally expensive. The overall goal of this research is to use the emerging Grid infrastructure to realize an autonomic dynamic data-driven self-optimizing reservoir framework. In th...

Optimum implementation of non-conventional wells allows us to increase considerably hydrocarbon recovery. By considering the high drilling cost and the potential improvement in well productivity, well placement decision is an important issue in field development. Considering complex reservoir geology and high reservoir heterogeneities, stochastic optimization methods are the most suitable appro...

This research proposes a framework for determining the optimum location of an injection well using an inference method, artificial neural networks and a search algorithm to create a search space and locate the global maxima. A complex carbonate geothermal reservoir (Kizildere Geothermal field, Turkey) production history is used to evaluate the proposed framework. Neural networks are used as a t...

This paper explores the central role played by schools in introducing students to a positive experience of justice and community. Issues in the current educational context that impact on the introduction of restorative practices into schools are discussed. A pilot project to assess the value of the process of Community Conferencing into schools within the State of Victoria, Australia is placed ...

Recent ecosystem service models have placed biodiversity as a central factor in the processes that link the natural environment to health. While it is recognized that disturbed ecosystems might negatively affect human well-being, it is not clear whether biodiversity is related to or can promote "good" human health and well-being. The aim of this study was to systematically identify, summarize, ...

Determining optimal locations and operation parameters for wells in oil and gas reservoirs has a potentially high economic impact. Finding these optima depends on a complex combination of geological, petrophysical, flow regimen, and economical parameters that are hard to grasp intuitively. On the other hand, automatic approaches have in the past been hampered by the overwhelming computational c...

BACKGROUND AND OBJECTIVES Each year, nearly 1% of US children spend time in foster care, with 6% of US children placed in foster care at least once between their birth and 18th birthday. Although a large literature considers the consequences of foster care placement for children's wellbeing, no study has used a nationally representative sample of US children to compare the mental and physical h...

We hypothesized that prospective changes in social identity that involve transitioning out of a currently valued group would be associated with negative expectations regarding future states, but that this effect would be mitigated among individuals who expect to belong to a future in-group of similar importance. Consistent with predictions, strongly identified young adults in two studies projec...
