Accurate prediction of infill well production is crucial since the expected amount of incremental production is used in the decision-making process to choose the best infill locations. Making a good decision requires taking into account all possible outcomes and so it is necessary to quantify the uncertainty in forecasts. Many researchers have addressed the infill well location selection problem previously. Some of them used optimization algorithms, others presented empirical methods and some of them tried to solve this problem with statistical approaches. In this study, a reservoir simulation based approach was used to select infill well locations. I used multiple reservoir realizations to take different possible outcomes into consideration, generated probabilistic distributions of incremental field production and, finally, used descriptive statistical analysis to evaluate results. I quantified the uncertainty associated with infill location selection in terms of incremental field production and validated the approach on a synthetic reservoir model. Results of this work gave us the possible infill locations, which have a mean higher than the minimum economic limit, with a range of expected incremental production.

It is often difficult to quantify the drilling and recompletion potential in producing gas fields, due to large variability in rock quality, well spacing, well completion practices, and the large number of wells involved. Given the marginal nature of many of these fields, it is often prohibitively expensive to conduct conventional reservoir characterization and simulation studies to determine infill potential. There is a need for rapid, cost-efficient technology to evaluate infill potential in gas reservoirs, particularly tight gas reservoirs. Some authors have used moving window statistical methods, which are useful screening tools for identifying potential areas or groups of wells for further study. But the accuracy of the moving window method in very heterogeneous reservoirs is limited, based on the analysis of some authors. This study presents a new simulation-based inversion approach for rapid assessment of infill well potential. It differs from typical simulation inversion applications in that, instead of focusing on small-scale, high-resolution problems, it focuses on large-scale, coarse-resolution studies consisting of hundreds or, potentially thousands, of wells. In an initial application, the method employs well locations, production data, an approximate reservoir description and, accordingly, is able to identify potential areas or groups of wells for infill development quickly and inexpensively. Prediction accuracy can be increased commensurate with reservoir characterization effort, time and costs. Thus, the method provides a consistent basis for transition from screening studies to conventional reservoir studies.The proposed approach is demonstrated to be more accurate than moving window statistical methods in synthetic cases, with comparable analysis times and costs. In a bind validation study of a field case with 40 years of production history, the method was able to accurately predict performance for a group of 19 infill wells.

Successful residential infill is an important development model that benefits a community through reinvestment in older neighborhoods, retention of open space, and improved quality of life. However, local governments around the country are contending with problems created by infill homes that are incompatible with the existing neighborhood. This out-of-context development threatens the character of many older neighborhoods and often causes strong resident opposition to any new construction, to the point that some governments have imposed building moratoria to block all projects. Contextual infill standards and neighborhood conservation overlays are two regulatory tools that jurisdictions can use to guide infill construction that protect community character and reduce neighborhood opposition. In this report, the author provides a survey of how communities currently use these approaches and provides an assessment of their success at promoting compatible development in different infill scenarios. / text

Sustainable urban growth can be achieved in part by increasing density through infill development. Done right, infill development encourages already developed areas to become more diverse and livable, while limiting urban sprawl and all the public health, environmental, and infrastructure problems that accompany it. In Pima County’s 2015 update to the Comprehensive Plan, infill development is identified as a goal for land use policy. This study utilizes a Python script to build a model of the Hillside Development Overlay Zone (HDZ) to aid in removing zoning barriers to this goal. This a) improves the permitting process; b) encourages purchase of parcels outside of hillside areas and; c) encourages innovative design on hillside areas. The visualization is available on Pima County’s MapGuide website, allowing developers to make informed decisions about purchasing, permitting, and designing on HDZ parcels. In addition, this study uses a Kernel Density analysis to suggest areas where HDZ can be removed, without losing protection for mountainous areas. These suggestions are submitted to Pima County Development Services.

This work is a study of the relationship between frame, infill, and earth. A search of structure defining space through threshold. Ultimately, it proposes a structural frame as a collection of rooms. / Master of Architecture

The city block may be seen as the fabric of the urban environment. It is often a compacted form, divided only by changing facades and party walls. Boxes all in rows. There is an inescapable sense of enclosure. Architecture has the potential to unlock the box, allowing interaction between inside and out. The opening, be it a window, skylight, or void, becomes the way that the interior and exterior inform one another. The opening must not only relate to the street and city, but also to the sky and sun. It is an intangible element, created by the form and material that reside in proximity to it. Experiencing the intangible allows a connection to be made with the nature of the site. The opening, generated by form, mass, and material, in turn generates, through visual interaction and the play of light, space that informs and transcends. / Master of Architecture

Developing appropriate treatments for easel paintings can be complex, as many works are composed of various materials that respond in different ways. When selecting a filling material for these artworks, several properties are investigated including: the need for the infill to react to environmental conditions in a similar manner as the original material; the need for the infill to have good handling properties, adhesion to the original support, and cohesion within the filling material; the ability for the infill to withstand the stress of the surrounding material and; be as flexible as the original material to not cause further damage. Also, changes in colour or mechanical properties should not occur as part of the ageing process. Studies are needed on acrylic-based materials used as infills in conservation treatments. This research examines some of the chemical, physical, and optical changes of eleven filling materials before and after ageing, with the aim to evaluate the overall appropriateness of these materials as infills for easel paintings. The materials examined were three rabbit skin glue (RSG) gessoes, and seven commercially prepared acrylic materials, all easily acquired in North America. Chemical analysis was carried out with Fourier transform infrared (FTIR) spectroscopy and X-ray fluorescence (XRF), pyrolysis gas chromatography-mass spectroscopy (Py-GC/MS), and differential scanning calorimetry (DSC). Overall the compositions of the various materials examined were found to be in agreement with the available literature and previous research. This study also examined characteristics of these materials not described in previous works and, additionally, presented the compositions and behaviour of several commonly used materials with little literature description. After application of an ageing regimen, most naturally aged and artificially aged samples displayed small changes in gloss, colour, thickness, and diffusive behaviour; however, to evaluate these materials fully mechanical testing and environmental studies should be carried out. / Thesis (Master, Art Conservation) -- Queen's University, 2013-09-30 23:24:52.475

Residential infill development and the associated increases in impervious cover and stormwater runoff have the potential to overwhelm aging infrastructure causing erosion, flooding, and ecological degradation of waterways. The lack of greenfield sites available for new development around urban centers coupled with a desire for maintaining a traditional neighborhood aesthetic drives residential infill and replacement of existing smaller homes by significantly larger structures, minimizing open space available for stormwater mitigation. An analysis of residential infill development trends in Fairfax County was performed to characterize the effects of intensified development. Development patterns were identified and assessed using digitized impervious cover data extracted from aerial imagery of the study area for six selected years from 2002 to 2015. The average annual increase in percent impervious area was computed to be 0.3%. Redevelopment was found to be mainly occurring in areas zoned as lower-density residential. The spatial distribution of redevelopment showed trends of clustered increases as opposed to isolated events. The hydrologic analysis performed revealed that from 2002 to 2015, there was an 8,930 m3 (7.2 acre-ft) increase in stormwater runoff volume, 38% of which is contributed to by runoff generated from development that is considered exempted from regulation in Fairfax County. Additionally, there was a 28 kg/year (62 lb/year) increase in total phosphorus loads attributable to the change in impervious cover due to residential development throughout the study area. The results of this study provide a quantitative basis for municipalities to amend policies regulating residential development and its associated stormwater management. / Master of Science
