<p>North American bridge design is dominated by a culture of risk aversion and economic constraint. While objectives of safety and efficiency should be the baseline of any project, they are sometimes set as the sole benchmarks for a successful bridge design within the North American context. When the end game is to simply meet the baseline of safety and efficiency, goals related to user experience and aesthetic impacts are often considered superfluous. This paper showcases lessons learned from designing within this context.</p><p>Stories from bridge designs showcase the ups and downs of bootstrapping higher design goals into footbridge projects in the Wild West.</p>

The Impact

This paper summarises workshop discussions at the 5th international MYCORED meeting in Ottawa, Canada (June 2012) with over 200 participants representing academics, government and industry scientists, government officials and farming organisations (present in roughly equal proportions) from 27 countries. Workshops centred on how mycotoxins in food and feed affect value chains and trade in the region covered by the North American Free Trade Agreement. Crops are contaminated by one or more of five important mycotoxins in parts of Canada and the United States every year, and when contaminated food and feed are consumed in amounts above tolerable limits, human and animal health are at risk. Economic loss from such contamination includes reduced crop yield, grain quality, animal productivity and loss of domestic and export markets. A systematic effort by grain producers, primary, transfer, and terminal elevators, millers and food and feed processers is required to manage these contaminants along the value chain. Workshops discussed lessons learned from investments in plant genetics, fungal genomics, toxicology, analytical and sampling science, management strategies along the food and feed value chains and methods to ameliorate the effects of toxins in grain on animal production and on reducing the impact of mycotoxins on population health in developing countries. These discussions were used to develop a set of priorities and recommendations.

Abstract Evaluating Electrical Submersible Pumps (ESPs) [SS1] [NA2] run-lives and performance in unconventional well environments is challenging due to many different factors -including the reservoir, well design, and production fluids. Moreover, reviewing the run-lives of ESPs in a field can be rather complex since the run-life data is incomplete. Often ESPs are pulled while they are still operational, or the ESP has not been allowed to run until failure. These are some of the complications that arise when gauging ESP performance. A large dataset of ESP installs was assessed using Kaplan-Meier survival analysis for the North American unconventional application to better understand those factors that may affect ESP run lives. The factors were studied including but are not limited to the following: Basin and producing formation Comparing different ESP component types such pumps and motors, and new or used ESP components Completion intensity of the frac job (lb/ft of proppant) Kaplan-Meier survival analysis is one of the commonly used methods to measure the fraction or probability of group survival after certain time periods because it accounts for incomplete observations. Using Kaplan-Meier analysis generates a survival curve to show a declining fraction of surviving ESPs over time. Survival curves can be compared by segmenting the runlife data into buckets (based on different factors), therefore to analyze the statistical significance of each and how they affect ESP survivability. Kaplan-Meier analysis was performed on the aforementioned dataset to answer these questions in order to better understand the factors that affect ESP runlives in North American unconventional plays. This work uses a unique dataset that encompasses several different ESP designs, with the ESPs installed in different North American plays. The observations and conclusions drawn from it, by applying survival analysis, can help in benchmarking ESP runtimes and identifying what works in terms of prolonging ESP runlife. The workflow is also applicable to any asset in order to better understand the drivers behind ESP runlife performance.

Local Operators

The logistical challenges of drilling in the Surat and Bowen basins, and the high operational costs allied to an oil price downturn, is forcing the CSG to LNG players in Queensland to reinvent their delivery models. The concept of a drilling factory has been the holy grail of the oil and gas industry for many years, and many local operators have turned their attention to the lessons learned by the North American shale players. These companies, with virtually no increase in capital costs, were able to improve time to drill, wells per rig and total distance drilled by 50–150% in fewer than five years. This revolution has been achieved not only with the advent of improved drilling technology but also the use of data-driven productivity and automation. Leveraging the experiences of North American companies, local operators are embracing the use of analytics to boost operational efficiencies and improve the safety of their operations. APLNG, for example, has used analytics to integrate multiple aspects of planning and operations to optimise field development for future phases of the project. As the volume of wells continues to increase, more supply chain related issues will require mitigation. Analytics solutions can assist not only in the isolation of wellbore-related non-productive time issues and reduce drilling cycle times for individual wells, but also to use the best tools and techniques in only the best parts of the field.
