The transportation industry is amidst a technological transformation to identify and adopt alternative sources of energy to power vehicles due to environmental factors. We examine the Metropolitan Transit Authority (MTA) buses since they operate in the city on a continuous cycle with increased coverage during peak transit times. We focus on the B63 bus route and perform a feasibility study to determine primarily whether wireless charging at specifically designated bus stops throughout the city can help to increase the feasibility of electric buses for city use both from an operational standpoint. We propose a framework that consists of a probabilistic model to capture the nature of the data and formalizing the feasibility study as an optimization problem. Using this framework we utilize the history of the system and the properties of the technology to find suitable locations for electric chargers without disrupting the operation of the system. We provide a framework that demonstrate...

The exploration and production (E and P) business is in the midst of a major transformation from an emphasis on cost-cutting to more diverse portfolio management practices. The industry has found that it is not easy to simultaneously optimize net present value (NPV), return on investment (ROI), and long-term growth. The result has been the adaptation of quantitative business practices that rival their subsurface geological equivalents in sophistication and complexity. The computational tools assess the risk-reward tradeoffs inherent in the upstream linkages between (1) the application of advanced technologies to improve success in exploration and in exploitation (reservoir evaluation, drilling, producing, and delivery to market) and (2) the maximization of both short- and long-term profitability. Exploitation is a critical link to the industry`s E and P profitability, as can be seen from the correlation between earnings growth of the international majors and production growth. The p...

Concern for the environment and energy security is changing the way we think about energy. Grid-enabled pas- senger vehicles, like electric vehicles (EV) and plug-in hybrid electric vehicles (PHEV) can help address environmental and energy issues. Automakers have recognized that electric drive vehicles are critical to the future of the industry. However, some challenges exist to greater adoption: the perception of cost, EV range, access to charging, potential impacts to the grid, and lack of public awareness about the availability and practicality of these vehicles. Although the current initial price for EV's is higher, their operating costs are lower. Policies that reduce the total cost of ownership of EVs and PHEVs, compared to conventional internal combustion engine (ICE) vehicles, will lead to faster market penetration. Greater access to charging infrastructure will also accelerate public adoption. Smart grid technology will optimize the vehicle integration with the grid, al...

4-D reservoir monitoring is a cost-effective way to expand revenues throughout the development history of reservoirs through tracking and monitoring of oil, gas and water drainage patterns over time. Bypassed pay can then be targeted and remediation programs planned, increasing recovery efficiency of oil-in-place to previously unheard-of-levels that are expected to approach 70% by early next century. This added efficiency comes from a fundamental paradigm shift in the way that oil fields are produced--spacetime monitoring of oil fields.

The concept of using multiple seismic datasets to image changes over time in oil and gas reservoirs, which the authors term 4-D, is not new. 4-D experiments date to the 1970s. To understand why 4-D will finally mature in the next several years into a new production paradigm for operators and service companies requires an understanding of both the methodology of 4-D and the market it plays into. Understanding these keys also gives insight into the shape of this new market. In this article the authors discuss their perceptions of these keys to understanding ``Why 4-D now?``

This first part of a six-part series explains how 4-D was developed, and how any company can take advantage of this new technology. Actual seismic response at various times in the life of a producing field are used to illustrate how 4-D technology is applied. Bypassed production is identified, and improved reservoir management is the end result.

One of the most complex problems in earth sciences is that of the determination of fluid flow behavior such as flow pathways, flow velocity and/or hydrologic conductivity in a heterogeneous subsurface. Information on fluid flow behavior (both present and predicted) is needed for the determination of the size and shape of groundwater recharge areas, the assessment of contamination impact of spills and plumes and the planning and assessment of remediation efforts. For all these problems it is recognized that a good knowledge of the 3D values of hydrologic conductivity is essential, yet most often the only knowledge available on the hydrologic conductivity is that deduced from a number of sampling wells and pumping tests experiments. These experiments only give a (poor) bulk approximation of the hydrologic conductivity, and consequently the predictions of fluid flow behavior based on these approximations are more often than not unsuccessful.

Tracking the flow of oil, gas, and water in real-time while reservoirs are being drained is now possible through the emergence of rugged downhole sensors, the Internet, high bandwidth satellite and fiber communications and rapid middleware wrapping of software applications. The question is what information delivers economic return on the investment required. The good news is that all along the value chain, prices are coming down because of commercial pressures from outside the energy business. For example, Direct PC will likely drop the cost and increase the bandwidth of satellite communications to remote locations by an order of magnitude over the next few years. Application The manufacturing process by which we produce energy is being reinvented like we have never before experienced in this business. The oil and gas field of the future will be part of a much larger Information Technology (IT) network. Each field will be a wired, internet-connected, real-time monitored, remotely co...

We have imaged 4D seismic amplitude and impedance differences between 3D seismic surveys conducted in 1988, prior to production, and in 1994, when about half of the recoverable hydrocarbons had been produced, to attempt to quantify the variations in fluid saturations with time within turbidite reservoirs in a Gulf of Mexico oil field. The mission of this 4D seismic monitoring project was to develop the software tools and interpretation techniques 1) to isolate and interpret seismicchanges that have occurred in the field over time in terms of oil/gas/water changes in order to better understand the drainage of the field, and 2) to identify and locate bypassed pay. Two turbidite reservoirs of the South Timbalier 295 field, offshore Louisiana, Gulf of Mexico, provide contrasts in acoustic response that point to important lessons for 4D monitoring in other fields of the Gulf of Mexico. In the K-40reservoir, a "classic" updip water sweep pattern in the oil/water contact with tim...

ABSTRACT Electric vehicles are not penetrating the market as quickly as expected. This is due to limited driving range, time required to recharge a battery, and lack of charging infrastructure in most metropolitan cities. We propose a charge sharing network in which we use inductive power transfer to wirelessly exchange charge between vehicles. In our network, vehicles that have excess charge to share, can sell charge to vehicles needing charge to reach their destination. In this paper, we describe a game theoretic approach to offering incentives for electric vehicles to participate in the charge sharing network. We utilize Nash Bargaining theory to show that participation in the network can yield profits for the seller driving to their destination and that we can increase the number of cars reaching their destination without needing to stop for recharging.
