The exploration of offshore gas/oil has been moving to deepwater fields as big reservoirs have been found and technologies have improved. Presently, the most active areas in deepwater gas/oil field development are Africa and the GOM (Gulf of Mexico) in North America. There are many technological challenges in developing deepwater gas/oil fields such as: flow assurance, subsea systems, riser sys...

Abundant availability and potential for lower CO2 emissions are drivers for increased utilization of natural gas in automotive engines for transportation applications. However scarce refueling resources for on-road vehicles impose an infrastructure limited barrier on natural gas use in transportation. A novel ‘bimodal’ engine which can operate in a compressor mode has been developed that allows...

In this paper, an Ant Colony Optimization Algorithm (ACO) is proposed for operations of steady flow gas pipeline. The system is composed of compressing stations linked by pipe legs. The decisions variables are chosen to be the operating turbo compressor number and the discharge pressure for each compressing station. The objective function is the power consumed in the system by these stations. U...

Methane is the second most important greenhouse gas (GHG) after carbon dioxide. Amount of methane emission from energy sector is increasing day by day with various activities. In present work, various sources of methane emission from upstream, middle stream and downstream of oil & gas sectors are identified and categorised as per IPCC-2006 guidelines. Data were collected from various oil & gas ...

This paper proposes a method based on genetic algorithm (GA) for the security-constrained 11 optimal dispatch of integrated natural gas and electricity networks, considering operating scenarios 12 in both energy systems. The mathematical formulation of the optimization problem consists of a 13 multi-objective function which aims to minimize both cost of thermal generation (diesel and natural 14...

Ensuring the operational efficiency of hazardous production facilities throughout their entire service life becomes a formidable challenge associated with coordinating thorough monitoring such facilities, assessing exposure, mitigation and sustainability, taking measures to minimize prevent negative outcomes that can lead consequences, including human fatalities, injuries economic losses. At sa...

15. Supplementary Notes Supported by a grant from the U.S. Department of Transportation, University Transportation Centers program 16. Abstract Reducing fuel consumption and greenhouse gas emissions is becoming increasingly important in the United States, and new legislation can be expected in the near future that will affect trucks either directly or indirectly. This work is a qualitative exam...
