Economic evaluation of gas to liquids (GTL) product transportation through the Trans Alaska Pipeline Systems (TAPS)Ejiofor, Nkemakonam (2003-05)The Alaska North Slope is a potential candidate for the Gas to Liquid (GTL) technology. With over 38 Tcf of natural gas reserves stranded on the Alaska North Slope, the GTL technology is considered as a possible method of harnessing the abundant resources. GTL fuels are environmentally friendly (sulfur free) with better ignition and burning properties than conventional petroleum products from crude oil. Evaluating the options of transporting GTL products through the existing Trans Alaska Pipeline System (TAPS) together with crude oil either as a blend of crude oil and GTL (commingled) or as alternate slugs of each product (batching) is the main focus of this study. Economic evaluation using Rate of Return analysis to identify the most favorable mode of transportation of the GTL products was performed. Batching, using the modem tracking and sensor techniques was found to be the most economic method yielding the highest return on investment.
