Akter F, Huque M M, Rahman L. (2016). Bibiyana-Dhanua 137 km x 36 Gas Transmission Line: A Simulation Study and Economic Analysis. International Conference on Petroleum Engineering (ICPE). Bangladesh University of Engineering & Technology (BUET), Bangladesh.


Most of the gas fields in Bangladesh are located in the eastern part of the country. The backbone of gas transmission network started from the Sylhet region to Ashuganj main hub and then to the capital city Dhaka, greater Chittagong region and some western regions like Bogra, Tangail, Rahshahi. During the length, the downstream locations face low pressure and flow problem. In 2014, to overcome low pressure and inadequate flow problem, Gas Transmission Company Limited (GTCL), Bangladesh has set up the largest transmission pipeline Bibiyana- Dhanua (B-D) 137km x 36’’ parallel to Bibiyana-Muchai-Ashuganj-Dhanua transmission pipeline. This parallel line will facilitate gas transmission directly from greater Sylhet region to the western part of Bangladesh. Bibiyana is the largest gas field in Bangladesh operated by Chevron Bangladesh with 2P reserve of 5.754 TCF as reported by Petrobangla and currently producing 1200 MMscfd gas. GTCL has implemented the Bibiyana-Dhanua Gas Pipeline project with an aim of supplying additional gas to greater Dhaka and western regions and thereby, lone dependency on Ashuganj hub will be reduced. Considering present gas reserve in Bangladesh, the parallel Bibiyana- Dhanua 137km x 36’’ pipeline is solely dependent on the reserve of the Bibiyana gas field. B-D line has been designed to handle at least 650 MMscfd of gas. But currently this pipeline is transmitting around 200-300 MMscfd of gas only. This study focused on a simulation study to find out the maximum gas handling capacity of 36” pipeline for a given upstream and downstream pressure restriction. Based on present gas production from Bibiyana gas field, this study also simulates the transmission capability for the existing gas supply situation and finds the optimum transmission pipeline size. This study also ends up with an economic analysis to calculate the Net Present Value (NPV) and Benefit Cost Ratio (BCR) of the B-D line project.
