The Economics of Petroleum Exploration and Development in Viet Nam By H. Luong Lien A thesis submitted to The University of New South Wales in partial fulfilment of the requirements for the Degree of Master of Engineering December, 1998 School of Petroleum Engineering The University of New South Wales, Sydney, NSW, AUSTRALIA ACKNOWLEDGEMENTS My sincerest thanks go to Mr. Guy Allinson and Associated Professor Sheik Rahman from the School of Petroleum Engineering, University of New South Wales, for their supervision and supports. Without their encouragement, support, flexibility and guidance, this thesis could never have become reality. My special thanks to Mr. Guy Allinson for making time for me despite his busy schedules. Guy gave me my first break by agreeing to supervise my research and giving me directions. Guy also gave me the opportunity to work at Petroconsultants and Cairn Energy. I thank him for his invaluable guidance and feedback, and his patient reading of my write-ups. I am also indebted to Petroconsultants Australasia in Sydney for permission to use their library and other data belong to the company. I wish to thank Mark Elliston from Petroconsultants Australasia for his advises and helps in building the cashflow models. Many thanks to Jenny, Rebecca and Kim from Petroconsultants Australasia for their assistance in helping me finding the data and information incorporated in this thesis. I would like to thank all the people that I met in PetroVietnam last year for their willingness to help me understand various aspects of the petroleum industry in Viet Nam. I thank my parents for their love and supports through the years, and for encouraging me to stay in Australia two more years to take this Master research course. They are my motivation when I lost interests in studying. I thank my Khanh for his love and patience and for always being there for me through good times and bad. Warmest thanks to my house-mates Uyen, Binh, Due, Tuan for their friendship. They were my second family when I was miles away from home. ABSTRACT When international oil companies make investment decisions to explore for and develop petroleum resources in a particular country, they need to examine many aspects of that country to assess the opportunities and risks associated with the new market. The main objective of this thesis is to provide a detailed assessment of various factors affecting the economics of petroleum exploration and development in Viet Nam from the investors’ point of view. The thesis includes information and analyses on geography, business environment, infrastructure, and the energy market in Viet Nam. The country’s petroleum exploration performance and field developments are also discussed in detail. Exploration and development costs are estimated for different areas of Viet Nam. The structure and components of Vietnamese fiscal regime are examined and analysed to gain a better understanding of the current forms of petroleum arrangement in Viet Nam. Most importantly, the economic and sensitivity analyses are carried out to demonstrate the profitability of exploring for and developing representative oil and gas discoveries in different physical and geological conditions. In addition, fiscal analyses are conducted to assess the economic effects of the government take on marginal projects.
