This paper describes and analyses the natural gas industry in Trinidad and Tobago, with particular emphasis on markets, gas pricing and legal issues, and concludes with the future outlook for the Trinidad and Tobago gas industry. Formerly seen as a useless by-product in the search for oil, natural gas is now seen as the fuel of the future. While oil maintains the backbone of the Trinidad and Tobago economy, gas has assumed an important role over the last two decades. Natural gas is now the principal feedstock used in electricity generation and provides the base for downstream petrochemical industries. Over the next decade, natural gas will supersede petroleum as the driving force behind the Trinidad and Tobago economy.
