This paper aims to explore various possibilities in the evolving global gas market by constructing game-theoretical models involving the major players: Russia and Qatar exporting gas to the Asia-Pacific and Europe, respectively. We explore a series of hypothetical scenarios based on competitive and collusive settings for the Asia-Pacific LNG market and based on Qatar’s export route to the European gas market. The scenarios that are examined are (1) Russia as the follower and Qatar as the leader in a Stackelberg game; (2) Russia and Qatar as Cournot competitors; (3) collaboration between Russia and Qatar as bilateral monopolies; (4) Qatar exporting gas to European borders; (5) Qatar exporting gas to the last transit country; and (6) Qatar transporting gas to the Turkish border under a multi-pricing scheme. Demand is estimated under each scenario to simulate the respective export volumes, prices and quantities, and profit in each scenario. By exploring these market interactions, we find that it is essential for Russia to strike a deal with Qatar in the Asian market and accelerate their gas production in order to compete as an LNG market leader. Russia is likely to benefit more if it can link with Qatar to act as a monopoly on their segmental demand curve. On the other hand, Qatar’s profit is expected to be higher under the scenario when Qatar sells all the gas to the last transit country as the sole demand point instead of passing through transit countries.
