This paper presents an overview of the pressure drawdown test and the thermal stimulation test at the Mallik 2002 gas hydrate research well, conducted in February and March 2002. Pressure drawdown tests were conducted on methane hydrate, free gas, and water intervals, using Schlumberger's Modular Formation Dynamics Tester (MDT) wireline tool. The thermal stimulation test was designed to increase the in-situ temperature of a well-defined and constrained methane hydrate reservoir above the methane hydrate stability point, while maintaining constant pressure. The objectives of the production tests were to confirm the feasibility of production of natural gas from methane hydrate deposits by depressurization and thermal stimulation, and to collect sufficient data to determine relevant methane hydrate formation properties. The production tests were successful in that significant amounts of the in-situ dissociation properties, as well as other scientific measurements, were obtained.
