| Abstract | The JOGMEC/NRCan/Aurora Mallik gas hydrate production tests were conducted using the depressurization method in April of 2007 and March of 2008. These tests represent the first and so far only
successful sustained production in the world of methane gas to surface from a gas hydrate reservoir by depressurization. A variety of data, such as wellhead/bottom-hole pressure and temperature, gas/water flow rates, and temperature along the casing
measured by distributed temperature sensing, were acquired during the tests. The flow rates of gas and water from the reservoir sand face during the tests were estimated by comprehensive analysis of these data. Diverse history-matching simulation was
then conducted to reproduce these estimated flow rates, using the numerical simulator MH21-HYDRES coded especially for gas hydrate reservoirs. This series of history-matching simulation studies quantitatively clarified the mechanisms of methane
hydrate dissociation and production, as well as what had happened in the reservoir during the production tests. This paper describes the procedures and results of a series of these studies, including the analyses of production-test data, numerical
modelling and history-matching simulation, which will provide beneficial insights into the mechanisms of methane hydrate dissociation and production for future exploration and development planning for gas hydrate resources. |
