AbstractThe Mallik 2007-2008 Gas Hydrate Production Research Well Program was conducted at the Mallik site in Canada's Mackenzie Delta, Northwest Territories over two successive winters. Year 1 (winter 2007) operations are described in another paper in this volume. In year 2 (winter 2008), the Mallik 2L-38 and Mallik 3L-38 wells were reopened following their suspension at the end of the previous year's field campaign. Mallik 2L-38 was subsequently recompleted for extended production testing, while Mallik 3L-38 was equipped as a produced-water disposal well. Operational activities during the winter 2008 campaign were conducted during a 77-day period from January 16 through April 3, 2008, and included ice-road and site construction, mobilization of camp facilities and service rig, well re-entry, well testing, well abandonment, and demobilization.
The Mallik 2L-38 well was perforated (in 2007) over a 12 m interval from 1093 to 1105 m, just above the estimated base of gas hydrate stability at the Mallik site. Production testing was conducted in three stages, under three different bottom-hole pressure (BHP) targets. Continuous gas production from the Mallik gas hydrate reservoir was achieved during a 6-day period from March 10 to 16, 2008. At the conclusion of the campaign, all of the Mallik wells that had been drilled during the course of four gas hydrate research programs (in 1998, 2002, 2007, and 2008) were legally abandoned.
