Résumé(Sommaire disponible en anglais seulement)
The Mallik L-38 lease area in the outer Mackenzie Delta has been the site of three historical gas hydrate drilling programs, Mallik 2L-38 conducted in 1998, and Mallik 3L/4L/5L-38 conducted in 2002 and the Mallik gas hydrate production program conducted in the winters of 2007 and 2008. The 1998 and 2002 programs utilized conventional drilling sumps to dispose of drill cuttings and fluids. Of note, an additional drill sump constructed in the winter of 1973 is also at the Mallik site. This sump, which was part of the Mallik L-38 discovery well, was constructed by Imperial Oil Ltd. and is not part of the undertakings described in this report. In 1998 the Japan National Oil Corporation (JNOC) and the Geological Survey of Canada (GSC), Natural Resources Canada (NRCan) collaborated to complete a gas hydrate research program (Dallimore et al. 1999). With JAPEX Canada Ltd. (JAPEX) acting as the operator, the JAPEX/JNOC/GSC Mallik 2L-38 well was drilled and a drilling waste disposal sump, approximately 45 m x 50 m in size was constructed on the lease. This sump is referred as the Mallik 2L-38 Sump.
In 2002, a seven-party participant group also led by JNOC and GSC, with JAPEX as the operator (Dallimore and Collett 2005), drilled the JAPEX/JNOC/GSC et al. Mallik 3L-38, 4L-38 and 5L-38 wells. JAPEX Canada Ltd. acted as the operator for this program, constructing a drill sump, approximately 50 m x 55 m in size, was constructed to dispose of the drilling waste generated during drilling of the three wells. This sump is referred as the Mallik 3L/4L/5L-38 Sump.
In the winters of 2007 and 2008 a third gas hydrate research program at the Mallik site was led by Japan Oil, Gas and Metals National Corporation (JOGMEC), NRCan and the Aurora Research Institute (ARI) called the JOGMEC/NRCan/ARI Mallik 2007-2008 Gas Hydrate Production Research Well Program. ARI acted as the operator of this program with the Japan Oil Gas and Metals National Corporation and Natural Resources Canada as participants. This program re-entered the 2L-38 and 3L-38 wells without construction of the sumps. All drilling waste material was removed from site and disposed of at an approved facility (Dallimore et al, 2013). As a condition of Water Board License No. N7L1-1817, ARI was required to undertake a 7-year monitoring program at the Mallik 2L-38 and Mallik 3L/4L/5L-38 sumps.
The information provided in the annual sump monitoring submissions to the Water Board satisfies the conditions assumed by ARI under Part H of the Northwest Territories Water Board License No. N7L1- 1817: Conditions Applying to Abandonment and Restoration, specifically section H 2 which states 'The Licensee shall monitor the existing drilling Waste Sumps 2L-38 and 3L/4L/5L- 38 after closure for a period of at least seven (7) years in accordance with the Northwest Territories Water board Publication 'Protocol for the Monitoring of Drilling-Waste Disposal Sumps, October, 2006'.
This summary report is provided to the Water Board on behalf of ARI as a courtesy to assemble all of the pertinent monitoring observations during this period.
Résumé(Résumé en langage clair et simple, non publié)
La zone de concession minière Mallik L-38, aux abords du delta du Mackenzie, a été le site de trois programmes de forage d'hydrate de gaz. Le permis de l'Office des eaux de 2007-2008 avait pour condition que l'Institut de recherche Aurora (l'exploitant du programme) entreprenne un programme de surveillance de sept années des sites de forage de Mallik. Les travaux ont été menés par KAVIK-Stantec et la CGC a assuré la surveillance scientifique. Le présent rapport, présenté à l'Office des eaux des Territoires du Nord Ouest en juin 2015, résume les données recueillies durant le programme de surveillance de sept années. Il est maintenant publié sous forme de rapport public de la CGC pour rendre l'information plus accessible au public.
