On March 14, 2007 OAO NOVATEK announced that DeGolyer and MacNaughton (D&M) have completed their comprehensive reserve appraisals of the Company’s oil and gas reserves as of 31 December 2006.

Total proved reserves of natural gas increased from 641 billion cubic meters (bcm) in 2005 to 651 bcm in 2006, an increase of 39 bcm, inclusive of 2006 production. Of significant importance was the growth in proved producing reserves of 929 million boe (not including production), or 35,4%, over 2005.  In 2006, on a barrel of oil equivalent basis, NOVATEK replaced 144 percent of its production volumes from the appraised fields, or 190 percent over a three-year period (2004 to 2006), and at year-end 2006, the Company’s reserve to production ratio (or R/P ratio) is 23 years.
