Tourmaline Announces Start-Up of Two Gas Facilities and Record Production Levels

CALGARY, AB--(Marketwired - October 20, 2014) - Tourmaline Oil Corp. (TOU.TO) ("Tourmaline" or the "Company") is pleased to announce that two new gas facilities, the Musreau Alberta and Doe B.C. 50 mmcfpd plant expansions, were successfully commissioned last week. With the start up of the two projects, daily production has reached a record 136,000 boepd. The Doe B.C. facility start-up has allowed for a 20 mmcfpd net production increase thus far, with a further 30 mmcfpd to be realized in mid-November with the start-up of the associated Sunrise 15-34 compression expansion. Musreau and Doe are the second and third of the five new facilities coming on-stream during the fourth quarter of 2014. The new Spirit River AB gas plant start-up in November and the Wild River AB plant expansion in December will result in the planned 2014 production exit volumes of 150,000 - 155,000 boepd or greater. The Company is currently anticipating average production of 164,500 boepd for 2015.

Start-up of all five Tourmaline operated 2H 2014 facility projects were delayed approximately six weeks from the original on-stream dates established during the first quarter of 2014. These delays will reduce the full year 2014 average production volume estimate by approximately 5,500 boepd. Ongoing, unplanned mainline pipeline maintenance on the TCPL, Spectra and Alliance systems and ongoing TCPL activities on the Robb lateral have resulted in an incremental 3,000 boepd of unscheduled downtime for the year thus far. Consequently, Tourmaline is reducing the full year average production estimate to 115,000 boepd from 120,000 boepd. The revised estimate represents 54% year-over-year growth in average annual production.

Third quarter 2014 production was reduced by the aforementioned mainline pipeline systems maintenance, the TCPL Robb lateral integrity investigation (2,000 boepd), the loss of liquid volumes at the third party Saturn deep-cut facility due to an equipment failure in September (4,000 boepd reduction), and unscheduled maintenance at the third-party Musreau AB facility where Tourmaline delivers excess gas volumes (1,500 boepd). As a result, third quarter 2014 production averaged approximately 108,000 boepd; fourth quarter 2014 production is expected to average between 135,000 and 140,000 boepd. Average production for the first nine months of 2014 is approximately 107,000 boepd, representing a 51% increase over last year's average production for the same period.

Tourmaline continues to operate 20 drilling rigs and has rig released 102 new wells since spring break-up (91 operated, 11 outside operated). The Company is now expecting to drill and complete 195 wells between mid-May 2014 and March 2015, with essentially all of these wells on-stream by the second quarter of 2015.

Tourmaline will issue Q3 results as well as an updated financial and operational forecast after the market closes on November 5, 2014.

Additional Reader Advisories

Boe Conversions

Boes may be misleading, particularly if used in isolation. A boe conversion ratio of 6 mcf:1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. As the value ratio between natural gas and crude oil based on the current prices of natural gas and crude oil is significantly different from the energy equivalency of 6:1, utilizing a 6:1 conversion basis may be misleading as an indication of value.
