About Crimson and the Crimson Properties

Crimson has varying working interests in 18 producing wells with an average production of 120 boepd. The wells and associated lands are situated in the West Central Alberta Deep Basin, the Peace River Arch and Northern Alberta.

West Central Alberta

Chambers/Ferrier (Deep Basin)

Crimson has a working interest (WI) in 3 producing gas wells and 6 SI/Standing wells in the Chambers/Ferrier Area. The producing wells in section 1-41-10W5M, (3-01 and 9-01) are operated by TAQA North and produce approximately 4 boepd net to Crimson (6.625% WI). An offsetting well in 8-02 is currently shut-in and is a candidate for a possible workover/recompletion.

The Ferrier 14-06-41-10W5M discovery well was drilled by Husky and Crimson in late 2008 and completed by Crimson in late 2009/early 2010. The well was tested in three zones at a combined rate of approximately 1500 mcf per day and 35bbls/mmcf per day of NGL’s and condensate. The well was put on production to the Keyera operated Strachan Deep Cut Gas Plant in October 2011. March 2012 production from the well averaged approximately 80 boepd. Crimson has a 63.1455% WI (APO) in the well and in the offsetting 6-05 wellbore.

Crimson also has varying working interests (8.28-15.6%) in 3 standing wells in the Chambers area (41-11W5M).

Pembina/Violet Grove

In 2011 Crimson acquired a 100% working interest in three sections of land with seismically identified Nisku oil potential from a major oil company in the Violet Grove area of west central Alberta. There are two drilling locations identified from 3D seismic interpretation that were licenced by the previous owner. In 2011 Crimson also re-entered an abandoned well bore in 9-34-47-08 W5M and re-completed the well in the Mannville which tested very low gas rates indicating a tight zone.

RockBridge holds a 50% WI in the 9-34 well, and has the right, subject to further financing, to farm-in on a high impact, light oil project paying 25% of the well costs to earn a 15% WI in the three sections of land.

Harmattan

Crimson has a 35% WI in a Rundle Oil Well located in LSD 14-08-32-02W5M. The well is operated by TAQA North and produces 15-20 boepd (5-7 boepd Crimson WI). Horizontal well potential has been identified on Crimson lands offsetting the 14-08 well. Crimson (50% WI) acquired an additional section of land offsetting the 14-08 well at the October 13, 2010, Alberta Crown Sale.

Kaybob

Crimson participated in the drilling of a deep Duvernay Shale oil/gas test in the Kaybob area (14-15-61-21 W5M). The well encountered 30 metres of Duvernay zone and was subsequently plugged back; intermediate casing set; and the rig released. The operator’s future plans are to re-enter the well and drill a horizontal section in the Duvernay. After drilling the test well Crimson farmed out its working interest in the well and surrounding 10 sections of land for Crimson’s share of drilling costs and gross overriding royalties (GORR) ranging from 0.7% to 1.18%.

Giroux

Crimson converted its 25% WI to a 12.5% GORR in a standing Montney well at 6-08-66-20 W5M. The well was fracture stimulated by the operator and tested oil, water and gas. The well has been tied into a nearby gas gathering system and averaged 4.5 boepd in March 2012.

Peace River Arch

Wapiti

Crimson has a gross overriding royalty interest in 9 producing gas wells and a working interest in 3 other producing wells in the Steep Creek and Wapiti area, near Grande Prairie in Northwestern Alberta. Crimson’s March 2012 production in Wapiti averaged 20 boepd.

Knopcik

RockBridge farmed in on Crimson and re-tested a standing/shut-in Nikanassin gas well at 5-10-74-11 W6M which resulted in proving up gas potential in the well/zone and obtaining an extension to the primary term of the petroleum and natural gas lease. Future plans are to re-stimulate the Nikannassin; re-complete the uphole Dunvegan zone; and commingle production from both zones. Crimson and RockBridge each hold a 50% WI in the well.

Northern Alberta

Little Horse/Randell

Crimson has 3.375% WI in 2 producing oil wells operated by Penn West Petroleum in the Little Horse/Randell area of Alberta.

Cherpeta/Francis

Crimson has a 40.5% WI in 2 producing wells operated by Husky in the Cherpeta/Francis area of Northeastern Alberta. Crimson’s WI production in March 2012 was approximately 50 boepd.

Reference to BOE means barrels of oil equivalent and is derived by converting gas to oil at the ratio of six thousand cubic feet (mcf) of gas to one barrel (bbl) of oil. 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 top and does not represent a value equivalency at the wellhead. References to BOEPD means barrels of oil equivalent per day.
