Let's look at the Viking here is a table from March 2015 issued by TD, they undertook a detailed analysis of all the Viking sub areas:
Penn West core area is Dodsland, Dodsland is one the areas with the lowest breakeven price and quickest payout ratio. PennWest is by far the largest producer in that area, thus the average results for the area are influenced highly by Penn West assets and performance in this part of the Viking play:
Does the Dodsland results strike you as a company under preforming in its core area? Talk is cheap, but the data speaks for itself. I would caution against taking what Eric says at face value, he has often claimed certain companies operations and basins were top notch (Westfire, Legacy..etc) and generally he has a bias against ex-Trusts, he has been singing the same tune about Penn West having bad execution for years (and they did for many years prior to the new team) however he seems to be stuck in an outdated view about how Penn West core assets are preforming now.
