Hi Bearcat,
There is a huge amount of alot of siesmic data available for the Turner Valley area, and more is being shot all the time. You are correct in that the regional trend is north-west to south-east. Also, the structures (pools) tend to be narrow and elongated from one to 4 or 5 miles long on average, but they can also be subtle and in the shape of small domes like BEA's crossfield hit down in section 13, tp 19 r2 W5, or smaller flexures on the limbs of large folds. Many structures are parallel, due to 'harmonic' folding, and thrust fault related folding. In addition, these structures must have a regional plunge and closure to trap gas &/or oil. Often there are also en echelon structures. This is why siesmic is performed-to find and identify these structures. Unfortunately, sometimes they are breached and there is no oil or gas in them and sometimes they are full of water. You have to drill to find out. Nobody will bid big money at a land sale, or drill a well, without already having a siesmic 'picture' of the sub-surface in hand. I am sure every player in the Turner Valley area has there own siesmic data base. I could post a rendering/cartoon of Mississipian and Devonian time structures, but then somebody from Calgary would have to kill me.
