I did have a sand play but it was supposed to replace Wisconsin white sand that was preferred for fracking. Turns out that the shipping costs are a big part of the cost and that closer local sand became prevalent. The Canadian outfit never raised enough money to make it into production before the price of crude fell sharply. Texas local sand put a big dent into premium Wisconsin white sales. Not a big enough moat and it turns out the local sand worked as well as the premium stuff or close enough so that lower costs won out.
