Thank you, Mr. Chair. And I thank Mr. Trost for his comments about being a bit of a natural gas person. I remember one time he told me about being a bit of an accountant, so right back at you.
Mr. Dunn, I'd like to start with you. You were talking about the fluids used in the fracking and about some of these “greener” fluids, if you will. I would just like to ask you a little bit about that. In one of the environment commissioner's reports, he talks about the analysis it takes to get these chemicals approved and reviewed.
How much development have you seen in these, I guess you call them greener chemicals, in the last five to ten years, and have there been delays in getting some of these licensed for use by the firms?
