It's certainly an area that again I think we have good solid regulations for in terms of managing the liability. Currently, the focus is on addressing more of the problem sites, those defined as older sites that are proximal to residences and such. Again, the industry and the regulator are working together to make sure that those sites are well managed and the wells are put to bed in a very effective manner. There are regulations that way.
From a technology standpoint, as I mentioned, it's looking at innovation that will provide a greater level of assurance of sealing the well off for perpetuity.
