  • [James Vernon] also expects demand for high quality barite to decrease as shale plays do not require barite as heavy as conventional well bores, because the density is not as high when compared with conventional well bores, adding that the higher grade barite of 4.2 SG or above is "a little bit scarcer than it used to be." "There's nothing out there right now that [indicates] you're going to see any radical change. If some of these [countries like China] go on a binge buying spree - that could affect [prices] - but I don't think it's going to be big swings - probably curve swings," he said.

    "It has been too expensive to export because of where its [barite] located, therefore it probably wouldn't impact the export barite market. But it's really hard to get to that information - China's not very good at exposing what their reserve picture is - either for minerals or natural gas," he told IM.
