COP CIO has announced that he is "all in" with the cloud, that should start the downsizing of Bartlesville IT. Phillips 66 is doing the same thing and their layoffs are to resume Jan 1 2019 in Bartlesville/Worldwide.
I am guessing the next two years will dismantle Bartlesville. Leaving some of the Finance and HR people in Bartlesville. But that can easily be moved to Houston, for both companys.
