If you want to know who is on the sale or chopping block follow the money. ExxonMobil is investing in some sites and not others. Another clue is where maintenance budgets are being cut, those sites will be sold first. Cut maintenance budgets to milk the cash cow, appear very profitable, then sell for the highest price and it collapses on the buyer.
Baytown is increasing the maintenance budget and investing a lot in new projects. Baytown is the crown jewel for ExxonMobil and the investment shows it.
What is going on at other sites? Who is getting big projects? Who is having their maintenance budgets cut? Where are good people moving from and where to? Companies move their best employees from sites to be sold and move their worst employees to the sites to be sold.
