Chevron has several moving pieces occurring simultaneously. You are exactly right about Briar Park. That facility will not be relocated downtown under any scenario. Similarly, Chevron owns and occupies two office buildings on the old Texaco facility in Bellaire. They are currently demolishing several old lab buildings on that site that will free up some land that could be repurposed later. I don't anticipate them leaving this facility any time soon. ChevronPhillips Chemical is headquartered in The Woodlands and will always remain separated from the parent company because its a JV with Phillips 66. They are expanding rapidly and will need additional space (very apt to stay in The Woodlands area). They have already closed the Sugar Land office (old Unocal building) and moved those employees downtown. In addition to 1400 Smith and 1500 Louisiana, they also currently lease about 20 floors in the Cullen Center (Continental building) and 20 floors in Allen Center. The employees in these leased offices will occupy much of the new tower. Additionally, they are constantly transferring employees and business units from San Ramon to Houston. Also, they are continuing to hire at high rates to accommodate their expansion aspirations. For example, they recently added several hundred new employees in Houston for their Kittimat project with Apache, almost overnight. The rate of new hires will ultimately slow; but it shows no signs of stopping, yet. Oil companies are currently facing an interesting dilemma. Their queues of attractive projects and opportunities are huge and the need for the services they provide are growing globally. It takes enormous capital investment to accommodate this growth. Yet Wall Street has been pressuring these companies to show more discipline in their capital budgeting. While this makes sense from a short-term stock valuation perspective, it could lead to longer-term energy shortages. How might this come into play here? When capital is perceived to be tight, the capital associated with office buildings struggles to compete with projects that more directly meet the organization's objectives and provide the organization with better returns. This will force companies to consider lower cost alternatives.
