The symposiums are free to attend and the invitation list is drawn from council membership and the host's own network, which is how a room at BASF Freeport ends up containing the people who run the site rather than the people who sell to it. The working sessions at Visa are smaller and closed, and that is a working decision rather than a posture. An executive will describe what went wrong in a deployment when the room is not being recorded and will not do it from a conference stage, and the Texas A&M symposium's most useful finding came out of exactly that kind of exchange.
Membership of one of the six councils is how organisations get into those rooms, and it is also how the agenda gets set, because each programme is built from what the councils are working through at the time.
The public conferences need nothing but a registration. The next one where consortium people are on the programme is Digitalization in Oil & Gas in Houston on 10 September 2026, and the hour either side of a session is usually the easiest time to find them.
