I don’t think it’s likely that US black ops hit Saudi oil on purpose, even if MBS was in on it. That seems like InfoWars level conspiracy bullshit.
Far more likely (relatively, but still very low probability) are the Saudis orchestrating an attack in order to prevent Iranian sanctions relief/JCPOA 2.0 and to drag the US into armed conflict with Iran. This fits with MBS prior MO (see what happened with Qatar in 2017) and the timing of the attack just as we hear Trump Admin and Iran are negotiating on sanctions is suspect. I don’t buy the “launching an attack gives us negotiation leverage” bullshit—that might be some Taliban-level logic but the Iranians are smarter.
Losing half of your oil production for a few weeks is nothing compared to what they’ll get back in terms of military aid, contracts and fees for upgrading bases, defenses and housing more US troops for the next 20-30 years.
