The U.S. actually produced 10,044 million barrels per day in November 1970. It steadily declined to as low as 3,971 million barrels in September 2008, but has been rising since 2009 and recent peak production was 9,626 million barrels in April 2015.

It's also not necessarily conveniently located, with major crude oil producers having relatively small refining capacities and not necessarily located near states with significant refining capacities (*coughNorthDakotacough*).

Most likely. The U.S. Nuclear Targets list in v2.2 includes 8 refineries in California, 7 in Louisiana, and 13 in Texas. It also includes the Delaware refinery, 3 refineries in Illinois, 1 in Indiana, 1 in Kentucky, 2 in Kansas, 1 in Mississippi, 1 in Missouri, 4 in New Jersey, 2 in Ohio, 2 in Oklahoma, 2 in Pennsylvania, and 2 in Washington. In total, 50 refineries are on the target list, and some of the strikes may have included multiple refineries located in the same city. Another 18 refineries in Canada are also on the list.

There are also pipelines and they cross the whole of the U.S. and Canada.

North Dakota is served by 7 crude oil pipelines (Belle Fourche, Koch, Lakehead, Little Missouri, Madador, Magellan and Portal), and also 4 petroleum products pipelines, 2 natural gas liquid pipelines and 5 interstate natural gas pipelines.

Crude production tends to be more dispersed (and not necessarily near other valuable infrastructure), which makes it a less ideal target. Hitting at fuel supplies limits both civilian and military efficiency. Even if one considers the distillation of ethanol, that reduces the available food for the military and civilians, which is problematic once farm yields decline (due to the loss of modern fertilizers and pesticides, even if one ignores the drought) and the lean times start.

It would be impossible to hit every crude oil wellhead, and even more so with offshore oil rigs. But hitting the major refineries and clusters of refineries does make sense.
