Not if you still needed cash flow to pay back loans that funded the whole deal to start with.

This field has been operational since the 1930's. I suspect that all the loans have been paid off.

I have always noted that as the oil price drops, the number of operational pumps drops.

There is a certain point where you break even on a well and price of oil determines it. When it reaches the point that the energy required to lift it exceeds the profits from it you shut it down. Let me add this is one of the worst things you can do with a well due to corrosion and paraffin but when it hits that point you flip the switch.
