Aquifers refer to water not oil. The water drawn for human use comes from shallow aquifers.

Oil comes from thousands of feet underground in most places, including TX.

There are shallow oil wells but they're in Alberta and inland CA.

Many aquifers in coastal Texas are what they call "house of cards clay". The clay plates are stacked on edge with the water in between. When the water is drained, the clay plates fall over.

And the ground sinks. This is a big reason why surface water is used instead of aquifers for the cities. There is plenty of rain to feed the lakes. The sediment layers are very deep, with rock layers being hundreds of feet down. This is true for most of the Gulf Coast except for Florida. Much of Florida is an old coral reef which is why sinkholes are such a problem.
