There are around 3.5 million oil rigs, though some are not entirely used to drill for oil and most is on land. Many rigs are used to drill for water and geothermal heat. Usage of geothermal heating is common in Europe, and mobile oil rigs are used.

Oakley oil rigs are oil rigs and Oakley sunglasses are sunglasses.
There are almost 4,000 oil rigs in the U.S. 79 are deep water wells.
In the United States, the oil rigs that operate offshore are typically too far away to see. There are many work over or drilling rigs in the Texas, Oklahoma and California but they may only be active in one place for a short time. I have flown over the Gulf Coast, and seen from the air what appears to be oil rigs, but they may have been producing platforms. It is far easier to see the pumping units, (pumpjacks) as they are very common in Bakersfield, California.
Many thousands.
