The problem here is that much of the data before 1987 combines oil and gas rigs, and some of the counts are much higher than the current total of oil rigs alone. The EIAâs historical rig data shows a high of 4,521 rigs in 1981. Baker Hughes showed a record rig count of 4,530 recorded on Dec. 28, 1981.
