Figures are unitary count (#) not seasonally adjusted (NSA). The series start in January 2000.

The series reside in the historical catalog (United States » Energy » Baker Hughes » North American Rotary Rig Count » Weekly) and are:

• BHAROW.IUSA_OFSH  = Active rotary rigs: Gas and oil, (#, NSA) - for U.S. Offshore
• BHARW.IUSA_GOME   = Gas and oil - for U.S. Gulf of Mexico
• BHARGSW.IUSA_GOME = Gas
• BHAROLW.IUSA_GOME = Oil

Because a catalog locations are subject to change, the upper-right search box on DataBuffet.com provides a "find in catalog" mode that accepts a mnemonic.

About the dataset:

• The "U.S. Gulf of Mexico" count includes only the four Gulf states (Texas, Louisiana, Mississippi, Alabama). Although it borders the Gulf, Florida's production (if any) is classified as Atlantic.
• The "U.S. offshore" count is more inclusive, but is dominated by the Gulf of Mexico.
