OCS activity in federal areas of jurisdiction, including 

 tracts and acres offered and leased, bonus dollars paid, 

 tracts and platforms currently active, and number of fields 

 was summarized (Table 1.2). Louisiana's OCS has been the 

 most significant, while the Mississippi-Alabama-Florida 

 (MAFLA) area has been the least significant, with no fields 

 discovered there thus far (Table 1.2). 



Louisiana's significance is better illustrated in Table 

 1.3, which shows the relative importance of production on the 

 Gulf of Mexico OCS compared to total U.S. OCS production and 

 to total offshore and onshore production in the U.S. 

 Louisiana has accounted for 99.5 percent of the oil, and 

 95.6 percent of the gas produced on the Gulf OCS since 

 1953 (Table 1.3). Of the total U.S. OCS production since 

 1953, the Gulf of Mexico has produced 96.4 percent of the 

 oil and 97 percent of the gas. Of the total U.S. oil and 

 gas production for the years 1953 through 1975, the Gulf 

 OCS has produced 5.70 percent of the oil and 7.57 percent 

 of the gas . 



The total production of oil and gas from the Gulf of 

 Mexico OCS is tabulated by year and by state (Table 1.4). 

 Also included in Table 1.4 is the OCS production of sulfur, 

 and salt (which began in 1960 off the coast of Louisiana) . 

 Thus far, none of these minerals has been produced offshore 

 from Mississippi, Alabama, or Florida. (There were, however, oil 

 and gas leases sold in 1959 for the Florida Gulf OCS and in 

 1973 and 1976 for Mississippi, Alabama and Florida, but no 

 production has resulted from these leases up to 1977.)
