3 Louisiana only; its offshore production of oil and gas combined is estimated to represent close to 90 per- 

 cent of the total U.S. output. California accounts for the major part of the balance. In the years 1960 

 through 1964 its production of offshore oil ranged between 32,000,000 and 36,000,000 barrels; gas production 

 was relatively insignificant. The majority of its 2,000 offshore wells were slant drilled from shore or pier; 

 only about one-sixth of its production originates from offshore platforms. (These activities are not refiected 

 in the above table, since comparable data are not available.) There has been considerable drilling activity 

 over the years in Texas offshore areas, but to date results have been disappointing; offshore production of 

 oil in 1965 amounted to only 3,700 barrels and no gas production was reported. Drilling activity has been 

 underway off coastal areas of Washington and Oregon also, but without results thus far.
