transportation to East Coast markets by ocean tankers, and to 

 Midwest markets by barge via the Intracoastal Canal and 

 Mississippi River, and by pipeline (U.S. Department of the 

 Interior, 1957). 



In Louisiana during the same year, there were 16 refineries 

 with a total daily operating capacity of 643,500 barrels. Eleven 

 of these refineries (with a capacity of 574,175 barrels) were 

 in the Gulf Coast area (2 were in Lake Charles, the rest were in 

 the New Orleans-Baton Rouge corridor), because of the transpor- 

 tation advantages (U.S. Department of the Interior, 1957). 



Increasing reserves, both onshore and offshore, encouraged 

 continued expansion of refining capacity so that by 1976 the 

 capacity of Texas refineries has grown to 3,966,330 barrels per 

 day (although the number of plants has decreased to 46), and 

 Louisiana's refining capacity has grown to 1,753,095 barrels 

 per day at 19 plants (Oil and Gas Journal, March 29, 1976). 



While OCS production of crude oil has represented a 

 significant proportion of total production in Louisiana 

 (almost 527. in 1973), it has accounted for less than 1% 

 of Texas production (Table 1.6). Therefore, it can be 

 concluded that OCS oroduction has been an imDortant factor 

 in stimulating expansion of Louisiana refinery capacity, 

 but that the Texas expansion has been largely a result of 

 onshore production. 



The intrastate and interstate refinery receipts 

 for Texas and Louisiana by Petroleum Administration for 

 Defense (PAD) districts are shovm in Table 1.7 and Figure 1.13.
