The relative importance of the States in the Union is shown in 

 the accompanying table, which gives the marketed production for the 

 year 1914. In the case of two of the States at least, the marketed 

 production is below the estimated j^roduction, the discrepancy being 

 accounted for by oil put in storage. The actual production of Cali- 

 fornia was probably around 103,000,000 barrels, with possibly 

 7,000,000 barrels " shut in," which might have been produced. The 

 estimated production of Oklahoma was 98,000,000 barrels.

FACTORS GOVERNING THE PRODUCTION OF PETROLEUIM. 

 Before entering into a discussion of the probable future production 

 of petroleum in the United States, it will be well to outline the various 

 factors which govern this production. These factors may be divided 

 into two groups, natural and artificial.
