THE CUBA REVIEW 21 



The Union Oil Company uses a Star Drill No. 30 and two standard machines of the Cali- 

 fornia type. Two iron tanks are installed at the mine, one with a (•a[)acity of 1,000 barrels 

 and another of 2,000 barrels, while still another is located on the railway at Minas with a 

 capacity of 1,000 barrels. A steam pump is used to force the oil through a two-inch i)ii)i! 14,000 

 feet in length, from the deposits at the mine to the station. The petroleum coming from 

 the Union Oil Company's wells is of superior quality, the analysis showing a content of 13% of 

 gasoline and 30% of illuminating oil. 



The quantity of petroleum sold from the month of December IDKi to June of this 

 year inclusive has been 1,740,051.78 gallons, as i)er the tabulation below:

This crude oil was first sold at 10c a gallon to different merchants who bought it by the 

 barrel, but after the pipe line was installed nearly all of the product was sold to the West India 

 Oil Refining Co. of Havana at the rate of r2c. per gallon. The Union Oil Company is the only 

 one of its class that has so far paid dividends to its stockholders. In the latter part of July they 

 began to open well No. 11. 



North of the Santiago well is the "Jorge" claim, where the Cuban Petroleum Company, 

 recently merged into the Compania Petrolera y Refinadora Cuban y Pan-Americana, is ex- 

 ploring for oil. The Jorge claim seems to be a very promising field in which to drill for oil in 

 that particular district. So far this company has sunk three wells, one of 840 feet, which at 

 first produced 25 barrels dailj^ but afterwards dropped to two barrels, although still yielding a 

 great quantity of gas. Well No. 2 was sunk to 1,100 fe?t, and oil was found at 540 fe?t, and the 

 well was abandoned. Well No. 3 produced 210 barrels the first day, but has since dwindled to 

 an average of 100 barrels a day. In the month of June, 1918, 3,385 barrels of oil were pro- 

 duced, with a large amount of gas, which is used for fuel for the tw^o furnaces of the com- 

 pany. All of its petroleum is bought by the West Indian Refining Companj^ of Havana. A 

 Star Drill No. 3 and a Standard are used by this company. 



On the 24th of July well No. 4 was started with a Star machine and drilled to a depth of 

 20 feet, but was soon abandoned. In another section of the Jorge property, the Republic 

 Petroleum Company drilled to a depth of 2,200 feet, finding petroleum at 995 feet. 



East of the Santiago property the Bacuranao Oil Company drilled a well to 1,009 feet, 

 which produced 12 barrels per hour during several days. This company has contracted with the
