THE CUBA REVIEW 



About two kilometers west of Caimito de Guayabal near the boundary of the province of 

 Havana, Mr. Shaler WilHams has drilled several wells, one more than 1,570 feet, which yields 

 oil and gas in small quantities. 



The Antillian Corporation, owner of two large grants of petroleum in the Province of 

 Havana, the Georgina and Antillana, east of the capital, between Bejucal and Guines, in the 

 Candela Hills, has opened a well of 3,006 feet with no results. This well will be extended to a 

 depth of 4,000 feet. The company purposes drilling another well in the Antillana grant, near 

 the town of Managua, 24 kilometers from Havana. This well will be svmk to a depth of 3,000 

 feet. 



There are other companies who have started exploration in search of petroleum, mostly 

 in the Province of Havana, with negative results so far. Some of them have suspended work 

 owing to lack of capital, others, through inefficiency of machinery. 



PRODUCING COMPANIES.— We will now consider the work realized by the three 

 petroleum companies that have obtained results. 



The Union Oil Company since 1914 has been successfully exploiting the Santiago claim 

 near Bacuranao, some ten miles east of Havana. During the last two years this company has 

 drilled ten wells with varying results. One of these reached a depth of 700 feet, producing 

 three or four barrels of superior petroleum per day, but this was afterwards abandoned. Nos.

1 and 3 were abandoned at a depth of a few feet because rock was encountered too dif- 

 ficult to penetrate. No. 4 at a depth of 560 feet produced 10 to 15 barrels daily. No. 5 at 

 1,016 feet has produced up to 400 barrels daily. No. 6 was abandoned at 1,912 feet without 

 showing any oil. No. 7 yielded petroleum at 1,000 feet and was abandoned. No. S was drilled 

 to 1,009 feet and produces quite a good supply of oil. No. 9 arrived at 1,009 feet and is pro- 

 ducing oil, while No. 10, sunk to a depth of 1,012 feet, produced a little oil at 272 and 1,000 ft. 

 The ten wells have been drilled in a restricted area of 300x300 meters, all within the perimeter 

 of the Santiago well.
