which has remained at that figure ever since it was closed in, twenty-seven 

 months ago. Under this pressure (290 pounds) No. 7 produces oil 

 (23,000 barrels daily) as fast as the company can take care of it by sale 

 and storage, and for that reason Nos. 1 and 2 and 6 were shut down and 

 drilling, operations practically abandoned in other portions of the com- 

 pany's extensive holdings, in order that its entire resources could be de- 

 voted to taking care of the flood of oil which was pouring from No. 7, 

 although closed in as much as possible. For this reason wells Nos. 1 and 

 2 at Casiano were shut down on August 14, 1910, since they were pump- 

 ing wells, and have not been operated since, although No. 1 had produced 

 an average of 188 barrels daily, and No. 2 an average of 138 barrels. 

 Other wells in the Ebano district were also shut in when possible and 

 not opened again for several months. One of these was La Pez No. 1, 

 which, when shut in, was flowing an average of only 400 barrels daily, 

 but when opened again several months later, as stated by Mr. Doheny, 

 began flowing at the rate of 800 barrels daily, and has kept going at 

 the higher rate ever since, apparently making up for lost time. The 

 explanation of this curious freak on the part of Pez No. 1 is probably 

 due to the fact that, while it was shut in, the petroleum continued to 

 rise from below and enter the cavities and porous spaces from which it 

 had been partially exhausted during the previous years. 



Another remarkable well in the Ebano district is Laguna No. 2, which 

 began flowing at the rate of 500 barrels daily on November 7, 1906, and 

 in the five years and 23 days up to December 1, 1911, had put into tank- 

 age 750,240 barrels, an average daily output of 406 barrels for the entire 

 time, and it was still flowing about 450 barrels daily in December, 1911. 



The following table of production of the wells owned by the Mexican 

 Petroleum Company, Limited, of Delaware, brings the output of the 

 same up to April, 1913, and is supplementary to the table given fo 

 December, 1911 :
