DRILLED WELLS.

The chief feature of these figures is their insignificance, the 

 largest annual production, ever on record, being 1,258 barrels, that 

 is to say, the Yenangyat oil field produces as much in one year as the 

 pit wells of the Yenangyoung oil field produce in about 4 days. 



Section II. — The drilled wells. 



Since the summer of 1891 a few wells have been drilled in the 

 Yenangyat oil field, but it cannot be said that they have proved a 

 success. However, we must reserve our judgment regarding the im- 

 portance of the Yenangyat oil field, till a few more test wells have 

 been constructed. There are at present 7 wells, which are all situ- 

 ated in the Yenangyoung ravine. Of these 6 are productive ; one 

 did not yield oil and was abandoned. The wells are generally much 

 deeper than those of Yenangyoung, without however the object of 

 a good production having been attained. 



Like the pit wells, the drilled wells are very poor, even much 

 more so than the former. I have no accurate data regarding 

 the individual daily production of these wells, but it is certain that it 

 never could have exceeded 210 gallons per day ; most probably it 

 ranged from 126 to 168 gallons. If compared with the wells of the 

 Yenangyoung oil field, where a well yielding 500 gallons is considered 

 to be a poor well, the above production must appear very insigni- 

 ficant, and can hardly be considered as a great inducement to further 

 efforts. 



The following table will show the monthly production, as recorded 

 during the last two years : —
