Well carried down in " Pocket " 9 " 575 = 792 



Size of hole 5^-" ; drilled wet ; cased with 3^" casing to shut off the 

 water. Seed bag on casing below 2d S. S. say at about 445'. 



A " mud vein" 8' below top of 3d S. S. at 528'. 



The oil sand was of uniform color [white and pebbly] with the softest 

 stratum on top, and appearances indicate that nearly if not quite all the 

 oil comes in the well at 5 or 6 feet below the top of the 3d sand, be- 

 tween which points both torpedoes were exploded. 



This well was pumped about thirty days, part of the time with a gas 

 pump attached and part of the time without one.* The largest natural pro- 

 duction without the gas pump was 4 barrels per day. The first day after 

 the gas pump was applied the production increased to 6 barrels, from which 

 point it gradually declined to less than 4 barrels. 



On the 21st of November, 1870, it was torpedoed at a point 5j feet below 

 the top of the 3d S. S. It then produced 160 barrels per day for the first 

 few days, but gradually declined to 13 barrels per day by the 1st of June, in 

 the following year, 1871. The gas pump was again tried with no satisfac- 

 tory results, and taken off as worthless or of no benefit to the well. 



On December 21st, 1871, the production had declined to 10 barrels. A 

 one quart nitro-glycerine torpedo was then exploded in the oil sand, which 

 increased the production to 40 barrels per da3^ But this continued only a 

 daj' or two. It immediately commenced decreasing, and on the 1st of 

 August, 1872, about two years from the time it was first pumped, it had 

 declined to its first natural production of 4 barrels per day. 



During this month, August, 1872, the "volcanic treatment" was tried 

 upon the well at three different times. The first time 4 burners were used, 

 resulting in a slight increase of gas, but no increase of oil.f 



The second time 7 burners were used, same results. 



* Every oil well has more or less gas, which, separating from the oil at the bot- 

 tom of the well rises between the tubing and casing and escapes through a pipe 

 provided for the purpose, at tVie well mouth. A " gas pump " is an instrument 

 which is attached to this escape pipe to relieve the rising gas from atmospheric 

 pressure and thus facilitate and increase its flow. In many cases it not only 

 augments the flow of gas but very materially improves the oil production of 

 the well. A "Rotary " or " Gas Blower" is sometimes used for the same pur- 

 pose. 



t The "volcanic burner" is a patented article designed to increase the pro- 

 duction of a well by intensely heating the fluid at the bottom. It consists of 

 a case filled with chemical ingredients. After lowering it to the desired spot 

 the materials are ignited by an electric spark. The operation is repeated until 

 the desired heat has been obtained, when the tubing is at once put in and 

 pumping resumed.
