Be it known that I, FRANK O. Brown, a

i citizen of the United states, residing at Dai..

las, in .the county of Dallas and State of Texas, have. invented certain new and useful Improvements in Methods of Raising Fluids from Artesian lWells, of whiclrthe following is a specification.

My invention relates to a new anduseful method for raising luids from Artesian wells, and' the object of my invention is t0.

' the accompanying drawing, wherein:

Figure 1 is a plan view of a series of wells connected at their bottoms by channels shown in dash line. Fig. 2 is a sectional elevation, the section being taken upon the line .fn-z of Fig. 1-

Like reference characters are employed to' designate similar parts in both figures of the drawing.

TheA numeral 1 denotes'a series-of' bored n wells arranged in the arc of a circle and 2 denotes :another bored well situated at the center of said arc. The wells 1 and 2 are sisting of send or extended 'through the surface soil 3 and through the ca ,rock 4.- into the bottom portion of the Hui bearing strata.I 5 usually conavel. The projecting upper-'extremities or the well forming pipes Y vare capped as at 5*, this being a preliminary ste m carrying out my method. The centerl we 2 is now connected up through a owerful .Iorcepump with a water orot er fluid su ply. One of the wells 1 is now uncap and is connected with a pipe to conduct a fluid to be pumped from the well. The pump is now put into operation, forcing the? fluid into the well 2, and exerting-a strong ressure' upon the medium constituting the The fluid will gradually permeate the strata 5, and on reaching the unca ped well 1 will rise therein and con ucted fromfthe uid bearing strata..

top thereof lby said pipe. The pump will be maintained in operation until the fluid in its assage from thewell 2 to the uncap wel 1 has formed a passage 6 in 'the uid bearing strata, the material removed in forming said channel being carried up and out of the uncapped well due to the pressure acting u onthe fluid. The well I which during t e operation above described has been unca ped is now closed, and another of the we ls 1 is uncapped. The-pump isy again set into operation, and another c nel 6 1s thus formed. This operation is repeated until there has been formed a channel QFICE,

ratented aliii4, 1914ibv 6 between the well 2 and each of the wells 1.

The well 2 is now disconnected from the pump and is closed or ca ped at its projecting upper end. One of t e wells 1 will now be unc'apped and the well 1 adjacent thereto will, be connected with the pump. The pump will now be put intooperation 'orcin some fluid down the well 1 with which it 1scon nected and causing-'the Huid to rise in the 'uncapped well producing a channel 7 be tween the two wells. This operation will be repeated until all of the wells lare connected at their lower ends b a channel 7. During the time that the wel 2 and each of the wells 1 is connected with a high pressure pump, the fluid escaping at the lower end of the w'ell will form sump or pit 8 in. the

'fluid bearing strata. just beneath the as is best shown in F' After the channels 6 and 7 have been a' powerful air compressor, and after one or more of the wells 1 has been uncapped, the i.

compressor is set in operation. The Artesia!! water or oil which has accumulated in the passages 6 and 7 will be subjected to an air pressure suilicient to force water or oil up through'the uncapped wells, which willbe connected with pipes 9 to conduct the water or oil where desired The numeral 10v designates a. valve provided in each-of the pipes 9 to control the dow of oil or water through said pipes.

Ini a. well in which the normal height of the fluid is equal to or greater than one-half the entire depth of the well1 it will be neces- 'sary only to force the air near to or slightly above the bottom of the wellin order-t0 cause the oil or water to ow out of said well'. Under such conditions, no more wer willbe required than is am zo ld the pressure as( stated until the uid formed, the center well 2 is connected with has been exhausted from the strata 5. Consequently there is no continuous escape off air to the surface until all the oil o r water is exhausted, after which the air will com mence to escape and it will then be necessary to closet e well in order to confine the air.

The operation above described will con- ,I tinue until all the fluid in the entire strata able pipes with a duplicate system of wells sunk in another portionof the fluid bearing strata, the air being permitted toescape from the first series of wells into the ysecond until the air pressure in the two series oi wells is equalized. The well 2 of the rst series will now be connected with an air compressor and the balance of the air in said first series will be forced therefrom into the second series of wells. After a sumcient air pressure has been created in the second series ofv wells to force the oil or water from theA channels '6 and 7 of said wells, the communication between the two series of wells will be cut o by assuitahle valve and the wells 1- of the first series will be uncapped to relieve the air pressure in the channels 6 and 7 of the first series so that the oil or water may again accumulate in said channels. It is thus seen that my method is carried on intermittently the op-l eration being int'erru ted periodic y for a sufficient lengthA of time' to allow the channels 6 and 7 to be replenished with-oil or water.

In case only-'onerseries of wells is employed in putting my method in operation,

after the oil or. waterhas been exhausted from said wells and from the channels 6 andv 7, the compressed air may be allowed to escape rom the wells into a receiver on the surface until the rassure in said .receiver and in the well is equalized. An air compressor may lthen be employed to withdraw the balance-o the compressed nirjrom v,incapaz i Vconnecting the same, su

the wells and channels .forcin the same into the receiver and reducing t e rassure within the wells to that existing un er nor mal atmospheric conditions.

-My invention is presented as .including 5I all such modifications and changes as properly come within the scope of the following claims:

WhatIclaimis: Y 1. A method of establishing communication between the-lower ends of two bored wells extending into a sand or gravel strata., consisting in pumping water under high lpressure into one of the wells causing itvto' force a passage through said strata lo the other well.- 2. A'inethod of raising uids from a subterranean Huid-bearing strata, consisting in boring two adjacent wells into said strata,

forming a channel between the lower ends` of said wells forcin compressed air into one of the-wells, there y forcing out through the other well the fluid normally standing in both wells and in the passage connecting the same, subsequently connecting either well l5 with a receiver equalizing the air pressure in l the receiver and wells, and then pumping air from the wells into said receiver until the air pressure in the wells becomes substantially atmospheric. 80 3. A. method of raising iuids from a subterranean duid-bearing strata, consisting in forcing compressed air into one of two wells extending into the strata. and communicat .ing at their lower ends, thereby forcing out through the other well the fluid normally standing in both wells md in the passage uently connect Y ing either well with a -rece1ver,. equaliz air ressure in the receiver-and wells, an 96 l,

fina y pumping air from the wells into said receiver, until the air prmre in the wells becomes substantially atmospheric.

In testimony whereof` vI have-signed mytwo subscribing witnesses. e
