Show restoration OF OIL WELLS an electric heater designed to cause the ren renewed devred flow the general theory concerning the exhaustion of so many oil wells is that thai the oil in passing through the stone las clogged the porous stories stones with in such quan quantities titles that the further flow is stopped and the well cea beb to produce in many cases says the age of steel the supply in the earth has not given out but only ceases to flow when the exit Is stopped the store through which the oil passes iso is of favery a very porous parous nature and as aa the liquid is in a crude statz state the thick matter becomes RS as dregs settling in the rock near abe adges of the bottom of the wei efell tor x aloes have been used to shatter tae tone at the bottom bottorof of the well thus brcak ingup the clogged mat mater ter but this method is expensive A new method cone consists isas in lowering a peculiarly lecul arly een con strutted ted electric heater into the well 11 the machine which is eia eight feet ions t and nd ri resembles E ambles an iron cartridge is i rl placed iced in ia the bottom of the wel and th tb current regulated so that the heater hearter receives just enough to produce an enormous heat beat without melting the metal 13 by ay thi this spec peculiar culiar construction ati the carbon packed char chambers abers the intense heat is radiated about into the rock reek in all directions thus the anil other refuse are softened an ani and I melted up s so that fiat they run and when the well weh is started a fresh flow takes place just as strong as it did when the well wax just sunk |
