Description

The decrease in flow from Well No. 2 was likely due to the high lime content of the water forming scales over the perforations in the pipe, and Moss recommended enlarging the holes.

    (copy) Mr. Walter R. Bracken, Vice President, Las Vegas Land and Water Co., Las Vegas, Nevada. ROSCOE MOSS COMPANY 4360 Worth Street, Los Angeles, Calif., June 13, 1938. My dear Walter: In reference to your letter of June 10th, concerning the heavy drop-off in production of water from the well drilled during 1936, would state I have carefully examined the log of this well and also the one drilled in 1924. The noticeable difference is that the original well is producing from open hole between 572 feet and 635 feet, while the well drilled during 1936 is producing from perforations between 575 and 720 feet in depth plus the open hole between 720 and 802 feet. I well remember in drilling the original well considerable caving was had below 572 feet with undoubted enlargement of area and increase in quantity of water. The new well practically tripled in flow after perforating and we must therefore assume that the major portion of our water came through these perforations. 700,000 gallons per day through a 12 inch pipe should carry a reasonable quantity of sand out of the well, but I am a little inclined to believe the hole will be found clear. Due to the lime content in the water and the formation itself it is possible that the perforations are being closed through a cementing process and such action would account for your reduction in flow. Additional perforation or opening up of the old ones should restore the capacity. I would advise one of our well rigs best suited to Las Vegas go into the well and if we find it free from sand we would be in a position to open up the old perfor-ations or install additional ones as the situation might warrant. Should the reduced flow be the result of building up of sand in the wall it could be a simple matter to correct. In any event, we will have obtained information which should enable us to handle any like future situation. We estimate our cost exclusive of transportation to be from $300.00 to $500.00 dependent upon the work required. Trusting this information meets with your requirements, with kind personal regards, I am Very truly yours, ROSCOE MOSS COMPANY, By /sgd/ Roscoe Moss.
