( o o p y ) R 0 S C 0 E M O S S 0 0 M P A H Y 4360 Worth Street, Los Angeles, Calif., J u n e 13, 1938* Mr* Walter R. Bracken, V i c e President, Las Vegas Land a n d Water C o . , Las Vegas, Nevada, My dear Walter: In reference to your letter of June 10th, concerning the heavy drop - o f f in p r o d u c t i o n of w a t e r from the w e l l drilled d u r i n g 1936, w o u l d state I have carefully examined the log of this well and also the one drilled in 1934, The noticeable difference is that the orig­inal well is producing from open hole between 572 feet a n d 635 feet, while the w e l l drilled d u r i n g 1936 is produ c i n g from perforations between 575 a n d 730 feet in d e p t h plus the open hole bet w e e n 730 and 803 feet* I well remember in dril l i n g the original well considerable caving was h a d below 573 feet with u n ­d o u b t e d enlargement of a r e a and increase in quan t i t y of water. The n e w well practically tripled in flow after perforating a n d we must therefore assume that the major portion of © $ r water came through these perforations. 700 , 0 0 0 g a l l o n s per day through a 13 inch pipe should carry a reasonable quant i t y of sand out of the well, b u t I a m a l i t ’le inclined to believe the hole will be f o u n d d e a r . Due to the lime content in the w a t e r and the formation itself it is possible that the perforations are being cl o s e d through a cementing process a n d such a c t i o n would account for your reduction in flow. A d d i ­tional p e r f ormation or opening u p of the old ones should restore the capacity. I w o u l d 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 b e in a p o s i t i o n to open # p the old perfor­ations or install additional ones as the situation might
