Los Angeles - June 10, 19^4 Mr. J. B,' Macki fCC - Hr.• :if* H. Bracken Mr. J. M. Anderson) After the unexpected production of 2,023, ©PM Incident to gun-nerforating Veil No. 10, Mr, Adamson made a careful com­putation of capacities of the various sixes of lines leading to the new settling baslnupon the assumption maximum production would foe turned into these lines from Wells Nos. 4, 7 , g, 9 , and 10. /He. finds all lines to have ample capacity, assuming maximum production of these several wells and including Nos. 4 and 7 on pump, and ample capacity in the 20* transits pipe from the settl­ing basin'to the reservoir assuming the reservoir full, except that the capacity of a few lengths of 10* C.I, pip© in the IP* line, between Welle | and 10 , is exceeded by the 2,023 0PM flow and is undoubtedly causing the back-pressure in Well No. 10. X do not know the circumstances surrounding the instal­lation of the 10* pipe. Our Work Order called for 12*. However, according to Mr. Anderson's report the 10* pipe is there and must be replaced, but X do not think it advisable to attempt replace­ment during the hot weather. I would like to have a report on just how much 12* pipe is required so that we may be prepared to shut in this well after the summer season and make the replacement. While we have arranged that Wells 4, 7* ©nd 9 be shut in for the present, we are satisfied from Mr. Adamson's investiga­tion (which X might add is confirmed by Johns-Manville hydraulic engineers) that we can cut In any one or all of these wells as water may be needed, and I request that Mr. Anderson instruct Bob Edvards accordingly; and if in Mr. Anderson's judgment we should flow No. & continuously to avoid repetition of the sanding trouble we have had, it is all right to keep that well on production, throttling down some other well accordingly.
