Chamberlain Weil on Cat Creek's We#4o<ne Flowing More Than
400 Barrels of Pipeline OH Daily From Pay Zone a Deep Sand One of the best wells completed in Montana in many months has been brought in by Ralph Chamberlain of Great Falls, veteran Montana operator, on the Rhens lease at the western edge of Cat Creek's West Dome. Perforated with 62 shots in the Morrison sand from 1735 to 1783, the well is flowing a gallon of pipeline oil every three seconds, which according to field mathematicians gives it a flowing initial of ap proximately 480 barrels daily. The lease on which the well was drilled.had been operated by Chamberlain for years , and before deep sand development began in this field, was down to a daily total output of about 14 barrels, from 10 shallow first and second sand producers. Last year Chamberlain deepened one of the old producers through the third Cat Creek water sand and into the Morrison sand, getting a production of about 40 barrels daily, pumping, from this horizon— or almost triple the former output of the lease. This well was promptly offset to the east by the Continental Oil Texaco Gets Best Wells, North Field Best completions of the Week in the Kevin - Sunburst field were registered by the Texas Company, all la the field's most heavily-drilled area.

This is now the deepest well ever drilled on this vast structure, from the standpoint of both stratigraphy and footage. Likely to have a profound effect on future oil development over a vast arep, It is one of the most closely watched wells now being drilled In the entire nation. Greene Heads Union's Land Department R. G. (Scotty) Greene, former Union Oil company geologist known to many in Montana, has been named manager of lands and leases for the company. He replaces John L. Church, who has been appointed assistant to Union's Vice President John A. Rubel, on special assignment. A graduate of Stanford univer sity, class of 1923, Greene began his association with the company in 1925 as a geologist. His first assignment was in Venezuela where he remained until returning to Cal ifornia in 1929. Seven years later he severed his connection with the company to head up the Union Pacific railroad's geological depart ment. Since his return to Union Oil in November of last year, he has organized and established the com s northwest land division in tli Noon Wildcat Changing Rig W. A.

Wheeler of Casper and associates. Total acreage finally taken by Union in the two blocks was approx imately 32,000 acres, one block eluding the Six Shooter anticline, on which a substantial gas flow was found by a well drilled several (Continued on Page 2) in Program Announced For RMOGA Session In Denver, Nov. 21-23 CASPER—Entertainment will give stiff competition to the out- standing business sessions planned for the annual meeting of the Rocky Mountain Oil and Gas association to be held Nov. 21-23 in Denver, Colo., according to H.

Completion of the Chamberlain well, on the frii» c ; of what was the main producing area of the West Dome in the days of shallow sand development, is regarded as likely to bring about some drilling in what was the best parts of the main dome while first and second Cat Creek sand production was being sought. This dome produced most of the field's output of more than $25.000,000 in oil of around 49 gravity. Good saturation was cored in the Ellis sand in the Chamberlain well, but for the time being no effort will be made to test this horizon.
