South Princess Syndicate No. 3 Gives 930 Ft Oil Rise In One Hour Drillstem Test Madison Lime Top

SOUTH PRINCESS SYNDICATE No. 3, LSD 12 8-19-11w4th, has given the best drillstem test oil performance yet recorded from the Madison Limestone in the general PRINCESS Area, and appears slated for commercial production. The important well is located 1 ½ miles north and a mile west of the South Princess No. 2 Madison Discovery, and is 2 ¼ miles south and 3 ¼ miles east of the Empire Pacific No. 2 Madison Discovery. It is the first test in the six-mile stretch separating those earlier completions.

S.P.S. No. 3 topped the Madison Limestone at 3,315 ft 24 ft lower in elevation than the contact at S.P.S. No. 2 and 10 ft lower than the lime elevation at EP No. 2. Coring, was halted 5 1/2 ft in the lime at 3,320.5 ft, and one hour drillstem test was run Wednesday with Packer set about 11 ft off bottom.

The well commenced making gas at a rate of 1,000,000 on ft daily when tester was open with gas flow rapidly dropping as fluid entered the pipe. When the 4 ½" pipe was pulled it was found to contain a 930 ft column of gassified, black clean crude oil (estimated gravity somewhere between 25 and 28 degrees API), plus 30 ft of drilling mud. There was no sign of free water. Electrolog was being run Thursday, after which casing will likely be run and set.

To compare with earlier Madison completions in the region: EMPIREPACIFIC No. 2, lsd 16 22-19-12w4th, topped Madison in July 1945 at 3,302 ft, with varying porosity showing 3,306-19 ft. Test of full section gave gas flow 2.5 million on ft daily against 1,625 Pounds bottom hole flowing pressure, plus a small amount of oil.
