REMARKS: (1) This well is structurally the highest well in.the Sunniland field on the top of the middle
 member of the Sunniland formation (11, 527 feet). However, the perforated interval
 (11,585-11, 589 feet) in this well is structurally lower, by amounts ranging from 2 to
 18 feet, than the open hole or perforated intervals in any of the other wells in the field
 with the exception of the No. 1 and No. 4 Gulf Coast Realties Corporation wells.
 (2) Relative to perforation history and acidation:
 Originally this well was perforated from 11, 581-11, 585 feet, and the zone
 was acidized with 3, 000 gallons. These perforations were 4 feet too high
 and were therefore squeezed off with cement. Then the zone from 11,585-
 11, 589 feet was perforated with 16 shots.
 (3) Casing program:
 Set 20" at 116' with 250 sacks; 13-3/8" at 1,027' with 570 sacks; 9-5/8" at
 4,361' with 325 sacks; and 7" at 11,741' with 130 sacks.
