the present work on the hole.
The Engelman wildcat Is being re-
worked and tested on the basis Of

Men the hole was originally car
led to 1903 feet by Union Sulphur
company. When Union abandoned
the hole, Il was plugged back to
$3.50. Gulf States took over a por-
ton Of the acreage and the old
hole and went In TO test the low
est sand az 5.~650-6,700 feet. The
new operators set an 80-foot cement
plug on the original plug, making
total depth 6,77O feet. A 5O0-foot
string of 6% inch o. d. casing, the
lower 80 feet perforated, was set on
bottom at 6.770 feet and 8 full-hole
cement job was done around the up
per $50 feet Of the string to hold 1t
firmly in place. This string was
set In order TO obtain a seat for
drill stem test. When the testing
tool was run into the hole. 1t was
seated with q hook wall packer at
h Reut $3.50 feet but nc test vas OBJ
"a. Failure Of the packer 70
operate properly caused the entire
string to stick. 1t Is believed that
efforts TO remove the string opened
the testing tool. resulting In the
gas and fresh water flow recorded
last week. The flow was killed with
heavy mud late IN the week and
operators decided to cement the
drill stem inside the 10-inch sur
face casing and use the drill stem
rs 4-inch casing. This work was
completed Monday morning and
the Sole is now being bailed through
the drill stem.
