MISSION, March l6.-Extension
OF the Samfordyce, field OF south
western Hidalgo in every direction
Is being attempted In tests either
now drilling OF oon to get under.
according TO announcement Of oper-
atorS during the past week.
The week, one OF the busiest since
completion OF the discovery well last
September, was featured BY compile
ton Of four new flowing wells to
bring the fields total 70 ~ now on
production. IN addition 10 the pro-
ducers brought in, three tests have
set and cemented casing and will pe
drilled in during the weekend.
Wildcat activity In both Hidalgo
and Starr counties Slackened slight

T~g7-2.8O0 feet. The significance OF
the Skelly test Is the fact that u
made oil on drill stem tests Of both
upper and lower sands. whereas IN
most sections or the field, the upper
sand carried only gas under high
preSsureS. This condition has caus-
ed considerable trouble for operators.
including two wild wells which
eventually were brought under con-
troll. From the upper sand al 2.7S0-
81 feet, the Skelly hole tested 1000
feet Of oil and 80 pounds gas pres
sure in about six minutes. In the
lower sand, 1t tested 2,288 feet OF oil
without pressure In 20 minutes.
These showings Immediately revived
interest In the northwest section OF
the field and the possibility OF *
