INFORMATION CIRCULAR NO. 42 7

Gulf Coast Realties Corporation wells, both of which have been abandon-
ed. When this perforated interval-,i,n theNo. 18 well is depleted or goes
to salt water, perhaps overlying intervals which have produced in other
Sunnnijland field wells will be opened to production.

 This well was drilled to a total depth of 11,806 fee and the bottom
of the Chamid zone appears to have been reached at a depth of about
11,604 feet. It is possible that the operator had hoped, in drilling about
202 feet below the bottorniof the Chamid zone, to find a third pay interval
in the underlying Coskinolinid zone. A promising pumping test of this
underlying zone, made through perforations 108 to 130 feet below the
bottom of the approximate stratigraphic equivalent of the Chamid reef
and in the lower part of Bank's Dade Cyclothem Unit D-2 (1960, p. 1740),
was conducted in the Commonwealth, et al., No. 1 M. B. Wisehart and
State Board of Educatiori well of the Forty Mile Bend field, shown on
figure 1 to be located about 48 miles southeast of the Sunniland field.
In this test the zone (11,464 to 11,486 feet) was acidized, and recovery
was 20 barrels of 230 API gravity oil plus considerable salt water.

 The Humble ,Oil .and .Refining Company, No. 5 Lee Tidewater
 Cypress Lumber Company "'B" well is a new producer which occupies
 an infield location at a point approximately 0.4 mile equidistant from
 the four producing wells previously drilled by the Lee Tidewater Cypress
 Lumber Company. The four producing wells surrounding the new pro-
 ducer have been in production for periods ranging from 14. to 15 years.

 Recovery on a 9-hour pumping test of this well from a perforated
 interval in the Chamid zone from 11,580 to 11,585 feet (-11,543 to-11,548
 feet subsea) was: :
 108.7 BOPD (25.30 API gravity)
 0.7 percent BS&W
 It is shown in table 2-that the top of the middle member of the
 Sunniland formation in this new producer occurs at 11,540 feet (-11,503
 feet subsea).. On this marker the well is not as high as the previously
 discussed Gulf Coast: Realties Corporation. No. 18 test, but it is higher
 than any of the four surrounding Lee Tidewater Cypress Lumber Company
 producers by amounts ranging from 8 to 18 feet. Despite the fact that
 these two new producers drilled in 1962 are structurally high, the per-
 forated intervals in both of them are somewhat lower in structural elevation
 than they are in surrounding-producers. When these intervals are depleted
 or go to salt water, perhaps overlying zones which have produced in the
 surrounding wells will be opened to production.
