 SUNNILAND FIELD


 DRILLING ACTIVITY

 Activity in 1962 in the Sunniland field, operated by the Humble
Oil and Refining Company, and located in Collier County, Florida, as
shown in figure 1, has been greater than for any year since 1949. Two
new wells have been drilled and completed as producers; also, a permit
has been issued for the deepening of an old well. These tests, together
with ciher wells in the immediate area of the. Sunniland field, are shown
on figure 2, a location map.

 Production in the Sunniland field is from a fossiliferous carbonate
 section occurring in the upper part of the middle member of the Sunniland
 formation of Lower Cretaceous Trinity Age, as defined in Raasch's type
 section (1954, p. 8). Production and structural statistics on field wells
 which have produced commercial quantities of oil from this section,
 including the two wells drilled in 1962, are presented in table 1, which
 reveals the following facts: (1) Most of the 16 Sunniland field wells
 have been good producers, with one well producing about 1 1/3 million
 barrels of oil, while two other wells have produced almost a million
 barrels each; (2) the last two columns of this table show that generally
 less water is produced from wells that are structurally high than from
 wells that are structurally low; also, the percentage of salt water pro-
 duction by individual wells has increased markedly; (3) since all of
 the wells produce large percentages of salt water at the present time,
 it is inferred that most of the production is from a gradational zone rather
 than from above a sharp oil-water contact.
