Dixie Oil Pool, Caddo Parish, Louisiana

Abstract

The Dixie oil pool is really a southeast extension of the old Caddo oil field, about 3½ miles from the old producing area and within 10 miles of the city of Shreveport. It was discovered in April, 1929, by the D. C. R. Oil Company (D. C. Richardson). By the end of 1929, thirty-seven producing wells and thirty-two dry holes had been drilled within a 3-mile radius. The wells penetrate the normal section of Eocene and Upper Cretaceous formations. The oil is produced from the basal sand of the Tokio formation, just above the unconformable contact with the Lower Cretaceous upper red beds of the Trinity group. No oil has been produced from the Lower Cretaceous beds in this area. The Dixie pool is on the Sabine uplift, but the local structure is only a terrace on a slight anticlinal nose, with oil accumulation in sand lenses deposited in basins in the Lower Cretaceous surface. The lenticular condition of the sand has caused a large percentage of dry holes. Features of the geologic history of the Dixie area and the older Caddo field, as shown by recent deep drilling and geological investigations, are briefly discussed. In 1929 the Dixie pool produced 588,415 barrels of oil, all of approximately 42° gravity, valued at more than $1,000,000. Future production depends largely on additional drilling; hence, it can not be closely estimated.
