Title: The Cotton Valley, Louisiana, Oil Field

Author(s): Worth W. McDonald

Abstract:

The Cotton Valley, Louisiana, oil field has been an unusual field in the respect that the greater part of the structure produced large gas wells while at the outer extremity many gusher oil wells were brought in.

The first wells drilled were large, dry gas wells with a pressure of 1,200 pounds and 60,000,000 cubic feet of volume. Later, as the pressure decreased, these wells began to spray oil.

Many irregularities in production were encountered. Salt water occurred high on the structure and at shallower depths than found on the lower part of the structure.

These irregularities are explained as being due to the conditions under which the reservoir was deposited and irregular cementation of the sand grains.

The production is from the Blossom sand. Lower sands have not been thoroughly tested.
