The Mist gas field is still in the development stage. Although the field is complexly faulted and contains a submarine gorge, the general structure and stratigraphy are not unusual compared with other oil and gas fields in Tertiary basins of the West Coast. It is unique in one respect: it is the first commercial oil or gas accumulation to be discovered in the state of Oregon. More than 200 dry holes had been drilled in the state prior to the Mist discovery, May 1, 1979.

Production is from the Clark and Wilson (C and W) sands of Eocene (upper Narizian) age. The structure is a faulted anticline which is an en echelon continuation of the Portland Hills anticline.

Initial production rates range from 865 to 6,500 Mcf per day with an average of 3,400 Mcf per day for the first 5 wells completed in the field.
