The 23d-18 well, which was drilled directionally, 60 feet structurally below the 23d-17z well, penetrated an oil column of 50 feet with 25 feet of total vertical depth (TVD) net oil pay in the Ness formation, and an oil column of 15 feet with eight feet TVD net oil pay in the underlying Etive formation.
Modular dynamics testing over the oil bearing sandstones in both formations flowed light oil with no water. The equivalent Ness section in the discovery well tested light oil at rates up to 7,000 barrels of oil per day (bpd) with no water. The Etive section in 23d-18 represents a new oil accumulation not previously reported from this area of the Causeway structure.
The 23d-18 well is currently being cased and will be retained as a development well to provide pressure support to the 23d-17z discovery well, which tested at a combined rate of up to 14,500bpd.
