"Israel's Leviathan field may also have oil"

Partners in Israel's offshore Leviathan natural gas field said that new tests reveal the possibility to find up to 4.2 billion barrels of oil below the underwater gas field in the Mediterranean Sea...

The operator Noble Energy hasn't put out a release on the subject, but the Israeli partners have and it seems to me that the Upstream employee has interpreted the contents incorrectly.

Delek Energy Provides Update on the Drilling at Leviathan 1 Well

B. Secondary objectives – Leviathan Deep Prospects Targets

After completing electric logs and other evaluations on the NG10 interval in the well, the drilling will be deepened for the purposes of collecting and testing of engineering and geological information, for the secondary goals which are listed below. It should be emphasized that the current information is significantly less than that which exists for the prospect NG10, and therefore very difficult to assess whether these targets may contain oil and/or gas and what would be their corresponding resource potential of the hydrocarbons in the prospect, and the probability of their existence. Based on the above it is stressed that it is highly unlikely that commercial quantities of oil and/or gas will be found.
1. Leviathan Lower Oligocene Prospect Target

This prospect is of the Lower Oligocene Age, at a total depth of about 5,800 meters, including water depth. Noble estimates based on seismic information in its possession, that the prospect’s Gross Unrisked Mean Resource is equivalent to about 3 billion barrels of oil. However, the probability does not include the geological probability of finding hydrocarbons in this prospect. The geologic probability of finding hydrocarbons at this prospect (Pg) is estimated at 17%.
2. Leviathan Lower Cretaceous Prospect Target

The partners intend to continue drilling to Lower Cretaceous age layers, to a depth of about 7,200 meters (including water depth). Noble estimates based on seismic information in its possession, that the Gross Unrisked Mean Resource potential of oil or natural gas reserves is approximately equivalent to 1.2 billion barrels of oil. However, the probability does not include the geological probability of finding hydrocarbons in this prospect. The geologic probability of finding hydrocarbons at this prospect (Pg) is estimated at 8%.
