Origin confirms Jingemia 8 (49.189%) found oil-saturated Dongara Sandstone from 2,482m, about 30m above the original oil-water contact. Pressure data shows it is not connected to the rest of the field. The well will be completed and connected to the Jingemia facility.

Victoria Petroleum relays that logs show the whole Dongara Sandstone section in Jingemia 8 is oil-saturated, and its pressure suggests a separate up-dip compartment. The well will be cased for production. Victoria's 4,000-5,000 bbl/d target is its own view.
