SYDNEY, AUSTRALIA (13 APRIL 2022)Melbana Energy Limited (ASX: MAY) (Melbana) is pleased to provide this update on its drillingoperations in its Block 9 contract area, onshore Cuba (Melbana’s working interest 30%).Total depth for the Alameda-1 well was called at 3,916 mMD / 3,694 mTVD1 due to the significantand highly pressured influx of oil and gas into the well bore at that depth. Mud weight wassubsequently built up to bring the well under control, following which most of the roughly 300 mMDsection that had been drilled to that point in the Marti structure was filled with cement to isolate thishigh-pressure zone. The plan was to then drill a short side track starting above this cement plugso that oil samples could be taken from this shallower (hence, slightly lower pressured) section ofthe significant oil interval encountered in the Marti structure2.


Page 2 of 2Before drilling of the side track could commence, oil once again started to flow into the well bore;probably due the reservoir pressure previously encountered at total depth exceeding the strengthof the ~250 metre cement plug that had been put in place. Control of the deepest part of the Martiinterval will now be established by setting a liner below the shoe of the previous section andcementing it in place.
