HAVANA, Feb. 7th The Alameda-1 exploration well in Cuba has delivered more evidence of oil in one of the primary reservoir targets and is drilling ahead to the final zone of interest.The operator Melbana Energy said drilling reached a depth of 3590 metres when a lithology change was detected, potentially signifying the bottom of the N reservoir.
The interval began at about 3077 metres, indicating a potential gross reservoir interval of as much as 500 metres, accompanied by high gas pressure.
The next step is to log the section just drilled, and this should give a better understanding of the hydrocarbons that have been encountered.
The seven-inch liner will then be set before drilling ahead into the deeper zone with a six-inch hole to test the Alameda structure — the second and largest primary target.
Melbana Energy’s executive chairman Andrew Purcell said: “This well is not affording much chance for rest for our hard-working team here on the ground in Cuba, but no one is complaining given what this well continues to tell us.
“We’re all looking forward to the results of the forthcoming logging programme to learn more about this extensive oil interval we’ve intersected.”
The significance of all the oil shows — including from an unexpected shallow interval discovery — need to be determined by wireline logging.
Alameda-1 was spudded in Block 9 on 13 September 2021 by a joint venture of Melbana Energy and Sonangol.
Following the completion of Alameda-1, the rig will be moved to the well pad that has been constructed nearby to begin drilling the Zapato-1 well.
