Cyprus
Exploration Wells

Since 2011, 11 wildcats have been drilled in the Cypriot EEZ, and 6 of them found gas — a strike rate most frontier basins never see. No well has come back dry since 2018.

What the wildcats found 11 wells
6 Discoveries Aphrodite, Calypso, Glaucus, Cronos, Zeus, Pegasus
2 Gas shows, sub-commercial Onesiphoros West-1, Elektra-1
3 Dry Onasagoras-1, Amathusa-1, Delphyne-1 — all before 2019
+4 appraisal wells re-drilled fields that had already been found. They confirm volumes; they do not add discoveries, which is why the count here is 6 and not 9.

The drilling record

Every well ever drilled in the Cypriot EEZ, in the order it was spudded. Bar length is the water depth the rig had to reach before drilling even began.

6 of the 15 wells sit under more than 2 km of water and the shallowest, Amathusa-1, still had 1,600 m above it — this is a deepwater play by definition, which is why so few wells get drilled here. Depth below the seabed is a different number, published for only 6 of the 15 wells; where it exists it is on that well's own page.

Who has been drilling

All 15 wells were drilled by 5 operators, and two of them account for 11. Each row reads chronologically, so a campaign's learning curve is visible in the colour.

discovery appraisal, confirmed gas shows dry not reported
Eni 6 wells Two dry holes in Block 9, then four straight hits in Block 6 — Calypso, Cronos, Zeus and the Cronos appraisal.
ExxonMobil 5 wells Missed at Delphyne, then found Glaucus and Pegasus — together the largest resource concentration in Cypriot waters.
Noble Energy 2 wells Opened the basin: the first well ever drilled in the EEZ found Aphrodite, and the appraisal flowed 56 MMcf/d.
TotalEnergies 1 well Gas at Onesiphoros West in Block 11, but not enough of it to develop.
Chevron 1 well Drilled the 2023 Aphrodite appraisal. No result has ever been published for it.

What a Cypriot well actually is

Roughly two kilometres of water, then another one and a half to four kilometres of rock before the bit reaches the carbonate reservoirs that hold the gas. Aphrodite-1 went to 5,860 m through 1,689 m of water and took just under four months, from spud in September 2011 to completion that January.

Well list follows the official hydrocarbons.gov.cy table; unlicensed Turkish drilling (2019–2020) is excluded, as it is in the Republic's own well counts.
