Paxos and Hydrocarbon Deposits, Past Oil Exploration and Research; Environmental Impact; The Ionian Sea Block 2; Corfu



Edward Lear's Paxos


With recent talk of renewed oil/ hydrocarbons exploration in the Ionian Sea and in Epirus, I am reminded of the distress and anxiety caused to many residents of the island of Paxos (Paxoi) thirty or forty years ago.

As someone who contemplated the possibility of building on the island in those days, all my planning was halted when AGIP began thumping the ground for seismic soundings; they made the very earth tremble all around the beautiful island, which I had come to care for deeply.

Bogdanatika is a village not far from Gaios, the main port of Paxos. Building permission was obtained back then for the construction of a small house in the village of Bogdanatika, but AGIP 's plans to explore and to drill for oil (and to use the nearby football pitch for its base camp), put paid to any such romantic and nature-loving ideas.

I did not share the optimism expressed by Sotiris Kostopoulos in 1984:







I could agree with the first two sentences above:





But even the mere threat of such disruptive and destructive exploration had an environmental impact...in spite of promises about modern technologies.

Some online background research (for specialists, I am unsure how relevant these papers may be):

Abstract

"A spectacular slump is observed in the Alpine sediments of the Antipaxos Island (Pre-Apulian zone, Western Greece). It can be followed in a zone of about 2000 m, in the eastern coast of the island. The slumped unit exposure length extends for more than 200 m, and is directly overlain and underlain by undeformed strata. The slump has an average thickness of 15 m and is composed, as the surrounding undeformed units, of calcareous mudstones and fine-grained calcareous sandstones. Synsedimentary folds that very often are transformed to contorted beds affect slump sediments. Fold and contorted bed axes present a NNW-SSE direction, coinciding with the general direction of the Pre-Apulian zone. Slump and overlain/underlain undeformed sediments originate from the flux of clastic mainly pelagic/neritic biogenic particles, emanating from turbidity currents. More than 50 samples have been collected and analyzed for calcareous nannofossil content. All samples were featured by the contemporaneous presence of abundant nannofossil flora implying the biostratigraphic correlation with the NP23 nannofossil biozone. The biostratigraphic assignment places the slump and the surrounding sediments to the Early Oligocene. As the Pre-Apulian zone corresponds to the slope between the Apulian Platform and the Ionian Basin, the presence of the slump is directly related to the same age sloping and tectonic mobility of this domain. The Antipaxos turbidites sediments are well integrated to the flysch deposition of the external Hellenide foreland basin system".
