Libya's National Oil Company (NOC) had signed a memorandum of understanding with Turkish state oil company TPAO to conduct a geological and geophysical study of four offshore areas, NOC said on Wednesday.

"Discussions were also held regarding conducting a two-dimensional seismic survey (10,000 kilometres long), and processing the data resulting from these surveys within a period not exceeding nine months," Libya's state oil firm said in a statement.

NOC said the agreement was signed in Istanbul by the two companies' executives. It provided no further details.
