In recent years significant quantities of offshore natural gas have been discovered in the area known as Aphrodite (at the exploratory drilling block 12) in Cyprus' exclusive economic zone (EEZ), about  south of Limassol at 33°5'40″N and 32°59'0″E. However, Turkey's offshore drilling companies have accessed both natural gas and oil resources since 2013. Cyprus demarcated its maritime border with Egypt in 2003, with Lebanon in 2007, and with Israel in 2010. In August 2011, the US-based firm Noble Energy entered into a production-sharing agreement with the Cypriot government regarding the block's commercial development.
