In recent years significant quantities of offshore natural gas have been discovered in the area known as Aphrodite in Cyprus' exclusive economic zone (EEZ), about 175 kilometres (109 miles) 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, and with Lebanon in 2007. Cyprus and Israel demarcated their maritime border in 2010, and 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.
