Turkey is a minor oil and gas producer, with overwhelming reliance on energy imports - In 2018, Turkey's gas production met just 1% of domestic demand. Although Turkey is the second largest oil producer in Southern Europe, its oil output covered only 5% of demand. Continued reliance on imports and recent currency depreciation has increased Turkey's import bill. Valeura Energy (operator) and Equinor (50%)'s Thrace basin tight gas discovery in 2017 has the potential to reduce reliance on gas imports. The partners will complete a three-well appraisal programme by 2020. In the East Mediterranean Sea Turkey's NOC - TPAO, the largest domestic producer - has undertaken an exploration programme in contested waters, offshore Cyprus.
