The Tamar gas field is a natural gas field in the Mediterranean Sea off the coast of Israel. The field is located in Israel's exclusive economic zone, roughly 80 kilometres (50 mi) west of Haifa in waters 1,700 metres (5,600 ft) deep. The Tamar field is considered to have proven reserves of 200 billion cubic metres of natural gas, while the adjoining Tamar South field has 23 billion cubic metres. Together, they may have an additional 84 BCM of "probable" reserves and up to 49 BCM of "possible" reserves. At the time of discovery, Tamar was the largest find of gas or oil in the Levant basin of the Eastern Mediterranean Sea and the largest discovery by Noble Energy. Since Tamar's discovery, large gas discoveries have been made in other analogous geological formations dating back to the Oligocene–Miocene epoch in the Levant basin. Because Tamar was the first such discovery, these gas containing presalt formations have become collectively known as Tamar sands.
