Ben Caspit speaks this week with veteran geologist Yossi Langostsky, considered the founding father of natural gas discoveries off the Israeli coast. Langotsky recounts that the first discovery took place in 1999, when he himself asked for an exploration-drilling permit for gas and oil, deep into Israel’s economic waters. Ten years later, actual drilling started, in an area Langotsky labeled the Tamar field, after his eldest granddaughter. The renowned geologist explains that the Tamar field could supply Israel with all the natural gas it needs for a period of 25 years. He also believes there is potential for discovering oil in the same region. Still, such exploration, he says, would require much deeper drillings and much more costly procedures.
