Heletz History

The Heletz field is a complex of three fields, Heletz, Brur, Kokhav, is located nearly 55 km south of Tel Aviv and 12 km east of the Mediterranean coast line. The license area covers approximately 60,000 acres. Heletz was the first oil field discovered in the eastern Mediterranean and remains Israel’s most significant oil-producing field. The first well (Heletz 1) was drilled to a depth of 1515 meter and recognized as a producing well on 12 October 1955. Initial production was approximately 400 barrels per day; oil was 29 API.

• The main stages of Heletz oil field development, were:
  • 1955-1962: Drilling of 29 development and step out wells in the Helez area and 6 wells in the Brur area.
  • 1962-1968: The drilling of 25 additional wells, following the oil discovery of Kokhav 1.
  • 1969-1983: 7 wells were drilled.
• 88 wells were drilled during the lifetime of the Lease over an area of 4,500 acres, 59 of which were deemed producing wells.
• Peak production was between 1959-1967 when annual production was between 1 and 1.5 million barrels (3,000 to 4,200 BOPD).
• Today 6 wells remain capable of producing approximately 60 barrels per day.

Historical Production

• The original oil-in-place (OIP) was estimated at 50.7 MMbbl for the sand reservoirs.
• 19.1 MMbbl est. primary recoverable reserves.
• 17.1 MMbbl has been produced to date.

• Production primarily from Heletz sandstone intervals (the ”K” “W” “A” and “Z” sands)
• Minor production from the Kokhav Dolomite and top of Jurassic Limestone.
• Permeability ranges from 30-2000 md (50md avg).
