The discovery that an additional strata in the Tamar gas field contains natural
gas has broad implications for the other gas fields in the region, sources in
the natural gas industry believe.
A prospectus published by Delek
Drilling LP on Thursday night said that a new gas reservoir has been discovered
in a fissure in which Tamar 2 is being drilled, including a strata of sand with
an overall thickness of 25 meters (D strata).
The reservoir was
discovered at the Tamar 3 well at a depth of 5,160 meters beneath the three
secondary wells discovered in Tamar 2 (A, B, and C strata). Estimates are that
the new strata of gas discovered in Tamar’s deep sands contains 0.5-1.5 trillion
In its prospectus, Delek Drilling disclosed that Netherland
Sewell & Associates Ltd. had revised the volume of gas reserves for
development in Tamar upwards on June 30 from 8.7 trillion cubic feet to 9.1
trillion cubic feet.
The new quantities of gas that might be found in the
D strata may not be sensational relatively speaking, but to put matters in
proportion the size of Mary B field in Yam Tethys that has been supplying 75
percent of Israel's natural gas consumption since 2004 is only 500 billion cubic
But perhaps most interesting of all is that Delek Drilling’s latest
report about the Tamar prospect also has implications for Leviathan, which
covers an area three times as large as Tamar. The Leviathan 1 well contains 16
trillion cubic feet of gas. The discovery that Tamar’s gas potential is larger
than thought could also prove significant for the Myra, Sarah and other
Delek Drilling hinted at such a possibility, when it said that
the operator Noble Energy is collecting data about the D strata and “is working
to analyze the possible implications of the discovery of the reservoir for the
volume of reserves at Tamar and for other finds in other oil assets of the
Meanwhile, Myra and Sarah license-holder Modiin Energy LP
notified the TASE on Sunday that the rig for the drilling of the exploratory
wells at the licenses will become available in December, after the rig completes
three other wells, two in Israel and one in Cyprus.
Earlier this month,
Modiin Energy's partner in the licenses, Israel Land Development Company Energy
announced that drilling of the exploratory wells by the Noble Homer Ferrington,
owned by Noble Corporation would probably begin in January or February 2012.
Modiin Energy said Sunday that this rig would be available from December 1.
