Israel’s Offshore Natural Gas Discoveries Enhance Its Economic and Energy Outlook

Summary
Israel has been dependent on energy imports since it became a nation in 1948, but the recent
offshore natural gas discoveries could change that and possibly make Israel an exporter of natural
gas. Development of the recently discovered natural gas fields—Tamar, Dalit, and Leviathan—
likely will decrease Israel’s needs for imported natural gas, imported coal, and possibly imported
oil. A switch to natural gas would most likely affect electric generation, but could also improve
Israel’s trade balance and lessen carbon dioxide emissions. Regionally, Israel’s success thus far
has sparked interest from its neighbors to explore their boundaries for energy resources and has
raised concerns from Lebanon about sovereignty over the discoveries. Development of these new
resources, and possibly other discoveries, would enhance Israel’s economic and energy security.
Israel is in the early stages of formulating the regulatory framework to oversee the development
of these resources and may seek assistance from the United States or other natural gas producing
countries in weighing its options.
Key Points:
• The new discoveries—depending upon the actual production—could represent
over 200 years’ worth of Israel’s current natural gas consumption.
• Israel’s electrical generation sector will likely be the beneficiary of the new
natural gas resources.
• Additional natural gas and possibly oil resources may exist.

Israel’s Offshore Natural Gas Discoveries Enhance Its Economic and Energy Outlook

Introduction
Israel’s energy sector is set to undergo significant changes that could transform the country into
an exporter of natural gas. Development of three recently discovered natural gas fields—Tamar,
Dalit, and Leviathan (see Figure 1)—is projected to begin at the end of 2012 and be completed
by the end of the decade. The estimated supplies from these fields (see Table 1) would enable
Israel to decrease its natural gas and coal imports and possibly its oil imports.

Note: Resources or resource base is a broad term that includes reserves (see below) as well as natural gas less
likely to be produced. Resources are not subject to today’s technology or price constraints as reserves are and
may be produced sometime in the future. Reserve is an industry term to define the likelihood that natural gas
resources can be produced using current technology and at today’s prices according to the Society of Petroleum
Engineers and the World Petroleum Congresses definition.
Coal imports would likely be most affected as coal is currently the primary fuel for electric
generation, and can be displaced by natural gas. Israel’s trade balance would likely improve and
its carbon dioxide emissions would likely decline as a result. The discovery of natural gas
resources has also led Israel to reevaluate the nation’s energy tax policy. Israel’s Ministry of
Finance has recommended tax policy changes that would increase tax revenues, but decrease
potential after-tax profits for developers. Regionally, Israel’s success thus far has sparked interest
from its neighbors to explore their boundaries for energy resources and has raised concerns from
Lebanon about sovereignty over the discoveries.

Israel’s Offshore Natural Gas Discoveries Enhance Its Economic and Energy Outlook

Natural Gas Discoveries Improve Energy Security
Israel is poised to became an energy producer and perhaps even a natural gas exporter provided
its recent discoveries come to fruition. At the end of last year, Noble Energy, a U.S. independent
energy company, reconfirmed its estimates for its third and largest natural gas discovery off the
northern coast of Israel. The Leviathan field has an estimated resource base of 16 trillion cubic
feet (tcf)1 of natural gas, but will require at least two more appraisal wells to be drilled before the
size of the resource base is better defined.2 Noble Energy’s other natural gas discoveries (Tamar
and Dalit) coupled with the success of other companies puts Israel in a position to be self
sufficient in natural gas and possibly become a natural gas exporter, thus improving the country’s
energy and economic security.
Since January 2009, Noble Energy has made three natural gas discoveries—Tamar, Dalit, and
Leviathan—with an estimated 25 tcf of resources. Israel’s natural gas reserves—natural gas that
has been discovered and can be expected to be economically produced—prior to the Noble
Energy discoveries were estimated at 1.5 tcf or about 16 years worth at current production levels.
If only half the natural gas from the new discoveries is produced at today’s production levels,
Israel would have well over a 100-year supply of natural gas. It is too early to know the rate of
natural gas recovery from the three new fields or if other discoveries will arise, but it is highly
likely that Israel’s energy mix will move towards natural gas by the end of the decade. Tamar’s
first production is expected at the end of 2012, with Dalit one or two years after that, and
Leviathan between 2016 and 2018.3 According to Noble Energy, Tamar alone is expected to reach
a maximum capacity of one billion cubic feet per day (bcf/d) by 2013 or 2014, or over three times
the rate of Israeli consumption in 2009 of 0.31 bcf/d.4
Until 2009, Israel’s demand for natural gas was met by domestic production. An import pipeline
from Egypt began deliveries in 2009 and despite public discontent against the sales in Egypt, the
pipeline remains operational today (Figure 2 illustrates Israel’s natural gas consumption and
highlights the effect of Egyptian imports). Natural gas from the new fields could displace the
Egyptian imports, which has benefits and disadvantages for both countries. Israel pays below
market prices for the natural gas it imports from Egypt. Continuing the imports and using
additional production to begin exports, most likely to Europe or Jordan, could further improve
Israel’s energy and economic security. Eliminating the imports could improve Israel’s trade
balance and provide greater supply security. For Egypt, stopping the exports to Israel would have
political advantages as the natural gas sales to Israel were unpopular with Egyptians and were
taken into court. The impact of the current unrest in Egypt on its natural gas exports to Israel is
unclear. Maintaining the exports to Israel could help Egypt’s trade balance.

Notes: Production plus imports less exports equals consumption. Israel has never been an exporter of natural
gas.
Minimal Use of Natural Gas Currently
Israel’s consumption of natural gas has been growing since 2003, but remains a relatively small
portion of its current energy mix at 11%.5 Oil accounts for almost half of Israel’s primary energy
consumption, while coal is 35%. (See Figure 3.) However, the recent natural gas discoveries have
the potential to substantially change the share of natural gas use in Israel. Industry forecasts
project that by 2015, Israel could be consuming 1 bcf of natural gas per day, an almost threefold
increase from today’s consumption.6 The three new natural gas fields represent potentially 26
times the total amount of energy currently consumed annually by Israel from all fuel sources.
Israel’s electricity generation sector will most likely utilize the new resources more than other
sectors (see section below) and could even facilitate Israel moving towards electrification of its
car fleet, a goal the government has set. Current energy infrastructure is equipped primarily for
oil and coal; substituting natural gas would require major changes and investment to the
electricity and transportation sectors.

equivalent.
Electricity Generation Sector Likely to be Transformed
Israel’s electricity generation sector will most likely undergo the greatest change because of the
development of Israel’s natural gas resources. Currently, natural gas fuels about 26% of Israel’s
electric generation. (See Figure 4.) Coal supplies almost two-thirds of the generation capacity. If
Israel were to convert all of its existing electric power generation to natural gas, it would require
approximately an additional 0.8 bcf/d of natural gas,7 the estimated maximum output from the
Tamar natural gas field alone. Replacing only its coal units would require approximately 0.67
bcf/d of natural gas. If these conversions were to occur, carbon dioxide emissions from the
electricity generation sector would decrease 52% and 50%, respectively.8 However, this would be
a major investment and likely require many years to achieve.
Switching to a natural gas-based electrical sector would allow Israel to increase the domestic
share of energy production. Currently, Israel imports all of its coal and most of its oil.

7 This assumes utilizing high efficiency combined cycle gas turbines to generate the electricity. This type of power
plant is common and considered an industry standard for new natural gas generation.

Proposed Energy Tax Changes9
In April 2010, Israel’s Minister of Finance appointed a committee to examine fiscal policy related
to oil and gas resources in Israel, prompted by the recent natural gas discoveries.10 The committee
was directed by Israel’s Minister of Finance to (1) evaluate Israel’s fiscal system as it relates to oil
and gas reserves and compare Israel’s system to countries in similar economic circumstances; (2)
propose an updated fiscal system; and (3) examine the potential effects current and future natural
gas discoveries would have on the Israeli economy.11

The committee’s draft conclusions were released by Finance Ministry on November 10, 2010.12
The committee found that “the current system does not properly reflect the public’s ownership of
its natural resources.”13 The committee’s draft conclusions recommended two major changes to
Israel’s tax treatment of the oil and gas industry. First, the draft conclusions suggested eliminating
the existing depletion deduction.14 Second, a progressive tax on oil and gas profits was proposed.
In the proposal, profits were determined using the ratio of total revenues to total exploration and
development costs. The committee’s draft conclusions did not recommend a change in Israel’s
royalty rate, which is set at 12.5%.15
The committee’s final report was released on January 3, 2011 and fully accepted by Prime
Minister Netanyahu and the cabinet.16 Overall, the committee’s recommendations would increase
the government’s share on oil and gas revenues to between 52% and 62%, up from the current
30%.17 Like the draft conclusions, the committee’s final recommendations suggest eliminating the
depletion allowances and imposing a tax on oil and gas profits. The tax on profits would start
after the project had earned cumulative net income equal to 150% of its exploration and
development costs.18 The rate of tax would start at 20%, increasing to maximum rate of 50%.19
This tax increase would be phased in over time. Fields that start production prior to 2014—which
would likely include Tamar and possibly Dalit, but not Leviathan—would be partially exempt
from the tax increase. For reserves in which extraction begins by January 1, 2014, the profits tax
will not apply until cumulative net income reaches 200% of exploration and development costs
and will not be fully phased in until reaching 280%.
The tax increase recommended in the final report was less than was initially presented in the draft
proposal.20 The proposed tax increases will be enacted only if approved by the Israeli

Summary of the committee’s recommendation as well as secondary sources in the overview presented here. The

14 Depletion deductions allow taxpayers to account for a reduction in a product’s reserves. The deduction reduces
taxable income, thereby reducing tax liability. The commission’s draft conclusions provided a rationale for eliminating
the depletion deduction. The commission noted that the depletion deduction was intended to compensate owners of
mineral assets for the asset’s reduced value following resource extraction. In the present case, the asset is owned by the
state. Thus, allowing depletion deductions does not compensate the asset owner (the state) for a reduction in asset
value.
15 For comparison, royalty payments in the United States are generally between 12.5% and 30% of the gross wellhead
value of production, depending on the lease contract.
16 The recommendations still need to be passed by Israel’s parliament before they take effect. See Netanyahu “fully
accepts” Sheshinski C’tee findin

Taxes on Oil and Gas Extraction Profits,” New York Times, January 23, 2011.
17 Guy Chazan, “Israel Sets Steep Rise in Taxes on Oil, Gas,” The Wall Street Journal, January 4, 2010.
18 Net cumulative income is defined as cumulative income less project expenses, royalty payments, and profits taxes
paid in previous years.
19 The 50% rate would be applied once the ratio of net cumulative income to exploration and development costs
reaches 230%.
20 The draft proposal would have imposed a 60% to 70% tax on earnings above 150% of a company’s investment.

government. Israeli and U.S. companies oppose any tax increase, and argue that changing the tax
regime will deter future energy resource development.21
Comparison to U.S. Energy Tax Policy22
Oil and gas producers in the United States pay the U.S. corporate income tax. The corporate tax is
levied on taxable income, which is calculated as gross income less deductions. The statutory
corporate income tax rate is generally 35%. There are a number of deductions specific to the oil
and gas industry, such as the ability to expense intangible drilling costs (IDCs) and to claim
percentage depletion instead of cost depletion.23 Oil and gas producers are also eligible for the
Section 199 production activity deduction.24
The United States has generally not imposed a specific profits tax above and beyond the
corporate income tax on the oil and gas industry. However, from 1980 through 1988, the United
States levied a windfall profits tax (WPT) on the U.S. oil industry. In practice, the WPT was an
excise tax.25 The tax was determined according to the price of oil rather than on profits. The WPT
was enacted to address increased oil industry profits following the decontrolling of oil prices.26
Lebanon Contests Discoveries
The announcements by Israel and Noble Energy of significant natural gas discoveries have
prompted Lebanese leaders to raise concerns that the natural gas fields are at least partially in
Lebanese waters and that Israel will “steal” Lebanon’s resources if the Lebanese government does
not act. Lebanon and Israel have never defined their maritime border as the two countries are still
technically at war. The Lebanese government has appealed to the United Nations, particularly the
UN Interim Force in Lebanon, to intervene in defining the maritime border, but the UN has
declined thus far to delineate the maritime border.27 Some trade press for the natural gas industry
is depicting all the Noble Energy discoveries within Israeli borders.28
There has been rhetoric from both the Lebanese and Israeli governments about using all means
necessary, including military action, to defend their national resources, according to regional
press reports.29

22 Comparison to U.S. energy taxes was provided by Molly Sherlock of CRS.
23 Cost depletion allows for the recovery of the actual capital investment. With cost depletion, total deductions cannot
exceed the original capital investment. Under percentage depletion, the deduction for recovery of a capital investment
is a percentage of the “gross income”—that is, revenue—from the sale of the mineral. With percentage depletion, total
deductions may exceed the initial capital investment.
24 Internal Revenue Code (IRC) § 199 allows domestic manufacturers to take a deduction from net income. Most
manufacturers are allowed a deduction of 9%. Oil and gas producers are allowed a reduced deduction of 6%.
25 Excise taxes are typically imposed on a transaction, rather than on a person or corporation. Excise taxes can be levied
on a per-unit basis or ad valorem basis.

Prospects for the Future
Export Potential Possible
Whether Israel will become an exporter of natural gas is yet to be determined. If the resource
estimates are correct, the new fields would give Israel the resources to become an exporter. A
number of factors raise doubts about the viability of exports: Growing domestic demand—and
potential new uses for gas, energy security issues, the expense of liquefying the natural gas for
transport, an existing global glut of natural gas, and the politics of pipeline exports. Noble Energy
is exploring the possibility of building a liquefaction facility, possibly in Cyprus to utilize any
natural gas discovered there, for exports to Europe and Asia, but it is too early to determine the
feasibility of such a project.
Other Regional Natural Gas Development Likely
Hoping to replicate Israel’s success in finding new energy resources, Cyprus, Lebanon, and Syria
have announced timetables for holding auctions for licenses to explore for oil and gas. Cyprus
and Syria plan to hold their license auctions this year, while Lebanon has theirs scheduled for
2012.30 It is unclear how the ongoing political deadlock might affect the Lebanese government’s
plans to move forward with its energy development.31 In December 2010, Cyprus and Israel
signed an agreement defining their sea border.
In March 2010, The U.S. Geological Survey (USGS) released a report on the Levant Basin
province that stretches from the Sinai peninsula to the northern border of Syria and from the coast
into the Mediterranean Sea to the western side of Cyprus. The report stated that the Levant Basin
may hold 1.7 billion barrels of recoverable oil and 122 trillion cubic feet of recoverable natural
gas.32
Oil Discoveries Possible
In light of the USGS report, Noble Energy and its partners have raised the prospect of drilling
deeper, below the natural gas bearing formations in the Leviathan field in search of oil. Noble
Energy estimates that there is a 17% probability that it could find 3 billion barrels of oil.33 The
probability and estimate will likely change as additional information and data is gathered.

Israel’s Offshore Natural Gas Discoveries Enhance Its Economic and Energy Outlook

Policy Considerations
The U.S. government34 is not directly involved in Israel’s oil and gas policies. However, in the
near-term, consultations regarding the energy policy and regulations would be one area that
government to government interaction might take place. Israel has never been a major energy
producer and must balance its normal economic and security concerns with development of this
new resource. The United States has experience related to regulatory oversight, tax policy, and
environmental concerns that could benefit Israel.
The regional interest from other countries to develop energy resources creates an opportunity for
discussions between Israel and its neighbors, bilaterally or multilaterally and directly or
indirectly. Additionally, resolving the maritime demarcation issue between Israel and Lebanon
would alleviate industry uncertainty.
