NSAI Report Upgrades Leviathan Gas Reserve Estimates
Type: Operator Update

Jul. 2014 - The estimated size of gas reserves at the Noble Energy-operated Leviathan field offshore Israel has been increased based on a recent study completed by Netherland Sewell & Associates, Inc. (NSAI). The prior low estimate of 14.89 Tcf is now 16.58 Tcf which represents and 11% increase. Similarly, the high estimate has been increased by 10% to 26.52 Tcf. The increase of reported reserves is a result of re-processing and re-analysis of 3D seismic data and a series of tests reservoir rock and fluids. Delek Drilling says the higher reserves will help ensure Israel's energy independence for decades to come.

Woodside Elects to Back Out of Recently Signed Leviathan MoU
Type: Operator Update

May. 2014 - In February 2014, the partners in the Leviathan gas development offshore Israel signed a non-binding memorandum of understanding (MoU) that would allow Australia's Woodside to acquire a 25% participating interest in the 349/Rachel and 350/Amit licenses. Woodside recently advised the partners of its intention to terminate the MoU citing the group's inability to reach a commercially acceptable agreement that would allow fully-termed agreements to be executed. Operator Noble Energy and the other participants will proceed with their goal of sanction Phase 1 of the development by the end of the year. Phase 1 will consist of subsea wells tied to an FPSO capable of producing gas at a rate of 1.6 Bcf per day.

Leviathan Partners Agree on MoU for Woodside Farm-In
Type: Acreage Acquisition

Feb. 2014 - Noble Energy and the Leviathan development partners signed a memorandum of understanding (MoU) to allow Woodside Petroleum to acquire a 25% interest in the 349 Rachel and 350 Amit licenses. Leviathan covers portions of each license and is estimated to hold 2C contingent gas resources of 18.9 Tcf along with 34.1 million barrels of condensate. The MoU includes the agreed-upon commercial terms of the transaction and sets the timeframe for the execution of definitive agreements. Execution of the definitive agreements and regulatory approval are needed for completion of the contract. If approved, Woodside will become the operator of any LNG development of the field with Noble remaining operator of all upstream activities. The joint venture partners will consist of Noble Energy (30%), Woodside (25%), Delek Drilling (16.94%), Avner Oil (16.94%) and Ration Oil (11.12%).

Woodside Close To Leviathan Deal
Type: Operator Update

Dec. 2012 - An agreement has been reached between Woodside and the partners of the Leviathan natural gas field whereby Woodside will acquire a 30 percent interest and become operator of any LNG development associated with the field. Leviathan lies in the offshore 349/Rachel and 350/Amit blocks and is thought to contain roughly 17 trillion cubic feet of recoverable natural gas. The agreement has not been finalized and will be subjected to the necessary government and regulatory approvals. If approved, Woodside will be subject to an initial payment of $696 million and will carry the cost of a deep exploration well targeted for late 2013.

Leviathan Licensees Seeking Additional Partner
Type: Operator Update

Oct. 2012 - The partners in the Leviathan gas field offshore Israel are taking bids to add an international partner to the group to help distribute field development costs. Being offered is up to a 30% stake in the field. Sources indicate Australia's Woodside Petroleum and Russia's Gazprom are likely finalists in the bidding round. Leviathan holds an estimated 17 trillion cubic feet of gas and is expected to be brought into production in 2017. The bidding round is due to end in the coming month.

Noble Moves Forward with Putting Leviathan 2 to Bed
Type: Operator Update

Aug. 2012 - Noble Mediterranean Energy along with external consulting firms and the Israeli Department of Energy and Water have selected an alternate plan for sealing and abandoning drilling operations in Leviathan 2 offshore Israel. Drilling will be carried out by the ENSCO 5006 (DW semisub) for an estimated period of 60 days at a cost of $46.6 million. However, due to the complexity of the plan, deviations to these estimates are likely. Noble, the field operator, does not expect any environmental damage to result from the abundance of water produced from Leviathan drilling operations.

Noble Suspends Leviathan Drilling Ops
Type: Drilling Operations

May. 2012 - Noble Energy announced that the Leviathan deep well offshore Israel has reached a depth of approximately 21,400 feet (6,523 meters), the deepest known penetration in the Levant Basin. High well pressure and the mechanical limits of the wellbore design resulted in the suspension of drilling operations before the primary objective was reached. Over the course of deepening the Leviathan No. 1 well, the operator obtained valuable geologic and engineering data about the basin. At approximately 21,000 feet (6,401 meters), the well encountered a zone where natural gas was detected. The composition of the natural gas was heavier than discovered in the shallower intervals and suggests a thermogenic source. At a total depth of 21,400 feet (6,523 meters) higher pressure was encountered indicating the possibility of an overlying seal. The Noble Homer Ferrington (mid-water semisub) is scheduled to remain on location at the No.1 well to conduct a production flow test of the previously discovered natural gas sands at Leviathan

Drilling Recommences at Leviathan-1
Type: Status Update

Jan. 2012 - Noble Energy has recommenced drilling at the Leviathan prospect. The Homer Ferrington (DW semisub) has arrived on location in the Rachel license drilling site and is expected to drill into the deeper targets of the well in the coming days. Drilling will continue where it left off in April 2011 for technical and operational reasons as reported in the past. Drilling is expected to last for three months. The Leviathan prospect is located in 5,361 feet (1,634 meters) of water at the Rachel and Amit license offshore Israel.

Noble Energy Revises Drilling Schedule
Type: Status Update

Sep. 2011 - Noble Energy stated that the ENSCO 5006 semisub, which has experience technical difficulties while drilling, will move off the Leviathan No. 3 well to undergo repairs to the rig's riser system. Once repairs area completed, the rig will mobilize to the Dolphin prospect. The operator will then mobilize the Sedco Express semisub to the Leviathan No. 3 location to conclude drilling operations. The rig will then drill up to two exploration prospects before returning to Tamar to finish development drilling and perform completion work. According to Noble's estimates, the Leviathan-3 drilling work is expected to be completed by mid-November 2011.

Noble Energy Updates Drilling Ops at Leviathan 2 well
Type: Status Update

May. 2011 - Noble Energy has decided to end drilling activities on the Leviathan-2 well off Israel after water was discovered flowing up to the wellbore to the sea floor. Noble plans to move its drilling rig to another location to drill an alternate appraisal well. While conducting appraisal drilling, a flow of water was identified in the well hole but did not indicate hydrocarbons. Noble said it has concluded that the current location and wellbore are unsuitable for continued drilling, and will move the rig to a new location to resume drilling operations. Drilling of the new well will commence within a month and should last for about three months. The Leviathan prospect is located in 5,361 feet (1,634 meters) of water offshore Israel in the Rachel and Amit license. Noble Energy operates the license, holding a 39.6% interest; Ratio Oil Exploration 1992 LP holds 15%; Delek Drilling LP holds 22.7%; and Avner Oil and Gas Ltd. holds 22.7% interest.

Noble Halts Drilling Ops Offshore Israel
Type: Status Update

Apr. 2011 - Noble Energy has suspended drilling operations at the Leviathan No. 1 well location, which was testing deeper potential in the well. Noble identified wear on the wellbore casing, requiring additional material and equipment necessary to complete the drilling of the well. The company is working to secure the needed items, which are not available in Israel. Because of this, Noble is preparing to move the Sedco Express semisub to the Tamar field, where development drilling is anticipated to begin in about a week. The development of the Tamar field remains on schedule for commissioning in late 2012. Both fields are located offshore Israel.

Noble Hits Big in Leviathan Discovery
Type: New Discovery

Jan. 2011 - Noble Energy has confirmed a significant natural gas discovery at the Leviathan prospect offshore Israel. The well encountered a minimum of 220 feet (67 meters) of natural gas pay in several subsalt Miocene intervals. The operator says reservoir quality is very good, and the intervals discovered are geologically similar to those intersected at Tamar. Thus far, results are in line with the pre-drill estimated resource range, with a gross mean for Leviathan of 16 Tcf. The Leviathan field is estimated to cover about 125 square miles, and because of its size, will require two or more appraisal wells to further define its total gas resources. Chairman and CEO Charles D. Davidson commented, "Leviathan is the latest major discovery for Noble and is easily the largest exploration discovery in our history." Drilling at Leviathan-1 will continue to a planned total depth of 23,600 feet (7,193 meters) to evaluate two further intervals. Currently, the well is at a depth of 16,960 feet (5,169 meters). A second rig will arrive in the Eastern Mediterranean in early 2011 to spud an appraisal well, about 8 miles (13 kilometers) northeast of the discovery well. Noble Energy operates the license, holding a 39.7% interest; Ratio Oil Exploration 1992 LP holds 15%; Delek Drilling LP holds 22.7%; and Avner Oil and Gas Ltd. holds 22.7% interest.

Noble Expects Testing Delay at Leviathan
Type: Status Update

Dec. 2010 - Noble Energy, operator of the Leviathan-1 well, is expecting a delay in completing the various inspections, including the electrical tests of the main layer. The tests should be completed by year-end. The Leviathan prospect is located in 5,361 feet (1,634 meters) of water offshore Israel in the Rachel and Amit license. Noble Energy operates the license, holding a 39.7% interest; Ratio Oil Exploration 1992 LP holds 15%; Delek Drilling LP holds 22.7%; and Avner Oil and Gas Ltd. holds 22.7% interest.

Noble Energy Spies Natural Gas in Leviathan-1 Well
Type: Drilling Operations

Nov. 2010 - Noble Energy reported that the Leviathan-1 well has penetrated the first interval in the primary objective. Based on information gathered while drilling, it seems that natural gas was encountered in the primary target. Drilling will continue by the Sedco Express semisub, and once completed, a full well evaluation will be conducted. The Leviathan-1 well is a gas target located in Tertiary-Oligocene age sands at a depth of 16,716 feet (5,095 meters). It is estimated the prospect contains about 16 Tcf of unrisked mean resource potential of natural gas. The Leviathan prospect is located in 5,361 feet (1,634 meters) of water offshore Israel in the Rachel and Amit license. Noble Energy operates the license, holding a 39.7% interest; Ratio Oil Exploration 1992 LP holds 15%; Delek Drilling LP holds 22.7%; and Avner Oil and Gas Ltd. holds 22.7% interest.

Type: Drilling Operations

Oct. 2010 - The Sedco Express semisub has arrived at the drill site of the Leviathan-1 well in the Rachel license and began drilling, announced Noble Energy. The well should take about five months to complete. The Leviathan-1 well is a gas target located in Tertiary-Oligocene age sands at a depth of 16,716 feet (5,095 meters). It is estimated the prospect contains about 16 Tcf of unrisked mean resource potential of natural gas. The Leviathan prospect is located in 5,361 feet (1,634 meters) of water offshore Israel in the Rachel and Amit license. Noble Energy operates the license, holding a 39.7% interest; Ratio Oil Exploration 1992 LP holds 15%; Delek Drilling LP holds 22.7%; and Avner Oil and Gas Ltd. holds 22.7% interest.

Noble Plans to Spud Leviathan Well in October
Type: Drilling Operations

Aug. 2010 - Noble Energy and partners plan to drill the Leviathan-1 well in the Rachel license in October 2010 using the Sedco Express drilling rig. The well, situated in a water depth of 5,361 feet (1,634 meters), will be the deepest well ever drilled off the coast of Israel. Since there is limited data about pressure, reservoir and hydrocarbon source conditions at the depths of the secondary targets, the rig may be replaced during drilling of the deeper section with the Pride North America. Once drilling is completed and if a discovery is made, the Pride North America will perform a production test of the well. The Leviathan-1 well is a gas target located in Tertiary-Oligocene age sands at a depth of 16,716 feet (5,095 meters). It is estimated the prospect contains about 16 Tcf of unrisked mean resource potential of natural gas.
