Delek outlines scenarios for deepwater Leviathan project offshore Israel

Offshore staff

TEL AVIV, IsraelNoble Energy and its partners have submitted a revised development plan for the deepwater Leviathan gas/condensate field to Israel’s Ministry of National Infrastructures, Energy and Water Resources.

According to Delek Group, parent company of two of the partners - Avner Oil Exploration and Delek Drilling - the plan calls for eight production wells, two of which are already drilled and which will be completed for production.

These will be connected by a subsea pipeline to a fixed platform housing all gas treatment systems. Processed gas will be transported to a connection point to the Israel National Gas Lines (INGL) onshore transportation grid.

Collectively, the facilities will accommodate throughput of around 21 bcm/yr, up from 16 bcm/yr in the earlier plan.

In addition, the platform will feature a connection for an additional subsea pipeline with a capacity of up to 12 bcm/yr, mainly intended for export to neighboring countries.

Preliminary estimates suggest an overall cost of $5-6 billion, down from $6-7 billion previously.

There is also scope for a two-phase development, the first phase of which would involve four wells (including the existing ones recompleted for production), and installation of the platform with  treatment facilities providing capacity of up to 12 bcm/yr. Delek estimates the cost at $ 3.5-4 billion.

Under a second phase, four additional wells would be drilled and the platform’s treatment capacity raised by an additional 9 bcm annually.

To fully exploit the resources of the Leviathan reservoir during the lifespan of the project, many more production wells will likely be needed, Delek points out.

The partners intend to advance the process of securing regulatory approvals and executing gas sales agreements to allow a final investment decision on the development to be taken in 4Q 2016. This would lead to first gas in 4Q 2019.

Should the scope of demand for gas increase beyond the capacity of the defined production system, the partners will incorporate additional treatment facilities not currently included in the development plan and a further development phase targeting other markets such as the Turkish sector.

The partners in the Leviathan project and their interests are as follows:

Noble Energy Mediterranean                                    


Delek Drilling - Limited Partnership                                            


Avner Oil Exploration - Limited Partnership                                  


Ratio Oil Exploration (1992) - Limited Partnership
