Project Description
The West Delta Deep Marine Concession is situated roughly 56 miles (90 kilometers) from the Nile Delta shoreline in water depths of 820 to 2,789 feet (250 to 850 meters). The natural gas project is estimated to contain reserves in the amount of 4 Tcf and is the first deepwater venture of its kind in the Eastern Mediterranean.

The Burullus Gas Company developed the fields, which is a joint venture between Egyptian General Petroleum Company, BG Egypt and Petronas. Since the concession agreement was finalized in 1995 for the development of the project, four 3D seismic surveys have been acquired, processed and interpreted in the WDDM concession.

The first well to be drilled was Scarab-1, testing in excess of 30 MMcf/d (.85 MMcm/d), followed by the second well, ...
The West Delta Deep Marine Concession is situated roughly 56 miles (90 kilometers) from the Nile Delta shoreline in water depths of 820 to 2,789 feet (250 to 850 meters). The natural gas project is estimated to contain reserves in the amount of 4 Tcf and is the first deepwater venture of its kind in the Eastern Mediterranean.

The Burullus Gas Company developed the fields, which is a joint venture between Egyptian General Petroleum Company, BG Egypt and Petronas. Since the concession agreement was finalized in 1995 for the development of the project, four 3D seismic surveys have been acquired, processed and interpreted in the WDDM concession.

The first well to be drilled was Scarab-1, testing in excess of 30 MMcf/d (.85 MMcm/d), followed by the second well, Saffron-1, testing at a rate of 90 MMcf/d (2.5 MMcm/d) in 1998. The well, Saffron-1, is one of the highest gas flow rates ever encountered and recorded in Egypt. Following the success of these two discoveries, the Scarab-2 and Saffron-2 appraisal wells were then drilled in July 1998 and March 1999, respectively.

Shortly after, the consortium discovered nine separate gas discoveries in the area, proving the area held sufficient gas reserves for a substantial project to be developed, in two phases. Providing a guide for the remainder of the fields' development, the Scarab and Saffron fields were the first to commence production on March 29, 2003.

The WDDM field development is considered to be one of the longest subsea tie-backs in the world and has set the precedent of how to develop multiple fields without using multiple facilities for production.

Six of the other discoveries, Simian, Sienna, Sapphire, Serpent, North Sequoia and Saurus, were discovered between 1999 and 2001 and the fields came online in 2005. From 1998 to 2005, 28 exploration, appraisal and development wells have been drilled in the concession.

Field Development

The development of these two fields consist of 8 vertical wells, situated in 2,297 feet (700 meters) of water, connected to two subsea manifolds via a 10-inch-diameter flowline that is then connected to an onshore terminal, Idku, by two gas pipelines. Each manifold hosts four wells and incorporates a cross over spool linking the two manifolds; two 20-inch-diameter export lines link the manifolds to a pipeline end manifold located in 312 feet (95 meters) of water.

Field operations are controlled from the onshore terminal via electrical and hydraulic umbilical lines. Idku delivers up to 750 MMcf/d (21.23 MMcm/d) and roughly 3,000 barrels per day of condensate - treated gas is then transported to the Egyptian National Transmission System.

Cameron received a contract in 2001 for the engineering, manufacturing and testing of deepwater subsea production equipment for the Scarab and Saffron fields. The scope of work included management, engineering and supply of wellheads, Christmas trees, manifolds, control systems, connection systems intervention equipment, integration testing and installation support.

Following the subsea completion of the Scarab and Saffron fields, the next two fields to come online were Simian and Sienna, located northeast of the Scarab Saffron fields and 71 miles (114 kilometers) offshore Idku. The field development for the Simian and Sienna fields consisted of six-subsea production wells, four in Simian and two in Sienna in water depths of 2,221 to 3,258 feet (677 to 993 meters). The fields commenced production in 2005.

Subsequently, the Sapphire field commenced production in 2006. On the Sapphire field, eight production wells, ranging in water depths of 1,168 to 1,637 feet (356 to 499 meters), were tied-back to the additional manifolds that are then connected to the existing pipeline.

Further Development

The WDDM Concession is still being developed and additional fields will come online to add to the area's daily production.

Saipem to Install Subsea Equipment for West Delta Deep Marine Project
Type: Contract Award

Jun. 2011 - Burullus Gas Company awarded Saipem an EPIC contract for a new subsea development in the West Delta Deep Marine Concession. The development encompasses the engineering, procurement, construction and installation of seven new subsea wellheads, umbilicals and flowlines. The subsea work will connect to existing infrastructure. Offshore activities are set to begin in 2012. The West Delta Deep Marine Concession is situated roughly 56 miles (90 kilometers) from the Nile Delta shoreline in water depths of 820 to 2,789 feet (250 to 850 meters). The Burullus Gas Company developed the fields, which is a joint venture between Egyptian General Petroleum Company, BG Egypt and Petronas.

TDW Completes Subsea Hot Tap Tie-in for WDDM Project
Type: Pipeline Construction

May. 2011 - T.D. Williamson SA (TDW) has completed a subsea hot tap intervention operation to facilitate the successful tie-in of a new gas pipeline to an existing pipeline. The new pipeline forms part of the West Delta Deep Marine Phase VII development project in the Mediterranean Sea. The operation was performed for Technip Norge AS on behalf of the Burullus Gas Company, which required a tie-in of the new 36-inch-diameter gas export pipeline to an existing 26-inch gas export pipeline. The West Delta Deep Marine Concession is situated roughly 56 miles (90 kilometers) from the Nile Delta shoreline in water depths of 820 to 2,789 feet (250 to 850 meters). The Burullus Gas Company developed the fields, which is a joint venture between Egyptian General Petroleum Company, BG Egypt and Petronas.

Technip Awarded EPIC Contract for WDDM Project
Type: Contract Award

Jun. 2010 - Technip received an engineering, procurement, installation and construction contract from Burullus Gas for the West Delta Deep Marine Phase Villa development project. The project entails expanding the WDDM facilities, including: design, supply and installation of three production manifolds and three subsea distribution assemblies; engineering, welding and installing approximately 42 miles (67 kilometers) of rigid production flowlines; engineering, fabricating and installing about 55 miles (88 kilometers) of umbilicals, 7 miles (12 kilometers) of flexible flowlines and three flexible jumpers; connecting flowlines and umbilicals to the wellheads and subsea manifolds; and precommissioning of the entire system and support to the client for commissioning and start-up activities. The offshore campaign is scheduled to commence in the second quarter of 2011. The West Delta Deep Marine Concession is situated roughly 56 miles (90 kilometers) from the Nile Delta shoreline in water depths of 820 to 2,789 feet (250 to 850 meters).
