WDDM Development Project

WDDM Development Project 
Office: Europe/ Africa 
Customer: Burullus Gas Company 
Location: Mediterranean Sea 
Timeframe: 2000 - Ongoing 
The West Delta Deep Marine (WDDM) concession offshore Egypt in the Mediterranean Sea directly abuts the existing shallow-water operations in the Rosetta concession, with the concession line closely following the 656 ft (200 m) seabed contour. Developments are located in water ranging from about 984 ft (300 m) to 3,937 ft (1,200 m) deep, hence the diverless subsea technology used was selected from applications in the Gulf of Mexico and North Sea. The first development phase was dedicated to the Egyptian market, but the main pipeline’s core infrastructure-from the Pipeline End Manifold (PLEM) to receiving facilities onshore-was designed to allow for expansion. Subsequent phases were dedicated to a new LNG plant built at Idku, near Alexandria, and connected through expansion connections provided in the PLEM hub location.


INTECSEA performed the concept definition studies and the subsequent FEED phases including the detailed flow assurance work for the project. Activities included feasibility studies to determine the best field architecture, flow assurance, pipelines, subsea hardware and control system. The initial developments included provision for future tie-in of wells and manifolds to the existing manifolds and expansion of the existing control system. Burullus Gas also created a team of subsea specialists consisting of Burullus Gas personnel and INTECSEA engineers to oversee the technical aspects of the EPIC contract from invitation to tender until first gas.

INTECSEA has continually worked alongside Burullus Gas through nine phases of field development and expansion. The initial eight wells in the development have grown to 40 wells today, with the possible expansion of more than 30 plus wells in the future.

INTECSEA has been responsible for the conceptual design, front-end engineering design (FEED) and the technical assurance for all phases of the WDDM development to date.

Project Highlights

  • Burullus maintains continued production at required rates
  • INTECSEA provide a continued project history, being involved since inception in 2000
  • First gas dates achieved early on phase IV
  • Field expansion successfully achieved beyond initial design expectations
  • Value added by optimizing designs such that production shutdowns were minimized during field expansion operations
