MARGHAM FIELD

     


The Margham Gas Field located approximately 55 Km from Dubai off the Dubai/Hatta road, is the largest gas field onshore Dubai. The field contains three gas-bearing geological formations, Shuaiba, Kharaib and Lekhwair, which are fractured limestone layers located more than 10,000 feet below the surface.

The field opened in 1984 and has been developed with several production and injection gas wells that are connected through a gathering system to the Margham Plant, which occupies a 60 acre site. Raw gas is processed in the Plant to recover condensate for sale and the residual dry gas reinjected to maintain pressure in the underground formation or transported via pipeline to Jebel Ali users.

The raw gas enters the Margham Plant through a manifold and by a series of cooling, pressure reduction, and phase separation steps, the heavier hydrocarbon components and formation water are separated.

The raw condensate is brought to product specification by further removal of water and stabilized by distillation. The residual gas stream, substantially free of liquid components, is repressured in two multi-stage, gas turbine driven centrifugal compressor trains and reinjected into the formation through six wells.

Returning the gas to the reservoir conserves this product for future use and increases the ultimate recovery of liquids from the reservoir formation. The stabilized condensate product is moved by gravity through a pipeline to a coastal terminal at Jebel Ali. At the terminal, the product is held in two storage tanks. The terminal is equipped with high capacity pumps to enable the transfer of feedstock for further processing or alternately the export of condensate to tankers via a dockside-loading arm.

Over the years, some of the dry gas has been diverted from the compressor feed and exported for Jebel Ali utilities use. In 2007 a decision was made to use the Margham field as a dry gas storage facility, and since 1st January 2008, DUSUP has been storing imported gas bought under long-term contractual arrangements during the winter months. This stored gas has then been re-exported from Margham during the hot summer months, when utility demand in Dubai is at its highest. By using Margham as a storage facility, Dubai has managed to reduce to zero the amount of oil products burnt for electricity generation (other than for the occasional operational reason), with an important environmental benefit seen through the reduction of air pollutants.

By using Margham as a strategic storage facility, DUSUP will extend the life of this key piece of Dubai energy infrastructure for many years to come.

PIPELINE DEPARTMENT

       

The Pipeline Department designs, constructs, operates and maintains DUSUP’s onshore pipelines and related facilities to International Standards in order to ensure an uninterrupted flow of gas and other hydrocarbons across Dubai for our own supplies and imports from other countries. The pipeline network covers 460kms, and ranges from 48" high pressure gas pipelines down to 10" condensate lines.

The Pipeline Department also operates a No Objection Certificate (NOC) system across the Emirate of Dubai whereby any contractor or developer working near a pipeline must provide the details of their work plan for technical review and approval. This is to keep Dubai’s pipeline infrastructure safe and in harmony with the construction and development activities across the Emirate.

Pipeline Department inspectors monitor all work near pipelines and patrol the entire pipeline system on a twice daily basis. As an additional safety measure to protect against third party encroachment, warning signs have been installed at 250 meter intervals along each pipeline for the entire route.
DUBAI LNG

     

As Dubai grows, so the demand for energy grows. DUSUP supports the growth of Dubai by ensuring that it buys sufficient energy at competitive price to secure the future of the Emirate. Whilst today DUSUP buys the majority of its pipeline gas from Abu Dhabi and Qatar, for the future DUSUP continues to seek out new sources of energy from around the world; to diversify its supply and to manage the growth in energy demand especially during the peak summer period. The development of the DUSUP LNG terminal has been a key element of that diversification goal.

At the end of 2010 DUSUP completed the construction of a Liquefied Natural Gas (LNG) Import Terminal in Jebel Ali port which allows the import of LNG via a Floating Storage Regasification Unit (FSRU), the “Golar Freeze”. The Golar Freeze was an LNG tanker specially converted into an FSRU for this purpose and it is permanently moored at the Terminal. LNG tankers berth alongside the FSRU and discharge LNG into the FSRU. The FSRU warms the liquefied gas back to its gaseous state using seawater through a heat exchanger, and then flows the gas into the onshore pipeline network.

DUSUP buys LNG both on the basis of a long term agreement for supply and by purchasing LNG spot cargoes to support short term changes in demand. The combination of DUSUP’s FSRU terminal and Margham gas storage facility makes it possible for DUSUP’s LNG trading team to respond to spot market opportunities at short notice. DUSUP has received a wide range of LNG specifications and has sourced the gas from all the major LNG exporting countries taking delivery from as far away as Trinidad and Australia. DUSUP conducts regular programme Ship terminal compatability reviews and has a wide range of LNG carriers approved for the terminal including a good safe track record of deliveries of different carrier sizes up to and including the Q-Flex class.

TRANSPORTING GAS

DUSUP also plays a key role in transporting gas from Qatar into the Northern Emirates. DUSUP manages the transportation of this gas through its pipeline network from the Dubai/Abu Dhabi border to the Dubai/Sharjah border to meet the needs of the Sharjah Electricity & Water Authority (SEWA) and the Federal Electricity & Water Authority (FEWA).
