The Abu Dhabi Gas Industries (Gasco) has shortlisted four bidders for the third phase of the Onshore Gas Development (OGD-3), valued at Dh4.77 billion ($1.3 billion), said its top official.

They are France's Technip, Bechtel of the US, Chiyoda Corp and JGC of Japan. The bids are currently being evaluated and an engineering, procurement and construction (EPC) contract will be announced shortly.

Mohammad A. Sahoo, Gasco's general manager, said: "We have already narrowed down the technical and legal issues with the bidders, after thorough negotioations.

"We will award the contract in a few weeks' time, hopefully during Ramadan, once the negotiations and formalities are completed."

This is part of the three projects that are in the tendering phase, other being Ruwais NGL 3rd Train project, valued at $1 billion and phase two of Asab Gas Development (AGD-2) project, valued at $700 million, he said.

Besides, Gasco has also issued a tender for a $600 million expansion project involving the construction of gas injection compressor/feed compressor at Habshan.

"The completion of these projects will increase the total capacity of our production from the current 5 billion standard cubic feet per day (scfpd) to 8 billion scfpd," he told over 200 officials and businessmen at a two-day conference on Major New Projects Opportunities in Dbu Dhabi.

"Besides, we are also floating a new tender for an additional gas train in Habshan later this year for a possible contract during the third quarter of next year.

"In addition, we are undertaking some upgradation projects in some of the existing facilities including Bu Hasa facilities, Habshan ethane recovery maximisation, Habshan capacity enhancement, Bu Hasa integrated control system, pipeline network extensions and storage capacities, the total value of which would be over $200 million," he added.

By 2008, Gasco will increase its supply of ethane from the current level of 2,500 tonnes per day (tpd) to 8,000 tpd.
