Block 61 among world largest tight gas development
In January 2013, BP received the technical and commercial offers from the engineering companies bidding on the key packages of its Block 61 tight gas full field development phase-1 project in the Sultanate of Oman.
Last September, BP had announced to scale up its capital expenditure from $15 billion to $24 billion to develop and turn the complex fields such as Khazzam and Makarem of the Block 61 into production.
Discovered in the 1990s, by 4,500 to 5,000 meters depth, this field is made of four main reservoirs, including Khazzam and Makarem, estimated to contain 20 to 30 trillion cubic feet (tcf) of natural gas.
Immediately in following Global Geophysical Services and PGS Data Processing ME performed an intensive campaign of 3D seismic data acquisition to detail the field and confirm its potential reserves.
In 2011, BP performed successfully the first horizontal well with hydraulic fracturing technique.
From these first tests BP awarded the pre-front end engineering and design (pre-FEED) and FEED work to WorleyParsons Oman to designed its Oman Full Field Development phase-1 program to produce 1 billion cf/d of natural gas during 25 years.
This soft water is loaded with chemical products to facilitate the gas mobility in the reservoir.
At the production well, this water is separated from the gas and requires a waste treatment by desalination.
Four bidders for Saih Rawl gas central processing plant
Therefore the BP Oman full Field Development phase-1 project has been designed with:
– Well testing facilities
– 500 kilometers of flowlines
– Central Processing facilities
– Gas processing plant with 1.2 billion cf/d capacity
– 100 kilometers export gas pipeline
– Waste water treatment facility
– Flowlines, Central processing facilities, gas central processing plant, export pipeline and associated facilities
– Early development phase, gas gathering, wellsides and export system (GWES) facilities, building and infrastructures work
Four teams of engineering companies submitted an offer for the first EPC package:
– Bechtel from USA with Bahwan Engineering Company from Oman
– CB&I from USA with Larsen & Toubro from India
– Petrofac from UK with Consolidated Contractors Company (CCC) from Greece
– Technip from France with Galfar Engineering & Contracting and Al-Hassan Engineering Company and Special Technical Service, all three from Oman
Three bidders returned offers for the second EPC package:
– Bechtel from USA
– Carillion Alawi from UK and Oman
– WorleyParsons Oman
With these technical and commercial bids submitted, BP is ready to go for this Oman Full Field Development phase-1 considering that the phase-2 should be mostly concentrated on the expansion of the drilling operations and multiplication of the production wells of this Block 61 tight gas.
