Development of Dorood Oil Field

Development of Dorood Oil Field
Executive Activities
The implementation work consists of drilling of 29 new wells which include 15 production wells, 12 water injection wells and 2 gas injection wells. Injection of water and gas to reservoir is planned to achieve the maximum possible incremental oil production.
Major equipment and facilities include:
Gas treatment unit, gas dehydration unit, water injection unit, gas injection unit, turbo generators, installation of an offshore platform and pipe lines onshore and offshore between clusters and new plant.
Location
The Dorood field is located in the northern part of the Persian Gulf, The field partly underlies Kharg Island.
Basic Contractor
TOTAL FINAL ELF (%55)
AGIP Iran (%45)
Project Schedule
Effective date: March 1999
Finesh date: February 2006
 










Development of Dorood Oil Field


Dorood has an estimated oil-in-place and recoverable reserve of 7.6 billion and 1.5 billion


THE HISTORY OF THE FIELD


The Dorood field was discovered in 1961 with the IPAC exploration well Darius-1 (D-1) drilled offshore. Oil production started in 1964. Before the start of the drilling campaign operated by ELF petroleum Iran, 49 wells drilled on the Dorood field.


 THE TECHNICAL CHARACTRISTICS OF THE FIELD


The Dorood field follows a N-NE to S-SW elongated anticline approximately 25 km long by 5 km wide.


The main productive horizon is represented by the FAHLYAN limestone formation which results from deposits on a carbonated platform from the Neocomian (Lower cretaceous) geological stage. The ultimate recoverable Oil reserve is estimated to be around 2.5 MMM STB which will be achieved by water injection rate of 250 MBPD and Gas injection rate of 120 MMSCFPD. Considering the 7.6 billion barrels of Oil in place, the recovery factor will be approximately 31% by the year 2030.


JOB OPPORTUNITIES




  • NIDC 95 persons on two drilling units.


  • IOOC 136 persons during production phase.


PROVATE SECTOR


More than 2000 Iranian staff or workers in the region during construction phase were emplyed.


IRANIAN CONTENT


About 30 percent of CAPEX has been allocated to Iranian content, but approximately 42% of CAPEX has been committed in Iranian sectors which, in turn, results in promotion of ability of internal companies.


TRAINING AND TECHNOLOGY TRANSFER


The contractor has been obliged to spend 1 percent of CAPEX (5.4 MM) for training and technology transfer in order to enable the Iranian personnel to handle the Dorood field operation. To accomplish the aforesaid objectives, various training sessions, both in Iran and abroad, were established.


A total of 307 IOOCs personnel participated in various training courses in England, Italy, France and Iran in different training stages.
