Project Name :

Appraisal and Development Operations of South Pars Oil Layer Project

Location :

The South Pars Oil Field is located in the center of Persian Gulf on the Qatar-Fars high, about 100 km from Iranian coast, and adjacent to the international boundary with Qatar.

Scope of work :

• Collecting, certifying and interpreting data, preparing reservoir models, and proposing the strategy for optimum development of the field.
• Drilling and completing 6 new horizontal wells ( 3 multilaterals and 3 single producers ).
• Drilling  and extending the open hole section of the existing well.
• Construction of a wellhead platform.
• Providing production facilities including Floating Production Storage and Offloading (FPSO) vessel, mooring system and flexible pipe to transfer crude oil from wellhead platform to the FPSO vessel.  

Objectives :

• Production of up to 35,000 bpd of crude oil in the 1st development phase.
• Evaluating production enhancement of the field, and identifying new producing layers.
• Appraising the field and evaluating the possibility of the 2nd phase development.

Achievements:

Status: 30.5% physical progress (including the additional works and updating the weight factors for calculating project progress)

·         Sub-surface Studies

o        Updated production forecast based on reservoir model updates using information obtained from drilling.

o        Full field reservoir static and dynamic models were developed and later revised with latest available data.

o        Finalized depth structure map of reservoirs

·         Drilling Operations  

o       Drilling six new wells through the sub sea drilling template

o       Compiling completion and drilling equipment list required for the tie-back and completion operation

o        Preparing preliminary drilling schedule for completion phase.

·         Offshore  surface facilities

o        The engineering design contract for the W.H.Platform was awarded to a contractor(Tecnomare) and the work was completed on December 2006.

o        The received proposals of FPSO Providers are under evaluation and discussion.

o        The platform's jacket fabrication was started by WHP ePCI contractor (SAFF).

o        The pipeline engineering is completed.
