In this paper we will discuss optimization of completion solution in the South Pars field. By means of simplified completion methods, completion and testing time has been cut by more than 50% compared to the time spent on previous completions in the South Pars field.

We will discuss why we decided to change the "standard South Pars completion solution" commonly used by all other operators in the same field, and we will present the operational results from the first fourteen wells.


The South Pars field is located offshore Iran in the Persian Gulf. The field is divided into several phases, or offshore blocks, which are being developed in different stages over time (Figure 1). The allocated development area for phases 6, 7 & 8 comprise of three adjacent 10 km by 10 km blocks, in the centre of the Iranian sector, but on a crestal portion of the field.

In year 2000, Iranian oil company Petropars Ltd. was awarded the rights to develop Phases 6, 7 & 8 (SP 6-8) of the South Pars field. Two years later, in 2002, Norwegian oil company Statoil signed a Participation Agreement with Petropars Ltd., whereby Statoil became the technical operator for the three phases. Statoil's responsibility as operator covers the offshore part of the development, such as offshore pipelines, well head platforms, production topsides, and drilling and completion of the wells. The development is done in close cooperation with Pars Oil and Gas Company (POGC), which is responsible for the overall South Pars Field development on behalf of National Iranian Oil Company (NIOC).

As part of the Service Contract between Petropars and POGC, a Master Development Plan (MDP) was prepared. This MDP defines the scope of work for the development, and has also been the basis for all of the previous South Pars phases.

The development is based on unmanned well head platforms with connected bridges and flare platforms, which will be located centrally in each of the development blocks (Figure 2).
