Project Overview

• Engineering, Procurement, Construction and Commissioning of the Shadegan Oil Field

Scope of Work

• Full EPCC execution of surface facilities for field development
• Construction of oil transmission pipelines from Marun-3 Central Processing Facility (CPF) to Marun-4 CPF
• Pipeline installation from the Shadegan production cluster to Marun-3 CPF
• Installation of well flowlines, produced-water disposal systems, and expansion of the Shadegan production cluster

Project Objectives

• Comprehensive development of the Shadegan Oil Field to significantly increase crude oil production and enhance field recovery performance.

Shadegan Oil Field: Location, Characteristics & Development Outlook

• Strategic Location:

The Shadegan Oil Field is one of Iran’s major hydrocarbon assets, located in the southern part of Khuzestan Province near the city of Shadegan, approximately 65 km south of Ahvaz. Covering an area of about 138 km² (23 km long and 6 km wide), the field is situated between the Ahvaz oil field to the north and the Darkhoveyn oil field to the south, providing strong logistical and operational advantages.

• Reservoir Characteristics

The field comprises two primary reservoirs:

I. Asmari Reservoir:

Shallower depth, lighter crude, simpler production conditions, and higher production rates

II. Bangestan Reservoir:

Deeper formation with higher pressure, requiring more complex production techniques

Estimated oil in place reaches 4.4 billion barrels, with 400-500 million barrels considered recoverable using conventional technologies.

• Current Production Status

Currently operated by the National Iranian South Oilfields Company (NISOC), the field includes more than 30 drilled wells and produces 30,000–40,000 barrels per day. The development program aims to elevate production capacity to 150,000 barrels per day.

Development Strategy

Key Development Objectives:

• Increasing crude oil production capacity
• Deployment of Improved and Enhanced Oil Recovery (IOR/EOR) technologies
• Construction of surface facilities, including pipelines, booster stations, and processing units

Participating Companies

• Oil Design & Construction Company (ODCC)
• MA-Vostok (Russia)
• Taha Oil & Gas Development
• TAPPICO

These companies are executing the project under EPC-1 and EPC-2 contracts, covering full engineering, procurement, and construction scopes. The contracts were finalized in May 2024, marking a major step forward in the field’s large-scale development.

Crude Oil Quality

• Crude oil produced from the Shadegan field is generally classified as medium to heavy crude. In certain zones, sulfur content is relatively high, requiring additional processing or blending with lighter crudes for domestic consumption or export.

Strategic Significance of the Shadegan Oil Field

• Proximity to major oil infrastructure in Ahvaz and Darkhoveyn
• Strong potential to offset production decline in mature oil fields
• High appeal for international participation under Iran’s IPC contractual framework
• Collaboration with international partners such as MA-Vostok reflects Iran’s growing engagement with global expertise in upstream oil development
