Overview

SIST EN ISO 19008:2026 establishes a Standard Cost Coding System (SCCS) for the oil and gas industries, including lower carbon energy activities. Developed by the Slovenian Institute for Standardization (SIST), this standard provides a framework to classify costs, work hours, and quantities for assets and operations throughout all asset life cycle phases. The SCCS supports transparent, consistent cost classification, enabling improved cost estimation, benchmarking, monitoring, and reporting for both legacy and renewable energy projects.

Key Topics

• Comprehensive Cost Classification: SCCS offers a systematic way to categorize capital expenditure (CAPEX), operating expenditure (OPEX), work hours, and resource quantities for projects in traditional oil and gas as well as lower carbon energy domains.
• Faceted Coding Structures:
  • Physical Breakdown Structure (PBS): Hierarchical codes for physical/functional asset components, such as offshore installations, onshore facilities, and infrastructure for wind farms.
  • Standard Activity Breakdown (SAB): Structured coding for types of project activities, from management and engineering to construction and operation, with optional prefixes to specify life cycle phases (e.g., Explore, Execute, Operate, Abandon).
  • Code of Resource (COR): Hierarchical system to classify resources-materials, labor, equipment, overheads-involved in asset development and operation.
• Data Exchange and Integration: The standard enables efficient, reliable data exchange among stakeholders (operators, contractors, vendors, regulatory bodies) and seamless implementation in cost management systems.
• Adaptability and Extension: Organizations may extend the coding structures for additional detail or to address unique requirements, provided modifications are documented and clearly distinguished.

Applications

The SCCS as defined by ISO 19008:2026 delivers clear practical benefits for various stages and stakeholders within the oil, gas, and lower carbon energy sectors:

• Cost Estimation: Uniform codes help project teams estimate costs more accurately across all project phases-from concept selection and engineering to decommissioning.
• Benchmarking: Consistent data collection enables robust comparisons across projects, facilities, and organizations, supporting performance improvement and risk management.
• Cost Monitoring and Reporting: Enables detailed or high-level cost breakdowns to be tailored to organizational or contractual reporting needs, supporting accountability and transparency throughout the supply chain.
• Contract and Regulatory Compliance: The SCCS framework supports compliance with internal cost accounting, national and government reporting rules, tax requirements, and billing procedures.
• Life Cycle Management: Facilitates complete project life cycle costing, supporting strategic investment decisions, reliability management, and sustainability initiatives, including lower carbon solutions and climate change considerations.

Related Standards

For comprehensive asset and cost management in the energy sector, the following standards are closely related:

• ISO 15663:2021 - Life cycle costing for the petroleum, petrochemical, and natural gas industries.
• ISO 14224:2016 - Guidelines for the collection and exchange of reliability and maintenance data for equipment.
• ISO 20815:2018 - Production assurance and reliability management in petroleum and natural gas industries.
• ISO Guide 84:2020 - Guidelines for addressing climate change in standards.

Implementing SIST EN ISO 19008:2026 helps organizations in the oil, gas, and lower carbon energy sectors achieve greater efficiency, comparability, and compliance in project and asset cost management. By applying internationally recognized cost coding systems, companies enhance their ability to benchmark, control, and optimize expenditures, supporting the industry’s transition to sustainable and responsible energy solutions.

ISO 19008:2026(en)
Introduction
The oil and gas industries including petrochemical and lower carbon energy activities involve large capital
expenditure (CAPEX) as well as operating expenditure (OPEX).
The purpose of the standard cost coding system (SCCS) is to enable collecting, organizing and reporting
the costs of project development and operations, allowing for the analysis and comparison across projects
and assets. The SCCS can also be utilized to capture additional data such as physical quantities, contextual
information and cost classification information. This facilitates the development and benchmarking of unit
costs and cost metrics.
The SCCS is composed of three complementary and disjoint sub-classifications, known as facets:
a) physical assets, coded by the physical breakdown structure (PBS);
b) activities, coded by the standard activity breakdown structure (SAB);
c) resources, coded by the code of resource structure (COR).
This document contains the principles and usage of the SCCS. It also includes implementation requirements
for the expansion of the coding system by individual organizations.
The annexes include:
— Annexes A, B and C specify the SCCS codes, their names and descriptions;
— Annex D specifies typical relationships between the SCCS facets;
— Annex E provides examples of use of the codes.
Application of this document can also be useful when performing production assurance, reliability
management, and life cycle costing; see ISO 20815, ISO 14224 and ISO 15663.
