Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
Cost management within the petroleum, petrochemical and natural gas industries is important and
will benefit from the adoption of a common and consistent approach to life cycle costing.
Life cycle costing is the systematic consideration of costs and revenues associated with alternative
options required to fulfil the objectives of the business. It is an iterative process of planning, estimating
and monitoring costs and revenue differences throughout an asset's life. It is used to support the
decision-making process by evaluating alternative options and performing trade-off studies. While the
largest benefits are typically achieved in the early life cycle phases, it is equally applicable to all life
cycle phases and at many levels of detail.
The petroleum, petrochemical and natural gas industries have historically assessed the financial
viability of project options based on minimum capital expenditure and achieving project schedule,
whilst operating expenditures and lost revenue have received less focus in the decision-making process.
This has ignored potentially large cost factors and has in some cases resulted in selecting non-optimal
solutions.
Recognizing this situation, life cycle costing is increasingly being applied by a variety of organizations
within the industry. All participants in the process — operators, contractors and vendors — can have a
substantial impact on the life cycle cost, and it is not until all are involved that the benefits sought from
the use of life cycle costing will be realized.

Petroleum, petrochemical and natural gas industries —
Life cycle costing
1 Scope
This document specifies requirements for and gives guidance on the application of life cycle costing
to create value for the development activities and operations associated with drilling, exploitation,
processing and transport of petroleum, petrochemical and natural gas resources. This document
covers facilities and associated activities within different business categories (upstream, midstream,
downstream and petrochemical).
The life cycle costing process as described in this document is applicable when making decisions
between competing options that are differentiated by cost and/or economic value. This document is not
concerned with decision-making related to the economic performance of individual options or options
differentiated by factors other than cost or economic value.
Guidance is provided on the management methodology and application of life cycle costing in support
of decision-making across life cycle phases. The extent of planning and management depends on the
magnitude of the costs involved, the potential value that can be created and the life cycle phase. It also
provides the means of identifying cost drivers and provides a cost-control framework for these cost
drivers, allowing effective cost control and optimization over the entire life of an asset.
