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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

Introduction

The petroleum, petrochemical and natural gas industries involve large capital expenditure as well

as operating expenditure. Revenue loss caused by production loss will affect the profitability of such

industry and for a specific plant operatorship.

Production efficiency (PE) is a term often used by operators for historic production availability in the

operating phase. PE is a reported measure, and it can be compared with the predicted (or targeted)

production availability made during a project development stage. Furthermore, PE is forecasted and

tracked during the operating phase to allow tracking of performance. ISO 20815:2018 addresses

production assurance activities including analytical methods for predicting production availability,

and also includes a production loss categorization.

This document supports this production loss categorization with a harmonized approach for calculating

and reporting production loss and production efficiency in the operating phase, including forecasting

during this life cycle phase. This will enable precise and consistent feedback of production performance

for use in production and operational planning to achieve optimal PE for the operators and associated

industry stakeholders. Focus is given to actual produced volume and reference production volume, e.g.

production potential that will depend on reservoir and well constraints, plant/process constraints,

export/transportation constraints and market constraints. Standardization of PE reporting across

the industry will drive consistency and provide better quality PE information and communication for

operators and partners.

Petroleum, petrochemical and natural gas industries —
Calculation and reporting production efficiency in the
operating phase
1 Scope

This document provides requirements and guidance for reporting of production performance data and

production loss data in the operating phase by use of production loss categorization. It supplements the

principles of ISO 20815:2018, Clause E.3 and Annex G by providing additional details.

This document focusses on installations and asset elements within the upstream business category.

Business categories and associated installations and plants/units, systems and equipment classes are

used in line with ISO 14224:2016, Annex A.

The production loss categories given in Annex A are given at a high taxonomic level and supplements

the reporting of failure and maintenance parameters as defined in ISO 14224:2016, Annex B.

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

For the purposes of this document, the following terms and definitions apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— IEC Electropedia: available at http:// www .electropedia .org/
3.1 Terms and definitions
3.1.1
achieved production potential

production potential (3.1.43) that in retrospect can be verified as the maximum achievable production

in a given time period

Note 1 to entry: Achieved production potential is the sum of the achieved production and the estimated

production loss (3.1.40) occurring in the four production potential elements: well production potential (3.1.58),

plant production capacity (3.1.34), export capacity (3.1.12) and market potential (3.1.26).

Note 2 to entry: Achieved production potential can vary over time.

ISO/TS 3250:2021(E)
3.1.2
asset

item (3.1.21), thing or entity that has potential or actual value to an organization

Note 1 to entry: Physical assets usually refer to equipment, inventory and properties owned by the organization.

Physical assets are the opposite of intangible assets, which are non-physical assets such as leases, brands, digital

assets, licenses, intellectual property rights, reputation or agreements.

Note 2 to entry: A grouping of assets referred to as an asset system (see ISO 55000:2014, 3.2.5) could also be

considered as an asset.

Note 3 to entry: In this document, 'asset' only refers to the physical assets, which are tangible assets. An

organization can also operate assets that are wholly owned or partly owned through joint ventures or other

arrangements. Typically, an asset is a facility or an installation, or a group of facilities. The facility corresponds

to an installation category in ISO 14224:2016, Table A.1. These installations can be subdivided into plant/units,

systems (3.1.50), equipment classes (3.1.11), subunits, components, etc. as described in ISO 14224:2016, Table 2. In

this document, asset element (3.1.3) is used to group these as shown in Table A.2.

[SOURCE: ISO 55000:2014, 3.2.1, modified — Notes 2 and 3 to entry have become Notes 1 and 2 to entry,

respectively, new Note 3 to entry has been added.]
3.1.3
asset element

underlying item (3.1.21) for the asset (3.1.2) that is needed for the asset to deliver its product

Note 1 to entry: In this document, which is applicable for upstream business category, the asset elements are

wells (including reservoir), subsea installations, production facilities (including process and utilities), and export

and import facilities as shown in Table A.2. For other business categories, the asset elements will be different.

Note 2 to entry: The underlying items of the individual asset element will be systems (3.1.50) and relevant

equipment classes (3.1.11) as defined in ISO 14224:2016, and as shown in Table D.1.

3.1.4
availability
ability to be in a state to perform as required

Note 1 to entry: Various availability terms are defined in ISO 14224:2016, ISO 20815:2018 and ISO/TR 12489:2013.

[SOURCE: IEC 60050-192:2015, 192-01-23, modified — Note 1 to entry has been modified, Note 2 to

entry has been deleted.]
3.1.5
conventional resources

oil and gas resources where the reservoir rock characteristics and fluid trapping mechanisms permit

reservoir fluids to readily flow into the wellbore

Note 1 to entry: This usually includes conventional, reasonably permeable and connected, sandstone and

carbonate reservoirs.
3.1.6
corrective maintenance
maintenance (3.1.24) carried out after fault detection to effect restoration

[SOURCE: IEC 60050-192:2015, 192-06-06, modified — Note 1 to entry has been deleted.]

3.1.7
deliverability

ratio of deliveries to planned deliveries over a specified period of time, when the effect of compensating

elements, such as substitution from other producers and downstream buffer storage, is included

Note 1 to entry: See Figure B.1 for further information.
