ISO 10426-4:2004(E)
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 10426-4 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 3, Drilling and completion fluids,
and well cements.
ISO 10426 consists of the following parts, under the general title Petroleum and natural gas industries —
Cements and materials for well cementing:
 Part 1: Specification
 Part 2: Testing of well cements
 Part 3: Testing of deepwater well cement formulations
 Part 4: Preparation and testing of foamed cement slurries at atmospheric pressure
 Part 5: Determination of shrinkage and expansion of well cement formulations at atmospheric pressure

ISO 10426-4:2004(E)
Introduction
Users of this part of ISO 10426 should be aware that further or differing requirements may be needed for
individual applications. This part of ISO 10426 is not intended to inhibit a vendor from offering, or the
purchaser from accepting, alternative equipment or engineering solutions for the individual application. This
may be particularly applicable where there is innovative or developing technology. Where an alternative is
offered, the vendor should identify any variations from this International Standard and provide details.
Cements or cement blends used for foamed cement slurry preparation at atmospheric pressure should be fit
for purpose. Such cements could include well cements of ISO Classes, high alumina cement, or other
speciality cements. The cements and blending materials should conform to appropriate standards. Where
International Standards do not exist, conformance with other appropriate standards should be made.
In this part of ISO 10426, where practical, U.S. Customary units are included in brackets for information.
INTERNATIONAL STANDARD ISO 10426-4:2004(E)

Petroleum and natural gas industries — Cements and materials
for well cementing —
Part 4:
Preparation and testing of foamed cement slurries at
atmospheric pressure
1 Scope
This part of ISO 10426 defines the methods for the generation and testing of foamed cement slurries and their
corresponding unfoamed base cement slurries at atmospheric pressure.
2 Normative references
The following normative document is indispensable for the application 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.
ISO 10426-2:2003, Petroleum and natural gas industries — Cements and materials for well cementing —
Part 2: Testing of well cements
3 Sampling
3.1 General
Samples of the cement material or cement blend, solid and liquid additives, and water used for mixing are
required to test a foamed cement slurry in accordance with this part of ISO 10426. Accordingly, the best
available sampling technology should be employed to ensure the test materials match as closely as possible
those found at the well site.
3.2 Method
Applicable sampling techniques for the fluids and materials used in foamed cementing operations can be
found in ISO 10426-2:2003, Clause 4. If required, the temperatures of the mix water, cement or cement
blends, and liquid additives may be measured with a thermocouple or thermometer capable of measuring
temperature with an accuracy of ± 2 °C (± 3,5 °F). These temperatures should be recorded. Temperature-
measuring devices shall be calibrated (in the case of a thermocouple) or checked for accuracy (in the case of
a thermometer) annually.
4 Slurry calculations
4.1 Calculation of base cement slurry composition with and without surfactant(s)
The final base cement slurry for preparing a foamed cement slurry contains surfactant(s), which cannot be
added to the base cement slurry for initial mixing. This requires calculation of the relative mass percentage
(mass fraction) of the surfactant(s) in the foamed cement slurry. This is done by taking the total mass of the
ISO 10426-4:2004(E)
surfactant(s) and dividing by the total mass of th
