Petroleum and natural gas industries - Cements and materials for well cementing - Part 5: Determination of shrinkage and expansion of well cement formulations at atmospheric pressure (ISO 10426-5:2004)

ISO 10426-5:2004 provides the methods for the testing of well cement formulations to determine the dimension changes during the curing process (cement hydration) at atmospheric pressure only. This is a base document, because under real well cementing conditions shrinkage and expansion take place under pressure and different boundary conditions.

Industries du pétrole et du gaz naturel - Ciments et matériaux pour la cimentation des puits - Partie 5: Détermination du retrait et de l'expansion a la pression atmosphérique des formulations de ciments pour puits (ISO 10426-5:2004)

L'ISO 10426-5:2004 fournit les méthodes d'essai des formulations de ciments pour puits afin de déterminer les variations de dimensions au cours du processus de vieillissement (hydratation du ciment), à la pression atmosphérique uniquement. Il s'agit d'un document de base, car, dans les conditions réelles de cimentation des puits, le retrait et l'expansion se produisent sous pression et dans des conditions d'environnement différentes.

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 10426-5 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

ISO 10426-5:2004(E)
Introduction
Dimensional changes in oil- and gas-well cements after placement, phenomena often referred to as shrinkage,
(when the dimensional change corresponds to a decrease in cement volume) have often been used to explain
various wellbore phenomena including
 a microannulus, leading to a bad bond as demonstrated by the bond log;
 interzonal communication, resulting in costly remedial operations;
 lack of a hydraulic seal when utilizing cement inflatable packers.
Attempts have been made to find additives that decrease cement shrinkage (shrinkage being a fundamental
characteristic of Portland cement) The best solution for shrinkage thus far has been the identification of
additives that favour the expansion of the cement. However, even if cement expands dimensionally, it will still
shrink internally. In this case, the bulk expansion of the cement sample is simply superimposed on an inner
shrinkage that will affect the porosity of the sample.
Shrinkage and expansion in cement result from the formation of hydration products having a density different
from the compounded density of the reaction components. This can result in the following:
 change in pore volume;
 change in pore pressure;
 change in sample dimensions;
 change in internal stress.
In a closed cell with a non-deformable boundary, the volume of hydrates produced during the chemical
reaction is less than the volume of dry compounds plus water. The change in volume of hydrates will be
referred to as inner hydration shrinkage. The change in the sample dimensions will be referred to as bulk
shrinkage or expansion. Bulk shrinkage and expansion of cement refer to the result of the measurement of
linear dimensional change or volume change. The volume to which all volume changes are related is the
volume of the slurry immediately after mixing and emplacement in the experimental equipment.
In this part of ISO 10426, units are given as SI, and where practical, U.S. Customary units are included in
brackets for information.
Users of this part of ISO 10426 should be aware that further or differing requirements might 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
can 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.

Determination of shrinkage and expansion of well cement
formulations at atmospheric pressure
1 Scope
This part of ISO 10426 provides the methods for the testing of well cement formulations to determine the
dimension changes during the curing process (cement hydration) at atmospheric pressure only. This is a base
document, because under real well cementing conditions shrinkage and expansion take place under pressure
and different boundary conditions.

references, only the edition cited applies. For undated references, the latest edition of the referenced

4 Sampling
4.1 General
Samples of the neat cement or cement blend, solid and liquid additives, and mixing water are required to test
a slurry according to this part of ISO 10426. Accordingly, the best available sampling technology should be
employed to ensure the laboratory test conditions and materials match as closely as possible those found at
the wellsite. Some commonly used sampling devices are shown in ISO 10426-2:2003, Figure 1.
4.2 Method
Applicable sampling techniques for the fluids and materials used are specified in ISO 10426-2:2003, Clause 4.
5 Determination of shrinkage or expansion under conditions of free access of water
at atmospheric pressure — Annular ring test
5.1 General information
The annular expansion mould is a device suitable for measuring only the linear bulk shrinkage or expansion
properties of a cement formulation. The magnitude of expansion depends on the amount of expanding agent,
cement powder, slurry design and curing condition (pressure, temperature, time, fluid access). It should be
noted that expansion is strongly affected by boundary conditions. The chemical process of mineral growth is
strongly controlled by the state of stress and mineral growth will tend to occur where the stress value is the
lowest, i.e. in pore space or empty spaces. Therefore, the degree of cement shrinkage and expansion is
dependent on a number of conditions, not all of which can be uniquely defined. The test does not represent
fully the annulus of a well.

5.2.1.2 Mould calibration
The resilience of the ring of the mould shall be calibrated annually. The resilience shall be such that the mass
of 1 000 g ± 1 g (2,204 6 lb ± 0,002 lb) applied as shown in Figure 4 shall increase the distance between the
two steel measurement balls (see Figure 9) by 2 mm ± 0,3 mm (0,078 7 in ± 0,011 8 in) without permanent
deformation.
Attention must be paid to ensure that the load is applied perpendicular to the gap (90°) in order to avoid errors,
which might be easily made. The readings shall be repeated at least three times to obtain an average value
with a standard deviation of 0,05 mm (0,002 in).
