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 10427-3 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.
This first edition cancels and replaces the first edition of ISO 18165, which has undergone an ISO number
change and a minor revision.

Petroleum and natural gas industries — Equipment for well
cementing —
Part 3:
Performance testing of cementing float equipment
1 Scope
This part of ISO 10427 describes testing practices to evaluate the performance of cementing float equipment
for the petroleum and natural gas industries.
This part of ISO 10427 is applicable to float equipment that will be in contact with water-based fluids used for
drilling and cementing wells. It is not applicable to float equipment performance in non-water-based fluids.
2 Functions of cementing float equipment
The term “cementing float equipment” refers to one or more check valves incorporated into a well casing string
that prevent fluid flow up the casing while allowing fluid flow down the casing. The primary purpose of
cementing float equipment is to prevent cement that has been placed in the casing/wellbore annulus from
flowing up the casing (U-tubing). In some cases, such as liner cementing, float equipment may be the only
practical means of preventing U-tubing. In other cases, the float equipment serves to allow the cement to set
in the annulus without having to increase the pressure inside the casing to prevent U-tubing. Increased
pressure in the casing while cement sets is generally undesirable because it can result in gaps (micro-annuli)
in the cemented annulus.
Float equipment is also sometimes used for the purpose of lessening the load on the drilling rig. Since float
equipment blocks fluid flow up the casing, the buoyant force acting on casing run with float equipment is
greater than the buoyant force acting on casing run without float equipment. If either the height or the density
of the fluid placed inside casing equipped with float equipment while the casing is being run is less than that of
the fluid outside the casing, the suspended weight of the casing is reduced compared with what it would be
without the float equipment.
The ability of float equipment to prevent fluid flow up the casing is also important in certain well control
situations. If the hydrostatic pressure of the fluid inside the casing becomes less than the pressure of
formation fluids in formations near the bottom of the casing, fluids from the well may try to flow up the casing.
In such a situation, the float equipment becomes a primary well control device.
Float equipment is also sometimes used as a device to assist in pressure testing of casing. This is normally
done by landing one or more cementing plugs on top of the float equipment assembly. The plugs seal the
casing so that the pressure integrity of the casing may be tested.
Float equipment is also used by some operators as a device to lessen the free fall of cement inside the casing.
The free fall of cement is the tendency of cement to initially fall due to the density differences between the
cement and the fluid in the well. The float equipment lessens the free fall, to some extent, by providing a
constriction in the flow path.
Casing fill-up float equipment is a special type of float equipment that allows the casing to fill from the bottom
as the casing is run. This is desirable, in some cases, to help reduce pressure surges as the casing is lowered.
Fill-up type float equipment also helps ensure that the collapse pressure of the casing is not exceeded. Once
the casing is run, the check valve mechanism of fill-up type float equipment is activated. This is normally done
by either pumping a surface-released ball through the equipment or by circulating above a certain rate.

3 Float equipment performance criteria
3.1 General
There are a number of performance criteria, listed below, that may be used to evaluate the suitability of a
particular piece of float equipment for a given well.
3.2 Durability under downhole conditions
Float equipment should still function after a fluid containing abrasive solids has been circulated through the
equipment for a period of time. The equipment should function in various orientations and while exposed to
elevated temperatures and pressures.
3.3 Differential pressure capability from below
Float equipment should be capable of withstanding a differential pressure with the higher pressure being
exerted from below the check valve, because the hydrostatic pressure of the fluid occupying the annulus
immediately after the cement has been placed is usually greater than the hydrostatic pressure of the
corresponding column of fluid inside the casing, or while the casing is being run.
3.4 Ability to withstand force exerted through cementing plugs from above
Float equipment should be able to withstand a force exerted through cementing plugs from above. Some
operators occasionally pressure-test the casing by increasing the pressure shortly after a cementing plug (top
plug) used to separate the cement from the displacement fluid has landed downhole. This can cause a force
to be applied to the float equipment that could cause the equipment to fail.
3.5 Drillability of the equipment
Float equipment should be easy to drill through, since in many cases, float equipment must be drilled out after
cementing.
3.6 Ability to pass lost circulation materials
Float equipment may be required to allow easy passage of lost circulation material (LCM). On occasion, the
fluid that is circulated through cementing float equipment contains LCM designed to bridge on highly
permeable, vugular or fractured formations to lessen the amount of fluid that is lost to the formations. Since
float equipment generally provides a constricted flow area for fluid passage, there can be a tendency for the
LCM to bridge on the float equipment valve and partially or totally block fluid circulation. Therefore, the ease
with which the LCM can pass through the float equipment may be a performance criterion for some wells.
3.7 Flow coefficient of the valve
Since float equipment provides a constriction in the flow path, there will be a pressure loss associated with
circulating fluid through the float valve. If the pressure loss through the float equipment is too high, circulation
rates can be limited. In some cases, however, a large pressure loss is desirable to reduce free fall of the
cement. The flow coefficient of the valve provides a means of estimating the pressure loss for a given fluid
density and a given rate.
3.8 Reverse-flow resistance of casing fill-up valves
One of the functions of casing fill-up float equipment is to reduce pressure surges as the casing is run by
allowing flow into the casing from the bottom. Therefore, the resistance of the valve to reverse flow is
indicative of the relative performance of the valve in reducing surge pressure.
