ISO 15136-2:2006(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 15136-2 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 4, Drilling and production
equipment.
ISO 15136 consists of the following parts:
⎯ Downhole equipment for petroleum and natural gas industries — Progressing cavity pump systems for
artificial lift — Part 1: Pumps
⎯ Petroleum and natural gas industries — Progressing cavity pump systems for artificial lift — Part 2:

ISO 15136-2:2006(E)
Introduction
This part of ISO 15136 has been developed by users/purchasers and suppliers/manufacturers of progressing
cavity pump surface-drive systems and is intended for use in the petroleum and natural gas industry
worldwide. ISO 15136-2 provides requirements and information to both parties in the selection, manufacturing,
testing, and using progressing cavity pump surface-drive systems as defined in the scope. Further,
ISO 15136-2 addresses supplier requirements, which set the minimum parameters with which suppliers shall
comply to claim conformity with this International Standard.
ISO 15136-2 has been structured to allow for grades of increased requirements in quality control
documentation. These variations allow the user/purchaser to select the grade that is required for a specific
application.
There are two quality control documentation grades, which provide the user/purchaser the choice of
requirements to meet their preference or application. Quality control documentation grade Q2 is the standard
grade offered and quality control documentation grade Q1 provides additional documentation. Additional
requirements can be specified by the user/purchaser as supplemental requirements.
Users of this International Standard should be aware that requirements above those outlined in this
International Standard may be needed for individual applications. This International Standard is not intended
to inhibit a supplier/manufacturer from offering, or the user/purchaser from accepting, alternative equipment or
engineering solutions. 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 part of ISO 15136-2 and
provide details.

5 Functional specification
5.1 General
The user/purchaser shall prepare a functional specification to order products which conform to this part of
ISO 15136 and shall specify the following requirements and operating conditions as appropriate, and/or
identify the supplier’s/manufacturer’s specific product. This information is used by the supplier/manufacturer to
recommend the surface-drive systems and/or components for the application. These requirements and
operating conditions may be conveyed by means of a dimensional drawing, data sheet, or other suitable
communication in a format that conforms to this part of ISO 15136. An example of a functional specification
form for this information is provided as Annex F.
The user/purchaser shall ensure that the expected operating axial load, torque, speed, surface-drive system
temperature, power and braking requirements (where required) do not exceed the surface-drive system's
ratings. The maximum operating torque and the maximum dynamic fluid level are a function of the ability of
the surface-drive system to dissipate the energy stored in the production system after a shutdown, and may
be determined by using the data provided with the surface-drive technical specifications in an analytical
backspin model, such as the one described in Annex B.
5.2 Surface-drive system type selection
The user/purchaser shall select a drive system type (exclusive of prime mover type):
a) gear-reduction drive;
b) direct drive;
c) hydraulic drive.
5.3 Functional characteristics
5.3.1 General
The user/purchaser shall provide the operating speed and input power (torque), and axial load.
5.3.2 Application parameters
Functional characteristics are typically determined based on application parameters. These parameters may
include but are not limited to
a) anticipated flow rate, tubing head pressure at surface of produced fluid and pump intake pressure;
b) produced fluid composition (constituents, viscosity, specific gravity, temperature, et al.);
c) anticipated PCP model to be used;
d) PCP setting depth;
e) tubular sizes/weights/materials;
f) drive string diameter, type and material.
