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 15136-1 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.
This second edition cancels and replaces the first edition (ISO 15136-1:2001), which has been technically
revised.
ISO 15136 consists of the following parts, under the general title Petroleum and natural gas industries —
Progressing cavity pump systems for artificial lift:
⎯ Part 1: Pumps
⎯ Part 2: Surface-drive systems

ISO 15136-1:2009(E)
Introduction
This part of ISO 15136 has been developed by users/purchasers and suppliers/manufacturers of progressing
cavity pumps and is intended for use in the petroleum and natural gas industry worldwide. This part of
ISO 15136 provides requirements and information to both parties in the selection, manufacturing, testing, and
using progressing cavity pumps as defined in the scope. Further, this part of ISO 15136 addresses supplier
requirements, which set the minimum parameters with which it is necessary that suppliers comply to claim
conformity with this part of ISO 15136.
This part of ISO 15136 provides grades of requirements for design validation, quality control and functional
evaluations allowing the user/purchaser to select each for a specific application. There are three grades of
design validation and quality control, and two grades of functional testing. Design validation grade V3 is
restricted to legacy products, the basic grade is V2 and the highest grade is V1. Quality control grade 3 is the
standard grade and grades 2 and 1 provide additional requirements. Functional evaluation grade F1 requires
a hydraulic test of the PCP and grade F2 does not. The user/purchaser has the option of specifying
requirements supplemental to these grades.
It is necessary that the users of this part of ISO 15136 be aware that requirements above those outlined in this
part of ISO 15136 can be needed for individual applications. This part of ISO 15136 is not intended to inhibit a
supplier/manufacturer from offering, or the user/purchaser from accepting, alternative equipment or
engineering solutions. This can be particularly applicable where there is innovative or developing technology.
Where an alternative is offered, it is the responsibility of the supplier/manufacturer to clearly and completely
identify any variations from the requirements of this part of ISO 15136.

5 Functional specification
5.1 General
The user/purchaser shall prepare a functional specification to order products that conform to this part of
ISO 15136 and specify the following requirements and operating conditions as appropriate and/or identify the
supplier/manufacturer's specific product. This information is used by the supplier/manufacturer to recommend
the PCP and/or components for the application. These requirements and operating conditions may be
conveyed by means of a user/purchaser functional-specification form (Annex H) and operational guidelines
(Annex F). The user/purchaser shall specify the units of measurement for the data provided.
PCPs are designed for specific applications; their use in new/different applications requires a detailed
evaluation by the user/purchaser to ensure that the system can operate properly in all aspects in that new
application. Annexes E and F contain installation and operational guidelines that can be relevant in this
consideration. The process used to evaluate the new application shall be no less stringent than that required
for the initial application.
5.2 PCP type description
The user/purchaser shall select a PCP on the basis of the following conditions:
a) production requirements;
b) fluid characteristics;
c) surface equipment configuration;
d) stator conveyance method, such as drive string, tubing, wireline, coiled tubing.
5.3 Functional requirements
5.3.1 Application parameters
5.3.1.1 General
While installed, the PCP shall perform in accordance with its functional requirements, which are typically
determined based on application parameters. These parameters include, but are not limited to, those listed in
5.3.1.2 to 5.3.3.4, as applicable.
