Overview
ISO 15136-2:2006 specifies requirements for progressing cavity pump (PCP) surface‑drive systems used for artificial lift in the petroleum and natural gas industries. The standard covers design, design verification and validation, manufacturing and data control, performance ratings, testing and repair for products that meet the definition of a surface‑drive system. Informative annexes offer guidance on brake system selection/installation/operation and on the selection and use of sucker rods in PCP rotary pumping applications. Items not covered (unless integral) include bottom drives, polished rod clamps, stuffing boxes, electrical controls and common auxiliary equipment.
Key topics and technical requirements
- Functional specification: System type selection, functional characteristics, environmental and equipment compatibility, and validation planning.
- Technical specification and design: General technical characteristics, design criteria, allowable design changes, design scaling and heat/torque considerations.
- Design verification & validation: Requirements for engineering verification, product functional testing and additional testing to demonstrate conformity.
- Supplier requirements & documentation: Manufacturing data control, product identification, job‑lot traceability and quality control documentation (two grades: Q2 standard and Q1 for additional documentation).
- Performance ratings and limits: Input power, maximum operating torque, operating speed/temperature ranges, axial‑load and backspin limits.
- Repair and shipment: Minimum requirements for repair practices and preparation for transportation.
- Informative annexes: Elastomer/non‑metallic material requirements; brake system evaluation and test methods; installation and operation guidelines; equipment selection; and a purchaser functional specification form.
Practical applications - who uses ISO 15136-2
- Manufacturers/suppliers of PCP surface‑drive systems to define design, testing and quality control programs.
- Operators and purchasers specifying procurement requirements and evaluating vendor conformity.
- Design and field engineers responsible for system selection, installation, commissioning and troubleshooting of artificial lift equipment.
- Inspection, maintenance and repair teams aligning repairs and shop testing with standard requirements.
- Regulatory bodies and auditors assessing compliance with industry best practice.
