Well Testing and Fluid Handling Industry Recommended Practice (IRP) provides guidelines for well testing and fluid handling operations for all personnel.
August 18, 2021

The environmental, safety and health risks associated with well testing and fluid handling can be minimized by ensuring workers are properly trained, implementing prudent procedures and using properly designed equipment.

The purpose of this document is to ensure that guidelines for well testing and fluid handling operations are in place and readily available for all personnel.

The intended audience of this document includes oil and gas company engineers, field consultants, well testing and fluid hauling personnel, other specialized well services personnel and regulatory bodies. IRP 4 (2015) is divided into five sections that cover the following topics:

  • Roles and responsibilities for owners, contractors, and other subcategories of companies involved in well testing and fluid handling.
  • Worker safety that outlines requirements for on-site workers and environmental protection
  • West testing that provides recommendations for equipment design and operation, purging, and pressure testing.
  • Specific flowback related recommendations to cover off a variety of operations including flowing, pumping, or circulating to an open tank system, swabbing, snubbing, and recovery and handling of liquid petroleum gases.
  • Loading, unloading and transportation of fluids.
