Industry Recommended Practices (IRPs)

The Drilling and Completions Committee (DACC) is responsible for the development of recommended technical operating practices for the upstream oil and gas industry in the areas of drilling, completions and servicing of wells. The primary focus of DACC is to develop technical industry recommended practices (IRPs), where the objectives include cost efficiencies, technical optimization, productivity, safety and environmental performance.

PSAC is a strong supporter of the IRP process, and our members participate in their development.

IRPs provide guidance or best practices to conduct operations in a safe and technically acceptable manner. They are developed to meet, or exceed, the minimum intent of the applicable legislation in the on-shore jurisdictions in which the industry operates.

IRP Volume #1 – Critical Sour Drilling
Set of best practices and guidelines, designed to provide advice regarding Drilling Critical Sour Wells.

IRP Volume #2 Completing and Servicing Critical Sour Wells
Addresses the installation, operation and maintenance of wellheads and wellhead related equipment during initial completions, re-completions, or subsequent production operations of critical sour gas or oil wells.

IRP Volume #3 – In Situ Heavy Oil Operations
Identifies recommended practices relevant to in situ heavy oil operations regarding worker safety, public safety, and environmental protection across the life cycle of an in situ heavy oil project.

IRP Volume #4 – Well Testing and Fluid Handling
The purpose of this IRP is to ensure that guidelines for well testing and fluid handling operations are in place and readily available for all personnel.

IRP Volume #5 – Minimum Wellhead Requirements
This IRP provides an introduction to wellhead components and major variations in wellhead design that are driven by reservoir and well operating considerations and conditions.

IRP Volume #6 – Critical Sour Underbalanced Drilling
This IRP applies to the underbalanced drilling of critical sour wells.

IRP Volume #7 – Standards for Wellsite Supervision of Drilling, Completion and Workovers
This IRP deals with well operations that are generally known in the industry as drilling, completions and workovers.

IRP Volume #8 – Pumping of Flammable Fluids
IRP 8 addresses the issue of safe handling and pumping of flammable fluids during well servicing operations.

IRP Volume #13 – Slickline Operations
IRP 13 is a guideline intended for slickline service companies to develop an appropriate slickline service program that promotes slickline worker safety on the job.

IRP Volume #14 – Non-Water Based Drilling Fluids
IRP 14 provides introductory information on the makeup and use of non-water based drilling fluid.

IRP Volume #15 – Snubbing Operations
The purpose of this document is to provide easily accessible snubbing operation guidelines for all personnel involved in the development, planning and execution of the snubbing program.

IRP Volume #20 – Wellsite Design Spacing Recommendations
IRP 20 (2015) is designed to clarify the criteria that should influence size design. This IRP promotes robust and integrated up-front planning to ensure a successful application that provides for the entire lifecycle of the well, from initial construction and drilling, through completions and production.

IRP Volume #21 – Coiled Tubing Operations – DRAFT
DRAFT IRP 21 (2016) represents a revised version of the sanctioned IRP 21 (2010), following a limited scope review. The key revisions include reformatting to match the current style guide, updated references, and most importantly, a revision of the Well Servicing Pressure Categories.

IRP Volume #22 – Underbalanced and Managed Pressure Drilling Operations Using Jointed Pipe
This IRP is a two part document consisting of:

Interim IRP Volume #24 – Fracture Stimulation
This IRP adopts a risk-based approach to develop a process for reviewing, assessing, and developing controls to minimize risk during fracture stimulation operations. The recommendations in this IRP allow for mindful planning and carefully designed control measures that reduce risk to an acceptable level.

IRP Volume #25 – Primary Cementing – DRAFT
Draft IRP 25 (2016) focuses on the cementing practices and factors that can impact the success of a primary cement job.
