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.
To access the IRPs, click on the appropriate link:
IRP Volume #1 – Critical Sour Drilling
This IRP provides the operator with advice, best practices and guidelines regarding drilling critical sour wells.
IRP Volume #2 – Completing and Servicing Critical Sour Wells
This IRP enhances safe operations by providing information and recommendations for the completing and servicing of critical sour wells.
IRP Volume #3 – In Situ Heavy Oil Operations
This IRP identifies recommended practices regarding worker safety, public safety, and environmental protection across the life cycle of an in situ heavy oil project. It may act as a guideline for Operators and Service Companies during employee training, or may be accessed as a guide to support the development of internal procedures for safe in situ heavy oil operations practices.
IRP Volume #4 – Well Testing and Fluid Handling
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 driven by reservoir and well operating considerations and conditions.
IRP Volume #6 – Critical Sour Underbalanced Drilling Industry
This IRP applies to the underbalanced drilling of critical sour wells.
IRP Volume #7 – Competencies For Critical Roles in Drilling and Completions
This IRP focuses on safety through training, certification and competency requirements of the wellsite supervisor.
IRP Volume #8 – Pumping of Flammable Fluids
This IRP addresses the issue of safe handling and pumping of flammable fluids during well servicing operations. It includes recommended practices for a well servicing operation with flammable fluid storage tanks, multiple personnel and equipment.
IRP Volume #13 – Wireline Operations
This IRP (formerly Slickline Operations) focuses on equipment, practices and maintenance to ensure safe operation of wireline related equipment.
IRP Volume #14: Non-Water Based Drilling Fluids
This IRP provides an introduction to the makeup and use of non-water based drilling fluid. This resource offers both general and specific recommendations to minimize the hazards and control risks.
IRP Volume #15 – Snubbing Operations
This IRP 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
This IRP is designed to clarify criteria that should influence size design. It promotes robust and integrated upfront planning to ensure a successful application that provides for the entire life cycle of the well.
IRP Volume #21 – Coiled Tubing Operations
This IRP ensures that guidelines for coiled tubing (CT) operations are in place and readily available for all personnel involved in the development, planning, and completion of CT operations.
IRP Volume #22 – Underbalanced Drilling and Managed Pressure Drilling Operations using Jointed Pipe
This IRP provides an overview of underbalanced and managed pressure drilling operations, a RMD checklist and a hazard and risk assessment register. This IRP has four parts: Underbalanced and Managed Pressure Drilling Operations; RMD Checklist; MPD Checklist; and Hazard and Risk Assessment Register – Risk Register.
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.
IRP Volume #25 – Primary Cementing
This IRP focuses on the cementing practices and factors that impact the success of a primary cement job, considering all phases of the job from job design through execution and post-job evaluation.
IRP Volume #26 – Wellbore Remediation
This IRP provides best practices for performing efficient, long-lasting wellbore remediation while mitigating impacts to the environment and protecting groundwater.
