Design Integrity

The Well Design must:

  • Incorporate all safety considerations required throughout the campaign.
  • Comply with Local Government Regulations, Safety and Well Integrity Policies.
  • Satisfy all Operating Requirements for the well.
  • Specify necessary equipment, devices and / or services with their sizes, specifications, models, manufacturers, operating conditions, limitations, etc for all planned well operations.
  • Include a Well Barrier Management System for the Sequence of Planned Well Operations.

Technical Integrity

  • The Well Plan must contain appropriate Operating Procedures for All Planned Well Operations.
  • An Effective Well Operations Management System must be established in the Design and Preparation Stage.
  • The Well Plan must adhere to International / Internal / Regional Policies for Safe Well Construction:
    1. a) Well Control Policy.
    2. b) Well Integrity Policy.
    3. c) Well Engineering Policy.
    4. d) QHSE Policy.
  • Include a Well Barrier Surveillance Plan for the Sequence of Planned Well Operations.

Operational Integrity

  • Real-time Well Monitoring.
  • QAQC of Field Data.
  • Effective Logistics Management during Operations.
  • Periodic Well Barrier Surveillance.
  • Compliance to Rig Site Safety Requirements (PTW, Stop Cards, PPE, Hot Works, etc).
    1. a) Daily Reports (DDRs, DMRs, DGRs, etc).
    2. b) End of Well Report,
    3. c) HSE Reports,
    4. d) Incident Report,
    5. e) Near-Miss Reports.

Structural Integrity

  • Adequate Soil Testing at Offshore Jack Up Locations to be performed Ensure Rig Stability during Operations.
  • Testing and Verification of DP Systems in Floaters.Although not a ‘Barrier’, DP failure may lead to loss of Well Integrity (Riser Damage, Drill Pipe Bucking, etc).
  • Selection of Optimum Casing Weight, Grade and Connections for all sections of the well.
  • Practical Cementing Design and Installation with appropriate additives for each section.
  • Pile Driving / Jetting the Conductor to a verified point to refusal to avoid punch-through.

Organizational Integrity

  • Competency Training to Spread Awareness on Well Integrity and Well Barrier Management beyond Well Control.
  • Training on International / Regional Well Integrity Standards.
  • Competency Development through Simulations and On-Site Training.
  • A well-defined Management of Change (MoC) process to document and manage changes to a program.
  • Rig Site Well Integrity Training:
    1. Identifying Primary and Secondary Well Barriers.
    2. Monitoring / Judging Well Barrier Conditions.
    3. Well Barrier Re-Establishment.
    4. Safety Drills.
