As the number of ageing fields in Malaysia increases, the plugging and abandonment (P&A) of wells become a critical activity that carries major liability to operators and regulators. Experience in other parts of the world indicates that wells can make up over 50% of the overall field decommissioning costs. The need for competent technical staff trained in planning, managing and executing P&A has never been higher especially as well abandonment activities are at its early stage in Malaysia.

This in-depth training course will cover the complete topic of well decommissioning, including P&A methodologies, industry guidelines and regulations, and current best practices. Attendees will learn the basic principles of well P&A to effectively manage the risks and uncertainties associated with well decommissioning whilst also developing good planning practices and effective cost control.


By the end of the course, the delegate will be able to:

    • Become familiar with industry guidelines and the regulation of well decommissioning activities.
    • Develop a practical appreciation of P&A objectives, operational phases and well status classifications.
    • Consider a wide range of well structures (casing and completions) and the equipment required to access the well and execute P&A operations.
    • Solve common P&A challenges through an understanding of the P&A process for a range of well types.
    • Review P&A design and cost estimation processes including the identification, characterisation and management of risk.
    • Discuss project optimization and current trends in ‘best practice’ to improve the efficiency of P&A projects.

Key Benefits

    • Highly interactive learning approach
    • A clear understanding of the P&A issues and challenges
    • All delegates will receive comprehensive course documentation for use during and after the course
    • Hands-on case studies and insights from the trainer’s extensive experience
    • Open discussion to further engage and share best practices

About Expert Trainer

Our Expert Trainer is a UK based decommissioning advisor and training consultant with over 41 years of experience in Oil & Gas industry. 

His expertise is in all aspects of Well Construction (drilling, completions, workovers and abandonment) and Subsurface (geoscience, reservoir engineering, production engineering). He has spent over 13 years working on various decommissioning projects across the world focusing on the largest single element of cost: the plugging and abandonment of wells. This experience has covered actual field decommissioning projects, P&A planning, new technology, decommissioning deferment justifications, mature field asset trading and training for both engineers and non-technical staff.

Over the last 7 years, he has developed and delivered two distinct well decommissioning courses which have been provided in the UK and Danish sectors of the North Sea for a variety of field operators, service companies and governmental organisations.

Since 2019, he has delivered 4 Well P&A training sessions in Malaysia with customised contents to suit best with the regulations and operations in the region. The sessions were participated by major Oil & Gas operators and service providers namely PETRONAS Carigali, Repsol, EnQuest, Halliburton, Archer, Superior Energy, Vantage Energy and Uzma Berhad.

He is a UK Chartered Engineer (CEng) and a Fellow of the Institute of Materials, Mining and Minerals (FIMMM). He is also registered as a European Engineer (EurIng) and is a member of both the Institute of Directors (MIoD) and the international Society of Petroleum Engineers.
