Ensuring Well Integrity in Changing Environments

1 – 4 March 2015

Brisbane, Australia

About this workshop

Abstract

Designing, maintainin,g and demonstrating well integrity across the life of the well is imperative to a sustainable oil and gas industry. This workshop intends to cover the significant challenges well integrity presents to petroleum professionals and regulatory authorities every day.

Subsea, HPHT, geologically complex reservoirs, high CO2, aquifer protection, and sensitive stakeholders represent significant challenges throughout drilling, completion and production. Some contributors to compromised well integrity can include factors such as wellbore instability, corrosion, cement bond deterioration, expansion/contraction, and changing pressure envelopes.

It is vital for the sustainability of the industry that production is optimized and operating costs reduced through a comprehensive understanding of reservoir characteristics, careful well design and construction, continuous monitoring and suitable workovers. Some of the specific challenges facing our industry include:

  • Aquifer protection through effective zonal isolation for CSG wells
  • Temperature changes on annuli in HPHT wells
  • Corrosion control for high CO2 wells
  • Abandonment / decommissioning challenges for legacy wells
  • Sustainable well design for subsea wells (annular pressure)
  • Flow assurance of high rate wells (erosion control)
  • Demonstrating environmental protection in a sensitive stakeholder setting
  • Unconventional / Basin Centred Plays and subsequent cost pressures
  • Impact of hydraulic fracturing on cement / cement design and casing design
  • Managing well integrity on a large scale (CSG and shale)

Benefits of Attending

  • Appreciate industry colleagues’ different approaches to well integrity issues
  • Hear from industry leaders on new technologies to support well integrity management
  • Exposure to alternative approaches to life-of-well integrity management
  • Understand government regulatory demands and recommended best practices

Objectives

This workshop will provide a platform for oil and gas professionals to network and share applications, technologies and practices currently undertaken in an effort to ensure and improve well integrity. Key topics and issues that will be tabled include:

  • Latest technology, procedures, software and systems for integrity issues
  • Barrier types, qualification and assurance over the well life cycle
  • Case studies of complex well casing and trapped annular pressures
  • Innovative approaches to well decommissioning

Who Should Attend

Well integrity challenges petroleum professionals who are engaged in design and construction of the well, drilling, completions, production, abandonment and intervention. This workshop intends to appeal to an inter-disciplinary audience and hopes to draw upon the varied information, ideas, and technologies from the likes of:

  • Engineers, superintendents and managers in drilling, completions and well services
  • Petroleum, production, reservoir, cement and well integrity engineers
  • Intervention and abandonment specialists
