Well Integrity Management: A Deepwater Approach

7 – 8 November 2012

Salvador, Bahia, Brazil | Pestana Bahia Hotel


Technical Agenda

Wednesday, 7 November, 0830–0900

Keynote Speaker: Jackson Burjack Farias, Petrobras


Session I: Well Integrity Management During Well Design and Construction

Chairpersons: Alexis Garcia, NOV; Rubén Beltran, Weatherford

Well integrity management over the well lifecycle begins at the initial planning stage for each project. Wells must be designed as a system, and the workflow and processes should be developed and taken into consideration early on. This management system should be continuous throughout the well lifecycle and project. Careful consideration should be given to information management, and critical variables should be defined and controlled since the pre-drill stage. Project management software should fit seamlessly within the system. Some of the topics for this session are:

  • Full management of the well lifecycle
  • Information management (handover)
  • Control of critical variables
  • Specific software/modeling

Speaker 1: Steve Hobart, Halliburton
“Wellbore Integrity Challenges in Near-Salt Rubble Zones”

Speaker 2: Chris Hanley, NOV
“Application of Predictive Drilling Models to Assist in the Construction of a Successful Borehole for the Entire Well Lifecycle”

Speaker 3: Frank Fornasier, Halliburton
“Advances and Customization of High Performance Water-Based Drilling Fluids for Enhanced Wellbore Stability – Brazil Experience”


Session II: Well Integrity Management During Well Maintenance and Production

Chairperson: Fernando Bertomeu, SINOPEC Argentina

After a well is drilled and completed, oil and gas production can go for decades. During this period numerous interventions will be performed for maintenance, change of old equipment and installation of new tools. This session will address the challenges to keep the well integer during its production life as well as while necessary intervention is taking place.

Speaker 2: Randy Romman, Weatherford, “Justifying Re-Completions in Mature Fields with Solid Expandable Cased Hole Liners”

Speaker 3: Humberto de Lucena Lira, Petrobras, "Risk Analysis of the Wells in Shallow Water of the Sergipe-Alagoas Basin Equipped with Subsea Christmas Tree"


Session III: Well Integrity Management during Plug and Abandonment

Chairpersons: Juan Sanguedolce, Baker Hughes; Marcos Albuquerque, Schlumberger

Plug and abandonment of wells, either in a temporary or definitive fashion, is of utmost importance. An abandoned well has significant less monitoring than a producer, even more so in the case of offshore deepwater wells. Making sure that integrity is acquired during and after abandonment operations is a must for the oil industry.

Speaker 2: Hélio Alves Pedrosa Júnior, Baker Hughes, "Zonal Isolation – Set for Life Cementing Systems"

Speaker 3: Alejandro Daens, YPF, “Supplementary Casing, Results in Canadon Seco Field”


Session IV: New Standards and Regulations

Chairpersons: Einar Molnes, ExproSoft AS; Fernando Bertomeu, SINOPEC Argentina

Recent industry accidents and blowouts have caused regulators around the world to initiate work related to updating rules and regulations related to safety and well integrity. This session will provide an overview and status description on relevant international standard and national standards/guidelines in the well integrity area which have gained industry wide acceptance and relevance. Furthermore, this session will address recent and forthcoming regulatory changes in the well integrity are which have been initiated to capture experiences and lessons learned from recent major accidents related to loss of well control in the industry.

Speaker 1: Michelle Monteau, Statoil, "Norsok D-010—A Glimpse Into Potential Changes With Revision 4 and How We Use It"

Speaker 2: José Roberto Ferreira Moreira, Petrobras, "New ISO-Standard on Well Integrity During Production Operations"

Speaker 3: Simone Carvalho, Halliburton Landmark , “Barrier Assurance Monitoring – Improve Safety and Ensure Legal Compliance”


Networking Reception sponsored by NOV

Thursday, 8 November


Keynote Speaker: Neal Adams, Consultant, "The Future of Deepwater Blowout Control"


Session V: New Technologies

Chairpersons: Alexis Garcia, NOV; João Carlos da Luz, OGX

Industry best practices have evolved and improved continually over the years, but new technologies from other industries or novel ideas within the upstream segment of the petroleum industry could accelerate the learning curve. This session will focus on examples of such technologies that can be integrated to provide more robust integrity of oil and gas wells. Some topics to be discussed are:

  • Lessons learned
  • Case histories
  • Challenges and Solutions
  • New developments

Speaker 1: Roberto Zerkowski, NOV, "Safer Well Integrity Management Through Better Downhole Monitoring"

Speaker 2: Einar Molnes, PTC, " A Holistic Approach to Well Integrity Management"

Speaker 3: Leonardo Lopes, M-I SWACO, "Ultra Heavy Weight Synthetic Base Fluid Designed for HPHT/Pre Salt Scenario in Santos Basin Prospect"


Session VI: Well Integrity Issues for Deepwater Operations

Chairperson: Heitor Lima, Petrobras;Roberto Zerkowski, NOV

Recent catastrophic well integrity/control incidents in deep waters around the world have led to many operational changes and many more new challenges for the Oil & Gas industry. Prevention is the only solution to avoid catastrophic incidents as those from the recent past. The solution resides in good well integrity management throughout the whole life cycle: design, drilling and completion, production, interventions, workover, and finally abandonment. An example would be the design and testing of a subsea completion string able to safely withstand fracturing operations.

At the other end of the life cycle, older wells frequently suffer from well integrity problems due to erosion, corrosion, and fatigue. Well integrity management is essential to develop oil and gas resources profitably while minimizing health and environmental effects. Particularly in deepwater operations, loss of critical safety barriers can lead to exceedingly high costs for diagnosis and remediation, which can have a devastating effect on the operator’s economic future.
