Evaluation of preexisting materials in a well is critical to ensure proper abandonment. For example, a cement sheath which is not providing zonal isolation would need to be addressed prior to abandonment. This session will focus on evaluation of materials in the well prior to any additional actions. Topics will include well logging, tracers, and other evaluation methods as well as their importance in long-term integrity with respect to well abandonment. 

Chairs: Lance Sollohub, Cudd Energy Services; Maggie Benge, Premier Corex

Annular isolation for well abandonment is typically a challenge due to the uncertainty of the annulus condition. This session will focus on these challenges and methods to overcome them. Topics will include annular access and tools to enhance, annular fluid displacement, annular losses and methods to control, as well as methods to provide circumferential cement coverage.

Chairs: Jeff Long, American Cementing; Laurent Delabroy, Aker BP

The use of alternative materials in cement systems continues to evolve as the industry learns from experience and invests in material science, all while managing cost pressures. While not new, gaps remain in assessing material suitability for abandonment operations and in defining qualification criteria set by regulators or operators. This session will highlight current alternative materials in use and offer insights and cautions for their future application.
