Well Integrity Impacts and Requirements for Fracturing and Acidizing in New and Old Wells (1/2-Day Version)

Disciplines: Production and Operations

Course Description

Hydraulic fracturing operations can place extreme pressure and erosive loads on wells, whether new or old. Well design, monitoring and maintenance requirements have changed significantly within the past three to five years and not all of the industry are knowledgeable of the potential for failures as these events occur as single entities or in concert.

Cyclic pressures during multi-stage fracturing in horizontal wells are a special case where repeated pressure application can potentially produce loads outside the safe operating envelope predicted by conventional well modeling software. This half-day course examines the principle stress and erosion producing events that can impact isolation containment and suggests methods of monitoring, control and even well design changes.

Learning Objectives:

  • Identification of main well failure problems with cause and typical extent of problems
  • Warning “flags” common to most damage causes
  • Workable and non-workable repair approaches
  • Pressure test types, extent and what they do and do not identify
  • Monitoring methods for stimulations

Learning Level


Course Length

Half-day (4 hours)

Why Attend

Ability to identify wells that may not be candidates for well stimulation or restimulation can prevent both economic and especially environmental problems.  These problems are often evident by quick screening, even by non-specialists.

Who Attends

Targeted audience is foremen, technicians, engineers with less than five years in stimulation or well construction.


0.4 CEUs (Continuing Education Units) are awarded for this half-day course.
