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

Disciplines: Production and Operations

Course Description

The course focuses on challenges and issues of proper isolation in wells with specific interest in finding weaknesses in well construction prior to creating problems during perforating, acidizing, fracturing or other high pressure operations.  Case histories are used to illustrate warning “flags” of well damage or weaknesses created by such factors as corrosion, erosion, explosive stress loads, packer setting, drilling wear, differential pressure, various chemical attacks, thermal effects, cement failure and other conditions.  Problem avoidance will be emphasized.

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

1 Day

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

Foremen, technicians, and engineers with less than five years in stimulation or well construction.


0.8 CEUs (Continuing Education Units) are awarded for this 1-day course.

George E. King is a registered professional engineer with over 43 years of experience since starting with Amoco Production Research in 1971. His technical work has provided advances in foam fracturing, production from unstable chalk, underbalanced perforating, sand control reliability, gas shale completions and fracturing. Currently, he is working with new technologies for the oil and gas industry.

King has written 71 technical papers and was awarded the 2004 SPE Production Operations Award and the 2012 Engineer of the Year Award from the Houston Region of the Texas Society of Professional Engineers. He is Apache Corporation’s Distinguished Engineering Advisor.

King holds a BS  in chemistry from Oklahoma State (1972), a BS in Chemical Engineering from University of Tulsa (1976) and a MS in Petroleum Engineering from University of Tulsa (1982), where he also taught completions and workovers for 11 years as an adjunct professor.
