Who should attend?

  • This course provides knowledge and skills needed to identify well damage issues in sandstone and carbonate reservoirs, and design acidizing programs.
Public :
  • Drilling or completion engineers, supervisors, lab or production professionals, non-specialists in wellbore treatment.

Level : Proficiency

Course Content

  • INTRODUCTION TO RESERVOIR TREATMENTS

      • Fundamental reminders on the Productivity Index (PI), the skin effect and flow efficiency, the different components of the skin.

  • FORMATION DAMAGE

      • Productivity issues: cause of low productivity, nature and origins of the damage, location of the problems and possible solutions.
      • Scale deposition: scale control and prevention.

  • MATRIX TREATMENT: ACIDIZING CARBONATES

      • Aims; how it works.
      • Sandstones: inner characteristics, reactivity to injected fluids.
      • Laboratory studies.
      • Exercises.

  • MATRIX TREATMENT: ACIDIZING SANDSTONES

      • Aims; how it works.
      • Sandstones: inner characteristics, reactivity to injected fluids.
      • Choosing the acids.

  • ACIDIZING ADDITIVES

      • Review of the different additives (corrosion inhibitor, iron complexing agents, surfactants, solvents, etc.).
      • Selection of the additives.

  • MATRIX TREATMENT DESIGN

      • Candidate selection.
      • Matrix design methodology.
      • Diversion.
      • Treatment evaluation.
      • Other associated processes (water shut-off…).
      • Causes of failure in matrix acidizing.
      • Case study.

  • KNOWLEDGE ASSESSMENT

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • identify the nature and the origins of well damage,
  • design an acidizing program,
  • select the additives needed,
  • set up the acid treatment program.

Ways & Means

  • Exercises - Teamwork.
  • Visit of a reservoir-wellbore interface laboratory (if available).
