Audience

    • Drilling or completion engineers, supervisors, lab or production professionals, non-specialists in wellbore treatment.

Level

  • Foundation
  • This course provides knowledge and skills needed to examine well damage issues and take appropriate actions.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • identify the nature and the origins of well damage,
  • choose the adequate stimulation method,
  • learn how to deal with sand production and water coning.
Course Content

INTRODUCTION TO WELLBORE TREATMENTS

1 day

  • Fundamental reminders on Productivity Index (PI), the skin effect and flow efficiency, the different components of the skin.
  • Productivity issues: cause of low productivity, nature and origins of well damage, location of problems and possible solutions.
  • Damage due to fluids: mechanisms, prevention.

MATRIX TREATMENT: ACIDIZING…

1 day

  • Aims; how it works.
  • Carbonate rocks and sandstones; inner characteristics, reactivity to injected fluids.
  • Choosing the acids and the additives.
  • Choosing the wells to be treated.
  • Design: preparation, checks and guidelines during the operation, after the acidizing (flow back…), possible cause of failure, coiled tubing…

HYDRAULIC FRACTURING

1 day

  • Aims and principles; candidate wells.
  • Frac fluids and fracture propping.
  • Calculation models and frac impact on PI.
  • Design; program, frac evaluation.
  • Other cases: pre-frac, minifrac, acid frac.

SAND CONTROL

1 day

  • Basics: consequences of sand, prediction of sand, sand analysis.
  • Sand control techniques; case of mechanical processes (determining the gravel and the screens…).
  • Design: cased hole gravel packing, openhole gravel packing, preparing the gravel pack, various methods, guidelines.
