E-455 - Wellbore Treatments

5 days PRO/TRAITE
Level
Foundation
Audience
  • Drilling or completion engineers, supervisors, lab or production professionals, non-specialists in wellbore treatment.
Purpose
  • 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.
Prerequisite
  • No prerequisites for this course.
Ways and means
  • Animations - Exercises.
  • Visit of a rock mechanics and reservoir-wellbore interface laboratory.
  • Application to a real case (project) for the participants in the “Drilling and Completion Engineering” training course (E-412C).
Observation
Kindly refer to the following complementary courses which might be of interest: “Matrix Acidizing” (E-456) and “Basic Hydraulic Fracturing”(E-457).

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, …
