Drilling & Completion - Wellbore interface & Well Productivity
WELPROD-EN-P
Who should attend?
This course provides a comprehensive and practical understanding of fundamentals of drilling, completion, wellbore interface and well productivity applied to reservoir engineering concerns.
Public :
Newly-hired and 2- to 3-year experienced reservoir engineers willing to deepen their knowledge in reservoir fluid properties and PVT modeling; geoscientists, petroleum engineers and production engineers moving towards reservoir engineering.
Prerequisite :
Degree in reservoir engineering or petroleum engineering.
No experience required.
Course Content
FUNDAMENTALS OF DRILLING
Well design. Casing program.
Drilling equipment and techniques.
Directional drilling.
Drilling fluids (mud).
Different types of rigs. Specific offshore problems.
FUNDAMENTALS OF COMPLETION
Completion: operations involved, main phases.
Main factors influencing completion design.
Completion configurations: fundamental requirements, main configurations.
WELL PRODUCTIVITY (Part 1)
Fundamentals: overall approach of the well flow capacity.
Inflow (study of the bottom-hole pressure from the upstream side):
Main parameters, Productivity Index (PI), global skin and flow efficiency.
Outflow (study of the bottom-hole pressure from the downstream side):
Case of oil wells and case of gas wells.
Analysis of inflow and outflow performance curves, need for artificial lift.
Specific aspects linked to drilling and cementing the pay zone.
Perforating: main techniques, key parameters for productivity.
Specific case of horizontal drains.
WELL PRODUCTIVITY (Part 2)
Additional information about Productivity Index (PI):
Productivity Index and flow regime.
Inflow performance below bubble point pressure (IPR).
Additional information about skin:
Components of completion skin.
Damage skin estimation.
Learning Objectives
Upon completion of the course, participants will be able to:
describe main drilling equipment and operations,
describe main completion equipment, operations and configurations,
describe main concepts of reservoir-wellbore interface and choose an interface adapted to the conditions encountered in the reservoir,
discuss main concepts of wells productivity, included inflow, outflow and skin, detect problems holding down wells productivity and select adequate solutions.
