Course Content
NECESSARY FUNDAMENTALS OF RESERVOIR ENGINEERING FOR COMPLETION
-
Duration : 1 Day
Main parameters about the rock-fluid couple: porosity, permeability, saturation.
Means of reservoir knowledge: core, logging, well test.
PVT study: PV diagram, PT diagram, terminology (bubble point, dew point, Rs, Bo, Bg, GOR, WOR…).
Drainage mechanisms: primary, secondary and enhanced recovery.
COMPLETION FUNDAMENTALS
-
Duration : 0.5 Day
Completion: operations involved, main phases.
Main factors influencing completion design.
Completion configurations: fundamental requirements, main configurations.
Main completions of gas storage wells and Geothermal wells
WELL PRODUCTIVITY (Part 1)
-
Duration : 1 Day
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)
-
Duration : 1 Day
Additional information about PI:
Productivity index and flow regime.
Inflow performance below bubble point pressure (IPR).
Additional information about skin:
Components of completion skin.
Damage skin estimation.
