E-451 - Well Productivity & Reservoir - Wellbore Interface

5 days PRO/PPLCTE
Level
Foundation
Audience
  • Young engineers involved in drilling/completion, supervisors in charge of drilling pay zone, and production professionals concerned with well productivity.
Purpose
  • This course provides the knowledge and skills needed to optimize the reservoir-wellbore interface and well productivity.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • select a reservoir-wellbore interface adapted to the conditions encountered in the reservoir,
  • detect problems holding down productivity and select adequate solutions.
Prerequisite
  • No prerequisites for this course.
Ways and means
  • Numerous exercises on the influence of key parameters.
  • Numerous animations and videos.
  • Summary notes prepared and presented by the participants.
  • Application to a real case (project) for the participants in the “Drilling and Completion Engineering” training course (E-412C).

NECESSARY FUNDAMENTALS OF RESERVOIR ENGINEERING FOR COMPLETION 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 0.5 day
  • Completion: operations involved, main phases.
  • Main factors influencing completion design.
  • Completion configurations: fundamental requirements, main configurations.
WELL PRODUCTIVITY - Part 1 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.
RESERVOIR WELLBORE INTERFACE IMPLEMENTATION (excluding “wellbore treatments”) 1 day
  • 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 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.
