Well Productivity & Reservoir - Wellbore Interface

COMP/PPLCTE

Who should attend?

  • This course provides the knowledge and skills needed to optimize the reservoir-wellbore interface and well productivity.
Audience :
  • Young engineers involved in drilling/completion, supervisors in charge of drilling pay zone, and production professionals concerned with well productivity.

Level : Foundation

Course Content

  • NECESSARY FUNDAMENTALS OF RESERVOIR ENGINEERING FOR COMPLETION

      • 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

      • 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.
  • RESERVOIR WELLBORE INTERFACE IMPLEMENTATION (excluding “Wellbore treatments”)

      • 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 PI:
      • Productivity index and flow regime.
      • Inflow performance below bubble point pressure (IPR).
      • Additional information about skin:
      • Components of completion skin.
      • Damage skin estimation.
  • KNOWLEDGE ASSESSMENT

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.

Ways & 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 & Completion Engineering” training course.
