E-451 - Well Productivity & Reservoir - Wellbore Interface

  • Young engineers involved in drilling/completion, supervisors in charge of drilling pay zone, and production professionals concerned with well productivity
  • To provide the knowledge and skills needed to optimize the reservoir-wellbore interface and well productivity
Learning Objectives
  • To choose a reservoir-wellbore interface adapted to the conditions encountered in the reservoir
  • To detect problems holding down productivity and select adequate solutions
Ways and means
  • Numerous exercises on the influence of key parameters
  • 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-412)

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
