Who should attend?

  • This course provides the practical, comprehensive understanding and skills needed to master well performance on shale gas plays and make significant contributions to field productivity studies and well performance monitoring.
Public :
  • Reservoir, well performance or production engineers and technicians.

Level :Knowledge

Prerequisite :
  • Basic knowledge of the use of PROSERT™ software.

Course Content

  • INTRODUCTION TO PRODUCTION SYSTEM - Duration : 0.25 Day

      • Introduction to well performance nodal analysis: inflow x outflow.
      • Overview of PROSPER™ software workflow:
      • PROSPER™: building initial well system file.

  • PVT DATA/PVT MODELING - Duration : 0.5 Day

      • Gas PVT properties.
      • PROSPER™: building PVT model for shale gas well.

  • SHALE GAS PLAYS PROPERTIES & WELLBORE INTERFACE - Duration : 0.75 Day

      • Shale gas systems characterization- dual porosity, stress dependent permeability, gas desorption.
      • Shale gas completion stimulation (hydraulic fracturing).
      • Introduction to well performance analysis of unconventional gas reservoirs.
      • Effect of productivity parameters for horizontal wells (length, wellbore radius, permeability ‘’anisotropy’’, thickness vs. position ‘’Well Eccentricity’’, drainage area, formation damage ‘’Skin’’).
      • Derivation of analytical solutions.

  • INFLOW PERFORMANCE/IPR MODELING - Duration : 1.25 Days

      • PROSPER™: fractured horizontal well modeling.

  • WELLBORE FLOW, OUTFLOW PERFORMANCE/VLP MODELING - Duration : 1 Day

      • Fundamentals of multiphase flow: gas-liquid flow, flow regimes (sub vertical, deviated, horizontal wells).
      • Minimum flow rate/gas well loading (pressure drop through a horizontal well for gas flow, effect of the well geometry TOE up, TOE down).
      • Pressure gradient and Vertical Lift Performance (VLP) curves.
      • Tubing head pressure, tubing ID impacts:
