N942 Gas Condensate Reservoir Engineering including HPHT

Course Facts

Course Code:
5 days
4.0 Continuing Education Units
40 Professional Development Hours
Certificate Issued Upon Completion


This course enables participants to develop skills to analyse and manage gas condensate reservoirs. It draws on Heriot-Watt’s world leading expertise and addresses: phase behaviour; relative permeability varying with velocity and interfacial tension; material balance equations; well productivity and pseudo-pressure calculation for different completion strategies, condensate banking and gravity drainage; practical fluid and flow simulation models; and demonstrating NeW-COIN software.

Duration and Training Method

Five days, classroom based, with micro-model reservoir condition flow visualization videos, lab visit, practical field and worked examples, hands-on exercises and discussion. Lectures supported and illustrated by exercises and multi-stage case studies. Participants are encouraged to bring issues associated with their own reservoirs for discussion.

Participants will learn to;

  1. Assemble an in-depth undertsanding of fluid and flow behaviour of gas condensate systems.
  2. Evaluate, select and apply the appropriate methods for analysing gas condensate reservoirs.
  3. Apply the appropriate well and reservoir models for analysis.
  4. Assemble the well and reservoir data needed for analysis.
  5. Perform realistic well performance predictions for different completion strategies.
  6. Formulate and recommend well and reservoir management actions.

Prerequisites and linking courses

 A good general knowledge of reservoir engineering is assumed through your own work, or having attended N933: Reservoir Engineering Fundamentals. As a potential follow on class, the N936 class (Reservoir Engineering Principles and Practice) is ideally suited for those having taken this class.
