Gas Condensate Reservoir Engineering including HPHT
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.
Schedule
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.
