Abbas Delavar, UK

Abbas studied Petroleum Engineering in Abadan Institute of Technology, Iran. His BSc thesis was on 'Applications of Artificial Neural Networks in Petroleum Engineering'. He graduated with a Masters degree in Petroleum Engineering from Delft University of Technology, in the Netherlands. His thesis was on 'Interfacial Science and Wettability'. In 2009, Abbas joined BP as a Production Engineer for Southern North Sea Gas assets, involved in several appraisal studies and designing of operations for gas well deliquification. He currently works as a Petroleum Engineer in Central North Sea oil fields, investigating and progressing several well intervention, working over projects, and would like to continue supporting other assets in deliquification operations.


Liquid Loading and Gas Well Deliquification

Liquid loading of a gas well results from the inability of the produced gas to remove the liquids from the wellbore. This phenomenon has a significant impact on well production rate, operational efficiency of the installation and possibly, integrity of the production facilities. A large proportion of the gas wells around the world are impacted by this issue and several techniques have been developed to mitigate it. These techniques are generally called 'deliquification' in the upstream oil and oil gas industry.
This lecture will briefly explain why liquid loading occurs in a gas well and how understanding of its principles has helped in the development of different deliquification techniques. The advantages and disadvantages of each technique are also briefly presented.
