Well Engineering and Production > Fundamentals of Gas Well Deliquification – Virtual Instructor Led Training (VILT)

About this Virtual Instructor Led Training (VILT)

Gas well performance is dictated by the combination of inflow and outflow performance. The outflow performance of any gas well is at risk as soon as the gas rate becomes insufficient to lift the associated liquid water and condensate to surface. This condition is referred to as liquid loading and invariably causes intermittent production and significant loss of well capacity and reserves.

Liquid loading can be mitigated by different types of gas well deliquification such as compression, velocity string, plunger lift, foam-assisted lift, gas lift and downhole pump. This 5 half-day Virtual Instructor Led Training (VILT) course will first show how to predict and recognize liquid loading. Next, it will describe how to select, design, install and operate the best sequence of deliquification measures. It will also consider deliquification in the presence of other production threats such as water production and halite blockage. These topics will be illustrated by an abundance of field examples and case studies.

Participants will be completing a case study during the VILT training. This case study is preferably based on their own relevant data set. If no such data is available, an external data set will be provided instead.

Prerequisites skills:

It is necessary for participants to have a basic knowledge of petroleum engineering and gas well performance.

On completion of this VILT course, participants will be able to:

  • Develop skills and tools to understand and model gas well liquid loading and deliquification
  • Understand the principles and practicalities of different deliquification methods
  • Learn how to compare, select and apply deliquification measures by taking own field case as example

This VILT course is intended for production engineer, surveillance engineer, completion engineer, production/process chemist, reservoir engineer, production programmer, production operator as well as professionals responsible for selecting, installing, operating, monitoring and optimizing deliquification.

  • Basic or Foundation

This VILT course utilizes Excel worksheets first introduced in the Optimising Gas Well Performance VILT course. To derive maximum learning value, participants are requested to bring their own relevant set of field data to complete their own case study during the training. The list of data required will be shared beforehand so data can be timely collected and cleared for external use. Participants should be prepared to complete any unfinished exercises and assignments before next day’s session starts. The instructor will be available to discuss any remaining queries after the completion of the VILT course.

This VILT will be delivered online in 5 half-day sessions comprising 4 hours per day, with 2 breaks of 10 minutes per day. Course Duration: 5 half-day sessions, 4 hours per session (20 hours in total).

Your expert course leader brings with him 35 years of oil and gas field experience within Shell of which 25 years as gas well production engineer. He has covered the full spectrum of activities moving from R&D to green field development to brown field surveillance and optimisation, to become a leading gas well performance and deliquification specialist.

He likes to capture the complex reality of gas well inflow, outflow and reservoir performance by means of practical data-driven rules and tools that cover a wide range of conditions i.e. shallow-to-deep, prolific-to-tight, dry-to-wet, green-to-brown, 1-1/2”-to-9-5/8” tubing, and depletion-to-aquifer drive.

Before his retirement in end 2020, he worked for various Shell affiliated oil and gas companies including Shell Malaysia, Petroleum Development Oman, NAM Netherlands and Shell R&D in Netherlands and USA.

To further optimise your learning experience from our courses, we also offer individualized “One to One” coaching support for 2 hours post training. We can help improve your competence in your chosen area of interest, based on your learning needs and available hours. This is a great opportunity to improve your capability and confidence in a particular area of expertise. It will be delivered over a secure video conference call by one of our senior trainers. They will work with you to create a tailor-made coaching program that will help you achieve your goals faster.
