About this Virtual Instructor Led Training (VILT)
Gas wells are the most challenging part of gas production systems. Their performance must be monitored to validate and update the production forecast and reserves estimate, and to provide an early warning for significant changes in inflow or outflow. Also, their performance must be managed to review and mitigate threats of inflow and outflow, and to identify and mature remaining opportunities to boost production and reserves.
To monitor and manage gas well performance, you need to understand and model gas well inflow and outflow as function of well, reservoir and surface parameters, identify and model measures that can restore, sustain or improve inflow and outflow performance, and select and justify such measures based on technical and economic arguments.
This Virtual Instructor Led Training (VILT) not only serves the surveillance and capacity needs of existing gas wells but also the design requirements of new gas wells.
- Recognise and model gas inflow, outflow and surface well performance
- Understand and model gas well reservoir performance, production forecast and reserves
- Identify and model gas well performance threats and opportunities
- Select and justify measures that mitigate those threats or realise those opportunities
- Introduce well review process
This VILT course is intended for gas well production engineers, surveillance engineers, completion engineers, reservoir engineers, production programmers, and production operators.
The VILT course consists of a series of lectures followed by practical exercises. The lectures are interactive with field examples that illustrate concepts and promote discussion. Participants are encouraged to contribute their own, hence most relevant, field examples. The exercises make use of a series of Excel worksheets for back-of-the-envelope calculations. This VILT course will show that simple Excel tools are sufficient to generate ballpark answers. However, if participants require more detailed solutions, they may wish to consider using a dedicated gas well performance software such as PROSPER at their own expense. This software is currently not provided as part of the course.
The VILT course addresses ways and means to monitor and manage gas well performance. Participants will explore and practice these ways and means using the same Excel worksheets, and are invited to implement their own field specific data. The VILT course also provides the technical background of measures that sustain and improve gas well inflow and outflow performance.
The VILT course introduces essential skills and tools for the periodic review of gas well performance. Such well reviews support the yearly update of production forecast, reserves, surveillance plan and capacity plan.
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.
