Business Impact: Participation in this course will provide attendees a basic to skilled application level working knowledge of artificial lift and related production issues for multi-well pads in unconventional and tight resource plays. Dynamic nature of unconventional reservoirs causes production instabilities, increased downtime, sub-optimal operations and higher equipment failures. This course teaches proper selection and operation of artificial lift that directly impact business bottom line by improving production, minimizing downtime, reducing lease operating costs, and avoiding deferred production.
Production optimization is also discussed, particularly real-time measurements and optimization techniques that are required to understand and manage the dynamic production scenarios. Besides the basics of artificial lift and real-time measurements, the training focuses on specific production and lift challenges related to the unconventional wells.
Duration and Training Method
This is a classroom or virtual classroom course comprising a mixture of lectures, discussion of case studies, worked examples, and hands-on exercises.
Participants will learn to:
- Formulate a problem statement and solution plans for production from unconventional and tight resource plays
- Compare, contrast, and categorize various forms of artificial lift systems
- Analyze the need for artificial lift systems in unconventional plays
- Differentiate production and artificial lift challenges in unconventional from conventional assets
- Assess the strengths and weaknesses of artificial lift methods in unconventional plays
- Contrast artificial lift needs of liquid-dominated plays versus gas-dominated production
- Understand the impact of artificial lift on the development of multi-well pads
- Learn about advances in real-time approaches to the production monitoring and lift management
- Estimate life cycle plans for artificial lift in unconventional plays
