Ever increasing demands related to cost savings and efficiency improvement require that the existing as well as planned oil and gas production assets are fully and optimally utilized. Nodal or Systems Analysis approach allows selection of optimum components under varying field and reservoir conditions. The course provides practical instructions on design and analysis of naturally flowing oil and gas wells, as well as gas-lift and ESP systems based on nodal or systems analysis concepts.

Knowledge Takeways
- Provide an awareness of the fundamentals of production by introducing fluid flow, flow correlations, PVT/Black Oil, and discussing the inflow performance relationship (IPR), vertical lift performance (VLP), nodal analysis, and pressure gradient curves.
- Explain major factors in the artificial-lift selection process
- Analyze cessation of the natural flowing period of an oil well. Identify conditions in which a gas well ceases to flow because of liquid loading
- Identify components of a gas-lift and an ESP system. Design and analyze gas-lift and an ESP system.
-
Use software tools to:
- Develop a well model for a well under naturally flowing, gas-lift, or ESP conditions
- Conduct sensitivity analysis on various components of well system for a robust design
- Adjust input parameters based on field measurements.
Who should attend?
- Well analysts, artificial-lift engineers, production engineers, and other technical personnel who are involved in the analysis and design of naturally flowing oil wells, gas wells, and high-rate artificial-lift systems, such as gas-lift and ESP systems.
Prerequisites:
- Understanding of basic petroleum engineering concepts. Attendees should have petroleum engineering background or at least five years of working experience in the industry.
- For 3-5 days classes: Each participant needs to bring a laptop for solving class examples using software to be provided during class. Laptop needs to have a current Windows operating system and at least 500 MB free disk space. Participant should have administrator rights to install software.
