Production Optimalization Using Nodal Analysis

Production Optimalization Using Nodal Analysis

Description :

The chief function of a system-wide analysis is to increase well rates. It identifies bottlenecks and serves as a framework for the design of efficient field wide flow systems, including wells, artificial lift, gathering lines and manifolds. Together with reservoir simulation and analytical tools, Nodal analysis is used in planning new field development. Many factors are used to maximize production from discovery wells to those ready to be abandoned, including: establishing a relationship between flow rate and pressure drop within each component in the system; using gradient correlations and selection procedures; and deciding when to use artificial lift to maintain a required production rate.
This training is designed to develop participants skill on how-to optimize the completion design to suit the reservoir deliverability, identify restrictions or limits present in the production system and identify any means of improving production efficiency in production optimization of oil and gas wells using Nodal systems analysis and covers the use of multiphase flow correlations to determine flow rates and pressure traverses in flowing oil wells, gas-condensate wells, gathering systems, and pipelines.
