GOSP Operating Plan Using Historical Data for Proactive Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing process facilities, such as gas-oil separation plants (GOSPs), often operate in a reactive manner, leading to inefficiencies due to unneeded resource consumption and delays in adjusting to changing demand, which can hinder effective processing of incoming production fluid.
Innovation Solution
A proactive operating method is implemented, using historical operational data to predict future operational characteristics and generate an operating plan that specifies the number of gas turbines, HRSGs, and fuel gas consumption, allowing for proactive resource management and optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If process facilities operate in a reactive manner based on current operating conditions, then operators can make immediate adjustments to current demand, but resource consumption increases and efficiency decreases due to unneeded components running
Solution Approach 1:
The system performs preliminary actions by predicting future operational characteristics and proactively adjusting the number of gas turbines, HRSGs, and boilers before the increased demand occurs. This allows the facility to be ready for anticipated demand changes without running excess components during periods of lower demand, thereby reducing fuel gas consumption while maintaining operational responsiveness.
2Adaptability or versatility
If process facilities operate in a reactive manner, then current operational flexibility is maintained, but delays occur in bringing components on line to meet increasing demand
Solution Approach 1:
The system predicts future operational characteristics and proactively adjusts the number of operational components before the demand increase occurs. This preliminary action eliminates delays in bringing components on line while maintaining operational flexibility, as the system is already prepared with the appropriate number of components running when the anticipated demand materializes.
3Reliability
If more gas turbines, HRSGs, and boilers are operated to ensure sufficient capacity, then demand can be met, but resource consumption and operational inefficiency increase
Solution Approach 1:
The system predicts future operational characteristics and proactively adjusts the number of gas turbines, HRSGs, and boilers before the demand increase occurs. This ensures sufficient capacity is available to meet demand while avoiding the operational inefficiency of running excess components during periods of lower demand, thereby maintaining both reliability and productivity.
4Loss of energy
If fewer components are operated to reduce resource consumption, then efficiency improves, but the facility cannot meet increasing demand when it occurs
Solution Approach 1:
The system predicts future operational characteristics and proactively adjusts the number of operational components before the demand increase occurs. This allows the facility to operate with fewer components during periods of lower demand, reducing fuel gas consumption and improving efficiency, while ensuring sufficient capacity is available when the anticipated demand materializes, thereby maintaining reliability.

AI summary
Provided are techniques for proactively operating gas-oil separation plant (GOSP) type process facilities that include determining historical operational characteristics of a GOSP for a past time interval using historical operational data for the GOSP, determining expected operating characteristics of the GOSP for a subsequent time interval using the historical operational characteristics, determining an operating plan for the GOSP using the expected operating characteristics, and operating the GOSP in accordance with the operating plan.
