Solution Approach 1:

The patent enables optimization to be performed before wells are put into production by using historical well data and predictive modeling. The system can calculate expected gas blend parameters and optimize well rates in advance for future production scenarios, allowing operators to prepare optimization strategies before actual production begins, thus eliminating the need for post-hoc adjustments.

Solution Approach 1:

The patent implements an iterative optimization process where the system calculates gas blend parameters based on current well rates, compares them against targets, and automatically adjusts well rates accordingly. This feedback loop continues until targets are met, with each iteration bringing the blend closer to specifications. The automated feedback mechanism manages complexity by systematically reducing the search space through guided adjustments rather than random trials.

Inventive Principle:

AI summary

Described is a method for gas blend optimization. The method includes assigning a target rate for one or more parameters of interest in a desired gas blend. Data related to the parameters of interest is obtained for each well of a geographical region of interest. Based on the obtained data, an effect of each well's contribution to the parameters of interest in a total gas produced at a gas processing facility is determined. The parameters of interest in the total gas produced are optimized until the assigned target rate is met by determining an adjusted well gas rate for each well in a list of wells selected based on their effects on the total gas produced.
