Abstract
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.
