Abstract
Carbon dioxide flooding is a common IOR method employed in fields which have relatively easy access to CO2. In some cases, estimating the CO2 injection rate is the most important design parameter which decides the planning, field implementation and eventual success of a flood. This paper presents a method for evaluating this important parameter from data that should be readily available for a field. Water injectivity index values from fields which have undergone waterflood operations are compared to injectivity index values for the same field while undergoing CO2 flood operations. Different methods for evaluating the indices are presented as is a process for estimating the CO2 injectivity value from data from secondary operations. The correlation developed has been verified on injectors which were converted in the same field. Initial injection rates calculated from this correlation were in closer agreement to actual injection rates than those predicted by other theoretical formulas.
