METHODS FOR REDUCING THE PRECIPITATION PROPENSITY OF ASPHALTENES IN BLENDED CRUDE OILS

摘要

Methods for selecting crude oils to prepare a crude oil blend. A precipitation propensity of a first crude oil and a precipitation propensity of at least one second crude oil can be measured. At least one of the first crude oil and the second crude oil can include asphaltenes. The precipitation propensity of the first crude oil can be multiplied by a proposed volume percent of the first crude oil in a proposed crude oil blend to provide a first value. The precipitation propensity of the second crude oil can be multiplied by a proposed volume percent of the second crude oil in the proposed crude oil blend to provide a second value. A composition of the proposed crude oil blend can be modified if a sum of the first value and the second value is less than a predetermined cutoff.
