摘要
Methods and systems are presented in this disclosure for detection of crossflow and quantification of crossflow effects on fluid distribution during multistage injection treatments of hydrocarbon bearing reservoir formations. A low rate injection stage is applied after a main (high rate) fluid injection stage of a multistage injection treatment process. Wellbore temperature measurements can be utilized along with an inversion process to detect any crossflow and quantify its effects on fluid distribution during the main injection stage. After the effects of any detected crossflow on the fluid distribution are quantified, the effectiveness of the multistage injection treatment can be analyzed and any adjustments or modifications to the treatment can be made accordingly.
