Claim 0:
1. A method comprising:
obtaining, by a computer processor, a real-time petrophysical data derived from a plurality of well logs during drilling;
utilizing, by the computer processor, the real-time petrophysical data to quantify a formation damage profile using a resistivity tornado chart and a wellbore modeling;
utilizing, by the computer processor, the resistivity tornado chart to determine a depth of invasion inside a formation at each depth in a wellbore by using ratios between different resistivity logs obtained while drilling;
creating, by the computer processor, a synthetic wellbore model by using a fluid flow equation for the wellbore modeling and calculating a time-specific invasion profile to determine a condition at a flowback time;
identifying a plurality of flowback candidates from the real-time petrophysical data based on reservoir management goals, wherein the plurality of flowback candidates include a core data, a well testing data, and a fluid saturation data for data correlation and process enhancement prior to calculating the time-specific invasion profile;
performing, by the computer processor, a computational fluid dynamics investigation in order to identify invaded fluid flow characteristics from the formation to the wellbore;
calculating, by the computer processor, a duration needed to flowback an obtained invaded volume for removal of the formation damage based on a fluid flow behavior near the wellbore, and
performing, based on the calculated duration, flowback of the wellbore to clean flow conduits near the wellbore and enhance performance of the wellbore.
