1. A method for determining flow distribution in a formation having a wellbore formed therein, comprising: positioning a sensor within the wellbore, wherein the sensor generates a feedback signal representing at least one of a temperature and a pressure measured by the sensor; injecting a fluid into the wellbore and into at least a portion of the formation adjacent the sensor; shutting-in the wellbore for a pre-determined shut-in period; generating a simulated model representing at least one of simulated temperature characteristics and simulated pressure characteristics of the formation during the shut-in period; generating a data model representing at least one of actual temperature characteristics and actual pressure characteristics of the formation during the shut-in period, wherein the data model is derived from the feedback signal; comparing the data model to the simulated model; and adjusting parameters of the simulated model to substantially match the data model.
