Claim One:
1. A method for determining characteristics of a tubing deployed in a wellbore formed in a formation, comprising: positioning a first sensor within the wellbore, wherein the first sensor generates a first feedback signal representing a downhole parameter measured by the first sensor; positioning a second sensor adjacent a surface of the formation in which the wellbore is formed, wherein the second sensor generates a second feedback signal representing a surface parameter measured by the second sensor; generating a simulated model representing a simulated surface weight indicator of the tubing, wherein the simulated model is derived from at least the first feedback signal; generating a data model representing a measured weight indicator of the tubing, wherein the data model is derived from the second feedback signal; comparing the data model to the simulated model; and adjusting a parameter of the simulated model to substantially match the simulated model to the data model.
