Abstract
A method for determining characteristics of a tubing deployed in a wellbore includes 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.
