Hello Soman703,
Compare the sideforces during tripping in and out when the depth of the drill string is > 7000ft.
You may have to use Normal Analysis in order to investigate this.
My guess is that the sideforce during POOH is > RIH when the string depth is > 7000ft hence the Surface Torque is also higher during POOH with rotation.
Thanks.
