Abstract
A method and related system for operating a downhole tool connected to coiled tubing comprises introducing the tool and the coiled tubing into a wellbore providing to the earth's surface a signal indicative of compression, tension and/or impact forces applied to the tool, using the signal to determine at the earth's surface the location of the tool within the wellbore, and then operating the tool.
Claims10
A method of determining the location within a wellbore of a lower end of a string of coiled tubing, comprising:
- (a) connecting a load cell adjacent a lower end of a string of coiled tubing;
- (b) introducing the load cell and the coiled tubing into a wellbore;
- (c) providing to the earth's surface a signal indicative of a force applied to the lower end of the coiled tubing;
- and
- (d) using the signal to determine at the earth's surface the location of the lower end of the coiled tubing within the wellbore.

A system for determining the location within a wellbore of a lower end of a string of coiled tubing, comprising:
- a housing adapted for connection to a string of coiled tubing adjacent a lower end thereof;
- load cell means disposed within the housing for measuring magnitude and direction of forces applied to coiled tubing;
- means for providing to the earth's surface a signal indicative of the magnitude and the direction of the forces applied to the coiled tubing;
- and
- means using the signal for providing at the earth's surface an indication of the location of the lower end of the coiled tubing within the wellbore.
