Coiled-tubing fracturing (CTF) operations are proving to be a safe, cost-effective way to stimulate wells. But, the straddle packers attached to the end of the coiled tubing must be precisely placed over the intervals to be fractured or the stimulation can be compromised. A new tool has been developed to help ensure proper placement of the packers in the wellbore. A log of the casing collars is generated and then correlated to existing well logs. Once the depth corrections are made, fracturing operations can commence.
