Product Description

This product carries out functions similar to wireline, but with added benefits. Wireline is a cabling technology that is also used in oil and gas well intervention. The advantage that coiled tubing has over wireline is the ability to pump chemicals through the coil and to push the coil into the hole, whereas wireline depends on gravity for this function.

In addition, coiled tubing can be a cheaper alternative to conventional drilling string. One reason is that it allows the continuous feeding of the tubing into the hole without constant interruptions. These interruptions are the result of the need to constantly add new drill pipe every time the hole is deepened. Frequent interruptions can prove to be quite time-consuming, and increase the rig time required.

Using coiled tubing can eliminate the drill string-feeding time by being continuously fed, which is a major economic advantage. The need for a lifting device, referred to as a "derrick, " can also be eliminated. This can further cut back on price by reducing the hourly cost of the rig.
