6.13. Solid Core Darts |
| Darts may be provided with a solid steel (or aluminium, on request) core. This is useful if it is desired deliberately to drive cement and plug the tubing, as in certain abandonment operations. It can also be useful to use such a dart as a trigger, to activate a spring mechanism for example. Small sizes can also be considered instead of a ball for release activation, especially in long horizontal or even up-inclined sections where a ball is less reliably driven. |
| These darts are described as matching the cement or acid darts with which, or instead of which, they are commonly used. This means that they are somewhat curiously described as say 20mm bore type, though they have no bore. |
