Abstract
As discussed in Chap. 5, conventional coring suffers from extremely long tripping times. The whole drilling string must be pulled out of the hole before the whole coring assembly (including inner and outer tube assembly) can be run in the hole. Similarly, following the core-drilling, the coring string must be conventionally pulled out before the drilling string can be run in the hole again to resume drilling. This causes a considerable waste of time during tripping. To address this issue, an alternative method of coring (i.e., wireline continuous coring) has been considered and applied in the petroleum industry (Walker and Millheim 1990; Randolf 1991; Deliac et al. 1991, Bencic et al. 1998; Warren et al. 1998).
Depending on the lithology, depth, core size, etc., apply, e.g., 5000 to 35,000 Ibs overpull.

Notes
- 1.
Overshot is a latching device attached down the slick line/wireline at one end and at the other end is connected to the inner tube assembly or inner drilling assembly. It is used in order to unlatch or latch the inner drilling assembly for tripping out or in (at the end or beginning of the drilling mode) or to unlatch or latch the inner tube assembly (at the end or beginning of the coring mode).
