Slim hole Drilling Techniques

Slim hole Drilling Techniques

Five different slim hole drilling approaches are discussed in this article. In continuous coring there was a strong drive to maximise the amount of geological information, while the shallow rotary and downsized conventional wells, with less geological involvement in the conceptual work, use conventional petrophysical evaluation. Sidetracks and coiled tubing drilling are mainly for production applications at present.

The five alternative approaches are as follows:

1 Continuous coring

The continuous coring technique depends on pipe which is almost externally flush, rotating at high speeds in a borehole only slightly larger than . . .
