Rigs for Slim Hole Drilling
Most slim wells are drilled and completed with a down-sized conventional approach using completely conventional drilling rigs, or modified workover hoists, as this is the cheapest solution. The conventional rigs may be one or two sizes smaller than if the same well were full sized, and some of them will have a "Retrofit" package of (rented) equipment installed. This applies to land, jackup, swamp, and floating rigs. In a few cases, the lower hook loads will enable wells to be drilled with a mobile (or platform) crane.
