Using slant rigs in two areas of Venezuela has proved cost effective for drilling high deviated wells in heavily populated and farming regions. These rigs reduced deviated well drilling time and cost to the same level as for vertical wells drilled with conventional rigs. The primary subject matter of the article is divided into the following areas: Drilling objectives; Reservoir characteristics; Drilling techniques; Drilling parameters; Bottomhole assemblies; Drilling rigs; Drilling efficiency.
