Surveying Wells with No Anticipated Well Control Problems
Surveying guidelines for wells with no potential well control problems.
In Exploration, Appraisal or Development wells hole sections, where mobile hydrocarbons are not present or potential well control problems can be discounted, TOTCO surveys shall be taken at a frequency not to exceed 500 ft and on trips for bits with Magnetic Multi-Shots taken at hole section TD.
When drilling through formations where stuck pipe problems are known to exist, no surveys will be taken until the stabilisers are below the formation.
