The first step before before spudding any well is well well programming. programming. An effective well programming before undertaking drilling of an exploratory well is must. This programming programming of the well which which covers all all geological and and other technical technical data and serves as guide during the course of drilling is termed as “geotechnical “geotechnical order”. Blue print of well execution Contain data likely to be encountered during drilling & precautions to be taken. Guidance to Geologists, Drillers, Chemists & other Service Groups. Jointly prepared by Geology, Drilling, Drilling, Mud services, services, Logging, Well Well Services.
