Title (EN) CONTROL METHOD FOR USE WITH A STEERABLE DRILLING SYSTEM
(FR) PROCEDE DE COMMANDE POUR SYSTEME DE FORAGE ORIENTABLE
Abstract:
(EN) A control method for use with a steerable drilling system comprises the steps of inputting parametric model data representative of drilling conditions and using the data to determine achievable drilling directions.
(FR) L'invention concerne un procédé de commande pour un système de forage orientable. Ce procédé consiste à enregistrer des données de modèle paramétrique représentant des conditions de forage; puis à utiliser ces données de manière à déterminer les orientations de forage réalisables.
