Title (EN) BOTTOM HOLE ASSEMBLIES FOR DIRECTIONAL DRILLING
(FR) ENSEMBLES DE FOND DE TROU POUR FORAGE DIRECTIONNEL
Abstract:
(EN) Directional drilling is an extremely important area of technology for the extraction of oil and gas from earthen formations. The technology of the present application relates to improved positioning elements for directional drilling assemblies. It also relates to drilling directional wellbores using the guidance positioning members of the present technology.
(FR) Le forage directionnel est un domaine extrêmement important de la technologie pour l'extraction d'huile et de gaz à partir de formations terrestres. La technologie de la présente invention concerne des éléments de positionnement améliorés pour des ensembles de forage directionnel. L'invention concerne également le forage de puits de forage directionnels à l'aide des éléments de positionnement par guidage de la présente technologie.
