Title (EN) SYSTEM, PROGRAM PRODUCTS, AND METHODS FOR CONTROLLING DRILLING FLUID PARAMETERS
(FR) SYSTEME, PRODUITS-PROGRAMMES ET PROCEDES DE COMMANDE DES PARAMETRES DE FLUIDES DE FORAGE
Abstract:
(EN) Embodiments of systems (22), program products (72), and methods for controlling drilling fluid parameters are provided. These embodiments, for example, provide dynamic density control with highly adaptive, real-time, process-control and are scalable to any rig, large or small, on land or water. Combined static and dynamic stresses and displacements can be determined continuously at strategic locations in and around the wellbore of a well (71) so that insitu and operational induced pressure window limitations at specific weak-points or other locations of interest are controlled.
(FR) L'invention concerne des modes de réalisation de systèmes (22), de produits-programmes (72), et de procédés de commande des paramètres de fluides de forage. Lesdits modes de réalisation permettent, par exemple, une commande de densité dynamique avec une commande de traitement en temps réel hautement adaptative, et peuvent être adaptés à n'importe quelle plateforme de forage, de grande ou de petite dimension, sur terre ou en mer. Des contraintes et des déplacements statiques et dynamiques combinés peuvent être déterminés de manière continue au niveau d'emplacements stratégiques dans et autour du trou de forage d'un puits (71) de manière à régler les limitations de pression induites in situ et opérationnelles au niveau de points faibles spécifiques ou d'autres emplacements d'intérêt.
