Title (EN) OILFIELD EQUIPMENT IDENTIFICATION APPARATUS
(FR) APPAREIL D'IDENTIFICATION D'EQUIPEMENT DE CHAMP PETROLIER
Abstract:
(EN) An apparatus for identifying oilfield equipment, including the maintenance of usage histories for the equipment and recommending whether the equipment is to be used in a prospective application based on prospective application and usage history. A portable encapsulated passive circuit (9) capable of transmitting an identification code is affixed to a piece of oilfield equipment (J). The circuit is activated by a portable reader (5) which receives and decodes the identification code and transmits it to a central computer. The central computer verifies the reader (5) and the existence of the equipment (J) in the database and retrieves the usage history for the equipment. Based on the usage history, the prospective application and guidelines for usage of equipment, the computer determines the advisability of using the equipment (J) in the prospective application and transmits the recommendation back to the portable reader (5).
(FR) Appareil d'identification d'équipement de champ pétrolier procédant à la mise à jour d'historiques d'utilisation de l'équipement et recommandant l'utilisation ou la non utilisation de l'équipement dans une application de prospection sur la base d'une application de prospection et d'un historique d'utilisation. Un circuit passif portatif encapsulé (9) capable de transmettre un code d'identification est fixé à un élément d'équipement de champ pétrolier (J). Le circuit est activé par un lecteur portatif (5), lequel reçoit et décode le code d'identification et le transmet à un ordinateur central. L'ordinateur central vérifie le lecteur (5) ainsi que l'existence de l'équipement (J) dans la base de données, et il rappelle l'historique d'utilisation de l'équipement. Sur la base de l'historique d'utilisation, de l'application de prospection et des indications d'emploi de l'équipement, l'ordinateur détermine la possibilité d'utiliser l'équipement (J) dans l'application de prospection et il retransmet la recommandation au lecteur portatif (5).
