Title (EN) SYSTEM AND METHOD FOR DATA TELEMETRY AMONG ADJACENT BOREHOLES
(FR) SYSTÈME ET PROCÉDÉ DE TÉLÉMÉTRIE DE DONNÉES ENTRE DES TROUS DE FORAGE ADJACENTS
Abstract:
(EN) An active downhole antenna located in a borehole receives electromagnetic (EM) telemetry transmissions from sources in adjacent boreholes. The antenna comprises a processor operable do decode and measure signal to noise ratio of received transmissions. Data received at the active antenna is transmitted to surface using a high-speed data communication network. The active antenna may handle data communications from multiple downhole EM telemetry transmitters.
(FR) Selon l’invention, une antenne active de fond de trou située dans un trou de forage reçoit des transmissions de télémesure électromagnétique (EM) à partir de sources dans des trous de forage adjacents. L'antenne comprend un processeur utilisable pour décoder et mesurer le rapport signal sur bruit des transmissions reçues. Les données reçues au niveau de l'antenne active sont transmises à la surface à l'aide d'un réseau de communication de données à haut débit. L'antenne active peut gérer des communications de données provenant de multiples émetteurs de télémesure EM de fond de trou.
