摘要

METHOD OF RECEPTION AND / OR TRANSMISSION OF INFORMATION IN A WELL DRILLED IN A GEOLOGICAL FORMATION BETWEEN A FIRST LOCATION AND A SECOND LOCATION, APPLIANCE FOR RECEPTION AND / OR TRANSMISSION OF INFORMATION IN A DRILLED POOL IN A PERIODIC HOLE DRILLING IN A PERIODIC HOLE DRILL. , METHOD FOR DETERMINING THE CONDUCTIVITY PROFILE OF A WELL TRAINING BETWEEN A FIRST LOCATION IN A SURFACE AND A SECOND LOCATION IN A DRILLED HOLE, AND DEVICE FOR DETERMINING THE CONDUCTIVITY PROFILE OF A TRAINING OF A TRAINING IN A TRAINING TRAINING SURFACE AND A SECOND LOCATION IN A DRILLED HOLE. The invention provides a method of receiving and / or transmitting information in a well drilled in a geological torform between a first location and a second location, the well comprising a coating in communication with the geological formation. The method comprises arranging a first transducer at a first location, and arranging a second transducer at a second location. an electrical signal is transmitted between the first and second transducers.
