초록

A tool changes the electrical conductance across a nonconductive separation in a string of electrically conductive casing in a well located in the earth. The tool is for transmission of data up the well. The casing has at least one inwardly extending landing shoulder for the tool. The tool has a housing elongated between first and second ends. The housing has a first contact for electrical connection to the casing on one side of the nonconductive separation. The housing has a second contact spaced from the first contact for electrical connection to the c...
