Abstract (en)
[origin: US4664189A] A method and device are provided for carrying out measurements and/or operations in a well. In this method at least one tube is used which includes at least two parts one of which is an upper tubular part and another of which is a lower tubular part, an extension having an upper end and a lower end and an instrument for carrying out measurements and/or operations fixed to the lower end of said extension. The method involves the steps of: (a) fitting said extension equipped with said instrument to the lower part of said tube, (b) fitting the upper part of the tube above the lower part of the tube thereby providing greater penetration into the well of the assembly formed by the lower tube, the extension and the instrument and (c) effecting movement of the extension and of the instrument with respect to the tube to a position of said instrument where the measurement and/or operations may be carried out.
