Abstract
Apparatus and probe for non-polarized contacts for resistivity measurements in drill cuttings. At least two probes having a highly conductive shell from non-corrosive metal in form of pipe and a wood and/or other fine channeled thread (grained) water filled that will be conductive when it is wet.
Claims22
An apparatus for resistivity measurement of drill cuttings, comprising:
- a. a container adapted to contain an amount of drill cuttings;
- b. a first probe, adapted to introduce electrical energy into the drill cuttings, the first probe having a conductive shell;
- a porous insert within the conductive shell, and a contact within the porous insert;
- c. a second probe, adapted to receive electrical energy from the drill cuttings;
- the second probe having a conductive shell;
- a porous insert within the conductive shell, the porous insert adapted to retain a liquid solution, and a contact within the porous insert;
- d. a power source, adapted to provide the electrical energy;
- and
- e. measurement means, adapted to measure the flow of the electrical energy.
