Electrical resistivity of geologic materials
Conductivity is given in units of Siemens per metre, or S/m. Units of millisiemens per metre (mS/m) are often used for small conductivity values; 1000mS/m = 1S/m. So 1mS/m = 1000 Ohm-m, since resistivity and conductivity are inversely related. The electrical conductivity of Earth''s materials varies over many orders of magnitude.

CP Coke (Calcined petroleum coke) is a high purity carbon material produced by heating green petroleum coke to drive off moisture, volatile matter, and impurities and to increase its electrical conductivity. Nearly 75% of Calcined petroleum coke is used in primary aluminum industry, the rest of them is for steel and chemical industries.
Coke Carbon - an overview | ScienceDirect Topics
Oil and natural gas are large carbon resources, too. All of them have been used for coke making, except anthracite and natural gas, but only a relatively few coal grades are considered as good coking coals for metallurgical coke. Large deposits of good coking coals are found in Australia, Canada, United States, South Africa, Russia, and China.
Electrical resistivity of carbon granules in a fluidized bed
were petroleum coke, calcined coke and graphite having Tyler mesh sizes from -65 to +250 and in some cases, from -65 to +400. As the gas flow rate through a bed was increased from zero, the resis tivity remained constant at the relatively low value of the settled bed re sistivity. When the flow rate approached the minimum fluidization rate,

Static Electricity in Fuel Handling Facilities
For significant electrical charges to develop, the bodies must become and remain insulated with respect to each other. In the petroleum industry, the static charge results from contact and separation that takes place in a flowing liquid. Also, the rate of electrostatic generation in a pipeline or hose increases as the length increases.
