Explanation / Answer

82. Oil and gas are chiefly insulators with very low conductivity

83. Invaded zone is invaded by drilling fluids. The drilling fluids have high pressure as compared to the formation fluids and thus invade the formation into the pores.

84. Formation water at depth is mostly brackish but in a zone of deep fresh water aquifers fresh water can also be encountered.

85. Water saturation represents percentage of water present in the pores of a formation.

86. Core analysis doesn't involve the measurement of basin geometry. But it tells about the lithology, it's porosity and permeability.

87. Wireline logging is the downhole acquisition and recovery to surface of reservoir formation material.
