Which of the following rocks generally has the highest resistivity value? shale

Question

Which of the following rocks generally has the highest resistivity value? shale sandstone fractured dolomite solid granite Analytical reasoning: Could invasion with an oil based mud into a water bearing sandstone cause a cross over between the neutron and density porosity logs Yes No Which of the following relationships will indicate presence of hydrocarbons in a formation? Rt 0 Rt >R_x0 Rt = R_x0 Rt = R_0 Which geophysical logging tool measures the mineral component of a Formation? PEF O Sonic Caliper GR Resisativity Which of the following is not an induced radioactivity tools? Acoustic porosity tool Density porosity toot Neutron porosity tool Spectral gamma ray tool

Explanation / Answer

Solid granite is an igneous rock and has highest resistivity .

2. No

Cross over generally form due to abruptly change in density value due to gas .

3. C

Resistivity of formation must be higher invasion zone.

4. PEF.

To find dolemite or limestone.

5.
