The parameter term for resistivity measurement of a rock saturated with 50% of saline water and 50% of Hydrocarbon is ………… ........................ …… 4. Rt, Rw and Sw 5. Simandoux Method, Indonesia Method and Structural Shale Method II. EXPLAIN THE ANSWER ABOVE ABOUT THE GR LOG 1. What three (3) major radioactive elements does the gamma ray tool respond to? Potassium, Thorium and Uranium 2. What type of activity (high, medium, or low) do carbonates, sands, and shales typically exhibit? GR min : minimum gamma ray (carbonate) GR max: maximum gamma ray (shale and sands) 3. How does an increase in clay content affect the gamma ray response? Pada lithologi clay, nilai gamma ray log menunjukkan nilai yang besar karena pada clay mengandung banyak unsur radioaktif yang besar seperti potassium, thorium dan uranium.
