A well was drilled to a depth of 7,800 ft. At this depth a gas-bearing sandstone was interpreted on the wireline log. A test was then run that showed gas at a static pressure of 3,435 psig. The gas sample was measured to have a gas gravity of 0.6075. A water sample taken from a sandstone above the gas-bearing zone tested to be 25,000 ppm. These are known to be normal conditions for reservoirs at this depth. The temperature gradient in the area is 1.1 degrees F/100 ft. Standard surface conditions are 14.65 psi at 77 degrees F. Use the data from both the Gas Gravity (spreadsheet 5-2) and Water Density (spreadsheet 5-1) Spreadsheets to answer the following questions.
