1. (Reservoir appraisal application) The following figure gives the schematics and pressure measurement in a discovery well in the oil zone. The gas oil contact and top of the structure were measured to be 5182 ft and 4980 ft respectively. The pressure gradients for oil, gas and water are given on the figure. Assuming a normal hydrostatic pressure regime you are asked to (18 points each part is 6 points) PNGE 316 Open Book Midterm I Spring 2023 dp dD dp dD a. Calculate the depth of WOC b. Calculate the pressures at the GOC and at the top of the structure c. Write in your own words why do we have to make all these calculations? (i.c.
