A 12,000 ft deep well described below is being produced at a rate of 1100 STB/d oil and 0.005 mmscf/d gas. The average reservoir pressure is 4000 psi. The well will be equipped with 3.5 in. tubing ( = 0.001, I.D. = 2.992 in.), the surface tubing pressure is 100 psi, and the surface tubing temperature is 100 F. Oil & gas properties are given in the below charts and the table. Calculate the pressure and temperature vs depth curve starting from the surface using a fixed length interval of 200 ft. You may stop after calculating pressure at 400 ft. The accuracy of the pressure calculations need to be better than +/- 5%. The questions below are meant to provide you with guidance: 1. 1) What section in the book will you find the instructions for these calculations. 2. 2) What is the flow regime in this well. 3. 3) What method do you have to use to calculate the pressure 4. 4) Now continue and calculate the pressure and temperature versus the depth curve as specified above. Make sure you check the accuracy of your calculation versus the required accuracy of +/- 5%. Some questions you need to consider: . What is your approach to calculating the temperature . What is your approach to calculating the pressure o How do you calculate your first guess o How do you calculate your first pressure with proper equations How do you check your accuracy
