A well completed with $10,000$ ft of $27/8"$ tubing is flowing at a rate

of $600$ B$/$D with a gas$-$liquid ratio of $1\mathrm{.}0$ MCF$/$BBL$.$ Assuming a tubing

head pressure of $300$ psi,. Calculate the bottomhole flowing pressure.

$2.$ For the above well $1,$ calculate the variation in bottomhole flowing

pressure at various rates of $50,100,200,400$ BOPD
