In HW #$04,$ five barrels of the formation fluid entered the wellbore due to too fast tripping out. If the CSIP is $260$ psi and the maximum casing pressure when the formation fluid is at the surface is $1,750,$ use the volumetric method to circulate the kick out.

Note I: Pressure increment and safety factors are $100$ and $200$ psi $,$ respectively.

Note II: The bit is plugged.

HW#$04$

We are drilling in the ${8\mathrm{.}5}^{\text{'}\text{'}}-$hole section of a vertical well at $11,000ft.$ The previous casing string $(9-\frac{5}{8^{\text{'}\text{'}}},47lb\frac{s}{f}t)$ was run and cemented at $8,500ft.$ A kick has been detected. $8$ bbls of $11$ ppg mud has been gained in the mud pit. The well was shut in and casing pressure was recorded $($Table $1).$ The shut$-$in drill pipe pressure is $230$ psi $.$ The drill string consists of $600ft6-\frac{1}{4^{\text{'}\text{'}}}DC,93\mathrm{.}5l\frac{b}{f}t,$ and $5^{\text{'}\text{'}}DP,19\mathrm{.}5l\frac{b}{f}t.$ Reduced Circulating Pressure $($RCP$)$ is $360$ psi $.$ The mud pump is a triplex single$-$acting pump with the following specifications:

Length of liner: $14$ inches

Piston diameter: $6$ inches

Rod diameter: $2$ inches Volumetric efficiency: $\%97$
