Time and time related variables in engineering

Time is the event progression starting from past to present and then, future statistically. The time-related variable is any particular value in relation to time to assess its changes on a specified (XY) plane.

Question

We have a land well where the geothermal gradient is 0.03 C/ m.
The surface temperature is 68 Fahrenheit. The well is 4000 meters deep.
1) Calculate the formation temperature at a depth of 4000 meters. The answer must be in Celsius.
The pore pressure of 4000 meters is 1.7 sg. We are unlucky and take in a kick / well kick. The volume
of the gas bubble is 3 m ^ 3 when we take in the kick. We allow the kick to migrate all the way to the
surface without closing the well.
2) What will the gas volume be at the surface?
