Any changes in pressure and temperature can unseat a packer used in well completions.

Any changes in pressure and temperature can unseat a packer used in well completions. Correct Answer True

The statement is true. Changes in pressure and temperature can unseat a packer if the packer is not properly seated in the casing wall. With changes in pressure and temperature expansion or compression takes place and if this happens then the elastomers or rubber element may unseat from its place.

Consider the following statements and choose the correct answer:
1. A direct proportionality exists between vapour pressure and the concentration of water vapour in the atmosphere
2. Relative humidity is an expression of the ratio of the actual vapour pressure of the atmosphere when saturated at the same temperature
3. A rise or fall in temperature with no change in vapour pressure will cause a drop or rise, respectively, in relative humidity
4. A rise or fall in vapour pressure with no change in temperature will be accompanied by a rise or fall, respectively, in relative humidity
Relative humidity is given by (where pv = Partial pressure of water vapour, pb = Barometric pressure, ps = Pressure of saturated air, pd = Pressure at dry bulb temperature, pw = Saturation pressure corresponding to wet bulb temperature, and μ = Degree of saturation)
