Shut-in casing pressure can be affected by several factors, including the temperature and pressure of the fluids within the well, the integrity of the casing and cement, and any gas or fluid migration from surrounding formations. Additionally, changes in reservoir pressure due to production or injection activities can influence shut-in pressures. Environmental factors, such as temperature fluctuations, can also play a role in pressure changes. Regular monitoring and maintenance are essential to ensure accurate pressure readings and well integrity.

When the pressure of an explosion expands and tears the casing of the explosive, it results in the release of the explosive material and the creation of a shockwave. This can lead to widespread damage and destruction in the surrounding area, depending on the size and strength of the explosion.
In order to reduce material stresses. Under pressure, a casing has to seal against the pressure inside the casing and atmosphere. As plant pressures increase, besides geometrical designs differences, the other basic items left for the designer to minimize stresses are material selection and casing thickness. A double casing provides another option since it essentially places an intermediate casing in between the single casing. In that way, one casing seals against steam pressure and a lower partial pressure, a few stages downstream of the inlet stage, and then the intermediate casing seals against this lower pressure an ambient pressure.
