Steam well

Steam well

The design of steam wells is complicated by the fact that the axial stress exceeds the yield strength in compression during heating and exceeds the yield strength in tension during subsequent cooling.

As such, a design is required which incorporates post yield behaviour of both casing and connections.

A brief discussion of the issues involved in steam well design is given below, firstly dealing with the loading of the casing, and then its capacity to withstand these loads.

Casing loading Axial loads

Casing in high temperature (steam) wells is generally cemented . . .
