| Abstract: | The extra pressure produced by non-cementing casing when T and P changes is derived by strain analysis. Futhurmore the critical pressure of non-cementing casing under the action of inside and outside confining pressures, is achieved by use of minimum potential energy principle. A new discriminant is given. |
