The actual value of differential pressure is
ΔPDepthofMaximumΔP=(MWCasingPoint-FPDepthof MaximumΔP)(0.052)(DepthMaximumΔP) ( Eq.4)
243 Intermediate Casing Point Determination
If the tentative casing point is a drilling liner point,
the next objective is to decide where the
intermediate casing is to be set. The actual
intermediate casing setting depth is determined by
solving for the mud weight which can be in the hole
at intermediate casing point so as not to exceed the

When a drilling liner is to be used with an
intermediate string, the drilling liner can probable
be set anywhere within and interval of hole. The
shallowest depth for a drilling liner has already
been established. The deepest depth to which a
drilling liner can be set can only be calculated
once the intermediate casing setting...
