Abstract
The porosity of a formation surrounding a cased well is determined from a shear wave log of the formation. Shear wave velocity is derived from the log and formation porosity is identified from a predetermined correlation between core-derived porosity for the type of formation traversed by the cased well and shear wave velocity.
