Abstract

Application of electromagnetics as a mean of data transfer from bottom hole assembly to the surface during deep well drilling is described. Particularly, it is convenient when drilling with foam, aerated mud or air drilling in underbalance condition. Historic development of electromagnetics (EM) and of EM Measurement While Drilling (EM MWD) is elaborated briefly. Accentuated is the problem of attenuation of EM waves propagating through the rocks.

Keywords
