      “igure  2...   Reproduction  of a  typical  log  heading.  Information  on  the  header  about  the  resistivity  values  for  drilling  mud  (R,,)  and
             mud  filtrate  (Ryp)  are  especially  useful  in  log  interpretation  and  are  used  in  calculations.
             NOTE:  Sometimes,  as  in  this  example,  a  value  for  the  resistivity  of  mudcake  (R me)  Is  not  recorded  on  the  heading.
