been canceled.
The invention relates to a method of measuring earth
formation properties using a sensor disposed in a drill bit.
Appellants identify on page 4 of the specification that the
method makes use of a drill stem which has two instrument
carrying sections with a drill bit on the distal end. On page
5 of the specification, Appellants state that the drill bit
body contains a sensor which transmits microwave electro-
magnetic wave energy into the formation directly in front of
the bit. Further, on page 7 of the specification, Appellants
identify that the sensor receives the microwave energy
reflected off of the formation ahead of the drill bit. This
reflected signal can be indicative of the water content of the
formation and is either analyzed or stored for later analysis.
Independent claim 11 is illustrative of the invention.
A method for determining the presence of hydrocarbons in
a relatively thin layer of an earth formation comprising the
steps of:
drilling into said earth formation using a rotatable
