If one can rely on the information contained in the Cohen Report,(page 26) it is clear that "Temblor West" consists of
700 acres(Opus) and 500 acres (TIV) in S. Belridge. "Temblor East" consists of 160 acres in Edison. The question then becomes
where is the TIV 500 acre in relation to the known location
of the Opus 700 acres (map 456)?
Also per the Cohen report, TIV's plans for exploiting the
Diatamite zone is for horizontal drilling a la Aera. And
to prepare for this it makes sense that they must first
drill vertical test wells to determine the areal extent,
thickness and dip of the pay zones, since on the West flank they
are much thinner than on the main structure 400'+/- vs
1000'-2000').
I haven't looked into the Edison operations ,so have no opinion.
I do notice that the number wells pumping there at any given
time seems to be directly proportional to the current price of oil.
Re the rigs, it would appear that the production rigs are
busy doing more contract work (geothermal) than drilling the the TIV/Opus holdings. Fund raising?
