A long spacing (64\", added by this adapter) reads deeper into the undisturbed formation, giving a more representative bulk resistivity at the cost of coarser vertical resolution. Running both together and comparing the two curves helps identify fluid invasion, casing effects, or thin beds being averaged out, and gives more confidence in the true formation resistivity used for porosity, salinity, and lithology interpretation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e 44.5 mm (1.75\") diameter (matches the GE0809 probe body) × 1003 mm (39.5\") length, 2.5 kg (5.5 lb).
