FORMATION TESTER (D# WPC-22) ABSTRACT A well tool for developing measurements of pressure or temperature in a well bore comprising an elongated well tool which utilizes a coherent beam of light which is applied to the ends of separate fiber optics and the other ends of the fiber optics are detected to produce an electrical signal in response to differences between the outputs of the fiber optics to the detector. For measuring pressure, one fiber optic may be coiled in a temperature insulated chamber and sense a discrete sample from the earth formations while the other fiber optic is coiled in a temperature insulated reference pressure chamber. In another embodiment both fiber optics are subjected to pressure samples from longitu- dinally spaced locations of the earth formations. In still another embodiment, the fiber optics are subjected to the temperature in the bore hole at longitudinally spaced loca- tions for obtaining a temperature gradient measurement.
