The apparatus-and-method complexes (AMK) «GORIZONT-90» and «GORIZONT-90-VAK»were<br>developed for the horizontal well geophysical prospecting. The base of AMK is the conveyed on drill pipes<br>self-contained downhole tools of 90 mm in diameter allowing to make the geophysical surveys by the methods<br>of GR, NGR, NNLt-25, NNLt-50, AR (4 symmetrical laterals), SP, directional survey and acoustic wave<br>logging. That complex of the methods allows to solve the problems of tying of a bore hole to a geological<br>section which is necessary for exploration drilling, identifying of the reservoirs and evaluation, under the<br>conditions, of the quantitative parameters. The report demonstrates the well prospecting samples.
