FIELD: oil industry.
SUBSTANCE: invention relates to a device for measurements, relating to search for oil and gas in directed drilling. Disclosed is a system for directed drilling, comprising: an optical computing element (105; 405; 805), located in housing (401), configured for attachment to drill string; window (402) in housing, configured to receive light from outside housing so that light is directed from outside of drill string to optical computing element, when housing is installed on drill string; and analytical unit (420), intended to provide a signal based on signal output from optical computing element in response to receiving by optical computing element light from outside of drill string. Provided signal is intended for directed drilling based on characteristics of area defined by signal output from optical computing element.
EFFECT: high accuracy of identification of productive zone.
