FIELD: in-situ or remote measurement and analysis of drilling mud, completion fluid, completion fluid, industrial solutions and reservoir fluids.
SUBSTANCE: method involves taking liquid samples from predetermined liquid sample taking points where drilling mud, completion fluid, completion fluid, industrial solutions and reservoir fluid flow or are stored; introducing the samples in chemical analyzing microfluid system linked to computer device; performing one or several selected tests in said microfluid device with the use of test result detecting and data creation means; converting said data with analytic test results obtaining; monitoring said results to control selected parameters of drilling operation, reservoir penetration and operation.
EFFECT: decreased amount of sample and test reagents.
