FIELD: oil and gas industry.
SUBSTANCE: method involves identification of a variety of processes and their parameters; with that, processes include drilling and sampling processes and parameters include drilling and sampling parameters. Also, the method involves processing of parameters for each of the processes by means of a special modelling processor creating forecasts related to formation sampling. With that, special modelling processor includes at least one of simulators of a well shaft hydraulic system, a simulator of filter cake of drilling mud, a simulator of formation stream or a simulator of tool feedback. The method also involves classification of forecasts related to formation sampling based on at least one of sample fluid medium quality, duration of sampling process, productivity of sampling process or cost of sampling, and planning of sampling operation based on classified forecasts.
EFFECT: improving efficiency or productivity of a sampling operation of formation fluid medium or operation.
