A group-of-reservoirs-borehole-choke simulator has about 30 parameters controlling its elements. It allows investigating and creating methods for well production tests, for testers on tubing or logging cable accounting for their specific features. The simulator allows investigation of influence of 1) reservoir properties upon apparent permeability, 2) degassing of oil in the zone near a borehole upon phase permeability, 3) perforation quality and extent upon results of measuring, 4) interflows between layers upon measuring, 5) presence of high permeability layer upon depression value near bottom, 6) presence of choke upon functioning of the whole system etc.

The same simulator allows to investigate the processes which take place on fountain production of a well in order to find an optimum regime of its exploitation to increase production of the well by means of changing choke diameter, proper perforation and flow rate. The simulator may also be used for theoretical researches bound with injection wells and hydraulic fracturing.

The solution is presented in graphical form on the screen being a set of izobars inside a reservoir, diagrams of bottom hole pressure and flow versus time. Optionally user can enable transit pressure curves to be processed according to Horner’s method.
