““If you try and take a cat apart to see how it works,If you try and take a cat apart to see how it works,the first thing you have on your hands is a non-working cat”.the first thing you have on your hands is a non-working cat”.[Douglas Adams, The Hitchhiker’s Guide to the Galaxy, 1979][Douglas Adams, The Hitchhiker’s Guide to the Galaxy, 1979]

(personal) conclusion from ‘THE ROAD TO REALITY, A COMPLETEGUIDE TO THE LAWS OF THE UNIVERSE’ by sr. Roger Penrose: There isonly one universal physical law: ““There is NO universal physical law “.There is NO universal physical law “.

•multi-zone well, consisting of two zones A and B

•input• measured data: pressures, temperatures, productions, valve positions• production-geological data

•problem: interactions in this system during commingled production

•business incentive: improve balance production versus watering – or gassing out
