A method of creating a wellbore in an earth formation, the wellbore includin g a first wellbore section and a second wellbore section penetrating a hydrocarbon fluid bearing zone (64) of the earth formation, is provided. The method comprises drilling the first wellbore section, arranging a remotely controlled drilling device (3) at a selected location in the first wellbore section, from which selected location the second wellbore is to be drilled, and arranging a hydrocarbon fluid production conduit (70) in the first wellbore section in sealing relationship with the wellbore wall, the conduit being provided with fluid flow control means (76) and a fluid inlet in fluid communication with said selected location. The drilling device is operated t o drill the second wellbore section whereby during drilling of the drilling device through the hydrocarbon fluid bearing zone, flow of hydrocarbon fluid from the second wellbore section into the production conduit is controlled b y the fluid flow control means (76).
