Abstract: An oil production arrangement comprises an oil reservoir (4), a horizontal wellbore (6) and a vertically extending production well (8). A pump (10) is positioned at the bottom of the production well (8) for pumping fluid along the horizontal wellbore and up the production well for recovery. Tubing (12) having a fluid delivery device (14) at its end is introduced into the production well and moved downwards past the pump (10) and along the horizontal wellbore as far as possible for example close to the toe (not shown) of the wellbore or at least beyond a point in the wellbore at which it is assessed that the hydrocarbon flow has terminated because of a balance between reservoir pressure and wellbore differential pressure being achieved.
