are used to promote the relieving of pressure in the segments of the horizontal well allowing even in the case of long lengths of such segments of horizontal well a uniform maximized fluid intake the horizontal producing ring wells 8 10 12 or 14 may present pathways that are easier to drill with improved utilization of some of the characteristics of the reservoir the horizontal producing ring wells 8 10 12 or 14 may be shortened with production lines on the surface that link some of the wells in the group of vertical producing wells 7 9 11 or 13 to the central controller unit e dividing a horizontal producing well 8 10 12 or 14 into two the injection of water preferably with the addition of polymers from the central controller unit e to the horizontal injection well 6 forces the moving fluid front f inside the reservoir r to move the oil towards the first horizontal producing well 8 until this first horizontal producing well 8 begins to produce practically water and as of that moment this horizontal producing well 8 is converted into an injection well with continuity of the movement of the oil towards the second horizontal producing well 10 until water is produced to be then converted into an injection well and so on in succession as far as the fourth horizontal producing well 14 sweeping the entire reservoir r if the sweep v does not take place in the anticipated manner one of the annular horizontal wells 8 10 12 or 14 may at the same time be producing in a specific segment and injecting in another segment of the same well with the insertion of injection and production.
