Zastosowanie odwiertów multilateralnych na złożach ropy naftowej w późnej fazie eksploatacji
(2007) Stopa, Jerzy; Rychlicki, Stanisław; Wojnarowski, Paweł
Multilateral systems as compared with the conventional wells offer a number of advantages, e.g. possibility of increasing resources through opening a part of the unproduced reservoir, acceleration of production, lowering the cost of realization of exploitation project owing to the use of a common vertical section for a number of horizontal or inclined branches. Thanks to the high oil price, now this type of wells is an attractive alternative of opening deposits at any stage of exploitation. The technical efficiency of a multilateral well was assessed on the example of a partly depleted oil field in Poland. Using computer simulation methods, a comparative analysis of vertical, horizontal and multilateral wells was carried. Moreover, the efficiency of these wells was evaluated. According to the simulation results, the use of a multilateral well significantly increased the production and uniform depletion. This was due to the fact that a large part of the field was being exploited.
