Carbonate reservoirs of the deposits 301-303 present specific challenges for the development due to a well-developed system of vertical and horizontal fractures and presence of deconsolidated reservoir zones. The analysis of pilot operations conducted in this area showed that horizontal and directional drilling remain the most efficient techniques for the development of such reservoirs out of all methods tested although many issues related to rapid increase of water cut in horizontal wells remain unsettled.
