Optimization of a Mature Oil Field by Changing Lifting System SPE 69514 - Dallas, Texas Society of Petroleum Engineers 2001 - Prado, Pablo .
All wells in Entre Lomas Area, after a initial period of natural flow, requiered an artifitial lifting system. Gas-Lift system suited very properly the field characteristic. As the reservoir pressure declined and the water-flooding expanded, it became necessary to change the lifting system progressively from Gas-Lift to Sucker Rod Pumping (SRP) or Electrosubmersible Pumping (ESP). With almost half of the wells already converted, the remaining did not appear economically attractive for conversion at the individual well basis. Therefore, a global conversion project for the remaining wells was considered, which ultimately yielded additional profit that made total replacement affordable.
