f New Completion Design Facilitates Well and Reservoir Surveillance in Beam Pumped Wells in South Oman

Most oilfields in South Oman comprise mature, heavy oil<br>reservoirs with sub-hydrostatic pressures. Wells need be put<br>on artificial lift since the beginning and different artificial lift<br>methods have been deployed. Rod driven beam pump is one of<br>the common artificial lift methods used and currently more<br>than 1000 beam pumped wells are in operation contributing to<br>about 30% of production from south Oman fields. These<br>oilfields, in general, are geologically very complex and<br>extremely heterogeneous due to the presence of large number<br>of faults and fractures.
