The Estancia Dos Lagunas gas field was discovered in 1999 by Petrolera Argentina San Jorge. The field is located in the South of Argentina (Santa Cruz Province), in the Austral Basin. The structure was developed with the drilling of 16 wells, most of them producing from the Serie Tobífera. This unit is composed of volcanic and volcaniclastic rocks deposited during the rifting stage of the basin. Historically, the Serie Tobífera was considered the economic basement of the basin. However, in some cases these volcanic rocks have good reservoir properties due to primary and secondary processes. The characterization of this unconventional reservoir is far from being understood applying conventional log analysis and seismic interpretation. Therefore, the reservoir analysis has to be done using all the available information (seismic data, electrical logs, mud logging, core analyses, production tests and pressure data). The comparison of the static information with the actual dynamic behavior of the wells helps gaining a better understanding of the field. Finally, the dynamic and well production behaviors are analyzed. Lessons learned can be used for analog developments CONGTP Venara, Leandro 46290 Bahl Chambi, Gloria 46291 Cremonini, Andrés 46292 Limeres, Marcelo 806 World Gas Conference (24th. : 2009 oct 5-9 : Buenos Aires, Argentina) 45995 175856 175856 0 0 0 0 243675 BAAB BAAB 2026-03-05 200047767 0 200047767 2026-03-05 18:56:25 2026-03-05 CONGTP
