Rialto Encounters Oil and Gas in Gazelle-P3 ST2 Well

Rialto Energy Limited provides a weekly update on drilling operations at the Gazelle-P3 ST2 Well, offshore Cote D’Ivoire as at 06:00hrs, 19 June 2012 (GMT). Since the last report we are pleased to announce that the well was successfully drilled into the planned Albian target to a total depth of 2959m MD (2684m TVDSS,) and we have encountered both oil and gas zones as anticipated. Wireline logs have been run and MDT pressures and samples taken. Oil and gas PVT quality samples were recovered from the Upper Cenomanian sands, as expected. The samples will be used to assist in the design of the Gazelle field development processing facilities. Logging continues with VSP and sidewall coring and these logging operations are expected to be concluded in the next three days.
