Gas flow rates from each of the Mnazi Bay wells exceeded Artumas expectations for production potential. The natural gas flow rates were also accompanied by liquid hydrocarbons that flowed during the production tests. The produced liquids range from 25 to 27 degrees API gravity, which is normally consistent with medium-gravity crude oiI. Cumulative production of hydrocarbon liquids during the production testing of MB-2, MB-3 and MS-1X totaled 89 barrels.
Artumas is undertaking a program of independent laboratory testing to better understand the nature of the liquid hydrocarbons produced from its Mnazi Bay wells.
Artumas is currently gathering 2D seismic data over the Mnazi Bay Concession, which will be used to define the specific area over which a 3D seismic survey will be conducted. The 3D seismic will provide important information about the Mnazi Bay reservoir, which will improve development planning and ultimately lower the cost of development of the field. 3D seismic gathered over other areas of the Mnazi Bay concession will significantly improve the imaging of exploration leads and prospects, which will in turn improve the chance of success for future exploration wells to be drilled on the Concession. This 3D seismic survey will be initiated during the second half of 2007 with exploration drilling planned next year.
A summary of the recent long term production testing from the completed interval in each of the Mnazi Bay wells is as follows:
Mnazi Bay-2 (MB-2) Production Testing
Mnazi Bay-3 (MB-3) Production Testing
Msimbati-1X (MS-1X) Production Testing
The production of hydrocarbon liquids during extended production testing is, in and of itself, an encouraging development. Further work remains to be completed to determine (i) whether the hydrocarbon liquids reside in a separate phase (crude oil) within the reservoir, and (ii) whether the hydrocarbon liquids are present in commercial volumes. The planned seismic acquisition and subsequent drilling program will help to provide answers to these important questions.
