LONDON -- The Viodo Marine 4 vertical appraisal well (VIM-4) in Marine XI block, offshore the Republic of Congo, has tested at a combined maximum flow rate of approximately 2,600 b/d of oil and 7 MMcf/d of gas following two drill stem tests, SOCO International says.
In the first drill stem test from the deeper Carbonate section, between 2,240 to 2,273 m (7,349 to 7,457 ft), the well flowed at initial post-acid rates of approximately 2,600 b/d of oil and 2.5 MMcf/d on a ¾-in. choke. Flow rates stabilized at approximately 1,100 b/d of oil on a ½-in. choke after an approximate seven hour flow period. A test of the upper Carbonate section, between 2,205 and 2,230 m (7,234 to 7,316 ft), flowed at post-acid rates of approximately 4.5 MMcf/d
The well objectives are to further delineate the field, gather data that would allow the 3D seismic to be used to map the distribution of reservoir quality limestone, and to test the effectiveness of a completion strategy that could be applied to high angle development wells.
The company will now incorporate the well and the reprocessed seismic results into a 3D model to assess the commerciality of the accumulation. The well will be plugged and abandoned.
