Candax Reports on Robbana Work-Over

Source: www.gulfoilandgas.com 6/13/2012, Location: Africa

Candax Energy reports that subsequent to the Robbana work-over, the well was re-opened and resumed production. Production returned to levels below levels before the well was shut in for the work-over. After conducting remedial work to determine the reason for the modest production, it was decided to stop production to do additional remedial work on the well. A fault detected on the pump was corrected and the pumping process then resumed. The production is expected to gradually reach the same level than before the work over.

The work-over was successful in re-perforating the upper zone; however, the re-perforation of the lower zone has not resulted in production from that zone. The work suggests that the well will return to production levels seen before the work over but will likely not reach the targeted production level of greater than 100 barrels per day.

The positive element obtained from this work-over is that there is significant production from a narrow layer of oil consisting of only a few meters. The development of the lower layer, with a much larger thickness, is still to be done. While we are working to produce Robbana-1 at the maximum level possible, we are reprocessing and re-interpreting the 2D seismic to better understand the structure of this field for its 2 horizons.
