Operational Update

At the Tartaruga development block, Sergipe, Brazil, workover's on the 2 producing wells are in progress. Down hole pumps have arrived on site and will be installed in January 2012. The resolution of kerosene build up issues and the installation of these pumps are expected to significantly increase production at both wells. Plans are also underway for the drilling of both an exploration well and a development well at the block. The development well will target known pay horizons in the Penedo formation. The exploration well will test the Serraria formation below the Penedo and is a known producer nearby the Tartaruga block.

At the SSJN-5 block, Middle Magdalena Basin, Colombia, pre-drilling work is underway by the operator SK Innovations Corp. on an exploration well targeting the La Mocha prospect, a large structural feature in the Middle Magdelena Basin identified by the recent 3D seismic program conducted on the block. The primary target is the Porquero Formation that has been proven to be productive in the nearby La Creciente and Apamate discoveries by Pacific Rubiales.

The La Maye Block, Lower Magdalena Valley Basin, Colombia remains flooded following the rainy season in Colombia and the suspension of drilling activities will remain in effect until water levels subside and the block is accessible to drill an exploration well and test a previously drilled exploration hole that exhibited multiple oil shows (see news release dated November 20, 2009).
