Development

Tullow focused its 2010 development on fast tracking and monetising Phase 1 of the Jubilee field in Ghana. This trend continued throughout 2011 as the fields production ramped up and in 2012 additional capital was successfully invested to remediate some Phase 1 wells and to commence the Phase 1A development. In 2013, further capital is expected to be invested in the continued Phase 1A roll out and the commencement of the TEN development in Ghana.
