Located in blocks 205/21a, 205/22a and 205/26b and in relatively shallow water depths of 160 metres, Lancaster was the first basement prospect drilled by Hurricane and proved to be a significant discovery.

Lancaster has 5 well penetrations, drilled by Hurricane between 2009 and 2016, with well tests flowing light (38° API) oil to surface from the fractured basement. These well penetrations include 2 horizontal wells, which have world class productivity indexes, which will be tied back to the planned Early Production System. The Competent Person's Report (CPR) undertaken by RPS in 2017 assigns 37.3 MMstb of 2P Reserves and 486.1 MMstb of 2C Contingent Resources, giving a total of 523 MMstb to Lancaster.
