Northern Petroleum reports that the La Tosca-1 exploration well reached total depth of 2335m on the 27th August 2012 and a decision made to plug and abandon having encountered gas shows. La Tosca-1 commenced drilling operations on the 6th August 2012 evaluating the exploration potential of a gas prospect mapped from 3D seismic on the Longastrino permit.

The positive expectations prior to drilling were, to an extent, supported by wireline logging but the indications were of more limited reservoir sand development than expected from extrapolation of data from nearby wells. The considered conclusion was that the data did not provide a sufficiently strong economic case to warrant well completion and testing.
