Arckaringa Basin Drilling Update No.9
Linc Energy Ltd (SGX:TI6) (OTCQX: LNCGY) wishes to provide an update on the drilling
operations in the Arckaringa Basin. The Eba 1 vertical exploration well (PEL121) reached a total
depth of 2,959 metres on 13 March 2015 terminating in the Officer Basin equivalent of the
Cambrian Relief Sandstone with wireline logs being completed on 18 March.
As reported in previous updates, the initial pre-Permian velocities used in the seismic
interpretation were poorly controlled due to the lack of historical well intersections in the
Arckaringa Basin. In light of this, the Eba 1 well total depth was extended to 2,959 metres to
investigate high energy seismic intervals that were initially believed to be intersected at shallower
Other than small amounts of gas detected during drilling, Eba 1 has not shown significant
hydrocarbons yet despite this, the well has provided an extensive suite of geological data
primarily relating to the deeper under explored pre-Permian sediments. The data will allow Linc
Energy to remap both the Ouldburra Formation and the Relief Sandstone within the regional
seismic model to better understand the depositional and hydrocarbon generative history of the
pre-Permian section. This will also allow Linc Energy to reassess the geological interpretation
and better define the potentially hydrocarbon rich areas of the basin, allowing other opportunities
to be explored.
As a consequence of increasing the total depth at Eba 1, the “Main Hole” 2nd phase of the third
vertical exploration well, Fox 1 (PEL123), has been postponed until the next drilling campaign.
The “Pre Collar” 1st phase works at Fox 1, which involved setting 13 3/8” surface casing at a
depth of 191 metres, was completed earlier in this drilling campaign by a specialist licensed
