[{"type":"text","content":"\n\n\n/NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR\n DISSEMINATION IN THE UNITED STATES/\n\n\nCALGARY, Oct. 9, 2013 /CNW/ - DualEx Energy International Inc. (\"DualEx\"\n or the \"Company\") (TSX-V: DXE) today announced the following\n operational update regarding the Company's BHN-1 exploratory well on\n the Bouhajla Permit in northeastern Tunisia.\n\n\nAs was previously announced, DualEx has penetrated 245 metres of the\n target Abiod chalky limestone reservoir section in the BHN-1 well.\n During drilling, elevated levels of C1-C4 (methane-butane) were noted in the mud log with indications of both\n open and healed fractures noted in the drill cuttings. Fluid losses\n during drilling of between 0.8 and 3 cubic metres per hour were\n encountered throughout the Abiod.  Hole stability issues below the\n intermediate casing string were such that the Company found it\n necessary to case the wellbore, which was then followed-up with\n cased-hole neutron/sonic/gamma logs for initial evaluation purposes.\n\n\nIn September, the Company was able to source a pulse-neutron logging\n tool, previously unavailable in country, to determine pore saturations\n within the Abiod.  The results of the pulse-neutron log are indicative\n of elevated hydrocarbon saturations throughout the Abiod section, with\n no indication of having intersected a water contact.  Typically, Abiod\n reservoirs rely on naturally-occurring fractures for the production of\n hydrocarbons. The non-fractured Abiod section in BHN-1 has low\n permeability; however several zones of enhanced permeability due to\n apparent natural fractures and faulting have been interpreted from the\n logs and confirm expectations based on 3D seismic interpretation of the\n Bouhajla North structure. DualEx is focused on completing and testing\n these zones of enhanced permeability.  Initially, the Company planes to\n perforate two zones near the bottom of the logged interval (six metres\n of perforations for each) for flow and testing analysis.  After\n perforating, an acid wash of the perforations will be carried out\n followed by an acid squeeze into the formation.  The BHN-1 completion\n protocol will be similar to that employed by the operator of the Sidi\n el Kilani oil field located twenty-five kilometres to the east of\n BHN-1.\n\n\nThe Com...
