Ithaca Energy Inc. (LON:IAE) (TSX:IAE) has successfully completed the drilling of a water injection well for the Athena field development.
Well 14/18b-A1 intersected 325 feet (on a true vertical basis) of net reservoir, exceeding the net reservoir requirements for water injection to support initial gross production from the field at approx.22,000 barrels of oil per day (bopd)(source Sproule) from Q4 this year. The drilling unit will now proceed to drill a fourth production well and complete the three existing suspended wells on the field as well as the new producer and injector, from the same surface location.
The well has been drilled as a future water injector, down flank from three successful appraisal wells. This well is the first of a 180 day campaign of drilling and completion activities prior to subsea equipment installation and 'hook-up' of the Floating Production Storage and Offtake vessel (BW Athena). Operations on the well have met all key objectives.
The target formation (Top Scapa A, formally Upper Leek Sandstone), and principal reservoir unit of the Athena field, was encountered at 9,325 feet True Vertical Depth Subsea ("TVDSS"), in line with prognosis. Wireline logs have confirmed a multi-layer permeable sandstone and shale gross section of 820 feet of which 325 feet is net reservoir on a true vertical basis. Average porosity across the reservoir section is excellent and tests indicate good fluid mobility in all selected sandstone units tested. Formation pressure measurements lie close to known aquifer pressures recorded in earlier wells, confirming lateral and vertical communication throughout the field.
The well has been fully cased and temporarily suspended pending batch completion of all five wells (4 producers, 1 water injector) once the final production well has been drilled. The rig will return to the well towards the end of the campaign to perforate and run completion equipment in preparation for first production from the Athena field.
