Empire Energy has provided its shareholders with an update regarding the ongoing flow testing of Carpentaria-2H well in the NT’s Beetaloo Sub-Basin.
Fluid flowback from C-2H has progressed, with 27.8 per cent of placed fluids recovered to date and water rates declining as the well continues to ‘clean up’.
It’s particularly encouraging, said Empire Energy, that C-2H water was able to ‘clean up’ which means lift the injected fluids through the well bore to surface through the 4 ½-inch casing without the need for installation of a smaller diameter 2⅞-inch production tubing or any artificial lift assistance such as nitrogen enhancement.
Gas flow from C-2H commenced on 5 August 2022 at significant but unmeasurable rates due to slug flow.
Measured gas flow commenced early on the 7 August 2022 and has stabilised at an average rate of MMscf per day across the stimulated horizontal section of 927 m with minimal decline in production rate seen to date over the first 91 hours.
The well is currently flowing at 2.5 MMscf per day.
Empire successfully places over six million pounds of proppant across the 927 m stimulated horizontal section, representing proppant concentration of 2066 pounds per foot.
Empire anticipates that there will be differing rates of production across the 21 stages because of the fluid systems and perforation strategies tested, which will be determined by 11 gas tracers and 17 water tracers that have been placed across the C-2H horizonal section.
Empire is collecting gas and water samples for gas composition and stage contribution analysis.
Furthermore, the technical data collected will assist Empire with future completion design to drive optimised well production performance. Empire intends to apply the most productive systems when stimulating the Carpentaria-3H well to be drilled later in 2022.
