Beetaloo Project update
Operations continue at the Kyalla 117 well near Daly Waters in the Northern Territory.
The well was successfully fracture stimulated and flowback operations commenced in early October with enough gas to sustain a flare, however extended production testing to assess the quality of the resource requires a measurable gas breakthrough to occur.
Origin General Manager for Beetaloo and Growth Assets, Tracey Boyes said, “Well data collected to date is positive with core analysis indicating mature hydrocarbons and good permeability, and mud logs indicating the presence of liquids-rich gas.
“Our analysis of data from current operations is showing greater pressures in the well than in the reservoir, due to the saline content and density of the flowback fluid.
“It is not unusual in shale plays for the salinity and density of the flowback fluid to increase as salt easily migrates from the surrounding formation.
“Our plan is to introduce nitrogen to lift the fluids in the well and lower pressures to assist with achieving a gas breakthrough, which is a common technique we carried out on the successful Amungee well in 2016.
“Work both on and off site will now focus on continuing to flow back the well while planning this additional work, likely to occur in early 2021 following the wet season.The option to temporarily shut in the well is being considered as part of this activity,” Ms Boyes said.
Origin will continue to analyse data from the well to inform future activities as the joint venture continues to work towards achieving a successful outcome for the Kyalla well. For more about the Beetaloo project visit www.originbeetaloo.com.au.
